The 5.1 Richter scale tectonic earthquake in Bengkulu on March 29, 2011, triggered an increase in pressure on the fault around Lake Ranau.

In conclusion, the cause of fish deaths in Lake Ranau was the release of H2S sulfur gas into the water.

As a result, there is a change in the lake's water balance system.

Previously, the phenomenon of sudden fish death also occurred in Lake Maninjau, Agam Regency, West Sumatra, in February 2022.
