Blunt Force Trauma

Weather related....In case you missed it, U.S. drought is growing in the southeast. 'Exceptional' drought has almost engulfed an entire state and one half of another.



A whole lot of smoke is issuing from vast fires in Idaho and Montana:


And the Dakotas:


I saw the smoke high up at sunset last evening here in Western Massachusetts.

Today, we are having very strong wind gusts up here, which we always seem to get when when hurricanes are in the Gulf of Mexico. They will send the smoke northward today, I would guess.

It makes sense that hurricanes can instigate earthquakes. In the ocean, they cause tidal surges, and it is established that even water pent up in new dams can cause them. I think they could do the same on land. For one thing, it is now known that hurricanes spawn many tornadoes, and tornadoes do far more than just rip things up. They produce powerful "ground thumping" that is easily detected on seismographs. I was in one once, in '89, I think. I was in a car, and it seemed to "jump around" from the repetitive blasts. All the trees around me were down, I noticed, when the water and mist vanished. (I wasn't under a bridge, but come to think of it, I will be more careful about hiding under bridges in tornadoes now!)

I would guess that even powerful thunderbolts could cause earthquakes. The crystal structure of rocks is presumably very uniform, and many such stones are subject to piezoelectric effects; so they expand or contract when hit with strong electrical discharges. From what I hear, though, most earthquakes are caused by the gravitational distortion ("tidal effect" of three feet or more across the globe) produced when the moon is near the earth and in conjunction with the sun (a solar eclipse is the worst case).


"...the whole planet seems to be convulsing again right now on the meteorologial as well as the geological level. And this is no coincidence: our planet's systems are interlocked in amazing ways."

Yes, and the interlocks are also going to show up in earthquakes caused by not only hurricanes but also melting glaciers. Only a few writers and scientists that I'm aware of have begun to postulate that global warming will--through the interconnectedness of Earth's environment--cause more and larger earthquakes through glacial thawing. The melting of glaciers and ice-packs significantly alters the pressure on the Earth's crust, lessening it where a glacier melts. Ice is comparatively heavy (about 1 ton per cubic meter if I recall correctly). With some glaciers having flow rates in the 1000s of cubic meters per second as they melt, there is a sudden and significant loss of pressure on the crust. The pressure itself isn't lost, of course, but it's transferred elsewhere, changing the dynamics and likelihood of earthquakes. Moreover, the seismic changes resulting from the altered pressure distribution may also manifest themselves in increased volcanism as well as earthquakes.

Get ready, Canada. Your comparatively timid seismic environment may be getting grumpy pretty soon.


It's the Frigging Crack of DOOOOOOM!!!

(Pob'ly is, but I know it's none of my business. I'm sure someone else will handle it.)


P.S. Here's a delicious irony for you: TVA has had to shut down one of its nuke plants temporarily because of global warming. The "cooling water" is too hot. The neocons love nukes, but the global warming they denied for years is now going to let them know who's boss on this planet.



Yeah. I saw that Daliwood. You know, Daliwood, your style is just way too, way too. I hereby nominate you for the next Gore Vidal!


Thanks, blues. I appreciate the compliment.

Do you remember Truman Capote's review of a Gore Vidal novel? -- "That's not writing; that's typing."


I haven't read a Vidal novel for 40 years, but they were great. I started reading Capote, but, if memory serves, I couldn't stand the egomania of it. I have seen a lot of artists with overwhelming ego issues, and they are the worst!


As my old stats prof never tired of telling us, "Correlation is not causation."

And, "Coincidence is not correlation."

And another one, revised and updated for the 21st century: "The plural of anecdote is not 'data'".

In Other Words... your earthquake/hurricane link will need to be much stronger for me to believe there's any 'there' there.

"A helicopter bringing aid crashed and where is the US navy? Where are they? When we lost New Orleans they were all in the Gulf of Persia! And Asia!"

Disaster relief and Search&Rescue isn't the Navy's job. For that you want the Coast Guard.

"This huge hurricane forming in the Gulf will suck up a lot of energy because there have been no storms at all this season so as the earth shifts from the Solstice to the Equinox, violent storms will bloom."

An recent Sci-Am article suggested that stronger storms will mean fewer storms, precisely because big storms suck up a lot of energy.


Gore Vidal is a vacuous old poofter.


That's Poofter to you, partner.


"I would guess that even powerful thunderbolts could cause earthquakes."

How about if everyone in North America jumped off their dining room tables at precisely the same instant? Would you expect earthquakes and tidal waves in Indonesia?

When we were pounded by twin hurricanes in 2003, the second one, Jeanne, caused an earthquake that I felt here in Vero Beach Florida as it came ashore. It wasn't enough to rattle dishes (the wind could have done that!) but was a steady, heavy vibration with a rumble I could hear over the storm winds which were really wailing at that time. Other felt it but not one person I talked to had ever heard of such a thing. I researched it and discover that we really did have an earthquake and a Cat 3 storm at the same time.
