Superheated volcanic gas was causing the red glow at the crater of Kanlaon Volcano, Mari Andylene Quintia, PHIVOLCS resident volcanologist, said Sunday night, May 10.
A superheated plume is magmatic gas being emitted by the volcano, she said.
Close-up photos showing superheated volcanic gas from the summit crater of Kanlaon Volcano were captured via DSLR Camera from the Kanlaon Volcano Observatory – Canlaon City station at 11:40 p.m. Saturday, and 7:03 p.m. Sunday, May.
While superheated volcanic gas plumes have been recorded since 2024, only on Sunday did it become visible to the naked eye, a phenomenon called crater glow or “banaag,” the Negros Occidental Operations Center said.
The public is advised to stay alert and await further advisories from the Philippine Institute of Volcanology and Seismology, it added.*
