  1. I can not find documentation on the eruption in the period 1902-1904.
    Only the Caribbean eruption of the Pelee volcano.

    1. I am going to write an article about this activity later today. I am just waiting a little to see how this develops. I am not expecting any major change from what I’ve been seeing today.
