Scientists are deploying monitors to Mount Adams, a volcano in Washington state, after a surge in seismic activity.
According to the U.S. Geological Survey (USGS), Mount Adams typically experiences an earthquake every two to three years, but six earthquakes occurred in September alone, making it the largest earthquake in the month since monitoring began in 1982. recorded the highest number.
The earthquakes were monitored by the USGS Cascade Volcano Observatory (CVO) and the Pacific Northwest Seismic Network (PNSN) and ranged in magnitude from 0.9 to 2.0. According to the USGS, the quake was not felt at the surface.
The USGS said its monitoring capabilities are limited because there is only one seismic observatory near the volcano.
Lava continues to flow from Icelandic volcano even after eruption
CVO and PNSN have decided to establish a temporary seismic observatory near Mount Adams to help detect small earthquakes while obtaining more accurate estimates of magnitude, location, and depth. I'm planning. This data helps scientists assess the significance of increased seismic activity near volcanoes.
With permission from the U.S. Forest Service, CVO will establish temporary stations south and southwest of Mount Adams. Once activated, data is sent to CVO and PNSN in real time.
Recent Icelandic volcanic eruptions have subsided, but experts warn of more eruptions soon
Despite the spike in seismic activity, the USGS says there is no indication there is cause for concern and the Mount Adams alert level and color code remains green and normal.
Mount Adams is located in south central Washington, approximately 80 miles west-southwest of Yakima, Washington.

Mount Adams is the most prominent peak in the north-south Mount Adams-King Mountain volcanic region of more than 120 small volcanoes. According to the USGS, it is the second tallest volcano in Washington state and also the state's largest active volcano by volume and area.
According to the agency, over the past 12,000 years there have been four lava flows that started at the volcano's summit and two vents along its southern ridge. The flow typically only travels a few miles from the spout.

The USGS added that Mount Adams last erupted between 3,800 and 7,600 years ago.
But one of the biggest threats to people living near volcanoes is lahars, muddy streams of rock, ash, and ice that rush downstream like fast-flowing concrete.

The ice-capped peaks are covered with large amounts of rock weakened by hydrothermal fluids, which could generate mudflows if weakened by future landslides.
