If researcher Joan Casey pulled Oklahoma Google search data for the month of June, she would expect to see an increase in searches for anxiety. That's because on June 15, a magnitude 4 earthquake hit Oklahoma.
Oklahoma isn't an earthquake-prone area, naturally. However, over the past decade, there's been a sharp increase in wastewater injection wells, which store wastewater produced from oil and gas drilling. The state has roughly 3,800 disposal injection wells, according to the Oklahoma Corporation Commission.*
The fluid pumped underground can change alter pressure in faults, spurring quakes.
Oklahoma had some seismic activity prior to 2008, with one or two earthquakes (magnitude 3 or higher) a year. But that jumped in 2009, going from two in 2008 to 20 in 2009. In 2015, Oklahoma experienced 887 magnitude 3 or higher earthquakes, according to the U.S. Geological Survey.
Between June 2008 and July 2017, Oklahoma saw more than 2,600 magnitude 3 or higher earthquakes. The USGS now says that Oklahoma has more earthquakes on a regular basis than California. And Casey, a postdoctoral researcher at University of California Berkeley, found that more earthquakes means more Google searches for anxiety, according to a recently published study in the journal of Environmental Epidemiology.
"It does appear that the population of Oklahoma is reacting to these earthquakes, and that might be something policy makers and others will want to take into account when deciding how to move forward with fracking in the state and how to move forward with the safe wastewater reinjection if they continue with the practice," she said.
Casey pulled monthly Google search data from January 2010 to May 2017, and looked for searches during the months where Oklahoma had a magnitude 4 or higher earthquake. Casey and co-authors found that anxiety-related Google searches increased by 1.3 percent in the month following an earthquake, and 5.8 percent if there was more than one earthquake in a month.
The researchers tracked the amount of Google searches for anxiety from 2010 to 2017 for the U.S., as well as just Oklahoma and found that while anxiety searches are increasing overall, there was a "significant divergence between United States and Oklahoma queries," according to the study.
Sidra Goldman-Mellor, co author and professor of public health at University of California, Merced, said that they were surprised with the results.
While Casey and colleagues limited the earthquakes to magnitude 4, which the U.S. Geological Survey describes as feeling like a heavy truck hitting a building, there have been multiple earthquakes below magnitude 4 in Oklahoma in June alone. According to the USGS earthquake data, there were three earthquakes in Oklahoma on June 19.
Gas and oil’s earthquake problem
Casey's research mostly looks at the health implications of fracking, which was what led her to Oklahoma, she said. In the state, wastewater from fracking, as well as oil production, is being re-injected into the land, which environmental researchers now believe cause earthquakes.
In 2014, Cornell Earth and Atmospheric Science Professor Katie Keranen published an article in Science linking the rise in Oklahoma earthquakes to wastewater injection, noting in the study she and her co-authors found that four of the most used wells were capable of inducing 20 percent of the earthquakes felt in the central United States from 2008 to 2013.
The Oklahoma government has acknowledged the increase in man-made earthquakes, noting on its website for earthquakes that while the state has had some seismic activity in its history, the rate of earthquakes can no longer be attributed to natural causes alone.
But the USGS said that most Oklahoma earthquakes are due to wastewater injection from oil extraction, not fracking wastewater, although some of the earthquakes have been linked to fracking.
Earthquakes’ psychological toll
Research has shown that anxiety is common after an earthquake, Goldman-Mellor said.
"I think it's very reasonable that lots of people are searching for anxiety. These days, most people, Google is the first thing people turn to when they are having some kind of problem, whether it is a health problem or any other kind of problem," she said.
Natural disasters cause anxiety because they are usually unpredictable and can be deadly, said Paul Greene, a professor of psychology at Iona College. They also have aftershocks.
