Detection of Disaster Damage Using Changes of City Lights with DMSP/OLS Data in Asia Pacific Region
Fig. 4 The estimated impacted area of eruption of Usu volcano
4. Conclusions
The influenced areas of volcanic eruption were able to estimated, though the resolution of DMSP/OLS is coarse. It means that DMSP/OLS is suitable for detection not only of big earthquake area but also of volcanic eruption, as influencing to human activities.
ANDES project is trying to detect any disaster's damage using SIDaB. DMSP/OLS is useful for early detection of disaster, however digital value of visible-near infrared are saturated in heavy lightning area such as Tokyo or Osaka, even Sapporo city. It is hard to detect disaster damage in such area. Therefore, to detect disaster damage more effectively, we recommend using DMSP/OLS and other satellites.
