Awakened this morning to a tsunami warning phone call on the landline from Sargent Barney warning of an impending tsunami to occur in just over half an hour at 7:23 a.m. He continued that it was due to a 9.0 earthquake in Japan hours earlier. Our coastal community is urgently called to prepare for a tsunami. At risk situations are at land elevations of 150 ft and below, especially low lying areas at & near river mouths here on the coast of northern California. The reverse-911 tsunami warning phone call suggested everyone go to higher ground immediately and it was 6:55am.
First action was to call a close neighbor without a land line suggesting we meet at our highest ground probably between 250-300 feet. Packing stuff I needed, making a pot of coffee, I am writing this post right now and it’s 9:17am.
I packed my car, went to highest ground here as suggested. Around 9am, a friend called to say the tsunami had been downgraded. The tsunami has passed (or so I believe right now). It was an excellent exercise.
Realized long after the early morning reverse-911 warning that the tsunami sirens were not sounded here on the coast.
A friend mentioned that a tsunami drill had been scheduled for March 11, not sure of the time.
