Was the 2010 Haiti Earthquake triggered by deforestation and the 2008 hurricanes?

Major earthquakes occur when the stress on rocks between two tectonic plates reaches a critical breaking point, allowing the earth to move along the connecting fault. While the slow creep of the tectonic plates makes earthquakes inevitable along major faults, the timing and exact location of the quake epicenter can be influenced by outside forces pushing down on Earth's crust. For example, the sloshing of water into the Eastern Pacific during El Niño events has been linked to magnitude 4, 5, and 6 earthquakes on the seafloor below, due to the extra weight of water caused by local sea level rise. Sea level rise due to rapid melting of Earth's ice sheets could also potentially trigger earthquakes, though it is unknown at what melting rate such an effect might become significant.


Figure 1. Google Earth image of Haiti taken November 8, 2010, showing the capital of Port-Au-Prince and the mountainous region to its west where the epicenter of the 2010 earthquake was. Note the brown color of the mountains, where all the vegetation has been stripped off, leaving bare slopes subject to extreme erosion. Heavy rains in recent years have washed huge amounts of sediment into the Leogane Delta to the north.

High amounts of sediments have been eroded from Haiti's deforested mountains and deposited in the Delta. Recent expansion of the river channel due to runoff from Hurricane Tomas' rains is apparent in the 2010 image. Image credit: Google Earth, Digital Globe, GeoEye.

At last week's American Geophysical Union (AGU) meeting last week in San Francisco, Shimon Wdowinsky of the University of Miami proposed a different method whereby unusual strains on the crust might trigger an earthquake. In a talk titled, Triggering of the 2010 Haiti earthquake by hurricanes and possibly deforestation , Wdowinsky studied the stresses on Earth's crust over the epicenter of the mighty January 12, 2010 Haiti earthquake that killed over 200,000 people. This quake was centered in a mountainous area of southwest Haiti that has undergone severe deforestation—over 98% of the trees have been felled on the mountain in recent decades, allowing extreme erosion to occur during Haiti's frequent heavy rainfall events. Since 1975, the erosion rate in these mountains has been 6 mm/year, compared to the typical erosion rate of less than 1 mm/yr in forested tropical mountains. Satellite imagery (Figure 2) reveals that the eroded material has built up significantly in the Leogane Delta to the north of the earthquake's epicenter. In the 2008 hurricane season, four storms--Fay, Gustav, Hanna, and Ike--dumped heavy rains on the impoverished nation. The bare, rugged hillsides let flood waters rampage into large areas of the country, killing over 1,000, destroying 22,702 homes, and damaging another 84,625. About 800,000 people were affected--8% of Haiti's total population. The flood wiped out 70% of Haiti's crops, resulting in dozens of deaths of children due to malnutrition in the months following the storms. Damage was estimated at over $1 billion, the costliest natural disaster in Haitian history. The damage amounted to over 5% of the country's $17 billion GDP, a staggering blow for a nation so poor. Tragically, the hurricanes of 2008 may have set up Haiti for an ever larger disaster. Wdowinsky computed that the amount of mass eroded away from the mountains over the epicenter of the 2010 earthquake was sufficient to cause crustal strains capable of causing a vertically-oriented slippage along a previously unknown fault. This type of motion is quite unusual in this region, as most quakes in Haiti tend to be of the strike-slip variety, where the tectonic plates slide horizontally past each other. The fact that the 2010 Haiti quake occurred along a vertically moving fault lends support to the idea that the slippage was triggered due to mass stripped off the mountains by erosion over the epicenter, combined with the extra weight of the extra sediment deposited in the Leogane Delta clamping down on the northern portion of the fault. Wdowinsky gave two other examples in Taiwan where earthquakes followed several months after the passage of tropical cyclones that dumped heavy rains over mountainous regions. His theory of tropical cyclone-triggered quakes deserves consideration, and provides another excellent reason to curb excessive deforestation!

It is definitely time for many over the Eastern U.S. to start paying attention to the potential of a very major winter storm developing this Christmas weekend. The latest 12z Euro is depicting a major system to spin up along the Gulf Coast and intensify as it makes it trek up the East Coast. This is a very dynamical system potentially and all of a sudden, if this should verify, this system has the makings possibly of becoming as significant of a winter storm as we have not seen in quite some time.

09 Nov 09 The Solar Cell USB Sun Drive

It may look like an over-priced flash drive at $23 but you have to give technology some allowance in making it happen. This solar cell USB key called the Sun Drive comes in various capacities (2.1G, 2.2G, 2.3G and 2.4G). As you would guess, it solicits its power from the sun (solar power) which should become an ideal alternative for mobile phone power (100 minutes of talk time) or as a power source for MP3 players (35 hours). It may seem bulky but this is because of the solar cell and the battery. Overall, this is should be a handy gadget, especially for the ones who have all kinds of gadgets on the go.

A more apt question to ask would be:

Travel chaos in Europe; more blizzards forecast
Transportation grinds to a virtual halt in many parts of Europe as tens of thousands of travelers are stranded at airports and train and bus trips are canceled. More bad weather is forecast.
December 20, 2010|By Kim Willsher, Los Angeles Times

Reporting from Paris — Large portions of Europe remained paralyzed Sunday as a new wave of heavy snow and ice swept the continent as far south as Italy, shutting down airports, highways and train routes.

Though a white Christmas appeared to be in the cards for much of Northern Europe, the prospect brought little cheer to travelers struggling to reach home or vacation destinations.

The Eiffel Tower was closed because of the snow.

The French national rail company SNCF said trains were running but warned of severe speed restrictions and delays for the estimated 2.4 million travelers expected at stations over the weekend.

