Manado, North Sulawesi (ANTARA News) - The activity of North Sulawesi`s Mount Lokon is believed to have begun to decrease after its eruption on Sunday (Aug 28).

"Mount Lokon`s activity has begun to decrease but has not yet stopped," said Volcanological and Geological Disaster Mitigation Agency (PVMBG) spokesperson Gede Swantika here Monday.

The inactive phase could last up to 3-4 days and there would be another eruption in the near future, or after a few years, he said.

"Therefore we are evaluating recent developments in the mountain`s activity" Gede said.

He said some typical signs would be shown on the seismograph before the volcano erupted such as deep volcanic tremors.

"A lava plug will occur within this three-to-four day inactive phase, and energy will be released in an eruption. A number of deep volcanic tremors will also occur before it erupts," he said.

Gede also predicted the eruption that will occur will not exceed the earlier eruption on Sunday (Aug 28) in magnitude.

"So we don`t need to worry, and everybody can continue their daily activities, but everybody must obey the 2.5 kilometers radius danger zone from the crater, because of the threat of hot clouds is still possible," he said.

Mount Lokon erupted once again on Sunday (Aug 28) and spewed volcanic ash 2,500 meters into the sky.

Sabre grass fields on the mountain`s slopes ware burnt by 200-centigrade-hot rocks that were spewed out of its crater.

Mount Lokon last erupted on July 14 and 17, 2011 which forced thousands of residents of Kinilow Village I, Kinilow and Kakaskasen I, the District of North Tomohon, Tomohon to flee their homes.

On July 10, 2011, the alert level III status was raised to alert level IV, and lowered back to level II after the eruption on July 24, 2011.
