An expected magnitude seven volcanic eruption would release as much energy as a 1-km asteroid impact.
, experts from the University of Cambridge’s Centre for the Study of Existential Risk and the University of Birmingham state that the world is unready for a gigantic volcanic eruption and the possible repercussions on global supply chains, climate, and food."Data gathered from ice cores on the frequency of eruptions over deep time suggests there is a one-in-six chance of a magnitude seven explosion in the next one hundred years.
An eruption in Tonga in January was the largest ever instrumentally recorded. According to the researchers, thewas the volcanic equivalent of an asteroid just missing the Earth and needs to be treated as a wake-up call," said Mani.The CSER experts cite recent research that detects the regularity of major eruptions by analyzing traces of sulfur spikes in ancient ice samples.
"An estimated 100,000 people died locally, and global temperatures dropped by a degree on average, causing mass crop failures that led to famine, violent uprisings, and epidemics in what was known as the year without summer," he said. However, the researchers argue that steps can be taken to protect against volcanic devastation, ranging from improved surveillance to increased public education and magma manipulation.
