Is Yellowstone "due" for an eruption? Media reports have often claimed that Yellowstone is due to erupt. They claim that because the last eruption of the supervolcano was 70,000 years ago, it's bound to blow soon. But that's not how volcanoes work. "This is perhaps the most common mis...
rather than producing just new magma, " he says. "Either the crust under Yellowstone is turning into hard-to-melt basalt, or because the movement of North American plate has changed the magma pluming system away from Yellowstone
The last major eruption at Yellowstone was 1,000 times more powerful than the 1980 eruption of Mount St. Helens. If Yellowstone were to erupt in a supervolcanic event, the immediate effects would devastate the surrounding region, but the global impact would come from ash fall and changes in ...
Yellowstone may have the biggest concentration of geysers on the planet, but one has managed to stand out from the rest to become a crowd favorite. Of the roughly 500 active geysers in Yellowstone, Old Faithful is one of the most reliable in terms of when it can be expected to erupt. Th...
There is no evidence at this time, that Yellowstone is about to erupt. Mammoth Mammoth Hot Springs are the main attraction of the Mammoth District. These features are quite different from thermal areas elsewhere in the park. Travertine formations grow much more rapidly than sinter formations due ...
a large amount of new-born magma must enter the magma chamber before theseoldmagma erupt, causing disturbance and mixing of magma. The crust aboveYellowstonecannot withstand such a huge pressure,so basically, before all the magma to erupt, the pressure will be balanced, and the eruption will ...
Yellowstone National Parkhas the highest concentration of geothermal features of anywhere else on earth. The land literally smokes, bubbles and hisses. Numerous geysers erupt on a regular basis, including the most famous geyser in the world, Old Faithful. In this post, learn how to visit the ge...
000 years ago. This means the Yellowstone caldera — brimming with enough molten rock to fill the Grand Canyonmore than 14 times— is nearly due. Fortunately, supervolcanoes only erupt once the molten rock is heated enough to become “highly fluid.” So how does one go about preventing this...
Following the powerful Hebgen Lake Earthquake in 1959, numerous hot springs started to erupt as geysers, presumably due to increased pressure release from the deep geothermal reservoir and accompanying faster flow of ascending superheated waters (Marler and White, 1975. Geol. Soc. Am. Bull. 86,...
Of course, you can’t come to Yellowstone without seeing Old Faithful and for good reason. It’s really cool! It’s amazing how about every 45 minutes it erupts like clockwork. When you walk into the Visitor Center there’s a sign that tells you the next time it’ll erupt – give or...
