It sounds promising, but what happens if the satellites fail to predict a serious eruption? The case of the convicted but later exonerated Italian earthquake experts springs to mind.
A UK-led team of scientists is rolling out a project to monitor every land volcano on Earth from space, reports BBC News.
Two satellites will routinely map the planet’s surface, looking for signs that might hint at a future eruption. They will watch for changes in the shape of the ground below them, enabling scientists to issue an early alert if a volcano appears restless.
Some 1,500 volcanoes worldwide are thought to be potentially active, but only a few dozen are heavily monitored. One of these is Mount Etna where, last month, a BBC crew was caught up in a volcanic blast while filming a report on the new satellite project.
