Yellowstone Webcam

This view of the Old Faithful Geyser is captured from a webcam inside the visitor education center. At this location, time is not measured by a clock, but by this geyser. Visitors make decisions on when to eat, take a tour, interact with exhibits or watch the visitor center film based on Old Faithful's next eruption. Staff post predictions for the next Old Faithful Geyser eruption on this webcam. If you want to catch a live, uninterrupted view of the geyser in action, check here first for the next prediction.Despite the myth, this geyser has never erupted at exact hourly intervals, nor is it the largest or most regular geyser in Yellowstone. It does, however, erupt more frequently than any other of the large geysers. The VolcanoCam image automatically updates approximately every minute.

YELLOW:	Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
ORANGE:	Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].
RED:	Eruption is imminent with significant emission of volcanic ash into the atmosphere likely OR eruption is underway or suspected with significant emission of volcanic ash into the atmosphere [ash-plume height specified, if possible].
