Natural arches hum their health and scientists are listening

For the first time, scientists have found a way to detect if the breathtaking natural arches of Utah's Canyonlands and Arches national parks are suffering from internal damage that could lead to their collapse, according to a new study in Geophysical Research Letters.

16th century Italian earthquake changed river's course

In 1570, a 5.8-magnitude earthquake struck the northern Italian city of Ferrara, causing dozens of deaths, major damage to the city and thousands to flee. A new study in Journal of Geophysical Research: Solid Earth finds that the 16th century earthquake and subsequent aftershocks were the last step in a tectonic process that occurred over thousands of years and changed the course of the Po River.
