Red tape and regulations have made it difficult for volcanologists to build monitoring stations along Mount Hood and other active volcanoes. The article shares where US active volcanoes are located and includes coloful images.
A series of erathquakes in early July 2019 ruptured an shifted the surface of the Mojave Desert. This short USGS video shows the movement with Landsat 8 and Sentinel-2B images.
This StoryMap was designed by the Minnesota Geological Survey for K12 education on Minnesota's geology. It can be used for all to access geological information as well as GIS content to that information.
A 2018 study suggests the mantle will cool to such an extent that the plates will grind to a halt in 1.45 billion years--changing life on Earth as we know it.
Berkely student William Hawley suggests that the there might be a tear in the Juan de Fuca tectonic plate in a recent study.
After tens of millions of years slowly slipping under the western margin of North America, the Juan de Fuca tectonic plate is nearing the end of its existence. Scientists watching its last days have found a tiny tear deep below central Oregon where the plate is ripping apart, offering clues as to how a dying plate twists and deforms as it is swallowed up by a continent. Ultimately, the tear might be the cause of recent earthquakes off the American coast and a string of volcanoes that stretches across Oregon.
