INTRODUCTION. The 2018 Haiti earthquake occurred on the 7th of October 2018. It was a 5.9 magnitude earthquake at 15.3km deep at sea within the Turtle canal (Canal de la Tortue ) with its epicenter located twenty kilometers west of Port-de- Paix . Eyewitnesses told CNN that two aftershocks were felt in the aftermath of the earthquake. According to the United States Geological Survey, 250,000 people within the vicinity of Port-de- paix were exposed to the earthquake with moderate damage to structures in the area (USGS, 2018). According to official reports, 10 people were killed with another 135 injured in the aftermath of the earthquake. I have selected this location because one of my friends was last seen at the near the location of the earthquake and has not been heard from since..

TECTONIC SETTING. The location of the earthquake is Canal de la Tortue . The Tortoise Canal is the upper part of a fault known as the “ Tortue Canal fault” within the Septentrional‐Oriente fault zone. It is an active tectonic fault clearly identified in the northern part of the island of Hispaniola (Haiti and the Dominican Republic). It is a fault of subduction, of East-West direction, of strong dynamism, responsible for the majority of the earthquakes occurring in the northern island part, off the north coast of the Haitian territory..

GEOLOGICAL FEATURES. The geological landscape of the location is dominated by 23 islands. It has an elevation of 1000 feet and is surrounded by two minor mountain ranges. There have been earthquakes in the region in April and July 1994 and September 2003..

CAUSE OF THE EVENT. The earthquake was caused by transpressional deformation of the North Hispanola Fault which is a major thrust zone in northern Haiti. The primary cause of the event is the movement along the Caribbean and north American plate boundary which is.

LESSONS LEARNT. Two lessons learned from the U.S. response to the Haitian earthquake demonstrate the importance of prompt and effective communications during a disaster, which can aid greatly in: (a) the timely activation of task forces; and (b) information sharing among responders..
