Ten years ago Wednesday, Mount St. Helens in Washington erupted after being quiet for nearly two decades, and now US Geological Survey (USGS) scientists are concerned that the volcano could mark the occasion by becoming active once again.
A new study from the United States Geological Survey (USGS) suggests that the ash cloud from a Yellowstone supereruption would blanket the Rocky Mountains several meters deep, and it would deposit at least millimeters of ash at least as far away as New York, Los Angeles and Miami.
In August of last year, Jupiter's moon Io surprised astronomers with three massive volcanic eruptions within a two-week period. Two studies, accepted for publication in the journal Icarus, suggest that these volcanic "outbursts" might occur more commonly than previously thought.
One of the world’s most active volcanoes showed its ugly side this weekend, erupting and producing an ash cloud that spread out across one southern Japanese city.
Authorities in Mexico have raised the alert level for towns in two central states and the capital after an increased amount of explosive activity has occurred at Popocatepetl volcano, Mexico’s second highest peak at 17,900 feet.
Recognizing well-established patterns of pre-eruption unrest in monitoring data is vital in volcanic eruption forecasting. To develop better monitoring procedures, however, understanding volcanic eruptions that deviate from these patterns is crucial as well.
One of Iceland’s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak.
Eldfell is an active stratovolcano that is located in Iceland on the island of Heimaey, in the Vestmannaeyjar archipelago. It reaches an elevation of 656 feet and was created during a volcanic eruption on the east side of the island in 1973. Its name means Mountain of Fire in the Icelandic language. Iceland is an area with a high frequency of volcanic activity because it is located on top of the Iceland hotspot and beside the Mid-Atlantic Ridge. So many eruptions occur here that it is thought...
Volcanology is the study of volcanoes, magma, lava, and related geological, geochemical, and geophysical phenomena. The term volcanology comes from the Latin word Vulcan. Vulcan is the ancient Roman god of fire. A volcanologist is a person who studies the creation of volcanoes, and their current and historic eruptions.
