The Haiti Earthquake - Visiting the Epicenter in Leogone -- Total Devestation

Today we began our second phase of Haitian medical relief by heading out of Port Au Prince and into the surrounding countryside in search of communities that are in need of medical clinics and triage. Today we went southwest about 30 kilometers to Gressier and Leogane, the reported epicenter of the January 12 quake. The destruction in Leogane was nothing short of mind-blowing. Wed conservatively estimate that at least 80-90% of all buildings, houses and other structures in Leogane were destroyed. In the attached video, you will see some of the destruction of downtown, including a huge pile of pulverized concrete. This huge pile was in fact the historic Catholic Church built sometime on the 18th century. It is nothing more than rock and dust today. Dr. Joe Markee of Vancouver, WA who was leading our outreach is a former resident of Leogane. He was shocked and saddened. See more on my blog at: orhospitals.wordpress.com
