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.
Researchers have developed a new way to model seismic risk, which they hope will better inform disaster risk reduction planning in earthquake-prone areas.
The threat of rising sea levels to coastal cities and communities throughout the world is well known, but new findings show the likely increase of flooding farther inland from tsunamis following earthquakes.
