Volcano and Earthquake watch

_127966025_chilevolcano.jpg


 

So a little one in Northern California. I know it’s easy to join the dots but the big cascades one is overdue. Overdue obviously means little but yeh. We have kinda been told that the san Andreas one is the one everyone fears but the cascades subduction zone is where you will get massive movement and tsunamis
 
Two earthquakes [first was 7.8 and second of 7.5 magnitudes] a few hours and about 80 miles apart ...
Plus there will be aftershocks, so I'm expecting the toll to be high, very much more than 10,000.

My hope is that the Disasters Emergency Committee will announce an appeal pdq !

WHO is now saying it could be 20k :(

Not entirely surprising - having two quakes of that sort of magnitude more or less back to back is very unlucky.
IIRC some of the aftershocks already reported have been quite substantial, and no doubt there will be more, sadly.

Hopefully not in the next 48 hours - the time window for most of the successful casualty retrieval. There are many rescue teams already on their way / recently arrived, some including specialist search dogs.
 
No, I didn't [too far away]
But I was present on the Lleyn Peninsula in 1984, and was woken by one of the larger aftershocks, also felt another one that was mid-afternoon a few days later.
Definitely a weird sensation.

Currently living close enough to Spadeadam / DNV to feel / hear some of the shenanigans going bang there.
Including the test done to see if Guido had enough gunpowder to blow up the houses of parliament, that well rattled our windows !
 


As for 07:04 there is a threat to life from potential tsunami with heavy waves reported in Tonga.


Scientists have tried to calculate the power of the event.


Scientists have used eye and earwitnesses accounts, along with data from tide gauges, satellites, evidence of broken windows and other sources, to calculate that the eruption of the Hunga Tonga-Hunga Ha’apai volcano, which occurred on 15 January 2022 and was felt around the world, likely involved five blasts. The last of them released energy equivalent to about 15 megatonnes of TNT.


That is around 1,000 times more powerful than the bomb that was dropped on Hiroshima in 1945, and puts the volcanic event on a par with the most powerful nuclear device ever detonated by the US: the Castle Bravo bomb detonated at Bikini Atoll in 1954.
