A shallow phreatomagmatic, or Surtseyan eruption from Kavachi volcano on 17 or 18 July 1977. Jets of dark ash can be seen emerging from white steam plumes. Numerous individual blocks ejected at high velocity are trailed by steam. Similar activity was observed from boats and airplanes for a period of less than one week.
