Between 1707 and 1731, the center of activity shifted from the Main Crater to other parts of Volcano Island. The eruptions of 1707 and 1715 occurred in Binintiang Malaki (giant leg) crater (the cinder cone visible from Tagaytay Ridge), accompanied by thunder and lightning. Minor eruptions also emanated from the Binintiang Munti crater on the westernmost tip of the island in 1709 and 1729. A more violent event happened on September 24, 1716, when the whole southeastern portion of the crater of (Calauit), opposite Mount Macolod, was blown out. Father Manuel de Arce noted the 1716 eruption killed all the fishes...as if they had been cooked, since the water had been heated to a degree that it appeared to have been taken from a boiling caldron. The 1731 eruption off Pira-Piraso, or the eastern tip of the island, created a new island.