During an earthquake, people's survival instinct takes over, he said. In the weeks after, they'll experience anxiety, with some cases turning to PTSD after months, he said. And those who experience multiple earthquakes will have a harder time
Casey and Goldman-Mellor pointed out that Oklahomans tend to be poorer than most of the country, which could make things worse.
The researchers noted that residents might have less access to healthcare—the United Health Foundation ranked Oklahoma as 43rd in the county for healthcare in 2017— and may live in buildings that are more susceptible to earthquake damage. Their financial status might also make it so they cannot leave the area as easily.
"Unfortunately, like many environmental exposures it's possible there's concerns about environmental justice with this exposure as well," Casey said.
The advantage and disadvantage of Google
The study was able to get close to measuring real-time mental health impacts using the Google search data, Casey said. Often, psychology studies are not able to use real-time data and are done in the months following an event.
But there were still some caveats: Google search does not mean someone has anxiety, so further research would be needed to get a better picture of the mental health of Oklahomans, Casey said.
Also, the researchers might not have captured all of the people experiencing anxiety, Casey said, because some Oklahomans don't have a computer or a way to access the internet.
So far the research on the mental health impacts of man-made earthquakes have been ignored, Casey said. It's challenging to do this type of research, especially with the shifts in energy sources, but she said she's hopeful that more studies will be conducted.
"I think as Americans become increasingly cognizant that mental health is just as important as physical health, new ways that we can actually track population-level mental health, potentially thought Google searches, and find exposures that might modulate mental health, like these Oklahoma earthquakes, are really important," she said.

Schools evacuated due to toxic gas. Smelly tap water at home. Tourist operators and fishers struggling to stay in business. Job losses. Power outages affecting tens of thousands of people at a time. Dangerous health problems. Even lives lost.
Such crises were some of the consequences of sargassum in the islands of the Caribbean in 2023, and they have become common in the region since 2011 when massive blooms began inundating the shorelines in the spring and summer months.
On April 18, 2023 in Guadeloupe, the air-quality monitoring agency Gwad’Air advised vulnerable people to leave some areas because of toxic levels of gas produced by sargassum. Six weeks later, about 600 miles to the northwest, sargassum blocked an intake pipe at an electricity plant at Punta Catalina in the Dominican Republic. One of the facility’s units was forced to temporarily shut down, and a 20-year-old diver named Elías Poling later drowned while trying to fix the problem.
CAMERON PARISH, La. — Late into the night, John Allaire watches the facility next to his home shoot 300-foot flares from stacks.
He lives within eyesight of southwest Louisiana’s salty shores, where, for decades, he’s witnessed nearly 200 feet of land between it and his property line disappear into the sea. Two-thirds of the land was rebuilt to aid the oil and gas industry’s LNG expansion. LNG — shorthand for liquified natural gas – is natural gas that's cooled to liquid form for easier storage or transport; it equates to 1/600th the volume of natural gas in a gaseous state. It’s used to generate electricity, or fuel stove tops and home heaters, and in industrial processes like manufacturing fertilizer.
In the U.S., at least 30 new LNG terminal facilities have been constructed or proposed since 2016, according to the
Oil and Gas Watch project. Louisiana and Texas’ Gulf Coast, where five facilities are already operating, will host roughly two-thirds of the new LNG terminals – meaning at least 22 Gulf Coast LNG facilities are currently under construction, were recently approved to break ground or are under further regulatory review.
Although the U.S. didn’t ship LNG until 2016, when a freight tanker left, a few miles from where Cameron Parish’s LNG plants are today, last year the country became the global leader in LNG production and export volume, leapfrogging exporters like Qatar and Australia. The
EIA’s most recent annual outlook estimated that between the current year and 2050, U.S. LNG exports will increase by 152%.
Allaire, 68, watches how saltwater collects where rainwater once fed the area’s diminishing coastal wetlands. “We still come down here with the kids and set out the fishing rods. It's not as nice as it used to be,” he told
Environmental Health News (EHN).
