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.

Small rivers could have big impact on Arctic Ocean

The Mackenzie River carries the bulk of freshwater flow from North America's tundra to the North Atlantic. But what about the effects of smaller rivers from Canada's Arctic islands?
