Lake Maninjau Landslides

The southern quarter of the lake experienced much greater ground motion than the rest of the lake , and this resulted in majorlandsliding on the southern rim of the crater.  Approximately 25% of the southern rim experienced slides, burying parts of villages and displacing at least 2000 residents. Most of the slides were not extremely […]

Geotechnical Engineering Reconnaissance of the 2010 Haiti Earthquake

The earthquake epicenter was located immediately west of the city of Port-au-Prince, and the damage induced by this event was extreme. It is estimated that over 200,000 people were killed during the earthquake, and several hundred thousand injured. A strike-slip Mw = 7 event that affects ground near the margins of a bay represents a […]
