Green Earthquake Alert in Ecuador

Summary

On 8/12/2010 11:54:16 AM UTC an earthquake of magnitude 7.1 and depth 211km has struck an unpopulated area in the Pastaza Province (population: 0 million) in Ecuador. 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 isunpopulated and has high resilience for natural disasters. The earthquake 176km from the city of Quito. The nearest populated places are Capricho (17km), Tihuano (11km). It is a mountainous region with a maximum altitude of 3526 m. Humanitarian Impact Population resilience Tsunami probability Landslide probability Nuclear radiation probability Caution: this information is based on risk models. Whether international humanitarian aid is needed must be decided by an expert.

Earthquake Impact Details

Potentially affected People

The population in the area of this earthquake if 0 people/km². (Data source).

The earthquake occurred at 6h 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.

Damage

The affected region has low level of urban area (0.1%) and a high level of cultivated area (13.7%). In urban areas more damage can be expected than in cultivated or natural areas. (Data source)

Radius (km)	urban areas	cultivated areas	other
200	0.13%	13.77%	86.08%
100	0%	17.62%	82.37%
50	0%	12.97%	87.02%
10	0%	12.08%	87.91%

Resilience and Vulnerability

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.

Ecuador has a GDP per capita of 1418 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 ofhigh resilience.

Based on the combination of 9 indicators, ECHO attributes Ecuador a low vulnerability.

Exposure

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.

Probability of Secondary effects

Landslides: The maximum slope in the area of the earthquake is 46.809% and the maximum altitude is 3526 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...

Critical infrastructure

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.
