Spewing: expel large quantities of (something) rapidly and forcibly.
A volcano in the Philippines has begun spewing lava, as authorities warn that a "hazardous eruption" is possible "within hours or days".
In the early hours of Monday weak lava began flowing out of Taal volcano- located some 70km (45 miles) south of the capital Manila.
It comes after it emitted a huge plume of ash triggering the mass evacuation of 8,000 people from the area.
Taal is the Philippines' second most active volcano.
Situated on an island in the middle of a lake, it is one of the world's smallest volcanoes and has recorded at least 34 eruptions in the past 450 years.
"Taal volcano entered a period of intense unrest... that progressed into magmatic eruption at 02:49 to 04:28... this is characterised by weak lava fountaining accompanied by thunder and flashes of lightning," the Philippine Institute of Volcanology and Seismology (Phivolcs) said in a statement.
On Sunday, the volcano emitted a giant plume of ash, with rumbling sounds and tremors also reported.