That intimacy with nature drew Allaire to the area when he purchased 311 acres in 1998. An environmental engineer and 30-year oil and gas industry veteran, he helped lead environmental assessments and manage clean-ups, and although retired, he still works part-time as an environmental consultant with major petroleum companies. With a lifetime of oil and gas industry expertise, he’s watched the industry's footprint spread across Louisiana and the Gulf of Mexico’s fragile shores and beyond. Now that the footprints are at the edge of his backyard, Allaire is among a cohort of organizers, residents and fisher-folk in the region mobilizing to stop LNG facility construction. For him, the industry’s expansion usurps the right-or-wrong ethics he carried across his consulting career. For anglers, oil and gas infrastructure has destroyed fishing grounds and prevented smaller vessels from accessing the seafood-rich waters of the Calcasieu River.
From the view of Allaire’s white pickup truck as he drives across his property to the ocean’s shore, he points to where a new LNG facility will replace marshlands. Commonwealth LNG intends to clear the land of trees and then backfill the remaining low-lying field.
“You see what’s happening with the environment,” Allaire said. “When the facts change, I got to change my mind about what we’re doing.”

During an Earth Day rally in April, community members gathered in the urban center of Lake Charles to demand local oil and gas industries help deliver a safer, healthier future for all. In between live acts by artists performing south Louisiana’s quintessential zydeco musical style, speakers like James Hiatt, a Calcasieu Parish native with ties to Cameron Parish and a Healthy Gulf organizer, and RISE St. James organizer Sharon Lavigne, who’s fighting against LNG development in rural Plaquemines Parish near the city of New Orleans, asked the nearly 100 in attendance to imagine a day in which the skyline isn’t dotted by oil and gas infrastructure.
Not long ago, it was hard to imagine an Earth Day rally in southwest Louisiana at all. For decades, the area has been decorated with fossil fuel infrastructure. Sunsets on some days are highlighted by the chemicals in the air; at night, thousands of facilities’ lights dot the dark sky.
“It takes a lot of balls for people to start speaking up,” Shreyas Vasudevan, a campaign researcher with the Louisiana Bucket Brigade, told EHN in the days after the rally. In a region with its history and economy intertwined with oil and gas production, “you can get a lot of social criticism – or ostracization, as well – even threats to your life.”
Many are involved in local, regional and national advocacy groups, including the Louisiana Bucket Brigade, Healthy Gulf, the Sierra Club, the Natural Resources Defense Council, the Turtle Island Restoration Network, the Center for Biological Diversity and the National Audubon Society.

But environmental organizers are fighting a multi-billion-dollar industry with federal and state winds at its back. And LNG’s federal support is coupled with existing state initiatives.
Under outgoing Louisiana Gov. John Bel Edwards — a term-limited Democrat — the state pledged a goal of reaching net-zero greenhouse emissions by 2050. Natural gas, which the LNG industry markets as a cleaner-burning alternative, is cited as one of the state’s solutions. Louisiana is the only state that produces a majority of its carbon emissions through fossil fuels refining industries, like LNG, rather than energy production or transportation. Governor Edwards’ office did not return EHN’s request for comment.
This accommodating attitude towards oil and gas industries has resulted in a workforce that’s trained to work in LNG refining facilities across much of the rural Gulf region, said Steven Miles, a lawyer at Baker Botts LLP and a fellow at the Baker Institute’s Center on Energy Studies. Simultaneously, anti-industrialization pushback is lacking. It’s good news for industries like LNG.
“The bad news,” Miles added. “[LNG facilities] are all being jammed in the same areas.”
One rallying cry for opponents is local health. The Environmental Integrity Project found that LNG export terminals emit chemicals like carbon monoxide –potentially deadly– and sulfur dioxide, of which the American Lung Association says long-term exposure can lead to heart disease, cancer, and damage to internal or female reproductive organs.
