Ecuador's Reventador volcano eruption was caught spectacularly in time-lapse video by British volcano photographer Richard Roscoe.
Reventador is Spanish for "troublemaker." It is a little-known active stratovolcano in the Amazonian Andes of Ecuador, Reuters reported.
Roscoe and a German colleague captured the rumblings and fiery explosions earlier this month with wide-angle videos using moonlight alone by applying a unique filming technique at a specific rate, and sped up the video to show the activity over the course of a three-day period.
Reventador's last recorded major activity was in 2002, when a huge eruption occurred with almost no warning and its pyroclastic flow of gas and matter wiped out a nearby valley and damaged pipelines, Roscoe said.
Volcanologists say Reventador is undergoing another explosive phase with gas and lava spewing from vents in its summit.
