Catastophic earthquake rocks Haiti
After making it through the hurricane season of 2009 without a scratch, Haiti's terrible earthquake of January 12, 2010 has brought a catastrophe of unfathomable magnitude to the impoverished people of Haiti, the poorest nation in the Western Hemisphere. The magnitude 7.0 earthquake was centered just ten miles southwest of the capital of Port-au-Prince, at a shallow depth of 6.2 miles, according to the U.S. Geological Survey. The shock occurred in the boundary region separating the Caribbean plate and the North America plate. The two plates slide past each other at a rate of about 0.8 inches (20 mm) per year, with the Caribbean plate moving eastward with respect to the North America plate. The fault that produced the quake is called the Enriquillo-Plaintain Garden fault system, and last produced a major earthquake in 1860. According to the USGS (Figure 1), 238,000 people near the quake's epicenter experienced violent to extreme shaking, capable of causing very heavy damage. A further 3.2 million people experienced very strong to severe shaking, capable of causing moderate to heavy damage. Another 1.3 million people experienced strong shaking, capable of causing moderate damage. Haiti's total population is just 9 million, so half the country's population lived in areas that received moderate to very heavy damage from the earthquake. The quake did not generate a large tsunami, though a tsunami of 5 inches (12 cm) was recorded at Santo Domingo in the Dominican Republic. It is possible that a local scale, moderately destructive tsunami was generated close to the shores of Port-au-Prince.

One of the greatest natural disasters in Haitian history
In many ways, the hurricane season of 2008 was the cruelest ever experienced in Haiti. Four storms--Fay, Gustav, Hanna, and Ike--dumped heavy rains on the impoverished nation. The rugged hillsides, stripped bare of 98% of their forest cover thanks to deforestation, let flood waters rampage into large areas of the country. Particularly hard-hit was Gonaives, the fourth largest city. According to reliefweb.org, Haiti suffered 793 killed, with 310 missing and another 593 injured. The hurricanes destroyed 22,702 homes and damaged 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 massive blow for a nation so poor.
Thus when it became clear that the hurricane season of 2009 would spare Haiti further misery, I was delighted that our suffering neighbors would get a chance to regroup and rebuild. But the unimaginable destruction wrought by yesterday's quake is a staggering blow for a nation so poor. When the damage is tallied and compared to Haiti's GDP of $17 billion, the earthquake of 2010 could well prove to be one of the most devastating disasters in world history. Further, Haiti's population is only 9 million, and the number of people killed, injured, and made homeless will make up a huge fraction of the Haitian population.

Haitian earthquake history
The western portion of Haiti where yesterday's quake occurred is in a relatively low seismic risk region of the Caribbean (Figure 2). Large quakes are uncommon in Haiti. The worst quake in Haitian history was probably the May 7, 1842 magnitude 7.7 Cap-Haitien earthquake. This massive tremor hit a fault on the northern portion of the island, killing 10,000; three hundred of these deaths were from a large tsunami generated by the quake. One of the largest cities in Haiti--Cap-Haitien, with a population of 60,000--was destroyed, with the loss of 6,000 lives.
Caribbean earthquake history
The Eastern Caribbean is no stranger to devastating earthquakes. The Caribbean Plate slides against the North American Plate along a line running through most of the islands in the Eastern Caribbean, generating frequent earthquakes. According to the University of the West Indies Seismic Research Center, the most severe quake to hit the region occurred on February 8, 1843, when a tremor estimated at 8.0 - 8.5 on the Richter Scale struck the Lesser Antilles Islands. Heavy damage was reported from St. Maarten to Dominica. In Antigua, the English Harbour sank. In Point-a-Pitre, Guadeloupe, all masonry construction was destroyed, and a fire broke out that burned down the remaining wooden structures. One third of the population, estimated at 4,000 - 6,000 persons, perished. The event was felt as far south as Caracas and British Guiana and was even felt 2,000 km away in Washington D.C., Vermont, and Charlestown, South Carolina. The largest Eastern Caribbean earthquake recorded by modern seismographs was the El Cibao earthquake in the Dominican Republic in 1946. The earthquake was of magnitude 8.1 and generated a tsunami which caused 75 deaths and rendered 20,000 homeless.