An analysis of emissions monitoring reports by the advocacy group the Louisiana Bucket Brigade found that Venture Global’s existing Calcasieu Pass facility had more than 2,000 permit violations.That includes exceeding the permit’s authorized air emissions limit to release nitrogen oxides, carbon monoxide, particulate matter and volatile organic compounds 286 out of its first 343 days of operation.
The Marvel Crane, the first liquid natural gas carrier to transport natural gas from the Southwest Louisiana LNG facility, transits a channel in Hackberry, Louisiana, May 28, 2019.
“This is just one facility,” at a time when three more facilities have been proposed in the region and state, Vasudevan said. Venture Global’s operational LNG facility — also known as Calcasieu Pass — “is much smaller than the other facility they’ve proposed.”
In an area that experienced 18 feet of storm surge during Hurricane Laura in 2020 — and just weeks later, struck by Hurricane Delta — Venture Global is planning to build a second export terminal Known as “CP2,” it’s the largest of the roughly two dozen proposed Gulf LNG export terminals, and a key focal point for the region’s local organizing effort.
Residents “don’t really want LNG as much as they want Cameron [Parish] from 1990 back,” Hiatt told EHN of locals’ nostalgia for a community before storms like Rita in 2005 brought up to 15 feet of storm surge, only for Laura to repeat the damage in 2020. Throughout that time, the parish’s population dipped from roughly 10,000 to 5,000. “But the wolf knocking at the door is LNG. Folks in Cameron think that's going to bring back community, bring back the schools, bring back this time before we had all these storms — when Cameron was pretty prosperous.”
“Clearly,” for the oil and gas industry, “the idea is to transform what was once the center of commercial fishing in Louisiana to gas exports,” Cindy Robertson, an environmental activist in southwest Louisiana, told EHN.
Helping fishers’ impacted by LNG is about “actual survival of this unique culture,” Cooke said.
In a measure of organizers’ success, she pointed to a recent permit hearing for Venture Global’s CP2 proposal. Regionally, it’s the only project that’s received an environmental permit, but not its export permit, which remains under federal review. At the meeting, some spoke on the company’s behalf. As an organizer, it was a moment of clarity, Cooke explained. Venture Global officials “had obviously done a lot of coaching and organizing and getting people together in Cameron to speak out on their behalf,” Cooke said. “So, in a way, that was bad. But in another way, it shows that we really had an impact.”
“It also shows that we have a lot to do,” Cooke added.
Environmental organizers like Alyssa Portaro describe a sense of fortitude among activists — she and her husband to the region’s nearby town of Vinton near the Texas-Louisiana border. Since the families’ relocation to their farm, Portaro has worked with Cameron Parish fisher-folk.
“I’ve not witnessed ‘community’ anywhere like there is in Louisiana,” Portaro told EHN. But a New Jersey native, she understands the toll environmental pollution has on low-income communities. “This environment, it’s so at risk — and it’s currently getting sacrificed to big industries.”
“People don’t know what we’d do without oil and gas. It comes at a big price,” she added.
Southwest Louisiana’s Cameron Parish is one of the state’s most rural localities. Marine economies were the area’s economic drivers until natural disasters and LNG facilities began pushing locals out, commercial fishers claim.

A disappearing parish
The stakes are seemingly higher for a region like southwest Louisiana, which is the epicenter of climate change impacts.
In nearly a century, the state has lost roughly 2,000 square miles of land to coastal erosion. In part driving the state’s erosion crisis is the compounding impacts of Mississippi River infrastructure and oil and gas industry activity, such as dredging canals for shipping purposes, according to a March study published in the journal Nature Sustainability. Louisiana’s Coastal Protection and Restoration Authority said Cameron Parish could lose more land than other coastal parishes over the next 50 years. A recent Climate Central report says the parish will be underwater within that time frame.
