1982 El Salvador earthquake: The 1982 El Salvador earthquake occurred on 19 June 1982 at 00:21 local time (06:21 UTC).  It was an M 7.2 earthquake, with epicenter being located in the Pacific Ocean about 60 km southeast of San Salvador, El Salvador.  8 people were reported dead, and 1630 houses were damaged.  The earthquake triggered many landslides.  The intensity in San Salvador reached MM VII.  The most affected cities are San Salvador, Ahuachapán, Concepción de Ataco, Comasagua, San Miguel, San Pedro Nonualco, and San Juan Tepezontes.  This earthquake could be felt in Guatemala, Honduras, Nicaragua, and Costa Rica, with intensities MM V in Guatemala City, Guatemala, MM IV in Tegucigalpa, Honduras, MM V in Managua, Nicaragua, and MM III in San Jose, Costa Rica.  Near the Salvadorian coast, the Cocos Plate is subducting beneath the Caribbean Plate at the Middle America Trench.  This earthquake was an intra-slab, normal-slip subduction earthquake in the subducting plate.  The subduction zone and a local system of faults along the volcanic chain are two major sources of the earthquakes in El Salvador.  The mechanism of this earthquake had many similarities with the El Salvador earthquake of 13 January 2001.

Peromyscus: The genus Peromyscus contains the animal species commonly referred to as deer mice.  This genus of New World mice is only distantly related to the common house mouse and laboratory mouse, "Mus musculus".  Although superficially resembling "Mus musculus", "Peromyscus" species have relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring.  In reference to the coloring, the word "Peromyscus" comes from Greek words meaning "booted mouse".

Donnellyanthus: Donnellyanthus is a monotypic genus of flowering plants in the Rubiaceae family.  The genus contains only one species, viz.  Donnellyanthus deamii, which is found in Oaxaca, El Salvador, Guatemala, Honduras, and Nicaragua.

Central American Bank for Economic Integration: The Central American Bank for Economic Integration (CABEI) was founded in 1960.  It is an international institution aimed at promoting integration and development among its founding countries: Guatemala, Honduras, El Salvador, Nicaragua and Costa Rica.  It has currently two headquarters, one in Tegucigalpa (Honduras) and another one in San Salvador (El Salvador).  Besides it has national offices in every country of Central America.

Rail transport in Central America: Rail transport in Central America consists of several isolated railroad lines with freight or passenger service.  The most famous one is the Panama Canal Railway, the oldest transcontinental railroad in the world, connecting Panama City with Colón since 1855.  Other railroads in Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama were built by private and public investors mainly to facilitate the transport of local agricultural produce (bananas, coconuts, coffee) to export markets and harbors.  Their market share and profitability went into decline in the second half of the twentieth century and most lines have been decommissioned by the end of the 1990s.  As of 2010, railroads operate locally in El Salvador, Honduras, Costa Rica and Panama only; all rail transport has been suspended in Belize, Guatemala and Nicaragua.  None of the operating railways crosses national borders.

Organization of Ibero-American States: The Organization of Ibero-American States (Portuguese: "Organização dos Estados Ibero-americanos" , Spanish: "Organización de Estados Iberoamericanos" , usually abbreviated OEI), formally the Organization of Ibero-American States for Education, Science and Culture, is an international organization whose members are the Portuguese- and Spanish-speaking nations of the Americas and Europe and Equatorial Guinea in Africa.  Its purpose is to promote intergovernmental cooperation among its member nations which will aid the planning and development of regional projects in education, science, technology and the arts.  OEI members include Andorra, Argentina, Bolivia, Brazil, Colombia, Costa Rica, Cuba, Chile, Dominican Republic, Ecuador, El Salvador, Guatemala, Equatorial Guinea, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Portugal, Spain, Uruguay and Venezuela.  Its General Secretariat is located in Madrid, with regional offices in Argentina, Brazil, Colombia, El Salvador, Spain, Mexico and Peru and field offices in Chile, Honduras, Nicaragua and Paraguay.  Financing of OEI operations and programs is derived from obligatory quotas and voluntary contributions from the governments of member nations and private cultural and educational institutions and foundations.  The honorary president of the organization is King Felipe VI of Spain.

Alberto Masferrer: Vicente Alberto Masferrer Mónico, known as Alberto Masferrer, was a Salvadoran essayist, philosopher, fiction writer, and journalist, best known for the development of the philosophy of 'vitalismo'.  He was born in Alegría, Usulután formerly Tecape, Usulután on 24 July 1868.  He did not receive a formal education, instead claiming to have been educated by "the university of life," but he did travel widely, having lived in several Central American countries, as well as in Chile, New York, and several European nations.  During his public career at the Ministry of Foreign Affairs of El Salvador, he served as an ambassador of El Salvador in Argentina, Chile, Costa Rica, and Belgium, and served as a professor in Guatemala, El Salvador, Honduras, Costa Rica, Chile, and Argentina.  Having served in the government of President Arturo Araujo, he was sent into exile in Honduras by the dictatorship of Maximiliano Hernández Martínez following the uprising of 1932 known as the 1932 Salvadoran peasant massacre, dying that same year on 8 September in the city of Tegucigalpa.  (There are some uncertainties regarding his death, with some sources claiming that he died in El Salvador, though these claims are in the minority.  He was well respected during his life, having earned the praise of such major Salvadoran figures as Arturo Ambrogi, Miguel Ángel Espino, Claudia Lars, and Salarrué.

January 2001 El Salvador earthquake: The January 2001 El Salvador earthquake struck El Salvador on January 13, 2001 at 17:33:34 UTC.  The 7.6 (later estimated to be 7.7 or 7.9) quake struck with the epicenter 60 miles (100 km) SW of San Miguel, El Salvador (13.04°N 88.66°W) at a depth of 60 km.  At least 944 people were killed, 5,565 injured, 108,261 houses destroyed — with another 169,692 houses damaged — and more than 150,000 buildings were damaged in El Salvador.  About 585 of the deaths were caused by large landslides in Santa Tecla and Comasagua.  As is often the case after earthquakes in El Salvador, landslides wreaked significant damage.  Estimation of the number of slides is difficult because individual scarps conjoin.  The total has been reported as high as 16,000, though it is unclear how this figure was arrived at.  Damage and injuries occurred in every department of El Salvador, particularly the departments of La Libertad and Usulután.  Eight people were killed in Guatemala.  The tremor was felt from Mexico City to Colombia.  An aftershock measuring 5.7 magnitude was felt on January 15, an event not widely reported outside the country until after the February quake, which initially was assessed by the USGS at 5.7 magnitude as well.

El Salvador–Guatemala border: The El Salvador–Guatemala border is a 203 km international boundary in the northeast-southwest direction, northwest of El Salvador, and separating the country from the territory of Guatemala.  From north to south, it starts in the triple border of the two countries with Honduras, near the peak "Monte Cristo" in "Volcanoes National Park", extending to the southwest by the Pacific Ocean coast, following the final stage the Rio Paz .  It separates the department of Jutiapa in Guatemala from Ahuachapan (north) and Santa Ana departments in El Salvador.

Stirton's deer mouse: Stirton's deer mouse ("Peromyscus stirtoni") is a species of rodent in the family Cricetidae.  It is found in El Salvador, Guatemala, Honduras, and Nicaragua.  "P. stirtoni" is widely distributed and is presumed to have a large population and a tolerance of habitat destruction, though its biology is poorly understood.  The species is named after Ruben A. Stirton (1901-1966), an American zoologist associated with the University of California at Berkeley.