Lambi Fund of Haiti and Portlight mobilize to help out
For the past five years, I've been a contributor and booster of the Lambi Fund of Haiti, a charity that is very active in promoting reforestation efforts, use of alternative fuels, and infrastructure improvements at a grass-roots level in Haiti. I've developed a great respect for the work they do in the country, and have gotten to know Karen Ashmore, the executive director of the charity, and have written articles for their newsletter. Karen wrote me last night with this plea for help: "Most buildings in Port-Au-Prince have been damaged or have collapsed, which would include homes of staff and families we work with, as well as the grain mills, sugar cane mills, and sites for community economic development. And cisterns and latrines we have supported for safe drinking water and sanitation. Major rebuilding effort needed. Please post on your blog".
To help the Lambi Fund rebuild what was destroyed, visit their on-line donation page. Keep in mind that they are second responders--their aim is not to provide for the immediate needs of food, water, and medicine, but to rebuild the Haitian infrastructure and economy.
Portlight.org, the remarkable disaster-relief charity that has sprung up from the hard work and dedication of many members of the wunderground.com community, has also mobilized to help out the victims of the Haitian earthquake. As Paul Timmons writes in the Portlight blog this morning,
Portlight's focus in this is going to be on people with disabilities in Haiti...providing medical equipment, shelter, and food for them...there is an article below about the treatment of this population in the best of times...and this ain't the best of times...
We have a "Go" container in Atlanta which will ship out in a few days...and an ongoing relationship with a community of Catholic sisters in Port au Prince who will be opening shelters...
Any funds we raise will be used to defray shipping costs of medical and clinical equipment...and for the purchase of food and other shelter supplies...Haiti is our neighbor...and Haitians are certainly forgotten people...people with disabilities in Haiti are frequently barely seen as human...
Anyone interested in going to Haiti to help staff one or more shelters for Haitians with disabilities please WU mail us...
So, please visit the Portlight.org blog to learn more and to donate. Portlight is acting as a first responder, to answer the immediate needs of the Haitian people for water, food, and medical equipment. Portlight is exploring ways they can work together with the Lambi Fund of Haiti to put the materials donated where they are most needed. If you're interested in sponsoring an Honor Walk to help raise funds for the Haitians, please contact Paul Timmons of Portlight, via the Portlight.org blog. Thank you.
There are two things Haiti does have going for it in the wake of this horrible tragedy. Firstly, it is not hurricane season, so the Haitians have six months to rebuild and shelter their homeless before the storms of summer arrive. There is a large mass of dry air over the Caribbean at present, so there will be dry weather for relief operations for at least the next few days. Secondly, former President Bill Clinton was appointed the UN Special Envoy to Haiti last year, and he brings an important visible face to the needs of Haiti's suffering people. A huge amount of aid will be needed for this tragedy.
My thoughts and prayers are with all the victims and relatives of those affected by the earthquake.
I'll have a new post on Friday.

I sent you both Wu-mail.
In the local S. Ontario news, I heard about a charity that helped the survivors of Hurricane Ike that is now going to Haiti in a four-man team, providing water supplies and other basic nessecities. Sounds to me a little bit like Portlight, but they did not mention the charity by name so I don't know for sure.
Here in S. Ontario, the local forecast predicts one freezing rain day this week, next week, and the week after. This usually does not happen, and I am blaming the clashing of two air masses, moisture from the warmer airmass and the cold Arctic air.
Those are great photos...
On the Drudge Report the headline says 500,000 may be dead. I am grateful to have a warm bed to sleep in tonight in Tn.
Military Preps for Broader Haiti Relief Mission
By Donna Miles
American Forces Press Service
WASHINGTON, Jan. 13, 2010 – The aircraft carrier USS Carl Vinson is headed toward earthquake-devastated Haiti and is scheduled to arrive tomorrow to provide airlift support for the disaster-response mission, the commander of U.S. Southern Command reported today. Video

