Mendoza (, American Spanish: [mendosa]), officially the City of Mendoza (Spanish: Ciudad de Mendoza) is the capital of the province of Mendoza in Argentina. It is located in the northern-central part of the province, in a region of foothills and high plains, on the eastern side of the Andes. As of the 2010 census [INDEC], Mendoza had a population of 115,041 with a metropolitan population of 1,055,679, making Greater Mendoza the fourth largest census metropolitan area in the country.

Ruta Nacional 7, the major road running between Buenos Aires and Santiago, runs through Mendoza. The city is a frequent stopover for climbers on their way to Aconcagua (the highest mountain in the Western and Southern Hemispheres) and for adventure travelers interested in mountaineering, hiking, horse riding, rafting, and other sports. In the winter, skiers come to the city for easy access to the Andes.

Two of the main industries of the Mendoza area are olive oil production and Argentine wine. The region around Greater Mendoza is the largest wine-producing area in South America. As such, Mendoza is one of the eleven Great Wine Capitals, and the city is an emerging enotourism destination and base for exploring the region's hundreds of wineries located along the Argentina Wine Route.

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 size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The seismicity, or seismic activity, of an area is the frequency, type, and size of earthquakes experienced over a particular time period. 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 can also trigger landslides and, occasionally, volcanic activity.

In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter.
