On 2/18/2009 9:53:45 PM UTC an earthquake of magnitude 6.9 and depth 25km has struck an unpopulated area in Off-shore area. GDACS estimates the likelihood for need of international humanitarian intervention to be low (Green alert). It is likely that a tsunami was generated. The maximum tsunami wave height near the coast of New Zealand will be 0m. Please refer to the GDACS tsunami report for more details. This earthquake can have a low humanitarian impact since the affected region is unpopulated and has low vulnerability to natural disasters. The nearest populated places are [None]. It is a flat region with a maximum altitude of -621 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 0 people/kmē. (Data source).
The earthquake occurred at 10h 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 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.
The earthquake epicenter is not located on the territory of a country. Therefore, no resilience information is available.
Based on the combination of 9 indicators, ECHO attributes Off-shore area a low 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.
Current weather conditions and forecasts at earthquake location (lat: -27.4149 - long: -176.4187) (Data source).
Landslides: The maximum slope in the area of the earthquake is 0%
and the maximum altitude is -621 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. More...
Tsunami:
the JRC tsunami wave propagation models indicated a unknown likelihood for a destructive tsunami.
However, this probability must be confirmed by oceanographic measurements or
observations.
See full report.
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.
There is no airport within 100km.
Ports nearby are: [None]
