Based on an automated impact model, this earthquake, which occurred in a region with low vulnerability to natural disasters, has potentially a low humanitarian impact.
Whether international humanitarian aid is needed must be decided by an expert.Event Date Univ.

The population in the area of this earthquake is 179 people/km?.
The earthquake occurred at 2h 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.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.
Algeria has a GDP per capita of 1569 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 Algeria a low vulnerability.ECHO Intervention Priority Ranking for Algeria Overall situation Human Development Human Poverty Exposure to Major Disasters Natural Disasters Conflicts Humanitarian effects of population movement Refugees and IDPs Health of children under five Undernourishment Mortality rates Other vulnerability factors Access to health care Prevalence of HIV, TBC and malaria Gender-specific Human Development Gini Index Source ECHO
Key: Bad - Medium - Good - No data Secondary effects
Probability of secondary effects:Landslides: The maximum slope in the area of the earthquake is 43.896% and the maximum altitude is 1700 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. Nuclear power plants: There are no nuclear facilities nearby the epicenter. Hydrodams: The following hydrodam installations are near the epicenter: Oued Rhiou (19km)
