A satellite image showing Alaska’s Iliamna Volcano “ready to rumble" has sparked renewed interest in the snow-covered peak, just as scientists recorded a spike in earthquakes on its slopes.

The image, taken on June 10 by the Operational Land Imager (OLI) on NASA and USGS’s Landsat 8 satellite, captured the volcano days before it saw an increase in seismicity around 4:30 am local time on June 15.

An increase in seismicity means frequently occurring small earthquakes, according to a report by US-based magazine Newsweek which first reported the development.

“Initially, the earthquake rate was nearly continuous, with several earthquakes per minute," said the Alaska Volcano Observatory (AVO) in a post on its website, “but this has since slowed to a rate of about one earthquake per minute".