On top of erosion and sea level rise impacts, in August, 2023, marshland across southwest Louisiana’s Cameron Parish burned. The fires were among at least 600 across the Bayou State this year. Statewide, roughly 60,000 acres burned — a more than six-fold increase of the state’s average acres burned per year in the past decade alone.
But while the blaze avoided coastal Louisiana communities like Cameron Parish, the fires represented a warning coming from a growing chorus of locals across the region — one that’s echoes by the local commercial fishing population, who claimed to have experienced unusually low yields during the same time, according to a statement from a local environmental group. At the site of the Cameron Parish fires are locations for two proposed LNG expansion projects.
"The idea is to transform what was once the center of commercial fishing in Louisiana to gas exports.” - Cindy Robertson, an environmental activist in southwest Louisiana
It was an unusual occurrence for an area that’s more often itself underwater this time of year due to a storm surge from powerful storms. For LNG expansion’s local opposition, it was a red flag.
As the Louisiana Bucket Brigade has noted prior, the confluence of climate change’s raising of sea levels and the construction of LNG export terminals — some are proposed at the size of nearly 700 football fields — are wiping away the marshland folks like Allaire watched wither. Among their fears is that the future facilities won’t be able to withstand the power of another storm like Laura and its storm surge, which wiped away entire communities in 2020.
Amidst these regional climate impacts, LNG infrastructure has shown potential to exacerbate the accumulation of greenhouse gasses that cause global warming. For the most part, LNG is made up of methane — a greenhouse gas that’s more than 80 times more potent than carbon dioxide in the atmosphere. Among the 22 current LNG facility proposals, the advocacy group Sierra Club described a combined climate pollution output that would roughly equal to that of about 440 coal plants.
The climate impacts prompt some of the LNG industry’s uncertainty going forward. It isn’t clear if Asian countries, key importers of U.S. LNG, will “embrace these energy transition issues,” said David Dismuke, an energy consultant and the former executive director of Louisiana State University’s Center for Energy Studies. Likewise, European nations remain skeptical of embracing LNG as a future staple fuel source.
“They really don't want to have to pull the trigger,” Dismukes added, referring to Europe’s hesitation to commit more resources to exporting LNG from the American market. “They don't want to go down that road.”
While there will be a tapering down of natural gas supply, Miles explained, “we’re going to need natural gas for a long time,” as larger battery storage for renewables is still unavailable.
“I'm not one of these futurists that can tell you where we're going to be, but I just don't see everything being extreme,” Dismukes said. “I don't see what we've already built getting stranded and going away, either.”
For now, LNG seems here to stay. From 2012 to 2022,U.S. natural gas demand — the sum of both domestic consumption and gross exports — rose by a whopping 43%, reported the U.S. Energy Information Administration, or EIA. Meanwhile, in oil and gas hotbeds like Louisiana and Texas, natural gas demand grew by 116%.
Throughout 25 years, Allaire has witnessed southwest Louisiana’s land slowly fade, in part driven by the same industrial spread regionally. Near where the front door of his travel trailer sits underneath the aluminum awning, he points to a chenier ridge located near the end of the property. It’s disappearing, he said.
“See the sand washing over, in here?” Allaire says, as he points towards the stretches of his property. “This pond used to go down for a half mile. This is all that's left of it on this side.”
HOUSTON — This week EHN is publishing letters from eighth grade students at YES Prep Northbrook Middle School in the Houston-area neighborhood of Spring Branch, Texas.
English educators Cassandra Harper and Yvette Howard incorporated the environment into a series of lessons in December last year. Each student conducted their own research to begin drafting letters to EHN about their concerns or hopes. EHN reporter Cami Ferrell visited their classrooms to share information about her personal reporting experiences in Houston.
The collection of letters, some of which were lightly edited, do not represent the opinions of YES Prep Northbrook or EHN, but are offered here as a peek into the minds of children and their relationship with environmental issues. You can see the first set of letters here.
