🌋 Alert Level One for Taal Volcano

The Taal Volcano in the Philippines remains on alert level one following the release of volcanic smog on August 19. The Philippine Institute of Volcanology and Seismology reports that the volcano emitted 3,355 tons of sulfur dioxide and showed signs of upwelling hot volcanic fluids in its main crater. The agency classifies the volcano as experiencing a low level of unrest and advises against entry into the permanent danger zone, especially the main crater. Additionally, it warns of potential hazards such as steam-driven explosions, volcanic earthquakes, minor ash falls, and the lethal release of volcanic gases. In response to the volcanic smog, some municipalities in Batangas and Cavit have suspended classes or shifted to modular learning to mitigate exposure risks.

Keywords

💡Taal Volcano

Taal Volcano is an active volcano in the Philippines, known for its historical eruptions and its location within a lake. In the script, it is the main subject of concern due to its recent release of volcanic smog, indicating ongoing volcanic activity that requires monitoring and alert levels.

💡Alert Level One

Alert Level One signifies the lowest level of volcanic alert, indicating that the volcano is exhibiting signs of unrest but is not currently in an active eruption phase. The script mentions that Taal Volcano is still on this alert level, suggesting a state of vigilance without imminent danger.

💡Volcanic Smog

Volcanic smog, also known as 'vog,' is a type of air pollution resulting from volcanic emissions, composed of sulfur dioxide and other gases. The script reports the release of volcanic smog from Taal Volcano, which is a sign of volcanic activity and can pose health risks to the surrounding areas.

💡Philippine Institute of Volcanology and Seismology (PHIVOLCS)

PHIVOLCS is the government agency responsible for monitoring and studying the seismic and volcanic activities in the Philippines. The script cites PHIVOLCS as the source of information regarding the current status and recommendations for Taal Volcano.

💡Sulfur Dioxide (SO2)

Sulfur dioxide is a harmful gas that can cause respiratory problems and environmental damage. The script specifies that 3,355 tons of sulfur dioxide were released by Taal Volcano, highlighting the scale of the volcanic emissions and potential health and environmental impacts.

💡Upwelling

Upwelling refers to the rising of deep, hot water or magma towards the surface. In the context of the script, an upwelling of hot volcanic fluids in Taal Volcano's main crater is observed, indicating a potential for increased volcanic activity.

💡Volcanic Unrest

Volcanic unrest describes a period of increased seismic or volcanic activity without an actual eruption. The script mentions that Taal Volcano is in a low level of volcanic unrest, indicating that while there is activity, it is not escalating to an eruption.

💡Permanent Danger Zone

A Permanent Danger Zone is an area around a volcano that is considered hazardous due to the risk of volcanic activity. The script advises against entry into the Permanent Danger Zone of Taal Volcano, especially the main crater, to ensure public safety.

💡Steam-Driven Explosions

Steam-driven explosions occur when hot magma or volcanic gases interact with groundwater or surface water, causing an explosive release of steam and other gases. The script warns of the possibility of such explosions at Taal Volcano, which can be a sudden and dangerous event.

💡Volcanic Earthquakes

Volcanic earthquakes are seismic events associated with the movement of magma or the release of volcanic gases. The script mentions volcanic earthquakes as one of the potential hazards at Taal Volcano, indicating ongoing subsurface activity.

💡Lethal Accumulations or Expulsions of Volcanic Gas

This term refers to the dangerous buildup or release of volcanic gases that can be deadly due to their toxic nature. The script includes this as a potential hazard, emphasizing the risks associated with the release of gases like sulfur dioxide from Taal Volcano.

💡Class Suspensions and Modular Learning

Class suspensions and a shift to modular learning are measures taken by educational institutions to protect students from health hazards, such as volcanic smog. The script notes that some municipalities have implemented these measures in response to the conditions around Taal Volcano.
