Tsunami warning sirens went off at about 8:00 last night. We're at almost 500' elevation so we were fine. I was interested as I watched the news at the preparations people were making. Some people went for groceries, even more went for gasoline. I heard a woman talk about lowering the temperature on the refrigerator and backing up the computer. I hadn't thought of that. The tsunami wave never amounted to much, about 1.5 feet in Hilo harbor, but it caused me to reevaluate our emergency plans.
