JAKARTA, Aug. 9 (Xinhua) — Indonesian authorities upgraded on Friday the emergency status of Mount Slamet in Central Java province from normal status of Level I to higher alert grade of Level II as tectonic and deformation activities at the volcano continue to escalate.

“Some 51,511 land tremors have been recorded since June until recently on Thursday that include 5 local tectonic tremors and 17 distant tectonic tremors. Land tremors with maximum amplitude between 0.5 to 2 millimeters have started to occur since in late July. Energy from the tectonic activities have been detected of gradually rising,” PVMBG said in a statement.
Despite the apparent tectonic activities escalation, visual signs of eruption has not been seen at present.
“Eruption may occur anytime in the future,” the PVMBG warned.
Should the eruption happens, 2 kilometers of areas around the volcano crater may get affected by the smoldering volcanic materials and volcanic ashes.
As the alert status has been upgraded to level II, residents, tourists and trekkers are highly advised not to make any activities within a radius of 2 kilometers at from the volcano summit.
Provincial government as well as related disaster mitigation agencies are advised to intensify coordination with the volcano observation outposts to monitor development of the situation.
