[Leer en español] 15 May 2018–New seismic hazard and risk models developed for South America suggest that more than 160 million people—about one-third of the continent’s total population—live in areas with significantly elevated seismic hazard, according to a report discussed at the 2018 SSA Annual Meeting. Risk is greatest in … Continue Reading »
17 April 2018–For centuries people have claimed that strange behavior by their cats, dogs and even cows can predict an imminent earthquake, but the first rigorous analysis of the phenomenon concludes that there is no strong evidence behind the claim. The paper published in the Bulletin of the Seismological Society … Continue Reading »
27 March 2018–Hours after the 2016 Kaikoura earthquake hit New Zealand, researchers were able to share information with first responders about where significant landsliding might have occurred to block roads and rivers, according to a new report in the Bulletin of the Seismological Society of America. The modeling approach used … Continue Reading »
20 February 2018–Wastewater created during oil and gas production and disposed of by deep injection into underlying rock layers is the probable cause for a surge in earthquakes in southern Kansas since 2013, a new report in the Bulletin of the Seismological Society of America concludes. Until 2013, earthquakes were … Continue Reading »
29 November 2017— Although magnitude 6 earthquakes occur about every 25 years along the Parkfield Segment of the San Andreas Fault, geophysical data suggest that the seismic slip induced by those magnitude 6 earthquakes alone does not match the long-term slip rates on this part of the San Andreas fault, … Continue Reading »
A comprehensive study of faults along the north side of the Olympic Mountains of Washington State emphasizes the substantial seismic hazard to the northern Puget Lowland region. The BSSA study examined the Lake Creek-Boundary Creek and Sadie Creek faults along the north flank the Olympic Mountains. … Continue Reading »
