Eruption history
There have been six historical eruptions recorded from the volcano since the 18th century.
*1773: The first recorded submarine eruption from the volcano, on what was known as Didicas reefs of the Farallones.
*1856 September or October: The first activity started as a column of "smoke" in between the two rocks well known to the locals, but no earthquakes were felt.
*1857: The volcano erupted violently, attended by earthquakes, then broke the surface of the sea. From then to 1860, the volcano was constantly active and in four years had reached a height of . The island was later washed out by the waves and disappeared beneath the sea.

*1900: An eruption left three rock masses up to high.
*1952: The volcano broke the ocean's surface again during an eruption that started around March 16.
*1953: The activities subsided. The resulting island is wide with an elevation of .
*1969: First known fatalities from the volcano: three fishermen were killed while fishing near the volcano. The activity, which started on March 21, came from a new crater on the northern side of the island. Air reconnaissance over the volcano reported bubbling mud on the wide bottom of the crater. Activity on the volcano waned in June the same year.
*1978 January 6 to 9: The last eruption of Didicas to date. The mild eruption blanketed the island with fresh volcanic ashes.
