A slow-motion section of the San Andreas fault may not be so harmless after all

The central section of the great fault spanning California, thought to be creeping along harmlessly at the moment, has experienced big quakes in the past, says a new study.

Hidden weaknesses within volcanoes may cause volcano collapse

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

Discovery of ancient underwater landslide could help Middle Eastern nations realize tsunami hazards

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.

New model may improve San Francisco Bay Area, U.S., seismic hazard maps

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

Factors that shaped the massive Cauca River Canyon in the tropical Andes

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

Secondary cratering on Earth: The Wyoming impact crater field

Several dozen small impact craters, 10–70-m in size, have been discovered in southeastern Wyoming. A team of U.S. and German geoscientists found these ancient craters in exposed sedimentary layers from the Permian period (280 million years ago). After discovering the first craters, the team initially suspected that they are a crater-strewn field, formed by the Secondary cratering on Earth: The Wyoming impact crater field

Mineral dating reveals new clues about important tectonic process

Ancient rocks on the coast of Oman that were once driven deep down toward Earth’s mantle may reveal new insights into subduction, an important tectonic process that fuels volcanoes and creates continents, according to a new study.
