The greater Los Angeles area has long been the subject of intense seismographic monitoring. A network of highly sensitive ...

Now, researchers have connected 49 seismic events to impact craters, proving that meteorite strikes leave distinct seismic ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth ...

Despite record rainfall in the region in early 2023, only a fraction of Southern California’s groundwater reserves has been replenished, researchers report. Their study, which leverages seismic noise ...

Researchers at Stanford University developed a new method to measure water levels in the state’s aquifers using readily available seismic data.

Scientists using seismic data tracked groundwater levels beneath the L.A. area. They found heavy rains in 2023 boosted ...

In land seismic, the methods for generating seismic waves in the substrate are rather simple. Dynamite and a process called vibroseis (high-frequency replication) are the most practical and common.

Professor Ritzwoller is an observational seismologist. His early work was mainly in normal mode seismology and helioseismology. Research in the last decade has concentrated on developing methods to ...
