Cascadia Quake Potentially More Damaging than San Andreas or Japan’s Tōhoku

In “Quake catastrophe like Japan's could hit Pacific Northwest, new data show” M. Alex Johnson of msnbc.com also reports on last month’s reports at the American Association for the Advancement of Science – noting that the Cascadia quake has numerous parallels with Japan’s Tōhoku disaster one year ago.

In Memory of the 2011 Japanese Earthquake and Tsunami

Just a brief note to commemorate those whose lives have been disrupted and lost by the Tōhoku disaster one year ago today.

Cascadia Mega-Quake Threat-- Even Larger than Previously Thought?

Japan’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.

Japan Clears the Debris

If you appreciated my 14 March post that mentioned the ABC site showing before & after images of some tsunami scenes, you’ll likely also appreciate this somewhat similar set of photos from the Sacramento Bee that show 3 sequential images shot from the same perspective – of maybe a dozen different scenes. Thanks to Cathy Rogers & Jill Watson for alerting us to these.

Science & Analysis of Japanese Quake Paints a Grim Message for the Northwest

Oregon and Washington are likely to have a very serious earthquake in future decades, according to a disturbing article in the Oregonian.

Paul Nichols’ Time Lapse Quake Maps

If you’ve not come across them, Paul Nichols has created several time lapse earthquake maps. Working at the University of Canterbury's Digital Media Group, he takes USGS or GeoNet data and plots it using the Google Maps API to create a fascinating animation.

SEAW Engineers to Present Observations from Japanese Earthquake Reconnaissance

Seattle, 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.

Support Japan

After lunch today I caught this poignant reminder of the recent Japanize triple disaster – and the world-wide support for the Japanese.

Japanese Internet Stays Up – even When Electricity Doesn’t

Today'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.

Visual Results of Japanese Tsunami

www.abc.net.au/news/events/japan-quake-2011/beforeafter.htm has incredible photos of the Japanese earthquake’s aftereffects – as contrasted with an initial view of the same scene.

Japan-- 5th Largest Earthquake

Gauges at the University of Washington lit up for hours after the initial Japanese earthquake, which now has been determined to be the fifth largest earthquake in the world since 1900.

Quake most expensive yet

Losses from the quake, tsunami and fires will total at least $100 billion, including $20 billion in damage to residences and $40 billion in damage to infrastructure such as roads, rail and port facilities, catastrophe modeling firm Eqecat estimated.

Quake shifts Japan 13’ East

“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.”
