Mt. Bulusan erupts, spews 2-km high ash

Mt. Bulusan, located in Sorsogon, once again spewed a two-kilometer or 6,500 feet high column of ash during its eruption on Friday morning.

The volcano exploded around 11:35 a.m. It is said to have lasted for approximately five minutes. The eruption is phreatic in nature, as reported by Dr. Eduardo Laguerta, Philippine Institute of Volcanology and Seismology-Legazpi resident volcanologist.

Phreatic or better-known as steam-driven eruption is caused by ground water coming into contact with magma. The same kind of eruption has been documented since May last year.

Aside from the ash, other pyroclastic materials were also thrown out by the volcano during the eruption. Most of the emitted materials reached the northwest portion of the volcano, hitting the towns of Juban and Casiguran as well as villages in Irosin town.

Today’s eruption is the ninth time for the volcano. It has shown activity on February 22, as per Phivolcs records.

According to Laguerta, the volcano has a tendency to rest for several days, weeks or months before it explodes again. However, on the brighter side, the present activity of the volcano shows that it won’t be anything like the Mt. Mayon eruption.

The strongest eruption ever recorded for Mt. Bulusan was on 1922. However, despite this, Laguerta still warns the residents to be extra careful and to avoid entering the four-kilometer permanent danger zone. He also advices residents to use face masks to avoid inhaling ash.

Furthermore, it is important that residents, especially those who are living in valleys and close to rivers and waterways, be vigilant as these areas are vulnerable to lahar flows during heavy or prolonged rainfall.

Phivolcs Director Renato Solidum also issued a warning to pilots. He said that these individuals should not fly close to the crater as the ash is hazardous to aircraft.

Mt. Bulusan has a height of about 1,565 meters and is considered to be one of the 23 active volcanoes found in the country.
