Many may still remember the powerful eruption of Mount Pinatubo in 1991. It was one of the largest eruptions in recent history, and sent volcanic ash even as far as Singapore, over 2,400 kilometres (km) away.
Mayon, on Luzon Island in the Philippines, entered a new eruptive phase on 13 January 2018, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Philippines’ Geological Agency. This phase included steam-driven eruptions and flows from a new lava dome growing at the summit of the volcano.
Humans are fabulous agents of geologic change. What do I mean by this? We reduce the height of mountains via mountaintop mining to obtain energy resources. We blast through a mountain to make a road cut, or tunnel. We make new lakes by building dams for hydroelectric power. Indeed, we humans are capable of changing the landscape or environment (or climate for that matter) at rates much faster than normal geologic processes.
