4-15-2014 at 8.46.16 AMSomewhat 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...

VOV.1232x842Friday 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...

King County has told the local cities that it does not plan to provide snowplowing services to Tier 2 through 5 roads this winter due to budget cuts. Click here to see which roads in unincorporated King County are currently identified as Tier 1 through 5, and to see contact information for questions. (Hint only Vashon Highway is rated as a tier one road.)

The County may in fact plow as resources become available, but is suggesting that it may not be in a timely fashion. Details on the county’s ice & snow program can be found at: www.kingcounty.gov/transportation/kcdot/Roads/SnowAndIce.aspx

We are unaware of actual staffing changes locally so...

While scientists can't predict when a great earthquake producing a pan-Pacific tsunami will occur, thanks to new tools being developed by federal and state officials, scientists can now offer more accurate insight into the likely impacts when tsunamis occur. This knowledge can lead officials and the public to reduce the risk of the future tsunamis that will impact the west coast.

“Imagine a 7.2-magnitude earthquake hitting the Seattle Fault. Freeway overpasses crumble, a Lake Washington sieche (oscillating wave) takes chunks out of bridges.

This makes 2012 the second costliest year since 1980, with a total of more than $110 billion in damages throughout the year. The 2012 total damages rank only behind 2005, which incurred $160 billion in damages due in part to four devastating land-falling hurricanes.

The 2012 billion-dollar events included seven severe weather and tornado events, two tropical...
