It’s Not Always About “The Big One”: Why We Mine for the Little Ones, Too
What’s a bit new, trendy, and even a little quirky in earthquake science? Mining through extensive earthquake data in clever, innovative ways – especially in search of the "little ones" we never feel...

A Milestone for Forecasting Earthquake Hazards
Simulating nearly 500,000 years of California earthquakes on a supercomputer, researchers were able to match hazard estimates from the state’s leading statistical model based on a hundred years of...

A Seismic Change in Predicting How Earthquakes Will Shake Tall Buildings
In their quest to make tall buildings safe during earthquakes, engineers have for decades relied on calculations that represent the tremors and convulsions that a building can endure. Some of the...
