Do you know why these reports mention Hawaii, rather than (say) Vancouver and other coastal cities nearer to the epicenter, where I would imagine a tsunami would reach first?
- JorgeGT 9y agoThe page is specific to Hawaii, but you can go to http://www.weather.gov/ http://www.weather.gov/ and in the map, click your region and then "tsunami warning" or "tsunami watch" to see estimated times for other states. This is the tsunami watch notice for coastal areas of Oregon, Washington & California: http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=sew&wwa=tsunami%20watch http://forecast.weather.gov/wwamap/wwatxtget.php?cwa=sew&wwa...
- porker 9y agoThanks. I hadn't realised that these pages would exclude the coast of Canada either, and they'd have their own site. https://weather.gc.ca/warnings/index_e.html https://weather.gc.ca/warnings/index_e.html

- tempestn 9y agoYou can also quickly access this info at http://www.tsunami.gov http://www.tsunami.gov. Or at least normally it's quick; page is taking a good 10 seconds to load for me right now—under a bit of load, presumably. It includes Canada as well. (In fact, the BC Emergency site quotes from it and links back to it!)
- JorgeGT 9y agoI know but since tsunami.gov it's getting is getting hammered I figured out it's better to leave their bandwidth for people in risk rather than hit them with the HN frontpage effect.
- Turing_Machine 9y agoThe servers/pipes at tsunami.gov are clearly grossly underpowered for their intended use. Hopefully, they'll be able to get some equipment upgrades as a result of this.
- tempestn 9y agoI wonder what their infrastructure looks like. This is the poster case for a scalable cloud setup. 99%+ of the time their traffic is probably nearly zero, and when there will be a significant spike it's generally going to be predictable!

- mattnewport 9y agoVancouver is well protected from tsunamis caused by earthquakes in most spots (including this one) by Vancouver Island. The Greater Vancouver tsunami zone is the only one in BC not covered by the tsunami warning issued for this quake.
- api_or_ipa 9y agoVictoria is a better target city. Vancouver is sheltered by Vancouver Island where Victoria is considerably more exposed.
