Massive eruptions of the Yellowstone caldera have allegedly shaken the world three times – 2.1 million, 1.3 million, and 640,000 years ago respectively. Scientists from the United States Geological Survey are monitoring the activity of the supervolcano there for signs that it might erupt and cause devastation on a global scale.
The scientist-in-charge at the Yellowstone Volcano Observatory of the United States Geological Survey (USGS), tasked with monitoring the activity of its caldera, Mike Poland, has revealed that just in November, the University of Utah seismograph station recorded 107 earthquakes in the region, with the largest one having a 3.1 magnitude and occurring outside the park.
According to Poland, a further deformation of the caldera has been recorded.
The Norris Geyser Basin, which rose from 2015 until October 2018 but has remained steady for almost a year, also had a small subsistence event with a two-centimetre uplift in autumn 2019.
Debates Around Next Supereruption
His update about the movement of the Yellowstone caldera and changes in the region has come amid speculations about yet another supereruption that could inflict devastation spanning several states. As the volcano is thought to have erupted 2.1 million years ago, 1.3 million years ago, and 640,000 years ago, inflicting devastation on a global scale, The Daily Express reports, some have claimed, citing their calculations, the interval between the devastating events is 600,000 years, meaning that a planetary catastrophe is overdue. Such claims, however, have been dismissed by scientists.
USGS scientist Jake Lowenstein, who commented on the matter several years ago, argued that doing statistics on two eruptive intervals is “playing games”.
