Dozens of mild quakes have occurred over the past several days at Mount Dempo in Pagaralam, South Sumatra.
However, its status as an active volcano is still listed as "normal", a local seismic researcher said.
"Dozens of mild volcanic and tectonic quakes will not significantly affect the mountain," Mount Dempo observation post chief Slamet said in Pagaralam Friday, as quoted by Tempointeraktif.com.
Slamet did not elaborate on the exact size of the earthquakes.
Following the eruption of Mount Merapi in Central Java, Mount Dempo showed six mild volcanic and tectonic quakes on Tuesday, as well as six volcanic tremors on Wednesday, Slamet said, adding that the government once raised Mount Dempo's status to the second highest level in 2008.
"After the Merapi eruption, Mount Dempo is a high priority at the Bandung Center of Geology, Vulcanology and Disaster Mitigation," he said.
Despite the relatively mild nature of the tremors, Slamet said he had to remain cautious of possible future activity at Mount Dempo. -The Jakarta Post/ANN
