Years before the devastating Tohoku earthquake struck the coast of Japan in 2011, the Earth's crust near the site of the quake was starting to stir. Researchers are using computer models to investigate if tiny tremors detected near this site could be connected to the disaster itself.
Researchers argue in a new study that a paradigm shift is needed for assessing bridges' tsunami risk.
Using data gleaned from historical reports, researchers have now identified the sources of some of the most destructive Indonesian earthquakes in Java, Bali and Nusa Tenggara, using these data to independently test how well Indonesia's 2010 and 2017 seismic hazard assessments perform in predicting damaging ground motion.
Earthquake hazard assessment often overlooks intra-slab earthquakes. EarthScope Transportable Array data for the 2016 Iniskin and Nov. 30, 2018 Anchorage earthquakes in Alaska offer new insight into potential causes of heavy shaking from these intra-slab events.
Researchers have observed foreshocks that, if analyzed accordingly and in real-time, may possibly increase the early-warning time before a large earthquake from just a few seconds up to several hours.
Last September's magnitude 8.2 Tehuantepec earthquake happened deep, rupturing both mantle and crust, on the landward side of major subduction zone in the Pacific Ocean off Mexico's far south coast. It's unanticipated location suggests a potential new threat for Central America's coastline.
Researchers have applied machine-learning techniques to achieve fast, accurate estimates of local geomagnetic fields using data taken at multiple observation points, potentially allowing detection of changes caused by earthquakes and tsunamis. A deep neural network (DNN) model was developed and trained using existing data; the result is a fast, efficient method for estimating magnetic fields for unprecedentedly early detection of natural disasters. This is vital for developing effective warning systems that might help reduce casualties and widespread damage.
The southeast flank of Mount Etna slowly slides towards the sea. A team of scientists showed for the first time movement of Etna's underwater flank using a new, sound-based geodetic monitoring network. A sudden and rapid descent of the entire slope could lead to a tsunami with disastrous effects for the entire region.
