Sarah Henton observes the 1-minute-long interval of vigorous upwelling at Upper Klawasi mud volcano. The upwelling reaches a height of about 1 meter above the pool level. Water/mud this day was 26.9°C, exactly what it measured in the summer of 2005. Also see image #32182, and #32222 for the appearance during the 6-7-minute non-vigorous interval.
