Photo: @randyolson | Mount Pinatubo is an active stratovolcano that was inconspicuous and obscured from view. It was covered with dense forest which supported a population of several thousand indigenous people.
The volcano's Plinian / Ultra-Plinian eruption on 15 June 1991 produced the second largest terrestrial eruption of the 20th century
The effects of the eruption were felt worldwide. It ejected roughly 10,000,000,000 tonnes of magma, Global temperatures dropped by about 0.5 °C (0.9 °F) in the years 1991-93, and ozone depletion temporarily increased. @natgeocreative @thephotosocoety @theimagereview #aerial #mountain #travel #landscape #asia #philippines
