Small earthquake strikes off Oregon coast: tension mounting on dangerous Cascadia fault

Cascadia Fault Subduction Zone TEP
April 2014OREGON – A magnitude 4.7 earthquake struck on Friday off the coast of Oregon in the Pacific Ocean, the U.S. Geological Survey said, but it did not trigger a tsunami warning. The USGS said the quake, which was only 6.2 miles below the seabed, was centered 132 miles west of Bandon, Oregon. The Pacific Tsunami Warning Center showed no tsunami warning in effect following the small quake. –Reuters
Major stress is erupting along a very dangerous region of the Cascadia Subduction zone – indicating seismic tension on one of the most dangerous faults in North America is mounting and should be monitored very closely. –TEP

  1. It is no longer a matter of if a major earthquake hits the Oregon Coast, but when. The pressure gradients have been shifting at both ends of the Cascadia Subduction Zone for over two years with no real change in the center. When it happens look for it to happen somewhere between Astoria and Florence and be at least a magnitude 8.0, if not significantly higher. God help us all who live here…

      Such a beautiful state, but obviously nobody is in touch with reality or they wouldnt build all their cities and universities right on/near the fault line!


      • Actually the Cascadia Subduction Zone lies about 50-70 miles off of the Oregon Coast. In Oregon itself there are just minor fault lines. The problem isn’t so much where everything is built but how they are built, and the fact that it has just been in the last few years that anyone has taken this threat seriously. The majority of the people here, however, are still blissfully ignorant of the danger.

    1958 Lituya Bay Alaska, check it out!
    Cascadia, because of the 30 year Volcanism no one wants to talk about, is ripe to break. Mt. Ranier is now active, Mt. St. Helens also active, and don’t dismiss the dozen other Volcanoes on this 700-800 mile stretch called Cascadia. 9.5 quake or higher is possible. When earth was forming quakes in the teens were common, 11.0 +.
    Next, Canary Island chain, El Hierro, La Palma are receiving more and more magma. Maybe you have heard about the expected East Coast of US Tsunami? Think of the Atlantic and Pacific Oceans as a very large bath tub. All areas will be hit in all directions. One thing people should know especially on west coast. Don’t think that because you are in back of an area such as we see in Washington and Oregon that the Tsunami won’t find you; it will! Tsunami’s are the one large waves that will wrap around and go up tributaries, etc. And can be several waves.
    CA has its San Andreas over 800 mile stretch, both north and south will inevitably break. 1906 quake broke north to south and pretty much destroyed the natural break in between n, and s San Andreas; there is no stopping either ends from meeting. There is also a possibility that when the San Andreas breaks if south to north that it will cause the Cascadia Fault to break, etc. A no win situation.
    Knowledge is power folks, maybe this info will get you to read more and be better prepared.

    I blogged a few days ago – I have been watching and noting also.

    The Juan de Fuca plate is taking a beating! A friend had a vision of a great tsunami
    from its break up, and anothe friend who lives there has a feeling of something bad impending.
    She has seen earthquake clouds.
