Pinatubo volcano (Luzon, Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 21 September-27 September 2022 (Continuing Activity)

10:00 AM | BY: VN

On 25 September PHIVOLCS warned of potential lahars around Pinatubo due to intense rains from a typhoon expected during 25-26 September. Significant deposits from 1991 pyroclastic density currents on the W flank may be remobilized, generating lahars down major drainages in that watershed. PHIVOLCS noted that the communities of San Marcelino, San Narciso, San Felipe, and Botolan, Zambales Province, and communities in Tarlac and Pampanga Provinces may be affected by lahars and flooding.

Pinatubo (Philippines) - Report for 24 November-30 November 2021 - NEW

PHIVOLCS reported that a weak phreatic explosion at Pinatubo was recorded during 1209-1213 on 30 November. The event was likely drive by shallow hydrothermal processes based on very low seismicity recorded during the previous few days, low diffuse carbon dioxide flux from the lake, and a notable infrasound signal. A plume mostly comprised of steam was seen rising above weather clouds within a few minutes of the end of the event. ... Read all

Pinatubo Volcano increase in seismic activity, no imminent eruption foreseen

Since its alert level increase from 0 to 1 last 4 March 2021, Pinatubo Volcano had only experienced about 1 to 9 daily volcanic quakes. According to the latest volcano bulletin issued by PHIVOLCS today, 8 March 2021, there has been an increase in number of volcanic quakes recorded. In the last 24 hours, a total of 35 quakes were recorded. However, these quakes may be related to “tectonic processes beneath its edifice, and that no imminent eruption is foreseen”. Read all
