Santiaguito volcano: emplacement of a viscous lava flow

The active Santiaguito lava dome (Guatemala) has been in a state of steady eruption for many years. Viscous lava is rising and accumulating in the active dome, as well as forming slow-moving lava flows. This time-lapse from satellite imagery shows the emplacement of a new lava flow on the SW side, reaching several km length over an interval of approx. 3 years compressed into 6 seconds.
