Based on information from JMA, the Tokyo VAAC reported that during 16-17 and 19-22 November explosions from Sakura-jima produced plumes that rose to altitudes of 1.8-3 km (6,000-10,000 ft) a.s.l. and drifted S, SE, E, and N. Satellite imagery on 16 and 21 November showed ash emissions that later dissipated. On 19 November a pilot reported an ash plume at an altitude of 3 km (10,000 ft) a.s.l.

Summary

On 11/24/2011 10:25:34 AM UTC an earthquake of magnitude 6.2 and depth 42.3km has struck an moderately populated area in the Hokkaido Province (population: 5.8 million) in Japan. GDACS estimates the likelihood for need of international humanitarian intervention to be low (Green alert).

This earthquake can have a low humanitarian impact since the affected region is moderately populated and has high resilience for natural disasters.

The earthquake 170km from the city of Sapporo. The nearest populated places are [None]. It is a mountainous region with a maximum altitude of 1866 m.

Explanation of alert calculation: Show


The impact model combines magnitude (M), population within 100km (P) and vulnerability/resilience ECHO average score (V) using the formula:
alertscore = max(M-4.5,0) * log10(max(P / 80000,0))^ 0.5 * max(V,0.5) ^ 1.5 / 3
The weighted product of magnitude (6.2), population (118353) and vulnerability (0.5) results in an alertscore of 0.233703998532809
Then alert is Red if alertscore>2, Orange if alertscore>1 and Green if alertscore

Potentially affected People

The population in the area of this earthquake if 4 people/km?. (Data source).

The earthquake occurred at 19h 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.

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.

Exposure

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.

Probability of Secondary effects

damlevel Landslides: The maximum slope in the area of the earthquake is 36.124% and the maximum altitude is 1866 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...

Critical infrastructure

The following critical infrastructure is nearby and could be affected by the earthquake:

  • envelope Nuclear power plants: There are no nuclear facilities nearby the epicenter.
  • ocha 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.

Earthquake Impact Details

slopelevel

Potentially affected People

The population in the area of this earthquake if 12 people/km?. (Data source).

The earthquake occurred at 4h 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.

Damage

The affected region has low level of urban area (0.2%) and a high level of cultivated area (5.7%). In urban areas more damage can be expected than in cultivated or natural areas. (Data source)

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.

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.

Exposure

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.

Probability of Secondary effects

ocha Landslides: The maximum slope in the area of the earthquake is 20.708% and the maximum altitude is 1119 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...

Critical infrastructure

The following critical infrastructure is nearby and could be affected by the earthquake:

  • ocha Nuclear power plants: There are no nuclear facilities nearby the epicenter.
  • jrc Hydrodams: The following hydrodam installations are near the epicenter: (35km), FUKUSHIMA-DAINI (35km), ONAGAWA (116km), TOKAI (123km)

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.

Getting there and away

The nearest civilian airport (Sendai) is at 98km from the epicenter. The Military airfield of Fukushima is located at 89km from the epicenter. Other airports are: Ryugasaki South (196km), Ryugasaki (192km), (183km), Hyakuri (159km), Suzumenomiya (170km), Utsunomiya (167km), Otawara (135km), Fukushima (89km), Sendai (98km), Kasuminome (107km), Matsushima (118km), Junmachi (149km), Ojojibara (138km)

Ports nearby are: Choshi (188km), Kashima (174km), Hitachi (119km), Onahama (65km), Soma (66km), Shiogama (112km), Ishinomaki (118km), Onagawa (120km), Kesennuma Ko (169km), Ofunato (191km)