Escuelas desalojadas debido a gases tóxicos. El agua potable de las casas con mal olor. Los operadores turísticos y los pescadores en lucha por mantener sus negocios. Pérdidas de empleos. Cortes de electricidad que afectan a decenas de miles de personas a la vez. Graves problemas de salud. Y pérdida de vidas.
Estas fueron algunas de las consecuencias que dejó el sargazo en las islas del Caribe en 2023, y que se han vuelto comunes en la región desde 2011, cuando la proliferación masiva de esas algas comenzó a arropar las costas durante los meses de primavera y verano.
El 18 de abril de 2023, en Guadalupe, la agencia de monitoreo de la calidad del aire Gwad’Air aconsejó a las personas vulnerables a que abandonaran algunas zonas debido a los niveles tóxicos de gas producido por el sargazo. Seis semanas después, a unas 600 millas al noroeste, el sargazo bloqueó una tubería en una planta eléctrica en Punta Catalina, República Dominicana. Una de las unidades de la instalación se vio obligada a cerrar temporalmente. Allí, Elías Poling, un buzo de 20 años de edad, se ahogó mientras intentaba solucionar el problema.
The Northern Arapaho Tribe and the city of Cheyenne are applying for federal grants to fund clean energy projects, despite Wyoming's governor declining to participate.
The Northern Arapaho Tribe and City of Cheyenne are pursuing millions in federal funds for solar power and other green initiatives.
Cheyenne aims to build solar farms and upgrade wastewater plants, while the Northern Arapaho focus on a solar micro-grid, energy-efficient housing and change the tribe's fleet to electric and hybrid vehicles.
Both see these projects as key to creating jobs and reducing utility costs in Wyoming's challenging economic and environmental landscape.
Key quote:
“There’s a lot of interest in solar here. People are pretty interested in being more self-sufficient with the utilities.”
— Steve Babits, environmental scientist with the Northern Arapaho Natural Resource Office.
Why this matters:
Many indigenous communities face disproportionate energy challenges, including reliance on fossil fuels, lack of access to reliable electricity and environmental degradation due to extractive industries. By investing in clean energy initiatives such as solar, wind, or hydroelectric power, tribes aim to reduce their dependence on non-renewable resources, lower energy costs, and mitigate environmental impacts on their lands.
North Dakota, the nation's third largest oil producer launched a preliminary climate plan.
The plan prioritizes tree planting, agricultural improvements and energy efficiency enhancements.
Critics argue the plan avoids addressing significant emissions from the oil, gas, and coal industries.
Future phases promise to tackle more challenging projects.
Key quote:
"There’s a big blind spot in that plan. They’re ignoring the fact that they have a highly emitting oil and gas and coal industry."
— Scott Skokos, Dakota Resource Council.
Why this matters:
Transitioning away from fossil fuels can pose economic challenges for regions like North Dakota that are heavily reliant on industries like coal mining or oil extraction.
Europe's average temperatures have risen to 2.3 degrees Celsius above pre-industrial levels, almost double the global increase.
Extreme weather, including heatwaves and floods, caused significant economic losses and human fatalities across Europe last year.
The economic losses of weather and climate events were estimated at more than 13.4 billion euros (about $14.3 billion) in 2023.
Key quote:
"Europe saw yet another year of increasing temperatures and intensifying climate extremes — including heat stress with record temperatures, wildfires, heat waves, glacier ice loss and lack of snowfall."
— Elisabeth Hamdouch, deputy head of unit for Copernicus at the EU’s Executive Commission.
Why this matters:
Scientists predict that if global temperatures continue to rise, Europe will see and increase in climate-related economic loss and negative health outcomes, like deaths linked to extreme heat and wildfires, droughts and flooding.
Last yearEHN spoke with heat equity experts about how young people can work toward protecting the most vulnerable from extreme heat and advancing climate justice.
Biodegradable food packaging is a step in the right direction, experts say, but when composted carries risks of microplastic and chemical contamination.
