The Yellowstone eruption area collapsed upon itself, creating a sunken giant crater or caldera 1,500 square miles in area. The magmatic heat powering that eruption (and two others, dating back 2.1 million years) still powers the park’s famous geysers, hot …

2021年3月20日 · The area in and around Yellowstone National Park has seen tremendous volcanic activity in its past. Three giant eruptions have occurred between 2.1 million and 640,000 years ago. The most recent eruption formed the Yellowstone caldera. Since then, the park has seen roughly 80 mostly non-explosive eruptions.

2021年3月20日 · A caldera is that volcanic depression that occurs when a magma reserve is emptied, the “caved in,” typically round in shape, section. The Yellowstone caldera is 35 miles wide and 50 miles long, although a recent study suggests the caldera is …

2021年3月20日 · Yellowstone National Park consists of three enormous calderas that erupted about 2, 1.2, and 0.6 million years ago. The most recent caldera is 45 km across and 75 km long! Caldera-forming eruptions are the largest eruptions on Earth.

2021年3月20日 · The Yellowstone eruption area collapsed upon itself, creating a sunken giant crater or caldera 1,500 square miles in area. The magmatic heat powering that eruption (and two others, dating back 2.1 million years) still powers the park’s famous geysers, hot springs, fumaroles, and mud pots.

2021年3月20日 · Using thermal satellite images, scientists take the earth’s temperature hundreds of miles away from a destination to hopefully predict volcano eruptions.

2021年3月20日 · Since 2004, Yellowstone National Park officials have been studying the thermal features around their park with the hope of predicting if and when the world’s most geothermically active area, namely their own backyard, might blow.

2021年3月20日 · Yellowstone is one of the 21 under-monitored volcanoes in the High threat group. USGS officials emphasized that this does not mean that the geologic conditions at Yellowstone have changed. The activity at Yellowstone remains consistent with historic levels.

2021年3月20日 · The National Park Service has been monitoring the Yellowstone volcanic activity very closely for the last 30 years. Their prediction? The chance of a catastrophic eruption in the next 1,000 -10,000 years, is “very unlikely.”

2021年3月20日 · “Yellowstone is one key area where arguments against plumes are focused,” Christopher Kincaid, a geophysical fluid dynamicist at the University of Rhode Island, told Yahoo News. Kincaid decided to test the mantle plume theory.
