Tsunami alert of Western Alaska Pacific...

[TiggerToo]

...anyone one out there?

Hope everyone on the coast can get somewhere safe.

I've got family further South on Vanc Island, working the boats.

Slept right through it.

Woke up to hear about it on the News. The west coast of the Island is a lot more vulnerable Port Alberni was hit hard back in the 50's. Tofino, Uculette, Port Hardy. The sirens went off an evacuations in the middle of the night. RCMP went door to door up in Hiada Gwaii would have been quite scary. Big Evacuations up in Alaska

It as a horizontal movement, with little risk of Tsunami, different fro the far more dangerous subduction quake, and the warning has been canceled. Zero risk of any outside tsunami getting inside Georgia Strait.

Someone I know on another forum lives quite nearby (by Alaska standards). He posted a few hours ago to say it was all a big anticlimax. They were warned of possible tsunami, but his local harbourmaster said it arrived as a wave about a foot tall

Woke up (on the mooring @ Cadboro Bay) to 6 missed calls and 4 texts from the wife. Can't say I discerned anything other than a typically choppy night.

Replied to her by text to say I was getting off the boat pronto, only to be berated for having the phone on silent. Naturally, the endless texting back and forth that ensued delayed me getting to land. Oh, the irony...

A colleague lives in Port Alberni, and the early 70's tsunami that went through actually washed against their house. Her hubby spent the night kipping in his work car park with the dog. If you dig down (as we archaeologists tend to do), you can see thick deposits that coincide with the tsunami events that have occurred over the last few thousand years.

tell us more please? sounds interesting. how about the UK, (apart fromt eh Bristol Channel one) any other evidence from the past? etc. thanks

The 1755 Lisbon earthquake's tsunami affected the South West of Ireland.


I believe one of the Canary Islands could potentially split in part causing a massive wave which would wipe out huge areas of the east coast of the USA.

They won't be missed.

The one I know about in Britain affected the NE of Scotland. You can see it in deposits around Inverness. IIRC, it occurred about 7-8000 years ago, in the Mesolithic

I was involved with some of the pollution countermeasures hardware after the Exxon Valdez incident in Alaska. This was 25 years after the extremely severe earthquake and tsunami in that area. The chart of Prince William Sound had still not been fully updated, merely drawing attention to varying levels of "Bottom Uplift". (As I recall, up to 25feet).

There were still piers and jetties standing which were now completely clear of the water, and some care had to be taken with pilotage, particularly when choosing an anchorage for the night. There were parts where the chart showed adequate water depth, which were now dry land. Whole villages had been wiped out, and many lives were lost.

That originated in a landslip off the coast of Norway (https://en.wikipedia.org/wiki/Storegga_Slide). Thi sis an interesting list of tsunamis that have affected the UK: https://en.wikipedia.org/wiki/Tsunamis_affecting_the_British_Isles

There are tsunamagenic turbidite deposits (a Bouma sequence) exposed near Tebay services on the M6, but they are ~450 million years old.

Tsunamis often turn out to be a damp squib. There was one forecast for Fiji when I was there a few years back - the alarms rang and everyone headed for the high ground, but as it originated off Chile I just sat on the dockside sipping my beer (free, since the bar-staff had fled). The 'tsunami' came and went - it was measured at all of 5 cm.

But not always. The Samoan tsunami of September 2009 was 4.5m high, and caught us right at the heart. A good sailing buddy was among 170 people killed.
