1918 San Fermín Earthquake
The 1918 San Fermín earthquake, also known as the Puerto Rico earthquake of 1918, struck the island of Puerto Rico at on October 11. The earthquake measured 7.1 on the moment magnitude scale and IX (''Violent'') on the Mercalli intensity scale. The mainshock epicenter occurred off the northwestern coast of the island, somewhere along the Puerto Rico Trench. The earthquake triggered a tsunami with waves measured that swept the west coast of the island. The combined effects of the earthquake and tsunami made it one of the worst natural disasters that have struck the island. The losses resulting from the disaster were approximately 76–118 casualties and $4–29 million in property damage. Earthquake The epicenter of the 1918 San Fermín earthquake was located in the Mona Passage off the northwestern coast of the island. The strongest ground shaking has been estimated at intensity IX on the Mercalli intensity scale. The resulting tsunami affected primarily the west coast towns ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isabela, Puerto Rico
Isabela () is a town and municipality of Puerto Rico located in the north-western region of the island, north of San Sebastián; west of Quebradillas; and east of Aguadilla and Moca. It is named in honor of Isabella I of Castile. Isabela is spread over 13 barrios and Isabela Pueblo, which is the downtown area and administrative center. It is a principal part of the Aguadilla-Isabela-San Sebastián Metropolitan Statistical Area. Nicknames The town is known as the ''Jardín del Noroeste'' ("Garden of the Northwest"), because of the many wild flowers in its landscape. It is also known as ''El Pueblo de los Quesitos de Hoja'' ("Town of Leaf Cheeses") for its production of a typical fresh white cheese wrapped in banana plant leaves, reputed to be the best. It is also known as la ''Ciudad de los Gallitos'' or the "City of the Fighting Cocks." Since the 18th century, cock fighting was very common throughout the island, and the town became well known for the quality of its fightin ...

International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collecti ...

List Of Earthquakes In Puerto Rico
Puerto Rico and the Virgin Islands lie at the boundary between the Caribbean and North American plates, making these territories prone to earthquakes. This is a highly active seismic region both surrounded and traversed by numerous fault lines; to the north, the North American plate subducts into the Caribbean plate, while a number of transform fault lines cross the main island of Puerto Rico diagonally from southeast to northeast. Puerto Rico and the Virgin Islands are also located on a microplate that is continuously being trampled by the subduction zone to the north. Puerto Rico is constantly prone to experiencing major earthquakes, superior to 7.0, at any moment. History The region has been seismically active since ancient times. The Great Northern and Great Southern fault zones that cross the main island of Puerto Rico laterally have been active since the Eocene epoch. Earthquakes in the region have been recorded since the early 17th century and some of the first seismi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geology Of Puerto Rico
The Geology of Puerto Rico "can be divided into three major geologic provinces: The Cordillera Central, the Carbonate, and the Coastal Lowlands." Puerto Rico is composed of Jurassic to Eocene volcanic and plutonic rocks, which are overlain by younger Oligocene to recent carbonates and other sedimentary rocks. Most of the caverns and karst topography on the island occurs in the northern Oligocene to recent carbonates. The oldest rocks are approximately 190 million years old (Jurassic) and are located at Sierra Bermeja in the southwest part of the island. These rocks may represent part of the oceanic crust and are believed to come from the Pacific Ocean realm. During the Carboniferous period, Puerto Rico was submerged. Puerto Rico lies at the boundary between the Caribbean and North American plates. This means that it is currently being deformed by the tectonic stresses caused by the interaction of these plates. These stresses may cause earthquakes and tsunamis. These seismic ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
