Summary

Mud volcanoes are often pictured as dramatic geological phenomena featuring the sudden eruption of large volumes of fiery mud in short, powerful bursts. By examining recent activity at the Lokbatan mud volcano in Azerbaijan, an international team of researchers led by the University of Oslo has found that many eruptions are relatively small and short-lived, producing only modest amounts of material near the crater. Instead of building large flows all at once, these outbursts seem to "wake up" much older mud deposits that were already sitting on the slopes.
