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] |

Mercalli Intensity Scale
The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "" magnitude usually reported for an earthquake). While shaking is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. Deeper earthquakes also have less interaction with the surface, and their energy is spread out across a larger volume. Shaking intensity is localized, generally diminishing with distance from the earthquake's epicenter, but can be amplified in sedimentary basins and certain kinds of unconsolidated soils. Intensity scales empirically categorize the intensity of shaking based on the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1867 Virgin Islands Earthquake And Tsunami
The 1867 Virgin Islands earthquake and tsunami occurred on November 18, at 2.45 p.m. in the Anegada Trough about 20 km southwest of Saint Thomas, Danish West Indies (now U.S. Virgin Islands). The 7.5 earthquake came just 20 days after the devastating San Narciso Hurricane in the same region. Tsunamis from this earthquake were some of the highest ever recorded in the Lesser Antilles. Wave heights exceeded in some islands in the Lesser Antilles. The earthquake and tsunami resulted in no more than 50 fatalities, although casualties in the hundreds is also claimed. Tectonic setting The U.S.Virgin Islands are part of the Greater Antilles that lies parallel to the Puerto Rico Trench; an oblique subduction zone where the North American Plate is underthrusted beneath the Caribbean Plate along the Lesser Antilles subduction zone transits to strike-slip along the Septentrional-Oriente fault zone. Because of this transition, the overriding Caribbean Plate begins to extend, and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...
