Green Earthquake Alert in Vanuatu

Summary

On 7/22/2010 5:04:01 AM UTC an earthquake of magnitude 6.2 and depth 35.2km has struck an moderately populated area in the Vanuatu Province (population: 0.1 million) in Vanuatu. 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 Narovorovo (5km). It is a mountainous region with a maximum altitude of 1429 m.

Earthquake Impact Details

shakemap

Potentially affected People

The population in the area of this earthquake if 2 people/kmē. (Data source).

The earthquake occurred at 16h 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%) and a low level of cultivated area (1.8%). In urban areas more damage can be expected than in cultivated or natural areas. (Data source)

Radius (km)urban areascultivated areasother

10 0% 14.89% 85.1%

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.

Vanuatu has a GDP per capita of 1347 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 Vanuatu 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

slopelevel Landslides: The maximum slope in the area of the earthquake is 34.46% and the maximum altitude is 1429 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:

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.
