15 May 2018–Scientists monitoring the vibrations of natural rock arches have found that the resonant frequencies of arches undergo dynamic changes from day to day, according to research presented at the 2018 SSA Annual Meeting. University of Utah doctoral student Paul Geimer and colleagues are analyzing these frequency changes to … Continue Reading »
15 May 2018–Almost 70 years later, the man remembers the August day in Playa Rincon, when he clung to the top of an almond tree to survive a tsunami where the waters rushed about 700 meters inland after a magnitude 8.1 earthquake. His recollections and other astonishing eyewitness accounts of … Continue Reading »
11 May 2018–How big is an earthquake? Seismologists have been measuring this feature—the magnitude of an earthquake—for more than a century, but the answers are not always as straightforward as one would think, says Allison Bent, a research seismologist with Natural Resources Canada. Numbers associated with the Richter scale and … Continue Reading »
2 May 2018–Researchers reexamining historical seismograms from the 1906 Meishan earthquake have uncovered a new mechanism for the quake, one of the deadliest to ever strike Taiwan. The new mechanism provides a better fit for the fault rupture expected for the magnitude 7.1. earthquake, as well as for the distribution … 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 »
11 April 2018–In 1994, Natalia Ruppert arrived at the University of Alaska Fairbanks to start graduate school, uncertain whether she would stay for more than one semester. Now, Ruppert has been studying earthquakes in her adopted state and country for almost 25 years, with no plans to leave Fairbanks in … Continue Reading »
