Simulations of the historical quake raise new concerns: A similar event in the future could cause a devastating tsunami in Chile’s most populated coastal region.Read More »Geochemistry, Mineralogy, Volcanology
A widely used technique to monitor sulfur dioxide was tweaked to focus on water vapor at Peru’s Sabancaya Volcano. Results show that the volcano steamed up prior to its 2016 eruption.Read More »Geology & Geophysics
To understand the ancient movement of Earth’s tectonic plates, comprehensive magnetic and petrographic studies are needed to detect secondary magnetization in carbonates and other sedimentary rocks.Read More »Geochemistry, Mineralogy, Volcanology
Experimental studies of frictional weakening beneath a deadly rock avalanche in China help to clarify the mechanisms that cause these devastating natural disasters.Read More »Geochemistry, Mineralogy, Volcanology
Researchers have developed a new numerical model that can, for the first time, solve for both the speed and the path of a propagating dike.Read More »Geology & Geophysics
Analysis of the change in the stratovolcano's tilt just prior to the explosion suggests that the cracking of a previously intact fluid barrier caused the country's deadliest eruption since 1926.Read More »Geochemistry, Mineralogy, Volcanology
