Chaparrastique
San Miguel (also known as Volcán Chaparrastique) is a stratovolcano in central-eastern El Salvador, approximately southwest of the city of San Miguel. On January 16, 2002, a minor eruption of steam, gas, and ash occurred from the summit crater, lasting 3 hours but causing no real damage to life or property. Carbon dioxide emissions had been monitored since November 2001, and their steady increase continued to build up until the eruption. Eleven years later, on December 29, 2013, San Miguel erupted at 10:30 local time spewing ash and smoke into the sky, and prompted the evacuation of thousands of people living in a 3 km (1.9 mi) radius around the volcano.San Miguel volcano (El Salvador): new eruption ''Volcano Discovery''.

San Miguel, El Salvador
San Miguel () is a city in eastern El Salvador. It is the country's third most populous city. It is located 138 km east of the capital, San Salvador. It is also the capital of the department of San Miguel and a municipality. The population of the city in 2017 was 518,410. History Luis de Moscoso Alvarado established the village of San Miguel de la Frontera (Saint Michael of the Frontier) on May 8, 1530, as a bastion for the conquest of the Lenca kingdom of Chaparrastique (Place of Beautiful Orchids). By 1586 the village had obtained the title of city. In 1655, a volcanic eruption almost destroyed the entire city. According to legend, the devastation was so severe that only an image of Mary in the parish church was spared. Economy The city has been an important center of the agriculture, textile and chemical industries of El Salvador. Since the early 21st century, the services sector, especially health care and commerce, have increased considerably, resulting in significa ...

San Miguel Department (El Salvador)
San Miguel () is a department in the eastern part of El Salvador. The capital is San Miguel. The department is 2,077 km2 in area and has a population of over 678,000. Before the Spanish conquest of El Salvador, the territory that now consists of the departments of San Miguel, La Unión and Morazán was the Lenca kingdom of Chaparrastique (Place of Beautiful Orchids). San Miguel was first known as San Miguel de la Frontera. The city was founded by Luis de Moscoso on May 8, 1530, where it is now Santa Elena. On July 11, 1812, the city was given the title of "Noble y Leal Ciudad" (noble and loyal city). It was made a department on June 12, 1824. It is the location of Ciudad Barrios, the birthplace of Archbishop Óscar Romero.

El Salvador
El Salvador (; , meaning " The Saviour"), officially the Republic of El Salvador ( es, República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2022 is estimated to be 6.5 million. Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemal ...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Summit Crater
A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoes, and these are commonly referred to ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely follow ...

Seismic Activity
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 ...

Chinameca (volcano)
Chinameca (also known as El Pacayal) is a stratovolcano in central-eastern El Salvador. It lies north of San Miguel volcano and rises over the town of Chinameca.
