FAQs

Can you predict earthquakes?

No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future. USGS scientists can only calculate the probability that a significant earthquake will occur (shown on our hazard mapping) in a specific area within a certain number of years. An earthquake prediction must define 3 elements: 1...

Can animals predict earthquakes?

The earliest reference we have to unusual animal behavior prior to a significant earthquake is from Greece in 373 BC. Rats, weasels, snakes, and centipedes reportedly left their homes and headed for safety several days before a destructive earthquake. Anecdotal evidence abounds of animals, fish, birds, reptiles, and insects exhibiting strange behavior anywhere from weeks to seconds before an...

Why are we having so many earthquakes? Has naturally occurring earthquake activity been increasing? Does this mean a big one is going to hit? OR We haven't had any earthquakes in a long time; does this mean that the pressure is building up for a big one?

A temporary increase or decrease in seismicity is part of the normal fluctuation of earthquake rates. Neither an increase nor decrease worldwide is a positive indication that a large earthquake is imminent. The ComCat earthquake catalog contains an increasing number of earthquakes in recent years--not because there are more earthquakes, but because there are more seismic instruments and they are...

Polar Bear Maternal Den Activity with the USGS Alaska Science Center: Middle School Lesson

Participate in this fun, interactive lesson that allows students to think like a wildlife biologist! This middle and high school lesson focuses on how changes in sea ice extent are leading to shifts in location and distribution of polar bear maternal dens in northern Alaska. Additionally, students can learn how to measure distances between dens and industrial sites.

Goose Nesting Camera Activity with the USGS Alaska Science Center: Middle School Lesson

Participate in this fun, interactive lesson that allows students to think like a USGS Wildlife Biologist! This lesson explores how disturbances in the natural environment could impact the nesting habits of geese in the wild. In this activity, students analyze camera shots of different nests and evaluate how the length of incubation breaks taken by geese can vary due to local disturbances.
