The possible eruption of the Taal Volcano could lead to terrifying scenarios such as volcanic tsunamis, flying volcanic rocks, or base surges, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
On Thursday, January 16, 2020, GMA News Onlinereported that according to PHIVOLCS’ hazard map, several barangays in Batangas are at an increased risk of a tsunami or lakewater oscillation that could reach up to three meters high.
“Kung significant ‘yung volume na mahuhulog sa tubig, madi-displace din niya ‘yung tubig sa lake at ‘pag ganyan po, merong wave na maitutulak pupunta sa dalampasigan,” PHIVOLCS Director Renato Solidum explained in a 24 Oras report, GMA News Online wrote in a January 15 article.
In a January 15 report, GMA News Online also reported that other possible scenarios that might be caused by a volcanic eruption include base surges and flying volcanic rocks.
According to PHIVOLCS, base surges are a kind of pyroclastic density currents (PDCs), which are “hot gases and ash that rush down the volcanic slopes or rapidly outward from a source vent at high speeds.” PDCs are said to be “the most lethal of volcanic hazards” and can cause asphyxiation (suffocation), abrasion, incineration, and burial in the hot volcanic material.
A base surge can also instantly destroy properties and kill people along shoreline communities.
Director Solidum explained, “Kakalat po palayo mula sa crater ang eruption deposit at gagapang at posibleng tumawid sa tubig at umabot doon sa lupa.” The PHIVOLCS hazard maps also indicate that there are towns at risk of base surges.

Lastly, areas near Taal Volcano may also experience ballistic projectiles or materials, like gigantic rocks, spewed from the crater. Director Solidum said that when the volcano erupted in 1965, huge rocks hit boats and people in nearby areas.
Here is the list of areas in Batangas that are most susceptible to ballistic projectiles:
