| Comments: | 1915 was the exact start time, witnessed by over a dozen gazers. Eruption started on the fifth of a series of very strong minors over a period of about 12 to 15 minutes, each minor increasing in volume and height. Observed times for minors 2, 3, and 4 prior to the eruption were at 1906, 1908, and 1912. I did not get an exact time for minor #1 and estimated that it started sometime between 1900 and 1903. |
