Constrruction the island of Hispaniola, which comprises the Dominican Republic and Haiti, the Caribbean-North American boundary stresses are expressed in numerous strike-slip faults, including the Enriquillo and Septentrional, which are relatively long and roughly parallel.

Rebuilding Haiti will be a tough haul. Prentice, a geologist with the geological survey in Menlo Park. Stress to joints, window and door frames were effected and cracking on walls on lower floor.

Et je fais mienne cette affirmation de Jean Rostand: There are several outer buildings that seemed to have suffered minor damages, with one new building under construction pictured that appeared intact. That raises the possibility that the Jan. Along the boundaries, the relative eastward movement of the Caribbean plate, at the rate of less than an inch a year, creates strike-slip faults, shallow fissures whose sides slide in relation to one another in an earthquake.

Researchers said that more study was needed on the Septentrional and Enriquillo faults and elsewhere in the Caribbean, and that governments needed to prepare better for the inevitable. After the tsunami in Indonesia, recent mudslides in Columbia, earthquakes in Mexico, in rural China and in Nicaragua—not to mention the devastation of Hurricane Katrina on the Gulf Coast of the United States—a template for rebuilding in poor countries has begun to take shape.

Although the results are preliminary, the work shows that stresses have increased just west of the segment and just east, within three miles of Port-au-Prince. Ces abris solides pourraient recevoir chacun, je l’imagine, plusieurs dizaines de familles The following bureaus, offices, and ministries were surveyed: Major institutions—the national cathedral, the presidential palace—lie toppled.

All those things have put the whole country on edge. Il fait pages. But experts in the field of urban planning are already thinking about ways to build a better Port-au-Prince. January 27, An article on Tuesday about seismic hazards in the Caribbean referred incorrectly to the Septentrional fault, where some experts had thought an earthquake might first occur on the island of Hispaniola.

Par Michel CorbeilLe Soleil. Liens vers cet article Envoyer par e-mail BlogThis! Mann said he was on Jamaican radio programs in the past two weeks to discuss the hazards. But in other places around the Caribbean, research money has been hard to come by. Haiti, for example, has no seismometers, meaning there has been no way to measure all the small tremors that might help characterize the Enriquillo fault. The New York Times To scientists who study seismic hazards in the Caribbean, there was no surprise in the magnitude 7 earthquake that devastated the Haitian capital, Port-au-Prince, two weeks ago.

And one building, the Ministry for Youth and Sport appeared to have suffered only minimal damages. Wikipedia Commons12 mars The fault that ruptured violently on Jan.

The State Department has yet to reach out. Xntilles for Humanity will soon be on the ground, and Earthspark, a company promoting solar power in developing countries, plans to send over 50, solar lamps, mobile chargers, and flashlights to help in the rescue effort and lay tracks for a renewable energy revolution constructlon Haiti.

Much of what is known about the seismic activity around Port-au-Prince has been gleaned from historical accounts of previous quakes. Si vous individudlles allez droit au but, cliquez sur: Countless other homes, stores, office buildings and more churches have been reduced to rubble. Researchers have relied on a network of 35 benchmarks to measure fault movement.


Of the 22 structures surveyed: There are already signs that the Haitian quake has prompted concern elsewhere in the region, at least among the general population. Mann and others were planning a trip to Haiti to make more accurate measurements for their stress calculations, and to install devices to monitor the fault zone continuously for a year or more. Last Thursday, the geological survey issued a statement estimating that there was a 3 percent likelihood maisos a 7 magnitude aftershock in the next 30 days, and a 25 percent chance of one of magnitude 6.

Additionally, there are more than one thousand internally displaced persons consteuction on the property. But the intensity and frequency of those aftershocks have followed the patterns of other earthquakes, he said. Il y a aussi de bons ouvrages. While there were workers on the premise egress into the building was limited. Researchers have estimated that maizons rupture along that segment — and again, they have no idea when one might occur — could result in a magnitude 7.

Solution en matière d’habitation. Du sur mesure à votre mesure.

Except, perhaps, in where on the island of Hispaniola it occurred. Unable to gain access because of rubble to egress areas. Debris will need to be cleared before new structures can take their place. A long segment in the Dominican Republic, not the entire fault, has gone without a quake for years.
