A strong explosion was recorded at Sinabung volcano on January 9, 2016.

It was triggered by a volcanic earthquake that occurred about 8 minutes before.

The powerful explosion occurred at 21:48 pm and sent a column of ash and gas 3km in the air.

There was a volcanic earthquake for 490 seconds when the eruption occurred.

Ashfall was recorded in Berastagi City.

An exclusion zone has been implemented in a radius of 3 km around the volcanic peak.

Quake measured at a depth of 617 km, according to the US Geological Survey

A major undersea earthquake with a magnitude of 7.3 struck southeast of the Philippines on Tuesday, the US Geological Survey (USGS) said.

The quake was measured at a depth of 617 km (380 miles), the USGS said. It struck in the Celebes Sea and comes five days after a smaller, 4.7-magnitude tremor in the same area, according to the USGS.

Journalist Barnaby Lo said he felt "no significant tremor" on the island of Jolo, which lies north-east of the epicentre. The US Tsunami Warning Centre has issued no warning, advisory, watch or threat after the quake.

Philippine seismologists said the earthquake was far too deep to cause any damage and casualties or generate a tsunami.

A shallow magnitude 3 earthquake occurred almost directly under the summit of Teide volcano in 3 km depth today (at 12:18 UTC).

Whether the quake is volcanic in origin and might be a sign of a gradual reawakening of the volcano is impossible to say, but it is important to follow the volcano's seismic activity closely.
