Beginning the 8th of June, Taal Volcano was observed to be more active than normal, and sometimes at night the crater was covered with a glare. From 17th to the 21st of July, subterranean noises were heard, and many witnesses in Talisay, a town located along the shores of Taal Lake some distant from Volcano Island, reported small balls of fire (apparently about in diameter) appeared periodically above the crater. These balls after reaching a considerable height burst into small fragments, some of which fell back into the crater and the remainder upon the exterior slope. This increased in activity and eruption of July 20 though is not accounted as an eruption of Taal Volcano based on the eruption history of Taal.
