Scientists find major earthquake fault under Mount Hood

September 2, 2011PORTLAND, Or. – Mount Hood, the tallest mountain in Oregon, has a secret, scientists revealed. Covered by trees and plants is an earthquake fault that stretches for miles from the iconic mountain. The fault appears to have been recently active, and could be an earthquake threat today, reported the Portland Oregonian. Scientists said the last time the fault ruptured, possibly as a magnitude 6 or 7 earthquake, the ground ripped six feet (1.8 meters) apart. The fault was discovered by scientists flying over Mt. Hood using lasers to scan the terrain. The fault is about 20 miles (32.2 kilometers) long and stretches from the northern flank of Mount Hood to the Columbia River. Earthquakes are not a foreign concept to Oregonians. The nearby Cascadia Subduction Zone could unleash a magnitude 9 earthquake, similar to the size of the deadly earthquake that ruptured in Japan. Scientists aren’t sure how big of an earthquake could rupture from the new Mount Hood fault. The research team, from the Oregon Department of Geology and Mineral Industries, are now working to estimate the threat that the fault poses to nearby communities. “We don’t know where all the seismic faults exist in Oregon. We don’t know how often they cause earthquakes,” Oregon State University engineer Michael Olsen, told the Oregonian. “That leads to a lot of uncertainty when we try to design buildings,” he says, that are sufficiently resistant to earthquake damage. In the coming weeks, scientists will dig a trench above the fault line so they can examine the soil for clues about past earthquakes. Looking at how the gravel and dirt has settled after past quakes could tell scientists about the size of previous quakes along the fault. –Our Amazing Planet

    Well, ‘Mount’ Hood is a volcano, after all….

  3. Here’s a question – Could an earthquake from the fault by Mt. Hood trigger an earthquake from the Cascadia Subduction Zone? Or the other way around? I’m thinking that would pretty much devastate a good portion of Oregon between the earthquakes and the ensuing tsunami.

    Be blessed and Maranatha

    I live in Portland and I know that this is a seismic area and this article has me more concerned, just lights a fire under my as* to get even more preparded and organized. I hope people that live in my area understand that this is a very real treat – it is a matter of when not if………..Besides being physically prepared, I do my best to be spiriually prepared as well. I want to be as kind and good hearted and less less judgemental or materialistic than ever, nothing really matters except Love. All the things I have or want or whatever money I may have in the bank is just “stuff”. I can’t take it with me when I pass to the otherside where it doesn’t matter.. and as I remind people “it is easier for a a camel to fit through the eye of a needle than it is for a rich man to get into heaven”…I don’t know how I started to rant on about that lol – forgive me and peace to all 🙂
    Namaste –

      Forgive you for what Sufi? What a relevant & beautiful post. Thanks for sharing your feelings, mine are the same.

      Peace & Light to you.


  5. Well said, Sufi. Spiritual preparation is more important than anything else.

    I agree Sufi! Peace and love to you. I will pray for all those on the West Coast. It seems Alaska keeps getting hit with 7.0 earthquakes like yesterday I believe it was but the West Coast hasn’t seen anything major and I am worried about something happening soon.

    Blessings in Christ.

    Thanks all for your responses, it just seems everything there are rumblings from Mother Earth. Nothing suprises me much anymore. I am getting married in 2 weeks and off to a honeymoon in Maui for a week- I just really hope we can make it home without problems for many reasons but one being that I have been distracted and not as prepared and organized. All my best to all of you out there, we are all in this together and and we are family.
