New map reveals nearly half of the US faces landslide risk

Government scientists have released new data showing that 44% of the U.S. is at risk of experiencing landslides, with some areas particularly vulnerable.

Austyn Gaffney reports for The New York Times.

In short:

A new interactive map from the U.S. Geological Survey identifies nearly 44% of the U.S. as susceptible to landslides.
High-risk areas include Appalachia, the Rocky Mountains, the California coast, southeast Alaska and Puerto Rico, where more than 90% of the territory is at risk.
Landslides are often triggered by heavy rain and human development, with climate change increasing the likelihood of intense rainfall events.

Key quote:

“The best protection is knowledge. Knowing what a landslide is and how it might impact you is the best first step toward preparation.”

— Benjamin Mirus, research geologist with the United States Geological Survey

Why this matters:

Landslides pose a significant hazard, especially as climate change increases extreme rainfall, which is a primary trigger. Understanding landslide risks helps communities prepare and reduce the potential for devastating loss of life and property.
