In a special report for Taal issued on 15 November, PHIVOLCS noted that sulfur dioxide emissions were as high as 11,695 tonnes per day (t/d) and gas-and-steam plumes rose up to 1.2 km. A minor sulfur odor was reported in Banyaga, Agoncillo. High concentrations of gas had been continually emitted since March 2021; emissions averaged 6,267 t/d since September.
PHIVOLCS reported that the increased unrest at Taal continued during 8-14 November. Daily pronounced upwelling of gases and hot fluids in the lake generated steam-and-gas plumes that rose as high as 1 km above the crater and drifted SW. Sulfur dioxide emissions were 5282-11,499 tonnes per day (t/d); the highest being recorded on 9 November.

PHIVOLCS reported increased and continuous gas emissions at Taal in a special report issued on 12 October. Pronounced upwelling of gasses and hot fluids in the lake produced short plumes that drifted SW. Sulfur dioxide emissions were as high as 9,762 tonnes per day (t/d), the highest measurement recorded in 2023; emissions in September and October averaged 3,781 t/d.

PHIVOLCS reported that a series of seven significant but shallow tremors were recorded at Taal by all 15 seismic stations of the Taal Volcano Network during 0609-0900 on 13 July. Most of the events were located SE of Taal Volcano Island (TVI). Infrared camera images of Main Crater lake indicated increased thermal output.

PHIVOLCS reported continuing unrest at Taal during 26 June-4 July. Daily white steam-and-gas plumes, voluminous during the first half of the week, rose as high as 2.4 km above the lake and drifted NE, NW, S, and SW; voggy conditions were reported during 2-3 July. Upwelling gasses and hot fluids in the lake were periodically visible.

PHIVOLCS reported continuing low-level unrest at Taal during 13-20 June characterized by elevated seismicity, upwelling in the lake, and sulfur dioxide gas emissions. There were 20-38 daily volcanic earthquakes recorded during 13-17 June and a total of 11 recorded during 19-20 June. There were 2-46 daily periods of tremor, each lasting 2-67 minutes long.

PHIVOLCS reported continuing low-level unrest at Taal during 6-13 June characterized by elevated seismicity, upwelling in the lake, and sulfur dioxide gas emissions. Volcanic tremor located at shallow depths along the Daang Kastila fissure was continuous with almost 166 hours recorded during 2-9 June; periods of volcanic tremor also took place 4-7 times each day during 9-12 June, each lasting 2-97 minutes. There were 1-11 volcanic earthquakes recorded on most days.

In a 2 June advisory PHIVOLCS reported continuing low-level unrest at Taal. Starting at 0635 on 2 June relatively weak but continuous volcanic tremor located at shallow depths along the Daang Kastila fissure was recorded by all 15 seismic stations of the Taal Volcano Network. At the same time webcams recorded upwelling in Main Crater Lake on Taal Volcano Island (TVI) and more intense thermal anomalies in the N portion of the lake.
