Mount St Helens could erupt again as scientists closely monitor a lava dome rising at five metres a day. A USGS scientist adds:”What is really phenomenal is how much rock is still coming out of the ground. It’s now taller than the Empire State building. It’s coming up at five metres a day, more than 200 metres wide and it’s right here in our back yard.

On May 18, 1980, Mount St Helens erupted in the US state of Washington. The blast, which measured 5 on the Volcanic Explosively Index, has been declared as the most disastrous volcanic eruption in modern US history. A huge column rose 80,000 feet into the atmosphere and deposited ash in 11 states, killing at least 57 people and causing more than $1billion (£770million) in damage.

Scientists are now closely watching the volcano to make sure they are prepared in case the same happens again. 

Amazon Prime’s “Mega Disaster: It’s Happened Before, It Will Happen Again series revealed how a team of volcanists monitor the ticking time bomb.

Rick LaHusen, from the United States Geological Survey (USGS), detailed how they use an instrument known as the “Spider” to keep an eye on volcanic activity. 

This is a GPS antenna which receives timing signals from satellites and lets us locate exactly what is going on inside. The signals go into the computer system and then the data comes out at the request from computers back in the office.”

However, Dr LaHusen’s analysis of the data provided a chilling revelation. He added: “What is really phenomenal is how much rock is still coming out of the ground. It’s now taller than the Empire State building. It’s coming up at five metres a day, more than 200 metres wide and it’s right here in our back yard.

Lava domes are formed by viscous magma being pushed to the surface below and piling up. Like lava flows, they typically do not have enough gas or pressure to erupt explosively butthey are sometimes followed by explosive activity. 

He is certain a future eruption of some sort will happen, though.

Since 1980, the area around the volcano has experienced tens of thousands of small earthquakes and numerous minor eruptions. Most notably, as of 2004, the volcano has been continuously erupting lava, which has created a large dome that is still growing.

  1. la terre a maintenant atteint un stade avancé et nous pouvons voir sa surface
    commencer à se briser tous comme les éruptions volcaniques, les tremblements de terre
    et raz de marée qui vont continuer à devenir encore plus grave avec des effets cataclysmiques
    partout sur la terre. le monde doit se préparer à affronter les événements dramatiques qui vont se produire.

  2. they could have make it safe and made millions from geothermal electricity all these do nothings , doing nothing all the years.
    that americastan today.

    • Impending Solar Flash Event Supported by Scientific Studies & Insider Testimony

      While I was searching for the information about this Solar Flash, I encountered virus warnings. Government and all the Reptilian Agencies do not want you to know this fact. They want you to think “Everyday is the same forever”.

  3. Government & Reptilian agencies are really afraid of Dutchsinse! They do not want people to know the Earth Change going on, right now.
    https://www.kiro7.com/news/debunked-article-claiming-seismic-unrest-at-st-helens-lacks-scientific-support/71813744

    “Our director would call Dutchsinse ‘complete hogwash and has no shame in promoting horror notices for clickbait,’” a PNSN (Pacific Northwest Seismic Network) spokesperson wrote to KIRO 7 in a statement.

    PNSN encourages people to rely on organizations like U.S. Geological Survey for information rather than bloggers.
