The US Needs to Seriously Beef Up Its Volcano Monitoring

Bogoslof is mostly off the grid when it comes to volcano monitoring. It has no seismometers, no webcams, no real surveillance. Even now, after almost two months of eruptions, the Alaska Volcano Observatory relies on data from seismometers on other islands, reports from pilots and local residents, and remote sensing data from weather satellites to tell what’s happening at Bogoslof. This is far from ideal when you’re trying to keep people and property safe.

Ideally, seismometers and other instruments at the volcano would measure the small changes in volcanic tremor that can give the first hints of an eruption in the next days to minutes.
