Massive Sahara desert dust plume drifting toward the United States

Each summer massive plumes of dust traverse the atmosphere above the tropical Atlantic Ocean, traveling 5,000 miles from the Sahara desert in northern Africa all the way to the southern United States.

While summer dust plumes are a common occurrence, the one sailing through the Caribbean right now is generating quite the buzz. That's because it appears to be one of the most extreme in recent memory and it's heading for the southeastern states.

On satellite images from space, dust typically appears somewhat subtle and faint, but this plume can be seen as clear as day. The picture below was taken on Sunday from the International Space Station. "We flew over this Saharan dust plume today in the west central Atlantic. Amazing how large an area it covers!" astronaut Doug Hurley tweeted.

. . . .

Over the next few days the thickest of the dust layer will stay south of Florida, over Cuba. By late this week it will overspread Texas and the rest of the Southeast, making for hazy skies and colorful sunrises and sunsets.

If this did happen the predictions are that the tsunami waves would be much smaller chowder66 Jun 2020 #5
That would still take out most of the South East and the Eastern cities. haele Jun 2020 #6

What the hell else can happen???
I swear we are having the Plagues of Egypt!

Locusts. Sahara relocating. COVID. Giant toxic frogs in Florida. Flooding in Michigan. June snows in the upper midwest. 100 degrees in the Arctic circle And of course Mango Menace and his minions

Have we had any major tornados yet? However, I read that the dust cloud will reduce the possibility of hurricanes. Red tide anywhere?

All we need now is for the New Madrid Fault to shift and destroy everything from St Louis to well past Memphis.

If the Cumbra Vieja volcano goes off, or causes a major quake in the Canary Islands that ruptures the La Palma rocks formation, there can be a Tsunami the size of the 1700 Cascadia slip that can result in waves hitting the East coast of North, Central and South America, Europe, and Western Africa that will measure between 100 and 300 meters depending of the topography and directional aspect of the slip.
There would be only a few hours warning, and the waves could easily run up and reach inland a couple hundred miles at a significant height.

No country would escape the damage it would cause.
Pretty much a civilization destroying event.

10 meters is over 30 ft, and if you watched the film from the Japanese Tsunami, that would be an equivalent level from a cycle of waves that were relatively constrained in the amount of impact.
Worst damage from La Palma would be to the Caribbean and Europe. We would still have significant and pretty much irreparable damage in the major cities and along the rivers and bays that have an Atlantic outlet, not to mention the loss of life.
You can build for earthquake and to some degree for a hurricane. It's not so easy to build for a tsunami, especially since a lot of our infrastructure and Eastern coastal cities are built on fill that easily liquifies, undermining the foundations.
