VashonBePrepared Convenes Community Meeting on Landslide Risk VashonBePrepared invites the entire community to learn more about landslide risks on Vashon, a risk that ranks in the top three for the Island, right up there along with earthquake and severe weather. The informational meeting, which will include a question and answer session, will take place on Wednesday, October 29th,...

At least our knowledge of the Seattle Fault’s extent grew. This is according to USGS researcher Craig Weaver, as quoted in today’s Seattle Times article.

Apparently the quake occurred at the intersection of the Seattle Fault and another fault on the Olympic Peninsula. The article also references a 1995 quake near Vashon with magnitude 5 – which also turned out to be along the Seattle Fault.

The picture to the right (from the USGS)...

According to UW’s John Vidale, as reported by KING-TV and The Seattle Times, getting an early warning system in place for WA would cost some $17 million annually. We’ve a rudimentary system, but that’s seemingly not ready for prime time. It apparently is a priority for California’s legislators, but not (quite yet) ours. Maybe that will change!

More about California’s system – which gave a 10-second notice to the recent Napa quake is available at CBS.

As we reported a month ago, the USGS has released a new earthquake map. King 5’s recent story on this is at:

I haven’t vetted the following claims, but suspect they are readily verified. All too often the short term gain is overwhelmed by the long-term consequences…

The recent August 24, 2014 earthquake outside of Napa, California again demonstrated the seismic risk posed by a building’s nonstructural components. In general, the components of a building’s structural system that support the building and keep it standing—the frame, walls, and roof—performed very well in the Napa Valley earthquake. However, the nonstructural components of a building—the cladding, interior...

Voice of Vashon has started construction on Vashon’s new radio station KVSH, building as funds come in. And Islanders donated over $3,000 at Strawberry Festival so their fundraising campaign is at 93% of the $50,000 goal.

It'll take a couple more months of work to put KVSH-FM on the air but last week the all volunteer team erected the mast and antenna up top of the giant water tank just south of town.

This map shows, in purple and pink, the west-east line of magnetotelluric sensors that were placed north of Washington state’s Mount Rainier to study the volcanic plumbing system under the volcano. The sensors detect how the ground resists or conducts natural electricity within the Earth. Shown in yellow are seismic sensors that detect how fast or slow sound or seismic waves travel underground. Both methods were used in a new study that provides the most detailed look yet at the subterranean plumbing system that supplies the active volcano.

From http://www.usgs.gov/blogs/features/usgs_top_story/new-insight-on-the-nations-earthquake-hazards/

“Important changes in Washington are related to the addition of the Tacoma fault and changes to the South Whidbey Island fault. The Seattle region hazard has not changed significantly because we use a very similar model for the Seattle fault as was applied in 2008. We have not modified this fault using the geodetic model.” from the USGS report, Pg. 192

While there have been numerous historical problems (victim & rescuer safety, communication and conflicted goals) with asking untrained volunteers to help out during disasters, they were invaluable in the recent Oso slide rescue effort. It is pretty clear that they are very useful in a number of situations with some supervision or initial vetting.

According to this recent KOMO News piece, Seattle is warning residents to not inadvertently cause landslides.

"Eighty-four percent of the landslides that have happened in Seattle have, to some minor or major degree,...

According to this KOMO News piece, King County unveiled Monday, May 5th an initiative to re-map unincorporated county land over the next two years partially to help identify potential landslide areas.

King County will dedicate $800,000 to take advantage of much improved technology to remap the county using latest lidar equipment.

The last survey done in 1980 doesn’t have the resolution or clarity that is now available – though it famously aided identification of the previously unknown Seattle Fault....

Somewhat serendipitously, the New York Times Retro Report has come out with a special report on earthquake preparedness published April 13th – the same month as the Pacific Northwest’s 1949 and 1965 earthquakes.

They prepared an 11 minute video that unfortunately focuses mostly on California and Oregon – but hopefully will spur us all to action. California and the Pacific Northwest are clearly not yet adequately prepared...

Friday February 21, 2014, the Federal Communications Commission (FCC) approved Voice of Vashon’s (VoV) application for an FM radio station – along with over 1000 other low-power FM applicants nationwide.

Fourteen years ago a small group of volunteers dared to dream that Vashon could have its own live radio voice. Now, that dream has come true.

While much of the infrastructure is in place for the station to go live, a new FM...

A graph showing the relationship between eruption volume and time between eruptions, using the models presented in Carrichi and others (2014). Notice how for buoyancy-driven eruptions (in blue), the time between eruptions doesn’t vary much across a wide range of volumes. Image: Figure 3 from Caricchi and others (2014), Nature Geoscience.

The study’s upshot is that Yellowstone Caldera (and the other 20+ supervolcano sites) are more likely than previously thought to explode without the aid of an earthquake. A big one could drastically lower global...
