The 1677 eruption of La Palma, Canary Islands
The 1677 volcanic eruption, located close to the town of Fuencaliente at the south end of La Palma, has been associated with the large voleanic cone of San Antonio, an emission centre showing relatively high energy phreatomagmatic phases. However, detailed geological mapping and a reinterpretation of available eye-witness accounts clearly prove the San Antonio emission centre to be a preexisting volcano related to an eruption that occurred several thousands years earlier. The 1677 eruption, or Volcán de Fuencaliente is a low magnitude eruption composed of a small strombolian vent and a cluster of aligned spatter vents. About 75-125 x 106 m3 of lavas from these spatter vents covered an area of 4.5 x 106 m2 and formed a wide coastal platform with 1.6 x 106 m2 of new land gained from the sea. This modest magnitude eruption is in better accord with the negligible damage caused to the arca reported in the contemporary accounts. This revision of the 1677 eruption and its magnitude is relevant for the precise reconstruction of the recent volcanism of La Palma and the correct definition of volcanic hazards in the island.
