US pins down volcano risk
After spending more than a year assessing 169 active volcanoes in the United States and the Mariana Islands, experts have identified the volcanoes that pose the greatest threat to people and property.
The US Geological Survey (USGS) report, issued on 29 April, also pins down what steps should be taken to fill the gaps in the current monitoring systems for those volcanoes.
“We know that many of the most damaging effects of eruptions can be mitigated if proper monitoring is in place,” says Marianne Guffanti, a volcanologist with the USGS, which is headquartered in Reston, Virginia. “That’s what this report is all about.”
