Fish kill in Lake Ranau LAMPUNG - Since early last month, fish kill is taking place in the Ranau Lake, located inside an old volcano in Lampung province in southern Sumatra. The area under the current lake is still geologically and volcanologically active, which causes the lake to change colors sometimes because of chemical processes.

According to residents, the fish kill started at April 4, 2011. The fish kill however, was limited to a small part of the lake in the area where a geyser exhausted hot water from the earth's crust to the surface. At the location where the dead fish were found, the color of the water had changed to whitish and the odor of sulfur is present as well.

Earlier cases of fish kill in the lake occurred in 1962, 1993, 1995 and 1998. In all cases not the entire lake, with a surface of 127 sq.km., was hit. The lake itself is located inside the old caldera of the Semingung volcano, which is in it's turn located near an important fault-line. The volcano itself is not active, and has not been active in recent history.

At the location where fish kill takes place, research has been done. This research shows that the water around these locations have a pH-value of between 7.74 and 8.10, while temperatures have been measured between 26.1C and 62C. Volcanism below the lake also produced CH4, CO2, CO and H2S.

Directly below the lake, up to a depth of 10 kilometers, small volcanic tremors are measured as well. A week before the fish kill started, there was a powerful earthquake at some 160 kilometers southwest of the lake. It is not known whether the two incidents are related, but further investigations are ongoing.
