Volcanic plume monitoring system for the Usu 2000 eruption.

Abstract

A volcanic plume monitoring system for the Usu 2000 eruption was made in order to get plume images for a long duration. The monitoring system consists of two systems: (1) a real-time monitoring image server system with a remote-control camera and (2) an automatic still-image capturing system taking at 5 minutes intervals. These systems were installed on June 4, 2000 at an observation point at the northwestern part of the Toya Lake, north of the Usu Volcano. All captured volcanic plume still images taken for more than half a year can be seen at the GSJ web site. Variations of volcanic plume conditions were observed from these images.
