NPR: Geologists working in Haiti say they’ve been able to trace the exact location of the earthquake fault that gave way on 12 January and killed more than 200,000 people. They’ve also discovered that decades of deforestation in Haiti actually contributed to the earthquake’s toll along the coastline by allowing sediment to drain from the mountains and form a flood plain which people built on. This loose soil liquified in the earthquake, causing loss of life. Related news picksThe Haiti earthquakeHaiti likely to suffer more aftershock tremorsMore science from the Haiti earthquake
