| Note: | Several episodes of strong minors (some with “granding”) throughout the day. Follow through (succession of more strong minors) and/or durations were not strong enough to start an eruption. There were strong series of minors at 0936-0946, 1301-1317, and 1859. At 1922-27, I made the note, "Concerted bursts seem like massive Mastiff depth charges." |
