Other sources say that more research on the subject shows that the waves would taper off the farther they get from the island. Subduction zone earthquakes generally move a lot more water than coastline landslides. There have been destructive tsunamis due to landslides on the western Atlantic before (Newfoundland is a good example) but those were local and the most severe damage didn't extend very far.

The USGS on its own website does not acknowledge landslides on the opposite side of the Atlantic as a tsunami risk for the eastern US.

There's no denying that a La Palma eruption and landslide could be locally devastating though. There's evidence of something similar happening in the Cape Verde Islands farther south.

Yall were just asking why the USGS and news isn't talking much about this. My guess is they take the more conservative opinion that there isn't much to worry about, at least here.

I sincerely hope that the predictions I have read, which are worst case scenarios, BTW, are wrong and as I stated in my opening remarks to this thread, it could be just a ripple by the time it gets here or it could be much worse. One always prays for the best, but expects/plans for the worst.

As for USGS and the gov't in general, they also would not give, as a matter of policy, any alert to the US population, if there were an immediate (as in 'incoming') threat of nuclear attack. That would explain the USGS's lack of coverage while the European agencies are reporting the activity at La Palma (which is getting worse today, BTW).

Being in the cross-hairs of this event, I am watching intently and have had an interest in the 'event' since the first movement in the 70s that stopped slipping. What is disconcerting is that the activity is increasing and reports are of harmonic distortions being detected, which indicates significant magma activity under the island.

I think we must pray for a modification of the event, that the landslide is mitigated and the effects lessened. May God have mercy.
