Bulusan Volcano, Philippines: Recent alert for volcanic eruption

Bulusan Volcano is renowned for its sporadic steam-driven or phreatic eruptions. Since 1885, it has erupted a total of 15 times, earning it the distinction of being the fourth most active volcano in the Philippines, following Mayon, Taal, and Kanlaon.

    Bulusan Volcano is a popular tourist destination, particularly for hiking and camping. The volcano is also home to a variety of unique flora and fauna, including the Bulusan hornbill and the Bulusan dwarf deer.

    👉  Location of Bulusan Volcano

    Bulusan Volcano is situated on the island of Luzon within the Philippines. It is a stratovolcano (a conical volcano built up by many layers (strata) of hardened lava and tephra), found in the province of Sorsogon, part of the Bicol Region. It is positioned approximately 70 kilometers (43 miles) to the southeast of Mayon Volcano and roughly 390 kilometers (240 miles) to the southeast of Manila. Among the active volcanoes in the Philippines, Bulusan is noteworthy.

    👉  The most recent eruption of Bulusan Volcano

    The most recent eruption of Bulusan was on June 12, 2022. The eruption was characterized by a series of phreatic explosions that generated ash columns up to 2 kilometers high. The eruption also caused minor lahars and pyroclastic flows.

    👉  Recent alert for volcanic eruption of Bulusan Volcano

    The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised Alert Level 1 over Bulusan Volcano on October 25, 2023 due to increased seismicity. This means that the volcano is currently in an abnormal condition and there is a slight increase in the possibility of phreatic eruptions.

    PHIVOLCS has advised the public to avoid entering the 4-kilometer radius Permanent Danger Zone (PDZ) around the volcano. Local government units and the public are also reminded that entry into the 2-kilometer Extended Danger Zone (EDZ) on the southeast sector must be strictly prohibited.

    PHIVOLCS is closely monitoring Bulusan Volcano and will provide regular updates on its status.

    If you have any questions or concerns about Bulusan Volcano, please contact PHIVOLCS at +63 (2) 8929 7091 or 177.

    👉  What is Stratovolcano? Notable Examples of stratovolcanoes

    Stratovolcano is a type of volcano that is built up by many layers (strata) of hardened lava and tephra (fragments of volcanic rock and ash). Stratovolcanoes are also known as composite volcanoes because of their composite stratified structure.

    Stratovolcanoes are typically steep-sided and conical in shape, with a summit crater. They are often found above subduction zones, where one tectonic plate is sliding beneath another. The magma that erupts from stratovolcanoes is typically felsic, which means that it is high in silica. Felsic magma is thick and sticky, and it often forms explosive eruptions when it reaches the surface.

    Stratovolcanoes are some of the most active volcanoes in the world, and they have been responsible for some of the most devastating volcanic eruptions in history. For example, the eruption of Mount Vesuvius in 79 AD buried the Roman city of Pompeii, and the eruption of Krakatoa in 1883 caused a tsunami that killed over 36,000 people.

    👉  Notable Examples of stratovolcanoes:

        Mount Fuji, Japan

        Mount Rainier, USA

        Mount St. Helens, USA

        Mount Vesuvius, Italy

        Mount Etna, Italy

        Mount Kilimanjaro, Tanzania

        Mount Cotopaxi, Ecuador

        Mount Popocatepetl, Mexico

        Mayon Volcano, Philippines

        Mount Apo, Philippines

        Mount Talamo, Philippines

        Bulusan Volcano, Philippines

    Stratovolcanoes are an important part of the Earth's geological system. They play a role in the distribution of heat and energy on the planet, and they also contribute to the formation of new rocks and minerals.
