摘要：Many active volcanoes are distributing in east Asia, however, most of them are not well monitored. Monitoring volcanoes is a key issue for disaster mitigation, as well as scientific studies. It is not realistic to install ground-based instruments to all of the active volcanoes, thus virtually satellite remote sensing is the only way to monitor them scattering in such wide areas. We developed a monitoring system based on Moderate Resolution Imaging Spectroradiometer (MODIS) and Multi-functional Transport Satellite (MTSAT) data, and are currently monitoring 147 active volcanoes in this area. The observation results are uploaded on the website in real or near-real time, after acquisition of observation data. Based on these data, we analyzed details of eruption processes occurred at Asama and Sarychev Peak in 2009, in conjunction with high resolutions images or ground-based observations. We plan to improve the current monitoring system utilizing the advanced observation capabilities of GCOM-C1 SGLI launching in 2014. The SGLI 1.6 μm and 11 μm channels have 250 m resolution, which is four times higher than that of 3.7 μm and 11 μm channels of MODIS. These high resolution channels enable to operate more sensitive thermal monitoring of volcanic activities