The French meteorological office warned of another "intense spell of snow," with up to 8 inches in some regions, that it said would be considerably heavier than in previous days. It also warned that temperatures would drop again overnight, causing roads and pavement to freeze over.

By Sunday evening, Frankfurt airport, Germany's busiest, had canceled nearly 600 of the scheduled 1,300 flights. On Saturday, police were called when it appeared that some frustrated passengers might become violent, but the atmosphere was said to have calmed on Sunday.

Airport authorities drafted staffers to dress as angels and walk the terminals in the hope they would calm travelers' anger.

"Our timetables are in utter shambles," an airport representative told the German news agency DPA.

Many at Frankfurt and airports in London, Paris, Amsterdam and Brussels spent the night on terminal floors because hotels were full.

Snow fell in Rome and even on Capri, the island in the Bay of Naples, according to the Italian news agency ANSA. High-speed train service among Milan, Rome and Florence was canceled, leaving 5,000 passengers stranded.

The travel disruptions also affected Switzerland, Denmark, Sweden, Bulgaria and Croatia.

So far, with a mean (average of maxima and minima) CET of -0.4C, December 2010 is the 3rd coldest December since records began in 1659.

But with some models trending milder in the period from Christmas to New Year, it's probably safer to say that December 2010 is likely to be the 7th coldest December since records began in 1659, and the coldest since 1890 (itself the coldest on record), beating the coldest December of the last century, which was 1981 with a CET of +0.3C.

It's universally accepted that the impact of a large bolide 65 million years ago both created the Chixculub crater and triggered the extinction of dinosaurs and much other life.

To state that "urban heating" has changed weather patterns a bit in populated areas may be true, but that's only a small part of the whole story. The increased amounts of CO2 we've been pumping into the atmosphere for decades now is altering the climate globally, most evident in rapid warming.

Twist and turn, tap the AGW dance all you want.

I am not the one who is proposing a new view...you are.

I do not have any homework to do because you and your AGW lemming friends have yet to give us free and unfettered access to the information and methodology that would allow us to decide one way or the other.

It is YOUR responsibility to prove your position is the correct one. The fact that I do not accept your assertions is your problem, not mine. I owe you not one bit of anything.

You have yet to address the problems with the fact that there is no protocol for making sure the information true and correct.

You do not address the fact that all of the information and the computer assumptions, is not freely available for all to see for themselves. Not to mention the scientists themselves who falsify the data or are duped into believing it to be true.

Apparently, the information is not freely available because it is totally and completely fraudulent, why else hide it.




for a brief moment, i shall seriously reply so you have a clue who you are dealing with.

i am not an AGW proponent. I am of mixed beliefs, and have stayed any convictions. I hedge my bets by supporting actions that would combat AGW should it be true, and I am of sound an open mind to digest all factors that may prove true contrary to AGW beliefs. I am on the lookout for scientific information. I don't think you know what that actually means.

That is why on a previous post some days back, I stated that I fall somewhere between Atmoaggie's scientific-based skepticism, and Neapolitan's scientific-based concerns. I find that both of these bloggers epitomize effective discourse over the MASSIVE amounts of data available.

But then there's you, denying a warming climate, accusing all climate scientists of lying to get money, and accusing people here of being mindless sheep. Never have you backed up your claims with supporting evidence. Still you refuse to answer the call to prove that climate scientists are corrupt money grubbers.

You just don't get that I am coming at you without being an AGW proponent. Every attempt to counter my posts in such a light is another misstep by you. So answer the call for proof, once and for all, the corruption you see in the climate research community.

Now i will go back to mirroring your method of finger pointed comments... at least until you support your claim about the money-based motivations of fraudulent climate research. That is the only item I have, and will continue to address with you. If we can put that to rest, maybe, just maybe, we can enter a discussion about the results of the data and accompanying research.

To: U.S. West Coast, Alaska, and British Columbia coastal regions
From: NOAA/NWS/West Coast and Alaska Tsunami Warning Center
Subject: Tsunami Information Statement #1 issued 12/21/2010 at 9:32AM PST

A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.

Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.

At 9:20 AM Pacific Standard Time on December 21, an earthquake with preliminary magnitude 7.4 occurred in the Bonin Islands, Japan region . (Refer to the United States Geological Survey for official earthquake parameters.)

Pacific coastal regions outside California, Oregon, Washington, British Columbia, and Alaska should refer to the Pacific Tsunami Warning Center messages for information on the event.

This will be the only statement issued for this event by the West Coast/Alaska Tsunami Warning Center unless conditions warrant. See the WCATWC web site for basic tsunami information, safety rules, and a tsunami travel time map and table. (NOTE: Travel time maps and tables indicate forecasted times only, not that a wave was generated.)

Absolutely positively no way you can prove what you just stated regarding the cause of the earth going through a warming trend. None. At the most, you can skew the data, tailor the numbers, do whatever it takes to continue to push forward a bogus agenda: AGW

Give it 15 -20 years and you'll all be talking off the next ice age just like the folks in the wake of the 1970's, 80's winters. It's a hot topic right now, sure. But a trendy one, governed by falsifying data to one's likings to make wild and frivolous accusations that man is the cause of a multi-billion year old planet's rapid demise.

Keep following the $$


I love the classic agw argument that pro GW folk are in it for money. Two things are terribly wrong with that claim. One, they never provide evidence. Ever. And two, if anything, the money is in agw. Pro GW folk are pushing towards what would end the oil industry--the richest of all industries.

Thirdly, The debate isn't't if we are warming, its what is causing the warming. Now, do you believe in the greenhouse gas theory? Do you recognize that humans are adding greenhouse gases to the air?

If you said no to either of the above questions, you're wrong. If you said yes to the questions then you would recognize humans play a role in the current warming period. To what extent we will never know.
