This volcanic eruption is one of the most incredible natural phenomena I've ever seen. The video was shot in Guatemala at 5:30 in the morning after an all night trek up the side of Santa Maria, a 12,375 foot high inactive volcano. The eruption of the very active Santiaguito, far below our vantage point, surprised everyone with how quickly it happened and how fast the ash plume rose. It will typically erupt every two hours or so so we did not have to wait long. Sorry for the shoddy camera handling.
