The National Volcano Early Warning System (NVEWS) will help USGS better monitor nation’s most dangerous volcanoes

In September 2004, USGS scientists detected sudden, but unmistakable, signs that Mount St. Helens was waking up. Volcano monitors had picked up the occurrence of hundreds of small earthquakes and other signals that the volcano’s crater floor had begun to rise. Within a week, several eruptions blasted clouds of ash into the atmosphere, and soon after, a new lava dome emerged in the crater.

Steamboat Counter

Steamboat Geyser, in the Norris Geyser Basin, is in a phase of more frequent water eruptions, much like in the 1960s and early 1980s. Although these eruptions do not have any implications for future volcanic activity at Yellowstone (after all, geysers are supposed to erupt, and most are erratic, like Steamboat), they are nonetheless spectacular.
