Chile Earthquake– More Mega Quakes to Come

For those of you following the earthquake in Chile, there are two articles you may be interested in. Both come from Science Daily and are focused on different aspects of the zone.  One is very technical about the plates in the area and the other is about future quakes.

More Earthquakes for Chile? Seismic gap has not been closed

Here in the Pacific Northwest we have a demon in waiting.  A 9.0 off are coast that will alter the life of every man, woman and child in Oregon, Washington and Northern California. But for us, that is last big one we expect.  The clock resets itself for another 100 years or more.

Sadly, this is not the case for the good people in Chile. In 2010 they lived through an 8.8 and this April 8.0. Below is a sample of the Science Daily article:

  “After the strong earthquake that struck Chile on April 2 (CEST), numerous aftershocks, some of them of a considerable magnitude, have struck the region around Iquique. Seismologists doubt that the strong earthquake closed the local seismic gap and decreased the risk of a large earthquake. On the contrary, initial studies of the rupture process and the aftershocks show that only about a third of the vulnerable zone broke.”

Magnitude 8.2 earthquake off Chile: Thrust faulting at shallow depths near the Chilean coast

This one is aimed more for those of us that study or find a interest in earthquakes.  Think of it as the diagram for the plates of South America.

    “An M6.7 earthquake with similar faulting mechanism occurred on March 16, 2014 and was followed by 60+ earthquake of M4+, and 26 earthquakes of M5+. The March 16 earthquake was also followed by three M6.2 events on March 17, March 22, and March 23. The spatial distribution of seismicity following the March 16 event migrated spatially to the north through time, starting near 20oS and moving to ~19.5oS. “

“Get Ready for Anything: Before and After a Disaster”

VIA:  Get Ready for Anything

“Get Ready for Anything: Before and After a Disaster” is a free workshop series scheduled for April and May in the Sellwood-Moreland, Woodstock, and Brentwood-Darlington neighborhoods of Portland, Oregon. Falling so near to the March 11 second anniversary of Japan’s earthquake and tsunami, the series reminds us that the offshore Cascadia Subduction Zone threatens Oregon with a similarly disastrous event. The need to get ready is clear.

Workshop #1: Make a Plan & Build a Kit
The first workshop, “Make a Plan & Build a Kit,” will teach you how to create a family emergency plan, including communications, getting everybody back together, and planning for children, pets and household members with special needs. It will also show you how to assemble an affordable emergency kit, including simple solutions for emergency sanitation. This workshop will be repeated three times on the following dates and at the following locations…

  • Saturday April 5 — 2 to 5 pm
    Brentwood-Darlington Community Center, 7211 SE 62nd Ave.
  • Sunday April 13 — 2 to 5 pm,
    Moreland Presbyterian Church, 1814 SE Bybee Blvd.
  • Saturday May 3 — 2 to 5 pm
    Trinity United Methodist Church, 3915 SE Steele St.

Workshop #2: Help Friends & Neighbors Get Prepared
In a major disaster, you and your neighbors will be each other’s closest source of help. “Help Friends & Neighbors Get Prepared,” the second workshop, shows you how to engage neighbors in getting their households ready, and how to organize to help each other after a disaster. Also, you’ll learn about Neighborhood Emergency Teams and, if being a volunteer first responder appeals to you, how to become a NET member. Also much needed are ham radio operators who can provide vital communication links. This workshop will be repeated three times on the following dates and at the following locations…

  • Wednesday April 30 — 6:30 to 9 pm
    Service Employees International Union, 6401 SE Foster Rd.
  • Tuesday May 13 — 6:30 to 9 pm
    SMILE Station, 8210 SE 13th Ave.
  • Tuesday May 20 — 6:30 to 9 pm
    Reedwood Friends Church, 2901 SE Steele St.

Workshop #3: Secure Your Home Against Disaster
The last workshop, “Secure Your Home Against Disaster,” will address the safety of your living environment, with important information for both renters and homeowners. Speakers will cover fire safety and other non-earthquake hazards; non-structural measures for renters and homeowners to protect against earthquakes; and seismic upgrades for homeowners. This workshop will only be featured once, so don’t miss it!

  • Saturday May 31 — 2 to 4:30 pm
    Trinity United Methodist Church, 3915 SE Steele St.
