So what can happen when an earthquake hits?
... What makes a building fail in earthquakes? An Earthquake moves the ground. It can be one sudden movement, or more likely a series of shock waves at short intervals. It can move the land up and down, and it can move it from side to side. All buildings are strong enough to support their own weight an ...

Earthquakes
... The sudden, violent movement at the focus send out seismic waves in all directions. It is these waves that cause the ground to move – and so cause damage.

2010 Pichilemu earthquake
The 2010 Pichilemu earthquake (Spanish: Terremoto de Pichilemu de 2010), also known as the Libertador O'Higgins earthquake, was a 6.9 MW intraplate earthquake that struck Chile's O'Higgins Region on 11 March 2010. The earthquake was centred 15 kilometres (9.3 mi) northwest of the city of Pichilemu, according to the University of Chile Seismological Service.The earthquake was caused by increased regional stress arising from an earthquake on 27 February, centered offshore Maule Region, which was felt throughout central Chile. The 11 March earthquake was at first thought to be an aftershock from the 27 February event, but University of Chile Seismologist Jaime Campos identified it as an ""independent earthquake"". The Hawaii-based Pacific Tsunami Warning Center pointed out the possibility of local tsunamis within 100 kilometres (62 mi) of the epicentre, although small, but violent waves were seen in the Pichilemu and Bucalemu area. One person was reported dead. At least eleven aftershocks immediately followed, causing panic throughout coastal towns between the Coquimbo and Los Lagos regions.The earthquake was specially destructive in the epicentre town, Pichilemu, capital of Cardenal Caro Province. The city hosts five National Monuments of Chile, of which two, the Agustín Ross Park and the Agustín Ross Cultural Centre, were seriously damaged by the earthquake. It also damaged the villages of La Aguada and Cardonal de Panilonco. Rancagua, the capital of O'Higgins Region, was also damaged, leading President Sebastián Piñera to declare a catastrophe state in O'Higgins Region.
