16 May 2018–The 2004 Indian Ocean tsunami has researchers reevaluating whether a magnitude 9.0 megathrust earthquake and resulting tsunami might also be a likely risk for the Caribbean region, seismologists reported at the SSA 2018 Annual Meeting. “Before 2004, we thought an earthquake of about 8.0 was about right for … Continue Reading »

16 May 2018–There are more than a million kilometers of underwater telecommunication cables lining the world’s ocean floor. Scientists would like to outfit those cables with environmental sensors—including seismometers—to improve the speed and success of tsunami warnings and to create better models of the Earth’s interior. At the 2018 SSA … Continue Reading »

15 May 2018–Nyiragongo in the Democratic Republic of the Congo is among the world’s most active volcanoes, with a persistent lava lake as one of its defining features. In a talk at the 2018 SSA Annual Meeting, Adrien Oth of the European Center for Geodynamics and Seismology discussed how he … Continue Reading »

15 May 2018–Record cold temperatures during the winter of 2014 in the Midwestern United States froze large parts of the Great Lakes—and inadvertently offered seismologists a chance to learn more about the seismic signals created by the lakes’ wind-driven waves. The deep freeze stilled the waves and created a period … Continue Reading »
