World’s biggest active geyser erupts at Yellowstone National Park for third time in weeks
Increased activity at Steamboat Geyser after three years sat dormant
The world’s largest active geyser has erupted for the third time in less than six weeks.
Steamboat Geyser, in Yellowstone National Park, erupted at around 6.30am local time on Friday morning, geologists said.
The eruption is the latest event in a rare period of activity at the geyser this year, following similar water discharges on March 15 and April 19 this year.
Before this year, Steamboat had not erupted since September 2014.
The US Geological Survey said all events so far in 2018 had been smaller than recent major activity observed in 2013 and 2014.
