This week on the Oregon Coast, thousands of residents and vacationers will be practicing for "the big one." The State is conducting voluntary tsunami drills so that people can get a good idea of how fast they can make it to higher ground. In an emergency, people on the Oregon Coast would probably only have about 10 or 15 minutes to get to safety. Organizer James Roddey says people in Central Oregon would be affected by a large earthquake and tsunami because essential services would probably be affected. "And if roads and bridges are damaged to point where no food or fuel is coming over, the Cascades to Central Oregon and I-84 is damaged and I-5 is shutdown; then Central Oregon becomes isolated just like the rest of the State, and ends up waiting for help to arrive.” He says the 13 million people West of the Cascades on the I-5 Corridor would most likely get that help first; so Central Oregon would need to be self sufficient for perhaps several weeks.
