Taal volcano is one of the most active volcanoes in the Philippines and has produced some of its most powerful historical eruptions. Six of 24 known eruptions at Taal since 1572 have caused fatalities, many from tsunamis in the crater lake.

An eruption of Taal in 1911 killed 1334 people and produced ash which reached Manila. An increase in seismicity was recorded at the volcano in November 2006, and hot bubbling water was recorded in the crater in April 2007.

2012 Unrest
There was a large increase in seismic activity at Taal volcano on 22-23 November 2012. In a 24 hour period 60 earthquakes were measured at the volcano. Two of the earthquakes were felt by residents of Calauit and Pira-piraso. The second felt earthquake at 7:23 pm on 22 November was felt with an intensity of III, and was accompanied by a rumbling sound. The earthquakes were located mostly under the north-eastern side of the volcano island.

2011 Unrest
Taal volcano in the Philippines has been placed on level 2 alert in April 2011 due to an intrusion of Magma towards the surface. The temperature of the main crater lake has increased to 31.5 deg C. There has been a small inflation of the volcano. High levels of carbon dioxide have been released in the main crater and seismic activity is elevated. PHIVOLCS has advised the Main Crater, Daang Kastila Trail and Mt. Tabaro are closed to visitors due to the risk of explosion, and emission of toxic gas. 

2010 Unrest
Since 26th April 2010 volcanic earthquakes have increased. Between 11-24 May the temperature in the crater lake increased by 2-3 dec C. The composition of Main Crater Lake water has shown above normal values of Mg/Cl, SO4/Cl and Total Dissolved Solids. There has been ground steaming accompanied by hissing sounds on the northern and northeast sides of the main crater. PHIVOLCS has raised the status of the volcano to Alert Level 2, which indicates the volcano is undergoing magmatic intrusion which may lead to an eruption. The main crater has been placed off limits due to the risk of an eruption.

2008 Earthquakes
Seismic unrest was reported at Taal volcano in Philippines. On 28th August, 10 earthquakes were recorded at the volcano. Earthquakes were felt by residents of barangay Pira-piraso village, and accompanied by rumbling sounds. The earthquakes were located northeast of the volcano island near Daang Kastila. An exclusion zone has been placed around the crater. The northern portion of the Main Crater rim, near Daang Kastila Trail, may be hazardous.

2006 Earthquakes
An increase in seismicity was recorded at Taal Volcano in Philippines in November 2006. The earthquakes were accompanied by rumbling sounds. Geysers of muddy water 3-5 m high occurred in the NNE portion of the main crater. The main crater was placed off limits because of the possibility of explosions or gas emissions.

2004 Earthquakes
An increase in seismic activity was recorded at Taal volcano in the Philippines in November 2004, with 31 high frequency earthquakes in seven days. Epicenter locations were in the vicinity of Main Crater and to the NNW near Binintiang Malaki and to the SSE near Calauit. There was an increase in water temperature and acidity in the crater lake. Taal volcano has been placed on Alert level 1 (out of 5) which means that there is magmatic, tectonic or hydrothermal disturbance; but no eruption imminent.

1965 Eruption
A phreatomagmatic eruption of Taal volcano between 28-30 September 1965. The eruption covered an area of approximately 60 square kilometres with ash more than 25 cm thick. The 1965 eruption was the first since 1749 to be located on the flanks of the island.

1911 Eruption
The eruption of Taal volcano in 1911 destroyed most life on the island and cause damage to the surrounding area. 1335 people were killed in the eruption.
