Volcanic Activity
On January 4, 1641, a volcanic eruption covered much of Mindanao in darkness and sent showers of ash as far as Cebu and Panay. It was reported at the time as being from a small island "opposite the main river of Jolo" and the only possible source of eruption in Jolo is Mount Dakula near Lake Panamao. From recent studies, the eruption was finally attributed to Mount Parker in South Cotabato.
A tsunami occurred in 1897, believed to have been caused by a local submarine eruption on 21 September 1897. It is possible this eruption was centered at Lake Seit, a volcanic maar with still active solfatara.
Volcanoes in the Jolo Group are young and considered active on the probable eruptions above.

Famous quotes containing the words volcanic and/or activity:
“Pity the planet, all joy gone
from this sweet volcanic cone;”
—Robert Lowell (1917–1977)
“The mob is man voluntarily descending to the nature of the beast. Its fit hour of activity is night. Its actions are insane like its whole constitution. It persecutes a principle; it would whip a right; it would tar and feather justice, by inflicting fire and outrage upon the houses and persons of those who have these. It resembles the prank of boys, who run with fire-engines to put out the ruddy aurora streaming to the stars.”
—Ralph Waldo Emerson (1803–1882)
