A 1-foot tsunami isn't significant, but this is a good reminder that bad tsunamis can happen out of the blue.



They apparently haven't located the source yet.

Chron.com, among others, took a look at the Gulf's tsunami risk after the recent Kamchatka megathrust quake. Submarine landslides are the black swans here, though this layperson can't discount a volcanogenic one someday from Kick-'em-Jenny or some other firehole -- people tend to overlook volcanoes as tsunami risks, but again, this is an extremely low probability for the Gulf.

Aha! It was a glacier collapse event.

Correction (my fault): It was a rock slope collapse onto a glacier. Details and links.

Some images from the site. The landslide did reach water, causing a tsunami that was "just a tad" more than 1 foot high by several tens of feet. Some people reportedly were in the area, including a couple of kayakers who were taken on a wild ride, but there were no casualties reported.

Tsunami evacuation towers in Japan are awesome. Per the tweet, these were finished four years after the 2011 disaster.



Don't think we have any of those here but I have read that OSU's new earth/marine science buildings along the coast are also built with vertical evacuation in mind.
