5.2 earthquake 165 miles south of New Orleans

I believe there is a fault offshore of Oregon, that, if a large earthquake occured, could generate a large tsunami along that coastline.

But this is on the west coast. For this coast from Alaska to California there is definitly a tsunami thread. That's why they installed a tsunami warning system there.

tsunamis are caused by earthquakes in subduction zones.the subduction zone earthquakes are the 9.0+ monsters like the one in Indonesia which is the reason why it has so many volcanoes

Just FYI, to help ya'll sleep better at night.

But huge landslides and the mega-tsunami that they cause are extremely rare - the last one happened 4,000 years ago on the island of Réunion. The growing concern is that the ideal conditions for just such a landslide - and consequent mega-tsunami - now exist on the island of La Palma in the Canaries. In 1949 the southern volcano on the island erupted. During the eruption an enormous crack appeared across one side of the volcano, as the western half slipped a few metres towards the Atlantic before stopping in its tracks. Although the volcano presents no danger while it is quiescent, scientists believe the western flank will give way completely during some future eruption on the summit of the volcano. In other words, any time in the next few thousand years a huge section of southern La Palma, weighing 500 thousand million tonnes, will fall into the Atlantic ocean.

What will happen when the volcano on La Palma collapses? Scientists predict that it will generate a wave that will be almost inconceivably destructive, far bigger than anything ever witnessed in modern times. It will surge across the entire Atlantic in a matter of hours, engulfing the whole US east coast, sweeping away everything in its path up to 20km inland. Boston would be hit first, followed by New York, then all the way down the coast to Miami and the Caribbean.

^ this is the all time worst case scenario

^ this is the all time worst case scenario

...Heard Dat!! I wonder how much 500 thousand million tons is, or what we could equate that to in comparison???

[Jim Cantore]

Isnt this the second one since Katrina?

[Audrey2Katrina]

Yes I believe it was... both very minor, and ones of these magnitudes while not extremely common, are not altogether unheard of around here--just a tad unsettling in view of all the other events.
