Cascadia is a proposed independent nation in the Pacific Northwest, usually composed of Oregon, Washington, and British Columbia, that would be formed by seceding from the United States (and Canada).
Water and Forests
According to Sightline Institute "Cascadia is defined by water and forests: it encompasses all of the watersheds whose rivers flow through the temperate rainforests on the northwest Pacific coast."
Statistics of the Republic of Cascadia:
- Name: The Republic of Cascadia (long form), Cascadia (short form)
- Capital: Cascadia
- Area: 855,762 sq km
- Population: 14,220,981 (2005 est)
- GDP: US$323 billion (1996 est)
- Language: Cascadese (a dialect of English)
- Time System: Metric Time
Cascadia Subduction Zone
It will take only minutes to reach the coasts of Oregon, Washington, southern British Columbia, and northern California with wave heights reaching close to 12m (~36ft) in some scenarios.
Geologist Brian Atwater shows a cross-section of cedar killed by the last Cascadia earthquake in January, 1700. Atwater discovered proof that a recurrent massive subduction zone tsunami hits the West Coast every 300-450 years (Video presentation).
According to calculations by Chris Goldfinger, a geologist at Oregon State University, there's an 80 percent chance that the portion of the fault off southern Oregon and Northern California would break in the next 50 years.
Three Implementing Organizations are responsible for construction and development of the overall program. Woods Hole Oceanographic Institution and its partners, Oregon State University and Scripps Institution of Oceanography are responsible for the coastal and global moorings and their autonomous vehicles.
Earthquakes create various types of waves with different velocities.
P-waves, for primary waves, are produced by earthquakes and recorded by seismometers. They are the highest velocity and therefore the first to be recorded. The S-wave, or secondary wave, is perpendicular to the direction of wave propagation, like waves in a rope, as opposed to P-waves like those moving through a slinky.
Each tsunameter has a pressure recorder anchored to the seafloor. The recorder’s readings were relayed to NOAA’s network of geostationary weather satellites (GOES) in the first DART models.
The Coast Guard uses dozens of buoys bobbing off U.S. coastlines from Maine to Alaska, which also extend the reach of a Automated Identification System. It monitors large vessels heading in and out of ports, extending the network and relaying information from hundreds of miles off shore.
An international warning system was started in 1965, the year after tsunamis associated with a magnitude-9.2 temblor struck Alaska and the West Coast in 1964. It is administered by NOAA. The PMEL Tsunami Research Program seeks to mitigate tsunami hazards to Hawaii, California, Oregon, Washington and Alaska.
Member states include all the major Pacific rim nations in North America, Asia and South America, was well as the Pacific islands, Australia, New Zealand, France, which has sovereignty over some Pacific islands, and Russia. The Indian Ocean has rarely experienced tsunamis and does not have an active warning system.
James Roddey, a geologist known as Oregon’s “Prophet of Doom,” explains it it stark terms. The coming Cascadia event could tip the scales at a magnitude above 9.5 – larger than all 20th-century earthquakes combined, according to Roddey, and last up to five minutes (Video).
"Several of the 10 bridges across the Willamette River will collapse—the Steel Bridge, Sellwood Bridge and Marquam Bridge, most likely—and the rest will be impassible. Big Pink and other office towers will sway so violently their granite and glass façades will shear off and crash into the street, piling rubble up 4 feet deep. The Multnomah County Courthouse will tumble. Underground gas, power and water lines will be pulverized. The soil beneath the Portland International Airport will temporarily turn to soup."
The 2011 Sendai earthquake and tsunami, with a magnitude of 8.9, made it the largest earthquake to hit Japan in recorded history and the sixth largest in the world since records began and may be a sister of the Earthquake and Tsunami that is likely to hit the Northwest in our lifetimes.
OpenStreetMap has good map data of affected regions in Japan, and the Humanitarian OSM Team is on hand to help. CrisisWiki is an editable directory of resources related to disasters and crises around the world.
Social media and the web have become the go-to for real-time information, says Mashable. Facebook sites that cover the quake include JapanEarthquake, Solidaritytsunamimarch2011, and the The US Weather Service.
