Still Waters Posted January 23, 2018 #2 Share Posted January 23, 2018 I've just come across this: Quote BREAKING Tsunami warnings have been lifted for coastal communities in B.C. https://www.ctvnews.ca/world/tsunami-warning-for-b-c-s-coast-is-cancelled-1.3771391 And now this: Quote Officials at the National Tsunami Center canceled the warning after a few tense hours after waves failed to show up in coastal Alaska communities. https://www.bloomberg.com/news/articles/2018-01-23/alaska-earthquake-prompts-tsunami-warning 9 Link to comment Share on other sites More sharing options...

Doc Socks Junior Posted January 23, 2018 #4 Share Posted January 23, 2018 (edited) Strike-slip fault on the under-riding plate south of the trench. Not much seafloor elevation change (a little, because there is an oblique element) which would be a tsunami generation mechanism. It's the mega-thrust earthquakes that one needs to watch out for. There have been many large megathrust earthquakes there (even within the last century) and there will be many more. Happily this one wasn't more problematic. https://earthquake.usgs.gov/earthquakes/tectonic/images/aleutian_tsum.pdf Edited January 23, 2018 by Socks Junior 5 Link to comment Share on other sites More sharing options...

Podo Posted January 24, 2018 #6 Share Posted January 24, 2018 I was evacuated this morning at 3:00-ish during the tsunami warning. The warning was lifted and nothing was damaged, but it was quite an eventful evening/morning. 8 Link to comment Share on other sites More sharing options...

GlitterRose Posted January 24, 2018 #8 Share Posted January 24, 2018 Yeah, well. Off-shore drilling is A-OK, ya know. Everywhere but Mar-a-lago, apparently. 1 Link to comment Share on other sites More sharing options...

Could you provide a reasoned mechanism whereby this earthquake was caused by offshore drilling? Or is this "thought" simply based on a misunderstanding of geology? 1 Link to comment Share on other sites More sharing options...

Everywhere but Mar-a-lago, apparently. @Socks Junior is right. There has been layer upon layer of tsunami deposits in that area for thousands of years, and sadly enough, layer upon layer of whole Indian villages. 1 Link to comment Share on other sites More sharing options...

What frustrates me is that American off-shore drilling legislation now have the potential to affect MY home and MY city, despite being a foreign nation. I'm not happy about this.
