Latest Yellowstone Caldera Stories
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.
As many as 30 earthquakes were recorded in California over the past 24 hours, most of which were less than a magnitude in intensity. Despite all the tremors regional seismometers pick up in California and Nevada -- 808 in the past week alone -- most go unnoticed by residents.
A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week.
Geologists from Brigham Young University in Utah have found evidence of a massive supervolcano near the Utah-Nevada border that had a massive eruption around 30 million years ago. It was 5,000 times larger than the Mount St. Helens eruption in 1980.
Volcanism in the Yellowstone region was caused by the defunct pieces of a former mantle plume that were severely deformed. Circulation currents, driven by the movement of tectonic plates at the Cascades subduction zone, also affected the plume.
The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and 2005.
New research is casting doubts on the frequency or even the possibility of a ‘super-eruption’ that could blot out the sun from the Earth with a thick veil of volcanic ash.
Supervolcanoes are one of nature's most destructive forces.
NASA said on Tuesday that there is no evidence of a massive supervolcano erupting in 2012, despite what some may believe.
The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions.
Yellowstone National Park is located in the United States. The majority of the park is located in Wyoming, but there are smaller areas of the park in Idaho and Montana. It is thought that this area was the first to be established as a national park in the entire world. The area was home to Native Americans for about 11,000 years, but was not well known to Americans until the 1860’s, when the first organized explorations were conducted there. The Lewis and Clark Expedition in the 19th...
