Volcano monitoring with Landsat TM short-wave infrared bands: The 1990-1994 eruption of Unzen Volcano, Japan

The Unzen Volcano was active from 1990 to 1994 and in total 13 dacite lava lobes were formed successively at the eastern shoulder of Mount Fugen-dake. Surface temperature observation with nighttime Landsat-5 Thematic Mapper (TM) was conducted at the Unzen Volcano. The thermal anomaly areas up to 0.7...

More Information
Summary:The Unzen Volcano was active from 1990 to 1994 and in total 13 dacite lava lobes were formed successively at the eastern shoulder of Mount Fugen-dake. Surface temperature observation with nighttime Landsat-5 Thematic Mapper (TM) was conducted at the Unzen Volcano. The thermal anomaly areas up to 0.7 km 2 were detected in all the 23 cloud-free images of Landsat TM band 7. The patterns of temperature distribution correspond to the lava dome and the pyroclastic flow activity. The hot area change has been found to be closely related to the lava effusion rate.
