Regarding the 2011 off the Pacific coast of Tohoku Earthquake

International Workshop on Strategy of Volcanic Disaster Mitigation 2011---Big eruption & Crisis Management---

Date: 2-4 November, 2011
Venue:Yamanashi Institute of Environmental Sciences, Fujiyoshida(Nov. 2nd)

National Research Institute for Earth Science and Disaster Prevention, Tsukuba(Nov. 4th)


We have experienced big eruptions at many volcanoes and have suffered from tragic hazards. Especially for huge volcanic eruptions damaging wide areas around volcanoes, mainly due to volcanic ash falls, blasts, pyroclastic flows etc. The authorities face difficulties to judge how dangerous the activity would be and how to proceed disaster mitigation plan like evacuation of thousands of residents effectively under the collaboration of many local governments.

In this international workshop, we refer to some good experiences at Merapi, Montserrat and Vesuvio and discuss the effective procedures to deal with such huge volcanic eruptions and crisis. In session 1 at YIES (Nov. 2), we target the strategy of volcanic disaster mitigation of national and local governments. We also review the activity of local governments during the recent (2011) Kirishima volcano eruption, Japan, and obtain lessons. In session 2 at NIED (Nov. 4), we discuss on technological view of numerical simulations for evaluation of disasters due to volcanic ash fall, pyroclastic flows etc. For more quantitative estimation of volcanic hazards, numerical simulation is effective, but we have some limitations to apply them to actual strategy of political plan.
