1787 Boricua Earthquake
The 1787 Boricua earthquake struck offshore of the island of Puerto Rico on May 2. The magnitude of the earthquake was believed to have been around 8.0–8.5, however there is evidence that it was only about 6.9. The epicenter is thought to have been somewhere north of Puerto Rico, probably on the Puerto Rico Trench.Earthquake History of Puerto Rico and the Virgin Islands on Puerto Rican José Molinelli considers it "the strongest" in the seismic history of the cou ...

Puerto Rico
Puerto Rico (; abbreviated PR; tnq, Boriken, ''Borinquen''), officially the Commonwealth of Puerto Rico ( es, link=yes, Estado Libre Asociado de Puerto Rico, lit=Free Associated State of Puerto Rico), is a Caribbean island and unincorporated territory of the United States. It is located in the northeast Caribbean Sea, approximately southeast of Miami, Florida, between the Dominican Republic and the U.S. Virgin Islands, and includes the eponymous main island and several smaller islands, such as Mona, Culebra, and Vieques. It has roughly 3.2 million residents, and its capital and most populous city is San Juan. Spanish and English are the official languages of the executive branch of government, though Spanish predominates. Puerto Rico was settled by a succession of indigenous peoples beginning 2,000 to 4,000 years ago; these included the Ortoiroid, Saladoid, and Taíno. It was then colonized by Spain following the arrival of Christopher Columbus in 1493. Puerto Ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes In Puerto Rico
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes c ...

18th Century In Puerto Rico
18 (eighteen) is the natural number following 17 and preceding 19. In mathematics * Eighteen is a composite number, its divisors being 1, 2, 3, 6 and 9. Three of these divisors (3, 6 and 9) add up to 18, hence 18 is a semiperfect number. Eighteen is the first inverted square-prime of the form ''p''·''q''2. * In base ten, it is a Harshad number. * It is an abundant number, as the sum of its proper divisors is greater than itself (1+2+3+6+9 = 21). It is known to be a solitary number, despite not being coprime to this sum. * It is the number of one-sided pentominoes. * It is the only number where the sum of its written digits in base 10 (1+8 = 9) is equal to half of itself (18/2 = 9). * It is a Fine number. In science Chemistry * Eighteen is the atomic number of argon. * Group 18 of the periodic table is called the noble gases. * The 18-electron rule is a rule of thumb in transition metal chemistry for characterising and predicting the stability of metal complexes. ...

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] |
List Of Earthquakes In 1918
This is a list of earthquakes in 1918. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. A couple of major events capped a fairly active year. The two major events came within weeks of each other. The largest was a magnitude 8.3 in the Philippines in August. In early September a magnitude 8.1 struck Soviet Russia, Russia. The deadliest event occurred in February in Republic of China (1912–1949), China when a magnitude 7.3 caused 2,000 deaths. Overall By death toll * Note: At least 10 casualties By magnitude * Note: At least 7.0 magnitude Notable events January February April May June July August September October November December References {{Earthqu ...

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 ...
