On 12/13/2009 2:41:58 PM UTC an earthquake of magnitude 5.2 and depth 31.3km has struck an very highly populated area in the Chittagong Province (population: 14.7 million) in Bangladesh. GDACS estimates the likelihood for need of international humanitarian intervention to be medium (Orange alert). This earthquake can have a medium humanitarian impact since the affected region is very highly populated and has low resilience for natural disasters. The earthquake 32km from the city of Chittagong. The nearest populated places are Dhurung (15km), Napura (17km), Silkop (14km), Chhota Hatia (20km), Bailchari (10km), Jaldi (15km), Khankhanabad (8km), Banigram (12km), Charati (18km), Gahira (10km), Chandpur (17km), Burumchhara (16km). It is a hilly region with a maximum altitude of 959 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 838 people/kmē. (Data source).
The earthquake occurred at 20h local time. At this time a day, more people are at home and therefore more vulnerable to collapsing residential 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 high level of cultivated area (15.6%). In urban areas more damage can be expected than in cultivated or natural areas. (Data source)

|---|---|---|---|
| 200 | 0.01% | 15.61% | 84.36% |

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.
Bangladesh has a GDP per capita of 361 PPP$ (Parity Purchasing Power Dollar, about 1 Euro) and is therefore part of the low level income countries. Therefore, the earthquake happened in an area of low resilience.
Based on the combination of 9 indicators, ECHO attributes Bangladesh a high 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 31.744%
and the maximum altitude is 959 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...
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 (Patenga) is at 24km from the epicenter. Other airports are: Coxs Bazar (67km), Patenga (24km), Barisal (179km), Comilla (169km)
Ports nearby are: Maungdaw (143km), Elephant Point (98km), Cox's Bazaar (66km), Chittagong (31km)
