Lava domes form at the top of many volcanoes when viscous lava erupts. When they become unstable, they can collapse and cause a hazard. An international team of researchers has analyzed summit dome instabilities at Merapi Volcano, Indonesia. The researchers hope that by understanding the inner processes, volcano collapses can be better forecasted. Title: Hidden … Hidden weaknesses within volcanoes may cause volcano collapse

An earth scientist has discovered evidence of an ancient underwater landslide and associated tsunami in the Gulf of Aqaba, a subsidiary of the Red Sea, that should serve as a warning for many nations in the Middle East.

Using the Santa Cruz Mountains as a natural laboratory, researchers have built a 3D tectonic model that clarifies the link between earthquakes and mountain building along the San Andreas fault for the first time. The findings may be used to improve seismic hazard maps of the Bay Area. Title: New model may improve San Francisco … New model may improve San Francisco Bay Area, U.S., seismic hazard maps

In July 2019, a series of earthquakes including two major shocks of magnitude 6.4 and 7.1 a day apart struck near Ridgecrest, CA, between Los Angeles and Las Vegas. For local residents, it was a violent interruption to the Fourth of July holiday. For seismologists, it was a rare opportunity to study how earthquakes damage … Ridgecrest shows how earthquakes damage Earth’s crust

A team of researchers recently embarked on a research expedition to the Tropical Andes of Colombia to study the massive Cauca River canyon. The team’s objective was to determine the age of formation of the Cauca River canyon and then compare that with known tectonic and climatic processes that happened in the region during the … Factors that shaped the massive Cauca River Canyon in the tropical Andes
