Mount Rainier, the active volcano over the southwestern state of Washington, began to rumble on Tuesday – very easily.
A swarm of small earthquakes was found under the monitoring of the mountain triggers focused by the officers. However, the researchers have found that there is no threat of an outbreak.
The crowd of earthquake began shortly before 1:30 a.m. local time, according to the Cascades Vulcano Observatory of the US Geological Survey and the Pacific northwestern seismic network. Since the beginning of the swarm, hundreds of tiny earthquakes have occurred near the volcanic tip, with the size of the largest being detected at 1.7.
The origins of the earthquakes were recorded between 1.2 and 3.7 miles below the summit of the mountain. According to the KPTV, nobody was felt on the surface.
Since Mount Rainier is an active volcanic officer, the seismic activity did not say abnormally and emphasized that there is no reason for alarm. The alarm level of the volcano has remained normal, and its color code for green, which shows typical activity.
“Mount Rainier usually sees about nine earthquakes per month,” said the agencies in a statement after the swarms were discovered. “Such swarms happen once or twice a year, although this is larger than usual.”
The last important earthquake on Mount Rainier occurred in 2009 and rumbled on for three days. More than 1,000 seismic events were recorded with the most extensive registration of a size of 2.3.
Previous swarms were attributed to liquids that circulate under the mountain, and the interaction with errors deep underground and not with volcanic activities.
According to the US Geological Survey, the last eruptive period for Mount Rainier occurred around 1,000 years ago, but even with this incident there were no lava flows. The last large destructive outbreak, which reached the state of Washington, was not in Mount Rainier, but at Mount St. Helens – about 50 miles away, but part of the same mountain chain – 1980. This outbreak killed 57 people.
The snow -covered Mount Rainier is located in Mount Rainier National Park, about 59 miles southeast of Seattle. The mountain is the highest summit in the state of Washington and on clear days of Seattle.
