27 June 2022–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. The new study published … Continue Reading »
Bon Voyage! It’s Global Travel Grant Application Time Throughout July, student and early-career members are invited to apply for the next round of SSA Global Travel Grants.

16 May 2022–Peggy Hellweg was the first Explainer hired at the Exploratorium, a science, technology and arts museum in San Francisco, when it opened in 1969. The job as a young docent, engaging visitors and leading demonstrations, was a perfect fit for Hellweg. She had grown up in a family … Continue Reading »
3 May 2022–Including topography—the hills, cliffs and valleys of a landscape—in ground motion models shows where shaking might be most amplified during an earthquake, researchers demonstrate with detailed new models of the Puget Sound region. In their models, Ian Stone of the U.S. Geological Survey and colleagues simulated several magnitude … Continue Reading »
22 April 2022–The presence of an atmospheric acoustic duct, a channel of sound at the boundary between the troposphere and stratosphere, has been verified for the first time by Sandia National Laboratory scientists. Solar hot air balloons carrying microbarometers floating in the lower stratosphere were able to observe infrasound signals … Continue Reading »
