Mameyes Landslide
The 1985 Puerto Rico floods produced showers and thunderstorms across the island and the deadliest single landslide on record in North America, that killed at least 130 people in the Mameyes neighborhood of barrio Portugués Urbano in Ponce. The floods were the result of a westward-moving tropical wave that emerged off the coast of Africa on September 29. The system moved into the Caribbean Sea on October 5 and produced heavy rains across Puerto Rico, peaking at in Toro Negro State Forest. Two stations broke their 24-hour rainfall records set in 1899. The rains caused severe flooding in the southern half of Puerto Rico, which isolated towns, washed out roads, and caused rivers to exceed their banks. In addition to the deadly landslide in Mameyes, the floods washed out a bridge in Santa Isabel that killed several people. The storm system caused about $125 million in damage and 180 deaths, which prompted a presidential disaster declaration. The tropical ...

Landslide Classification
There have been known various classifications of landslides. Broad definitions include forms of mass movement (geology), mass movement that narrower definitions exclude. For example, the ''McGraw-Hill Encyclopedia of Science and Technology'' distinguishes the following types of landslides: *fall (by undercutting) *fall (by toppling) *Slump (geology), slump *rockslide *earthflow *sinkholes, mountain side *rockslide that develops into rock avalanche Influential narrower definitions restrict landslides to slumps and translational slides in rock and regolith, not involving fluidisation. This excludes falls, topples, lateral spreads, and mass flows from the definition.Varnes D. J., Slope movement types and processes. In: Schuster R. L. & Krizek R. J.

Return Period
A return period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, landslides, or river discharge flows to occur. The reciprocal value of return period is called the frequency of occurrence. It is a statistical measurement typically based on historic data over an extended period, and is used usually for risk analysis. Examples include deciding whether a project should be allowed to go forward in a zone of a certain risk or designing structures to withstand events with a certain return period. The following analysis assumes that the probability of the event occurring does not vary over time and is independent of past events. Estimating a return period Recurrence interval = :''n'' number of years on record; :''m'' is the rank of observed occurrences when arranged in descending order For floods, the event may be measured in terms of m3/s or height; for storm surges, in terms of ...
