Mount Pinatubo[ 4 ] is an active stratovolcano in the Zambales Mountains in Luzon in the Philippines. Located on the tripoint of Zambales, Tarlac and Pampanga provinces, [ 5 ][ 6 ] most people were unaware of its eruptive history before the pre-eruption volcanic activity in early 1991.
A map of Mount Pinatubo showing nearby peaks and the evacuation zones. In early June, tiltmeter measurements had shown that the volcano was gradually inflating, evidently due to fast-growing amounts of magma filling the reservoir beneath the summit. At the same time, seismic activity, previously concentrated at a depth of a few kilometers below ...
Lake Pinatubo (Filipino: Lawa ng Pinatubo) is the summit crater lake of Mount Pinatubo formed after its climactic eruption on June 15, 1991. The lake is located in Botolan, Zambales, near the boundaries of Pampanga and Tarlac provinces in the Philippines. It is about 90 km (56 mi) northwest of the capital city of Manila.
Although the mountains are volcanic in origin, [2] Mount Pinatubo is the only active volcano in the mountain range. Its eruption on June 15, 1991 was the second most powerful volcanic eruption of the 20th century after the 1912 eruption of Novarupta in Alaska.
The Toba eruption (sometimes called the Toba supereruption or the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago during the Late Pleistocene [2] at the site of present-day Lake Toba in Sumatra, Indonesia. It was the last in a series of at least four caldera -forming eruptions at this location, with the ...
The 1991 Ultra-Plinian eruption of Mount Pinatubo was the second largest terrestrial eruption of the 20th century (surpassed only by the 1912 eruption of Novarupta), and the largest eruption in living memory. The eruption produced high-speed pyroclastic flows, giant lahars, and a cloud of volcanic ash hundreds of miles across. [2]
Fumarolic with solfataras and thermal springs. Babuyan Claro. 843. 2,766. 19°31′23″N121°56′24″E / 19.523°N 121.940°E / 19.523; 121.940 (Babuyan Claro) Cagayan. 3. Eruptions were recorded in 1831, 1860 and 1913. Askedna Hot Springs is in the southern base of the volcano.
Inactive does not necessarily indicate the volcano will not erupt again. Mount Pinatubo had no recorded historical eruption before its cataclysmic 1991 eruption. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) currently lists 355 volcanoes in the Philippines as inactive. [2]
