Seismogram

Strange seismic wave arrivals from a 2010 earthquake under Spain were the clues that led to an unexpected discovery beneath the western Mediterranean: a subducted oceanic slab that has completely overturned.

The massive marsquake, detected on Dec. 24, 2021, was caused by a Martian impact.

In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.

A new study of decades worth of seismogram data shows that the surface of Earth's iron and nickel core is more malleable than scientists thought.

For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds.

An artificial intelligence approach borrowed from natural language processing—much like language translation and autofill for text on your smart phone—can predict future fault friction and the next failure time with high resolution in laboratory earthquakes. The technique, applying AI to the fault's acoustic signals, advances previous work and goes beyond by predicting aspects of the future state of the fault's…

Jeffrey Marlow writes about how undersea fibre-optic Internet cables, including those owned by Google, can detect earthquakes and may warn of tsunamis.

Fans inside and outside Tiger Stadium erupted with excitement as they watched their team beat Alabama in overtime. At the same time, a seismometer on LSU's campus captured the excitement, recording two distinctive seismic wave events. The first came at 10:03 p.m. after LSU football quarterback Jayden Daniels scored a touchdown from a 25-yard run. The second event came just minutes later at 10:06 when Mason Taylor…

A moderate earthquake shook Italy's northeastern coast early Wednesday, causing some cracks in buildings and prompting at least one health clinic to evacuate. There were no immediate reports of injuries.

NASA's InSight lander recorded a magnitude 4 marsquake last Dec. 24, but scientists learned only later the cause of that quake: a meteoroid strike estimated to be one of the biggest seen on Mars since NASA began exploring the cosmos. What's more, the meteoroid excavated boulder-size chunks of ice buried closer to the Martian equator than ever found before—a discovery with implications for NASA's future plans to…

A magntitude-5.1 earthquake struck Friday on Hawaii's Mauna Loa, the largest active volcano on the planet that scientists say is in a "state of heightened unrest."

Using a method that works backward from a set of observed earthquakes to test seismic models that fit those observations, researchers working in the Delaware Basin were able to determine whether earthquakes in the region since 2017 were caused by oil and gas operations.
