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

The population in the area of this earthquake is 0 people/km?.
The earthquake occurred at 14h 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.
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.
Indonesia has a GDP per capita of 961 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 Indonesia a medium vulnerability.

Probability of secondary effects:
level Landslides: The maximum slope in the area of the earthquake is 0% and the maximum altitude is -4113 m. Since this is a low slope, the risk of earthquake induced landslides is low. 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.
level Nuclear power plants: There are no nuclear facilities nearby the epicenter.
level Hydrodams: There are no hydrodam facilities nearby the epicenter.
