Nevada Appeal - News: "Coming off a ground-breaking Tahoe tsunami research year, scientists are planning for a new season of underwater science, one they hope will pinpoint the date of a past monster wave.
Along the way they will investigate the potential for a tsunami in Tahoe's future, including analyzing the strength and stability of steep rock walls along the lake, which could collapse and cause another huge wave.
Last year, scientists believed they found definitive proof that a huge landslide caused approximately 100-foot waves to wash over what is now Tahoe City, sometime within the last 20,000 years or so."

:etter: Tsunami troubles: "Tsunami troubles
A tsunami on the West Coast? Hello Katrina.
I, and my husband, with bad knees and back, and unable to walk a couple of blocks, responded to the recent tsunami warning. We were watching TV when calls came from relatives, one in Seattle and another from Idaho, who had heard of a tsunami on the coast and were frantic.
'I haven't heard a siren,' I said, but I turned on several TV stations, and there was nothing. So often TV stations interrupt programming to announce a wreck on Interstate 5 or something similar. We waited, and finally the tsunami warning sounded.
So OK, let's go. We picked up three on the corner who had no transportation and had a baby to carry. Before we got to Holladay Drive, traffic stopped and the three, able to walk up a hill, took off at a run. Others ahead of our car followed suit, which left us, and others, in a helpless, hopeless situation waiting for the wave to hit.
In this retirement town, the city advertises that all should walk up the hill. I expect half the population will drown if the tidal wave is 20 miles out. We old people were lucky with this last alarm, but what about the next one? Few of us can walk two miles uphill.
The city needs to immediately sound the warning and notify Portland television"

Japan starts disaster-alert system using satellites | CNET News.com: "Japan, one of the world's most seismically active nations, on Friday began an alert system using satellites to instantly transmit warnings of natural disasters, such as tsunamis, to speed up evacuations.
Tremors occur in Japan at least every five minutes, and the country accounts for about 20 percent of the world's earthquakes of magnitude 6 or higher."

Experts warn of major quake in western Canada
VANCOUVER, Canada (AFP) - Seismologists warned that a "catastrophic" earthquake could strike the southwestern coast of British Columbia soon, Canada's Globe and Mail newspaper reported.
The experts noted rumblings from deep beneath the Pacific Ocean, along Vancouver Island, which could foretell a giant quake. But they said the probability of a quake was still low.
"Everyone drives their car every day, and the probability of getting in a car accident is small" although it rises during rush hour, Garry Rogers, a seismologist at the Pacific Geoscience Centre on Vancouver Island, told the Globe and Mail.
"Well, Vancouver Island is now driving in rush hour," he said.
The newspaper said the activity, known to scientists as episodic tremor and slip, emanates from the crush of the Juan de Fuca tectonic plate beneath the North American Plate, which is Canada's shoreline.
The Juan de Fuca plate runs from Vancouver Island on Canada's West Coast south to Northern California in the United States.

US Health Officials: How to Survive a Flu Pandemic - Science News - Playfuls.com - Science & Technology: "Case fatality ratio is the fraction of ill people who die. In the epochal 'Spanish influenza' of 1918, which killed at least 50 million people worldwide, the ratio in the United States was about 2.2 percent. Without a good mitigation strategy, a 1918-type pandemic today would kill 1.8 million Americans. It would be a Category 5, the most serious. "

EDITOR: the below article was written by my daughter, Lori. She is the Public Affairs Officer for Foothill College. She says this course will be offered on-line in about a year. I for one would like to enroll.
SUPHEAD: New Course
HEAD: Study the Science Behind Natural Disasters & Earth Catastrophes
From tsunamis to earthquakes to global climate changes, study the science of natural disasters and Earth catastrophes by enrolling in Foothill's four-unit GEOL 7 course. By examining natural disasters, this new course will help you develop an understanding of the basic scientific principles that govern our violent planet.
"Hurricane Katrina, the Great Sumatra Andaman Earthquake and the resultant tsunami-these are recent events that have increased public awareness of the awesome power of the Earth," says Foothill College Geography Instructor Christopher DiLeonardo, Ph.D. "To be good citizens of the planet, and be prepared to make the important policy decisions of the future, everyone should have a basic understanding of the science behind the awesome and oftentimes dangerous forces of nature."
The course introduces you to a cross section of local and regional problems as well as catastrophic processes of global scale. You'll discuss the treatment of these topics in popular media, and their impact on public policy issues.
A member of the Foothill faculty since 1990, Dr. DiLeonardo also conducts ongoing research on subduction zones like the one that generated the Sumatra Andaman earthquake and tsunami in 2004. His most recent work includes research on fault systems on the margin of Pacific Northwest that threaten coastal Oregon and Washington. He has worked as a researcher at the UC Santa Cruz Institute of Geophysics & Planetary Physics and as a research fellow at the NASA Ames Research Center in Mountain View.

Coastal Residents of Marin County, CA Unprepared for Tsunami :: PNNOnline ::
Coastal Residents of Marin County, CA Unprepared for Tsunami :: PNNOnline ::: "While residents of coastal towns in Marin county have a fairly high level of knowledge about tsunami hazards in general, many residents do not know the warning signs for tsunami and do not know how much time they would have to evacuate following either a tsunami warning for a tsunami generated somewhere around the Pacific Rim or a strong offshore earthquake occurring off the coast of northern California."
