Planning is everything and should be done before a disaster strikes. As I said, amateur radio isn't going to replace government operated tsunami early warning systems, but it could augment it. Just like most early warning systems for severe weather are government operated, hams can do a bit to help. Just look at all of the weather stations on APRS. You may recall the tsunami that hit Port Alberni BC in 1964 (that the right year?) 2000 km south of the Anchorage Alaska earthquake. Early warning wouldn't have helped much in Anchorage as there wouldn't have been time to evacuate, but further down the BC cost it would have been an asset. While Port Alberni suffered signifcant damage, not a single life was lost there. That was pure luck. Now, 40 years later, there are solar powered sirens that are tied into a tsunami early warning system. Who knows... maybe a communication failure in the circuit that triggers the local siren can be bypassed and the alarm sounded to a community of several thousand if the phones are still working, or if someone can get through on radio (amateur or otherwise), or if an alert send by HF, APRS, packet or whatever gets through and is delivered to someone that can hit a manual button... or it could be as low tech as someone with a megaphone shouting out a warning before hightailing it to high ground. Not everyone will listen, but some will. That's a lot of "what ifs" but the more planning there is, the more of a difference communication can make. Even after a disaster has taken place, having backup communications can help save lives.

They could do something. Yes, the public needs to be educated. I was aware that tsunamis can be devastating. If I heard one was coming a few days ago, I would have probably stood on a knoll a hundred yards from the beach and watched it coming. Having seen the results on the tube over the last day so, I would head to high ground as quickly as I could... while yelling into a megaphone if I had one. With two hours warning, thousands of lives could have been saved. With five minutes warning, at least those that listened would have had some kind of a chance.

I agree, amateur radio, APRS & connected packet isn't going to replace things like tsunami warning systems or severe weather alerts broadcast by the media, but it could be a backup system. Even if it helped by warning just a few hams and those around them, it is better than not having amateur radio in place.

I agree somewhat. Technology won't solve all human and political problems, but it can help a bit.
