Bartholomew, "Factors influencing the distribution of debris avalanches associated with the Hurricane Camille in Nelson County, Virginia", Landslide processes of the eastern United States and Puerto Rico, Arthur P. Schultz, Randall W. Jibson.   USGS mapping of landslide density for failures triggered by Hurricane Maria in Puerto Rico. The USGS has now posted online a map of the landslide density for failures triggered by Hurricane Maria in Puerto Rico in September , following on from their earlier work on landslide mapping has been undertaken using high resolution satellite images. Shallow soil slips, earth and debris slides appear to be a primary mechanism of hillslope denudation in the rainforest of eastern Puerto Rico. Annual rainfall in excess of 4, mm, and thick sequences (up to 20 m) of residual soils (saprolite) combine to produce these landslides. Shear strength testing and observatons of tension cracks indicate that landslides may start as tensile failure of Cited by: 3. The Puerto Rico floods produced the deadliest single landslide on record in North America, killing at least people in the Mameyes neighborhood of barrio Portugués Urbano in floods were the result of a westward-moving tropical wave that emerged off the coast of Africa on September The system moved into the Caribbean Sea on October 5 and produced torrential rainfall Location: Puerto Rico.

LANDSLIDES IN PUERTO RICO Introduction. The Commonwealth of Puerto Rico, a possession of the United States, lies about kilometers southeast of the U.S. mainland at the eastern extremity of the Greater Antilles. Puerto Rico has an area of square kilometers, about 70 to 80 percent of which is hilly or mountainous. Landslides occur in all geographic regions of the nation in response to a wide range of conditions and triggering processes that include storms, earthquakes, and human activities. Landslides in the United States result in an estimated average of 25 to 50 deaths annually and cost $1 to 3 billion per year. An average of people are killed by landslides each year in the United States. The worldwide death toll per year due to landslides is in the thousands. Most landslide fatalities are from rock falls, debris flows, or volcanic debris flows (called lahars). Twenty-three people were killed, at least injured, and more than homes were. The risk of landslides during intense or prolonged rainfall is high in steeply sloping areas such as the municipality of Ponce, where 56 percent of the square-kilometer municipality has slopes 10 degrees or greater. These are areas where the possibility of landsliding increases when triggering conditions such as heavy rainfall or excavation and construction occur.

Bras Received: 30 July /Accepted: 10 February Springer-Verlag Abstract Landslides are a major geologic hazard with estimated tens of deaths and $1–2 billion in economic losses per year in the US by: This article lists notable tsunamis, which are sorted by the date and location that the tsunami occurred.. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, but are a worldwide natural are possible wherever large bodies of water are found, including inland lakes.

The map was compiled using days of imagery captured from satellites that passed over the island.
