Why Have There Been So Many Geological Catastrophes Lately?
There haven't been.
BY JOSHUA KEATING | APRIL 19, 2010

These days, you don't have to be a conspiracy theorist or religious fanatic to wonder whether there's something strange going on with the Earth. Major earthquakes in Haiti, Chile, and China have killed thousands, and a cloud of volcanic ash has grounded flights across Europe. This past weekend also saw deadly quakes in Afghanistan, Papua New Guinea, and the Dominican Republic. So is the Earth going through a period of especially high geological activity?

No, we're just paying more attention. 2010 is actually shaping up to be a perfectly average year for quakes. According to the U.S. Geological Survey, since 1900 the Earth has experienced an average of 16 major quakes -- magnitude 7.0 or higher -- per year. In the first four months of 2010, there have been six. So though this will likely be a worse year than 1986, when there were only six major quakes total, it's unlikely to be as bad as 1943, when there were 32. And while major earthquakes like the ones in Haiti and Chile typically cause numerous aftershocks, scientists don't think that they are directly causing each other.

So why does it seem like this has been a particularly bad year? It likely has something to do with increased media coverage. This weekend's quake off the coast of the Dominican Republic is thought to have killed only three people and probably wouldn't have garnered much international attention if not for the catastrophic temblor that struck nearby Haiti in January.

But while earthquakes haven't become more frequent, they are getting more deadly. Earthquakes killed 650,000 people in the last decade, more than any other decade in history. Around 250,000 have already died this year. This is likely because of the expansion of urban areas in fault zones. China's Qinghai province has experienced 53 magnitude 5.0 or higher quakes since 2001, but it wasn't until one struck near the population center in Yushu that the casualty numbers exploded.

As for volcanoes, while the Eyjafjallajokull eruption may be causing chaos on the continent, it's not all that unusual for Iceland, which sits right on top of the Mid-Atlantic Ridge fault line and boasts 130 volcanoes of various levels of activity. This month's eruption is mild compared with the 1783 Laki eruption which caused a famine that wiped out a quarter of Iceland's population and altered climate patterns in Northern Europe for years. Obviously, there were no jets to worry about back then.

Eyjafjallajokull may be no Mount Pinatubo, whose powerful 1991 eruption had wide-ranging effects on the Earth's climate, but its ash has been especially disruptive because the height of its plume, about 20,000 to 30,000 feet, is high enough to get caught in prevailing winds and spread over a large area.

It's also been well known for some time that jets and volcanic ash are not a good combination. Since an eruption from Alaska's Mount Redoubt nearly took down a KLM 747 in 1989, the U.S. Geological Survey has kept close tabs on the volcanoes of the Aleutian Islands, which run across a popular route for jets crossing the Pacific. The Federal Aviation Administration imposed a no-fly zone around Mt. Redoubt during an eruption as recently as last year. Of course, unlike with the Aleutians, airlines can't exactly just go around continental Europe.

Great, that blows a hole in my whole 2012 theory.

Here is the real reason and it's obvious that Miami Beach is doomed:

Attractive women who dress inappropriately cause youth to go astray and "incite extramarital sex in society, which increases earthquakes", a hardline Iranian cleric has said.

Ayatollah Kazem Sedighi told worshippers that women who wear fashionable clothes and apply make-up cause youth to "go astray" and have affairs. As a result, the country that is bound by several fault lines experienced more ‘calamities’ such as earthquakes, The Telegraph reported Tuesday.

"Many women who dress inappropriately ... cause youths to go astray, taint their chastity and incite extramarital sex in society, which increases earthquakes," Aftab-e Yazd newspaper quoted him as saying at a Tehran prayer service late last week.

"Calamities are the result of people's deeds. We have no way but conform to Islam to ward off dangers."

Every woman regardless of her religion or nationality must cover her hair and bodily contours in public and offenders face punishment.

Nearly 14 million people live in Tehran province, of which eight million live in the city that is on fault lines.

Most earthquakes happen in one area or part of world,but past several years they are happening around world,not just one area.

Wow.  Just, wow. 

I suppose they could hang out with the pseudo-Christians who believe the Earth is still flat.  that'd be a grand party!  Just without booze, chicks, dancing, or music....

Actually activity is just about normal. We are just better at measuring earthquakes and communicating.

I'm going to blame the CIA.

What part would that be??

Finally! HAARP is being put to good use!

Intiating volcanic activity as a means to counter AGW.

lmfao, someone failed basic science classes apparently.

Maybe he just didn't finish up that statement properly - thinking about plate tectonics, it would stand to reason that when there is a 'collision' in one part of the world that other areas would remain relatively quiet for some time.
Those plates are either moving quicker, or we should all figure out where they're not touching right now to anticipate one real big nasty quake somewhere.
