Yellowstone volcano eruption: how long does it take for a yellowstone eruption? Is the caldera active? | Sciences | New

The Yellowstone volcanic hotspot was rocked by 81 earthquakes in February in the US National Park, as detected by seismographic stations at the University of Utah. The United States Geological Survey (USGS) said earthquakes of various sizes have been reported in the region. The largest was magnitude 3.1, located 14 miles south of Montana on February 16 at 2:22 p.m. local time. The strongest earthquake of a “swarm” of 17 measured a magnitude of 1.7 and was located five miles north of Montana.

The USGS said the seismic activity was nothing to worry about, saying, “Swarms of earthquakes like this are common and account for about 50% of the total seismicity in the Yellowstone area.

How long is Yellowstone overdue for an eruption? Is the caldera active?

An eruption of Yellowstone would kill thousands of people and destroy entire cities, even disrupting entire continents.

In Yellowstone’s last eruption 630,000 years ago, the supervolcano spat 240 cubic miles of ash and rocks into the air.

Recent activity has seen the caldera – the cauldron-like crater that forms as a result of a major volcanic eruption – sink, continuing to the present day.

But while Yellowstone National Park says subsidence correlates with seismic activity, that doesn’t mean an eruption is imminent.

The park says Yellowstone will “likely” erupt again, but not for at least thousands of years.

A rash is unstoppable and beyond the control of human abilities.

However, the most commonly expected type of activity would be lava flows.

USGS says there have There has been no “significant change” in the deformation of the Yellowstone surface recently.

In its last update on March 1, the science agency wrote: “The ground subsidence of the Yellowstone caldera continues, as since 2015, at a rate of a few millimeters per month.

“In the Norris Geyser Basin area, GPS data shows no vertical deformation (the area has shown little net change since October 2018).”

The volcano alert level is currently set to normal.

The park, which celebrated its 147th birthday on March 1, said there were four water eruptions from Steamboat Geyser last month on February 1, 8, 16 and 26.

Steamboat is the tallest active geyser in the world, with eruption levels reaching 300 feet high.

The USGS said: “The flow measured at the Tantalus flow gauge suggests that these eruptions may have been smaller than past events in the current streak (which began in March 2018), although it is difficult to tell. confirm without direct observations. “
