On 5/23/2010 10:46:51 PM UTC an earthquake of magnitude 6.1 and depth 94.8km has struck an moderately populated area in the Ayacucho Province (population: 0.5 million) in Peru. GDACS estimates the likelihood for need of international humanitarian intervention to be low (Green alert). This earthquake can have a low humanitarian impact since the affected region is moderately populated and has high resilience for natural disasters. The nearest populated places are Putaccasa (15km), Chullcopampa (17km), Llehuecclla (12km), Coripampa (6km), Huaccuto (17km), Soldaduyocc (6km), Ayacollpa (12km), Carapo (10km), Manchire (17km), Ccatapata (19km). It is a mountainous region with a maximum altitude of 4982 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 8 people/kmē. (Data source).
The earthquake occurred at 17h 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%) and a medium level of cultivated area (4.7%). In urban areas more damage can be expected than in cultivated or natural areas. (Data source)

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.
Peru has a GDP per capita of 2345 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 Peru 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.

Landslides: The maximum slope in the area of the earthquake is 80.037%
and the maximum altitude is 4982 m. Since this is a high
slope, the risk of earthquake induced landslides is high.
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...
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:
There are no hydrodam facilities nearby the epicenter.
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 (Cnl Alfredo Mendivil Duarte) is at 87km from the epicenter. Other airports are: Yauca (190km), San Juan De Marcona (181km), Nazca (124km), Andahuaylas (110km), Cnl Alfredo Mendivil Duarte (87km), San Francisco (165km)
Ports nearby are: San Juan (183km), San Nicolas (178km)
