On 3/12/2011 1:47:16 AM UTC (about 11:18h local time) an earthquake of magnitude 6.8 occurred in the unpopulated region of Tohoku in Japan. The earthquake happened 174km from Sendai. The nearest populated places are: [None]. The closest civilian airport is Sendai (167km).
It is likely that a tsunami was generated. The maximum tsunami wave height near the coast of Ide will be 0.04m. Please refer to the GDACS tsunami report for more details.
Potentially affected critical infrastructure:
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.

It is likely that a tsunami was generated. Based on precalculated scenarios, the maximum tsunami wave height near the coast of Ide will be 0.04m.
A detailed tsunami wave height calculation is ongoing and should be available 20 minutes after this report was created. Results can be slightly different than the precalculated scenario. The outcome can be checked here: GDACS tsunami report .

The population in the area of this earthquake is 0 people/km?.
The earthquake occurred at 11h 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.
Japan has a GDP per capita of 42317 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 Japan a low vulnerability.
Probability of secondary effects:
Landslides: The maximum slope in the area of the earthquake is 0%
and the maximum altitude is -126 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.
Nuclear
power plants:
The following nuclear installations are near the epicenter:
FUKUSHIMA-DAIICHI (147km), FUKUSHIMA-DAINI (149km), ONAGAWA (137km)
Hydrodams:
There are no hydrodam facilities nearby the epicenter.
Tsunami:
No tsunami risk.
