| Comments: | "Electronic data showed an abrupt pool water temperature rise from about 110 F to 119 F followed by a rise to 123 F by about 1200. Soil temperatures rose about 5 F at the spike then about 2 F by 1200. Another spike in pool temperatures ranging from 110 F to 114 F occurred at about 1838 with a corresponding rise and fall in soil temperatures of about 2 F. Black Diamond appeared to have erupted. All loggers and attendant cover rocks were intact with thermistor #2 still in the pool. New black and white rocks were blown to the southwest of Black Diamond Pool. Pool temperature 8 feet from the bank was 111.6 F {44.1 C}." This eruption was marked as questionable in the original report but in my opinion this is enough evidence that an event took place. |
