Weak to moderate steaming, but sublimate deposits in possible decline

An aerial inspection took place after the 16 August, M 7.8 earthquake 200 km to the NW. Weak-to-moderate, white vapor emissions were observed from the main fumarole field in a valley on the N flank of the summit lava dome. Sublimate deposits in the valley appeared to be less extensive than when last inspected in 1989. The lake at Loloru's summit appeared normal. There was no discoloration of lake water and the level of water appeared to be unchanged.

Solfataras active on dome and flank

"Aerial inspection showed that dome and flank solfataras were active as normal. Water temperature most recently recorded in a pool by the stream draining the caldera lake was 80°C."

April 1988 (SEAN 13:04) Citation IconCite this Report

Higher fumarole temperature; sulfur ejected

"The main thermal area on the middle NE flank of the dome was visited on 25 April. A temperature of 108°C was measured at the main fumarole, which was surrounded by a mound of sulphur ~1 m high. Measurements since 1964 had obtained maximum temperatures of 93-97°C. Emissions from this fumarole formed a column up to 20 m high, and were accompanied by a low roaring sound. Both H2S and SO2 were detected, and occasional droplets of molten sulphur were ejected."
