Yellowstone Volcano: 98 earthquakes revealed in latest report by USGS
YELLOWSTONE – In the latest update of the Yellowstone volcano by the United States Geological Survey (USGS), October registered 98 total earthquakes in the Yellowstone National Park region. This seismic activity shows 21 more earthquakes than those reported in September. Although there was more activity in October, the highest magnitude was lower than the one reported in September. The volcano’s current alert level is “normal” and current aviation color code is “green.” This is clear indication that no massive eruption of the supervolcano is imminent. According to the USGS, their information comes from the University of Utah Seismograph Stations and is responsible for the operation and analysis of the Yellowstone Seismic Network. “During October 2014, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, reports 98 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a small earthquake of magnitude 2.7 on October 29, at 3:55 PM MDT, located about 17.5 km (11 miles) south-southwest of West Thumb, YNP. This earthquake is part of a small swarm of 15 earthquakes that occurred over six hours.
“Yellowstone earthquake activity in October is at low background levels.” As the Inquisitr reported for September, nearly half the earthquakes were registered for the Yellowstone volcano in September than there was in August. August had 207 and 71 were reported in September. The strongest earthquake that month was September 24 when it reached a magnitude of 3.2 about 9 miles south of Mammoth.; no earthquake swarms were reported in September. Ground deformations were updated by the USGS as well in the October report. “Ground deformation was also reported in north-central Yellowstone. The rate of subsidence is holding steady at about 5 centimeters a year. “The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.” The National Park Service posted a notice on its website that Yellowstone volcano won’t erupt anytime soon despite rumors implying otherwise. “Though another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years.
“The most likely activity would be lava flows such as those that occurred after the last major eruption. Such a lava flow would ooze slowly over months and years, allowing plenty of time for park managers to evaluate the situation and protect people. No scientific evidence indicates such a lava flow will occur soon.” EP
