Jolo Group - Volcanic Activity

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)

    In communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have a mind, without ever becoming hunter, fisherman, shepherd or critic.
    Karl Marx (1818–1883)
