Analysis of the seismic origin of landslides: Examples from the New Madrid seismic zone Analysis of the seismic origin of landslides: Examples from the New Madrid seismic zone

By analyzing two landslides in the New Madrid seismic zone, we develop an approach for judging if a landslide or group of landslides of unknown origin was more likely to have formed as a result of earthquake shaking or in aseismic conditions. The two landslides analyzed are representative of two groups of land-slides that previous research on the geomorphology and regional distribution...

Landslides triggered by Hurricane Hugo in eastern Puerto Rico, September 1989 Landslides triggered by Hurricane Hugo in eastern Puerto Rico, September 1989

On the morning of September 18, 1989, a category-four hurricane struck eastern Puerto Rico with a sustained wind speed in excess of 46 m/s. The 24-h rainfall accumulation from the hurricane ranged from 100 to 339 mm. Average rainfall intensities ranging from 34 to 39 mm/h were calculated for 4 and 6 h periods, respectively, at a rain gage equipped with satellite telemetry, and at an...

The National Landslide Information Center; data to reduce landslide damage The National Landslide Information Center; data to reduce landslide damage

Almost every day a landslide disasters occurs somewhere in the world. Nearly any time there is heavy rainfall, an earthquake, a volcanic eruption, strong wave action on a shoreline, or some ill-considered alteration of sloping land by humans, landslides occur. In a world of persistent and increasing construction on and occupation of hillslopes, canyons, and coastal bluffs, landslides are...
