Study Shows Seattle Fault May Have Origins in Ancient Tear in Continent

Seattle fault
The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed by Washington State Department of Natural Resources geophysicist Megan Anderson and others in a new study, could explain the fault system’s earliest history and help scientists improve hazard modeling for the densely populated region.

December 5, 2014Two joint studies are out this week and indicate that the United Nations’ Intergovernmental Panel on Climate Change (IPCC) 2013’s predictions of a global sea rise of a bit over 3 feet by the end of the century could be way off.

August 2, 2012Western North America experienced the strongest drought in 800 years from 2000 to 2004 – but that may be the new normal for the next century. Reduction in carbon uptake during turn of the century drought in western North America – pg 551 – 556, by a group of 10 researchers in the current issue of Nature Geoscience, looks at the reduced carbon uptake (by 51%) in drought stressed forests, based on a study of the 2000-2004 drought throughout western North America.

April 12, 2012Art Frankel and Craig Weaver of the U.S. Geological Survey gave a presentation to the Seattle City Council on Monday (as noted in this agenda) that has raised some eyebrows – and reaffirms our sensitivity to upcoming seismic disturbances. See their PowerPoint presentation or read on for a few copies of a few of their slides.

March 26, 2012An ‘ongoing’ effort (but apparently in abeyance since 2002?!) to create an accurate seismic model for the Puget Sound region and British Columbia is the USGS’ Seismic Hazards Investigations in the Puget Sound (SHIPS) project. Since March 1998 SHIPS has conducted a series of seismic studies to better describe earthquake hazards in the Puget Lowland and British Columbia.
Read MoreIs Vashon at Risk for Tsunamis?
March 21, 2012Most folks think of an overseas or Cascadia based quake as generating a terrible tsunami – and they are right. However such a tsunami is not likely to cause massive damage to Vashon from what I’ve heard – largely due to the moderating influence of the Straits of Juan de Fuca. (It will be interesting to verify this at our upcoming April 18th community meeting with Washington State experts).

March 11, 2012In “Quake catastrophe like Japan's could hit Pacific Northwest, new data show” M.

February 21, 2012Japan’s Tohoku earthquake last year has provided valuable data that is altering scientists’ understanding of our local Cascadia earthquake potential. Geologists have documented some 22 megaquakes over the last 10,000 years - every 200 to 1,000 years, averaging some 500 years. The region’s last was on January 26, 1700.

Global Warming Moves us Closer to the Ultimate Disaster
January 11, 2012Doomsday clock moves closer to midnight
Numerous articles (including USA Today’s) note that scientists have moved the hands of the doomsday clock toward midnight – as a visible metaphor for our lessened security due to our fuelish ways. It is notoriously hard to change our social (i.e., automotive) ways, but the consequences of our not taking a long term view are increasingly resulting in massive storm and economic damage today to societies across the globe.

January 11, 2012According to the inspector general (IG) of the Department of Homeland Security (DHS), state and local fusion centers and emergency operations centers could improve the response of their jurisdictions to terrorism and natural disasters if they talked to each other more often. Many fusion centers and EOCs surveyed do not exchange information.

December 8, 2011CBS notes that this year’s 12 disasters costing over 1 billion dollars each surpasses the number seen during all the 1980’s – even with inflation adjustments. In associated reports they note that the Intergovernmental Panel on Climate Change’s latest report indicated that additional small and large disasters can be expected with global warming.

June 7, 2011Seattle, Washington, June 1, 2011 – On Friday, March 11, 2011 at 2:46 PM (local time), the northeast coast of Japan was struck by a magnitude 9.0 (M9.0) subduction earthquake as the boundary between the Pacific and the North American plates ruptured along an offshore section. The rupture extended about 200 miles along the Japan coast, resulting in approximately 100 feet of vertical slip and causing a series of devastating tsunamis. A similar event along the Cascadia Subduction Zone could extend from Vancouver Island to Northern California, affecting western Washington and Oregon communities.

April 1, 2011In just the last two years, federal earthquake scientists have completed analysis of the Tacoma Fault. As it turns out, the Tacoma Fault actually runs directly across the center of Vashon, the community that could be most affected if it ruptures. The latest computer analysis indicates that shaking from the fault could be as severe as the recent earthquakes in Christchurch and Sendai. That makes it doubly or even triply important for all of us to be prepared to sustain ourselves for as long as 10 days at home until help can arrive.

March 16, 2011Today's 8.9 magnitude earthquake in Japan has had surprisingly limited impacts on the structure and routing dynamics of the regional Internet. Of roughly 6,000 Japanese network prefixes in the global routing table, only about 100 were temporarily withdrawn from service — and that number has actually decreased in the hours since the event. Other carriers around the region have reported congestion and drops in traffic due to follow-on effects of the quake, but most websites are up and operational, and the Internet is available to support critical communications.

March 15, 2011“This week's earthquake caused the main island of Japan to shift as much as 13 feet to the east, seismologists say. That may sound like a shocker, but it's just one of the natural changes that come along with an 8.9-magnitude temblor — like the 1.6-microsecond speed-up of Earth's daily rotation and the 4-inch shift in Earth's axis.”

If a major disease incident or bioterrorism attack were to occur today, the United States would not be read for it. That’s according to a new report supported by a grant from the Robert Wood Johnson Foundation.
In fact, the report says “there’s an emergency for emergency health preparedness in the United States.” It calls attention to significant local, state and federal budget cuts and the impact they have had on public health departments’ ability to maintain staff capabilities, and their ability to respond to crises.
Key findings include:
* 21 states were not able to rapidly identify disease-causing E.coli O157:H7 and submit the lab results in 90 percent of cases within four days during 2007-2008.
* 33 states and D.C. cut funding for public health from Fiscal Year 2008-2009 to FY 2009-2010.
* Seven states can not currently share data electronically with health care providers.
* 10 states do not have an electronic syndrome surveillance system that can report and exchange information.
* Six states reported that pre-identified staff were not able to acknowledge notification of emergency exercises or incidents within the target time of 60 minutes at least twice during 2007-2008.
* Six states did not activate their emergency operations center a minimum of two times in 2007-2008.
* Two states did not develop at least two After-Action Report/Improvement Plans (AAR/IPs) after exercises or real incidents in 2007-2008.
