On 3/11/2010 2:55:27 PM UTC an earthquake of magnitude 6.7 and depth 18km has struck an highly populated area in the Libertador General Bernardo O'Higgins Province (population: 0.7 million) in Chile. GDACS estimates the likelihood for need of international humanitarian intervention to be medium (Orange alert). It is likely that a tsunami was generated. The maximum tsunami wave height near the coast of La Villa will be 0.27m. Please refer to the GDACS tsunami report for more details. This earthquake can have a medium humanitarian impact since the affected region is highly populated and has high resilience for natural disasters. The earthquake 143km from the city of Valpara”so. The nearest populated places are Larra”n Alcalde (20km), T£nel del ?rbol (17km), Alcones (19km), Cardonal (16km), Marchige (15km), Los Ranchones (14km), Chequ_n (18km), Viluco (17km), La Aguada (14km), La Estrella (19km), Villa de Cartagena (11km), Cartagena (15km), El Culenar (15km), El Tonel (18km).It is a mountainous region with a maximum altitude of 2217 m.
Caution: this information is based on risk models. Whether international humanitarian aid is needed must be decided by an
expert.

The population in the area of this earthquake if 17 people/km². (Data source).
The earthquake occurred at 10h local time. At this time a day, more people are at work and therefore more vulnerable to collapsing office buildings. During traffic hours, people can be affected by collapsing bridges and other road infrastructure.

The affected region has low level of urban area (0.4%) and a high level of cultivated area (29.1%). In urban areas more damage can be expected than in cultivated or natural areas. (Data source)
| Radius (km) | urban areas | cultivated areas | other |
|---|---|---|---|
| 200 | 0.41% | 29.15% | 70.42% |

Resilience is the capacity of the population to cope with a hazard. Since much of investments in earthquake preparedness and available funds for quick response is related to household income, the GDP per capita can be used as a rough indicator of resilience.
Chile has a GDP per capita of 5121 PPP$ (Parity Purchasing Power Dollar, about 1 Euro) and is therefore part of the high level income countries. Therefore, the earthquake happened in an area of high resilience.
Based on the combination of 9 indicators, ECHO attributes Chile a low vulnerability.

Both conditions for survival and conditions for delivering aid strongly depend on the current weather and temperature. The following graphs show the current and forecast weather.

More detailed observations at closest weather station (Rapelhuapi): WeatherByWeb - NOAA
Landslides: The maximum slope in the area of the earthquake is 49.064%
and the maximum altitude is 2217 m. Since this is a medium
slope, the risk of earthquake induced landslides is medium.
Note, however, that the slope data is not reliable on a local scale, while
landslides depend very much on local topography, soil and meteorological
conditions. More...
Tsunami:
the JRC tsunami wave propagation models indicated a unknown likelihood for a destructive tsunami.
However, this probability must be confirmed by oceanographic measurements or
observations.
See full report.
The following critical infrastructure is nearby and could be affected by the earthquake:
Nuclear power plants:
There are no nuclear facilities nearby the epicenter.
Hydrodams:
The following hydrodam installations are near the epicenter: [None]
The distance to nuclear installations is evaluated based on a 1999 UN dataset containing the location of nuclear plants in the world. If plants are near and the earthquake magnitude is above 6.5, the alert is set to orange. Note that the location of plants is approximate with errors of up to 100km.
The nearest civilian airport (Rapelhuapi) is at 36km from the epicenter. Other airports are: Linares (178km), Panguilemo (124km), Quivolgo (124km), De La Independencia (98km), Rapelhuapi (36km), El Bosque (133km), Los Cerrillos (137km), Eulogio Sanchez (151km), Arturo Merino Benitez International (138km), La Victoria De Chacabuco (172km), El Belloto (143km), Vina Del Mar (152km), San Rafael (197km), Quintero (168km)
Ports nearby are: Constitucion (126km), San Antonio (80km), Valparaiso (140km), Quintero (169km)
