Abstract
The Iggeesund event is an example of the high seismicity which occurred in Fennoscandia during deglaciation as a function of the high rate of glacial isostatic uplift. This event is dated to varve 9663 BP. The Iggesund–Hudiksvall area is represented by intensive postglacial fracturing of the bedrock recorded over an area of, at least, 50×50 km. The most remarkable locality is the Boda cave system; a hill fractured into a field of large detached blocks with a cave system of more than 2 km length. In the varve-year 9663 BP, an extensive turbidite was spread over an area of 210×80 km. Liquefaction structures are recorded over an area of 80×30 km and can be assigned to the same varve year. Structures and deposits of a tsunami are recorded over 80×50 km
