Tsunami education on youtube
Listed below are 2 URLs for some video footage of the arrival of the tsunami in So. Cal as it entered the Ventura, CA harbor following the 8.8 earthquake in Chile on Feb 27.
The video shows how strong the currents can be in harbors and bays. The video was taken by the Ventura Harbor Patrol.

Chile Earthquake a Warning to the Pacific Northwest
Andrew Revkin of the New York Times wrote an interesting article about how the Chilean earthquake is a warning of what can happen to us here in Oregon. He even includes information from Oregon researchers, and a youtube video about how subduction zone earthquakes work and how devastating the tsunami was from the earthquake in Chile.
A prime case in point is Oregon. After the destruction of hundreds of poorly built schools in China’s Sichuan province, I wrote repeatedly here and in print about similar vulnerability identified by engineers and seismologists in that state, despite the clear record of devastating quakes and tsunamis generated by the Cascadia fault beneath the sea bed off the Northwest coast.

Coastal Sirens Are a Reminder of Tsunami Danger
On the Oregon coast, many of the towns have coastal sirens that are sounded when there is an immediate threat to the coast, such as a tsunami like the one we saw from the earthquake in Chile. While the tsunami was not very high here in Oregon (half a globe away), right at the Chilean coast the tsunami was up to 25+ feet in height!
The Curry Coastal Pilot wrote an article about this subject, and how the sirens are an important warning and tests help make people aware of the possibility.
