Explosion, Collapse, Earthquakes: Analysis of North Korea’s 2017 Nuclear Test

26 September 2018–The epicenter of the 3 September 2017 nuclear test explosion in North Korea occurred about 3.6 kilometers northwest of the country’s first nuclear test in October 2006, according to a new high-precision analysis of the explosion and its aftermath. The study published in Seismological Research Letters by Lian-Feng Zhao … Continue Reading »

Seasonal Reservoir Filling in India Deforms Rock, May Trigger Earthquakes

25 September 2018–The seasonal filling and emptying of reservoirs in India can cause measurable deformation of the surrounding rock, reducing the strength of nearby faults and potentially triggering earthquakes, according to two new papers published in the Bulletin of the Seismological Society of America. Researchers in India used global positioning … Continue Reading »

How Often Do Cascadia’s Megaquakes Occur?

16 May 2018–Devastating magnitude 8.0 to 9.0 megathrust earthquakes and accompanying tsunamis appear to have hit the U.S. Pacific Northwest and Southwest Canada about every 500 years on average. But some scientists think the recurrence interval between some of these large earthquakes may be shorter—along the lines of every 300 … Continue Reading »

How Big Can a Tsunami Be in the Caribbean?

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 »

At Work: Phoebe DeVries

Gaining insight into where earthquake aftershocks might occur is a long-standing challenge in earthquake science, especially as some aftershocks can approach the size of the mainshock earthquake and can damage buildings and roads already weakened by the main earthquake. Phoebe Robinson DeVries and her coauthors are pursuing one way to … Continue Reading »
