    Mount St Helens is recharging 36 years after 'deadliest blast in US history’: Volcano’s replenished magma stores are setting off a series of earthquakes, warn scientists

    • Scientists detected more than 130 small magnitude quakes since March
    • The earthquakes are steadily increasing, with up to 40 occurring per week
    • This behaviour indicates that Mount St Helens is slowly recharging 
    • But so far, scientists say there have been no signs of an imminent eruption

    The most active volcano in the Pacific Northwest has begun to stir again.
    Since March of this year, scientists have detected more than 130 small magnitude earthquakes beneath Mount St. Helens, with up to 40 occurring per week.
    This behaviour indicates that the volcano is steadily recharging – but while it may sound alarming, the experts say they haven’t yet spotted any signs of an imminent eruption.

    Washington’s notorious volcano is best known for its ‘cataclysmic’ 1980 eruption, which brought devastation and destruction that stretched on for miles, and visible ash fall nearly 1000 miles away. The event killed 57 people and blasted more than 1,300 feet off the top of the mountain. Now, scientists say its recharging

    THE NEW ACTIVITY 

    Beginning on March 14, 2016, scientists have detected low magnitude earthquakes from 1.2 to 4 miles beneath Mount St. Helens.
    In just the last eight weeks, there have been more than 130 earthquakes, mostly of magnitudes .5 or less.
    The largest so far has been a magnitude 1.3.
    Scientists say the earthquakes have been steadily increasing in numbers, with up to 40 occurring per week.
    So far, though, there have not been any atypical gas emissions, increases in ground inflation, or shallow seismicity. 
    This means that there are currently no signs of a potential eruption.

    Washington’s notorious volcano is best known for its ‘cataclysmic’ 1980 eruption, which brought devastation and destruction that stretched on for miles, and visible ash fall nearly 1,000 miles away.
    The event has come to be known as one of the 'deadliest eruptions in US history'. 
    It reawakened in 2004, spewing steam and ash up to 10,000 feet into the air.
    This activity continued until January 2008, and five months later, scientists concluded Mount St. Helens had gone to sleep.
    Now, the volcano is once again  recharging.
    Beginning on March 14 of this year, scientists with the United States Geological Survey’s Cascades Volcano Observatory have detected low magnitude earthquakes from 1.2 to 4 miles beneath Mount St. Helens.
    In just the last eight weeks, they say, there have been more than 130 earthquakes, mostly of magnitudes .5 or less.

    A similar pattern was seen at the volcano between 2013 and 2014, and, according to the USGS, recharging can go on for many years before an actual eruption takes place. They point to the activity at Mount St. Helens from 1987-2004, when the volcano slowly recharged for nearly 20 years
    The largest so far has been a magnitude 1.3.
    The ‘earthquake swarm’ located by the Pacific Northwest Seismic Network is steadily becoming more frequent, but the tremors are not strong enough to be felt at the surface.
    As the volcano recharges, ‘most of the action is happening far beneath our feet,’ explains Erik Klemetti, an assistant professor of Geosciences at Denison University, in Wired’s ‘Eruptions’ blog.
    While the volcano appears to be sleeping, magma is pushing its way upward.
    The scientists predict that the rising magma is applying stresses to the surrounding crust, pushing fluids through the cracks and spurring the small earthquakes.
    So far, though, there have not been any atypical gas emissions, increases in ground inflation, or shallow seismicity.
    This means that there are currently no signs of a potential eruption.

    Mount St. Helens is located in Skamania County, Washington. Roughly 520 million tons of ash were blown across the United States when it erupted in 1980, causing complete darkness in Spokane, Washington – 250 miles away from the volcano

    The images above show some of the aftermath of the 1980 eruption. Pictured left, a jogger more than 350 miles away from the site wears a mask to avoid breathing ash. On the right, fallen trees are shown along a logging road near the south fork of the Toutle River in Washington state
    They point to the activity at Mount St. Helens from 1987-2004, when the volcano slowly recharged for nearly 20 years.
    In September 2004, the volcano awakened with a swarm of tiny, shallow quakes.
    Beginning on October 1, the first of the small eruptions launched volcanic ash and gases into the air.
    This continued over the next three years, creating a lava dome in the volcano’s crater.
    Mount St. Helens has been quiet since 2008, but as of two years ago, scientists have confirmed that the volcano has slowly but surely begun to recharge. 

    THE CATACLYSMIC ERUPTION OF MOUNT ST. HELENS, 1980

    On May 18, 1980, Mount St. Helens in southwest Washington erupted.
    The cataclysmic event killed 57 people and blasted more than 1,300 feet off the top of the mountain.
    The eruption was trigged by a magnitude 5+ earthquake, which was accompanied by a debris avalanche.
    This abruptly removed the pressure at the top of the volcano, allowing hot water to quickly become steam, expanding ‘explosively,’ according to USGS.
    A wave of decreasing pressure travelled down the volcano to the magma reservoir lying below. The magma then began to rise and bubble, creating a massive eruption which lasted for nine hours.
    The debris avalanche travelled westward as far as 14 miles down the North Fork Toutle River valley, with a total volume equal to 1 million Olympic swimming pools.
    And, the lateral blast devastated the surrounding area nearly 19 miles west to east, and 12.5 miles to the north.
    In less than 15 minutes after the blast of hot material began, an eruption cloud had reached a height of more than 15 miles.
    Roughly 520 million tons of ash were blown across the United States, causing complete darkness in Spokane, Washington – 250 miles away from the volcano.
    The cloud circled the Earth in 15 days.