Meanwhile, Air Force Gen. Douglas Fraser said, Southcom is “seriously looking” at deploying a large-deck amphibious ship with a 2,000-member Marine expeditionary unit to provide disaster response and, if required, to help maintain security.
Several other Defense Department ships and Coast Guard vessels – from small ships to destroyers to cutters -- also are headed toward Haiti, some with limited humanitarian assistance supplies and helicopters aboard.
In addition, an 82nd Airborne Division brigade and “various forces around the armed forces” have been put on alert, ready to deploy if needed to support the effort, the general said.
The actions are part of a “very robust effort” under way to ensure the military is ready to respond to requirements identified through ongoing assessments, Fraser explained during news briefings today at the Pentagon and the State Department.
“We don’t know precisely what the situation is on the ground,” he said, “so we are leaning forward to provide as much capability as quickly as we can to respond to whatever the need is when we get there.”
Meanwhile, the military is taking accountability of its own 64 troops assigned to Haiti. Most are part of the military liaison group there or support the United Nations Stabilization Mission in Haiti, Fraser said.
Fraser is leading military support to the disaster response mission, being coordinated through the U.S. Agency for International Development and State Department’s Office of Foreign Disaster Assistance.
His deputy military commander, Air Force Lt. Gen. P.K. “Ken” Keen, was on the ground in Haiti when the earthquake struck, and is providing the initial on-the-ground military command.
The initial thrust in the operation, Fraser said, is on assessing the situation on the ground to determine what’s needed and where, and to provide communications and command-and-control equipment needed to support relief efforts.
Toward that end, Southcom is deploying a 30-person team to Haiti this afternoon to support U.S. relief efforts.
Two Puerto Rico Air National Guard C-130 Hercules aircraft will deliver the team, made up of U.S. military engineers, operational planners, a command-and-control group and communication specialists. Once on the ground, they will work with U.S. Embassy personnel as well as Haitian, U.N. and international officials to assess the situation and facilitate follow-on U.S. military support.
“From practice, we've found that the assessments are critical to making sure we get the right equipment in there and make the recovery efforts and the life-supporting efforts as efficient as possible,” Fraser explained.
Meanwhile, the C-130s are transporting civilian search-and-rescue teams to Haiti, he said.
Southcom officials reported other immediate response activities:
-- A U.S. Coast Guard helicopter evacuated four critically injured U.S. Embassy staff to Naval Station Guantanamo, Cuba, hospital for further treatment earlier today;
-- Elements of the Air Force’s 1st Special Operations Wing will arrive in Haiti this afternoon to provide air traffic control capability and airfield operations at the Port-au-Prince airport; and
-- A Navy P-3 Orion aircraft took off from Comalapa, El Salvador, early this morning to conduct an aerial reconnaissance of the area affected by the earthquake.
An important initial thrust is on getting communications and command-and-control assets into Haiti to support relief operations, Fraser told reporters. He noted that the U.N. Mission’s headquarters was severely damaged during the earthquake, with much of its communications equipment lost.
As communications and other support goes to Port-au-Prince airport to restore it to full functioning, assessment teams will also evaluate the port facilities to determine if they are operational to receive incoming aid.
The USS Carl Vinson was on a training mission when it was ordered to Haiti to support the effort. It will transit through Mayport, Fla., to take on additional humanitarian support supplies and helicopters before arriving in Haiti later tomorrow, Fraser said.
The arrival of a yet-underdetermined amphibious ship, probably a couple of days after the Vinson, will provide a broader range of capability to move supplies around and provide lift capability to support the effort, he said.
While not ruling out a deployment of the hospital ship USS Comfort, Fraser said the amphibious ship could provide much of the same medical capability.
In the meantime, all available military assets remain on the table as a clearer picture begins to emerge about what’s needed, the general said.
“We're focused on the life-saving measures that we need to do there -- the assessment, the emergency response -- and then looking at what the humanitarian and disaster relief requirements are and providing international support to Haiti, to help them through this significant disaster,” he said.
Lotsa Bows heading Seast..and one BIG Flattop too.
...And since there won't be any ridge building in the Caribbean this time around, severe weather looks more likely for the Florida Peninsula(with these series of storms). A more typical El Nino feel. Slightly below average and wet(including south Florida). With nothing to impede fronts from totally plowing through the whole state of Florida, Cuba, and the Bahama's.
Edit, I did save it, great pic! :)
One can count on the Coast Guard to be first in a Big Way.
Paul has spoke with them and the routing is in works in the am.
Outstanding.
Thats awesome. I'm really loving the effort I'm seeing in just the Wunderground community alone. Lets hope this continues.
Sorry sometimes i forget that,didnt see her width.
4th fleet Pic was cool
Exactly. I'm going to be spending quite some time on Facebook sending out messages and creating a group tomorrow to get some more help and to see if I can establish any connections with local businesses or communities in Broward. I'm ready for the challenge and to dedicate myself.
Yeppars with Stars come er,..Voice one could say.
Twas long meeting u could tell he had,but them Guys soak it up and recall call it back like Love,
Dats also why they get the good china and the big bucks too..
LOL
I will be working over the next few days to try and establish connections with my college (Broward College) and possibly local businesses and communities to try and establish a fund that will be sent to Portlight. Once I have the details and get things going, I will inform everyone here on Wunderground with the info.
This and others is why this is such a great community, I am so glad to be a paying member.
but yet a necessity..
Think Port Au Prince,think Well for Haiti tonight..
Link
Will do Pat. Have a good night's rest. You deserve it. We'll talk tomorrow.
stay safe everyone
Could the surface temp have impacted/advanced a tectonic process?
this is true, but certainly this community is an exception (:
goodnight all
No, the tectonic forces have been locking up stored energy from the 'slip/slide plate" . Both plates were lcoked up, the stresses were too great, the fault ruptured, generating the 7.0 quake.
I've never read or heard about a connection between air temperatures and seismic activity, although it would be interesting to research.
Nor have I, I viewed record low water temps on the SW coast of FL in the last week and just wondered if there was any correlation with pressure on land mass with water temp that could have played a role. Kinda like a mouse trap with respect to energy potential and plate movement. In particular, small plates in a contained area. OK, I should just sleep on it. LoL
Be well all and think of / pray for, those who are in need. --
Thanks, Craig! It was a pleasure talking with you. Hopefully, your readers will get behind the Portlight mission. :)
I hope this horrible disaster becomes an opportunity for that impoverished island nation to build a better future.
