Abstract
Fast-rising jökulhlaups from the geothermal subglacial lakes below the Skaftá caul-
drons in Vatnajökull emerge in the Skaftá river approximately every year with 45
jökulhlaups recorded since 1955.
The accumulated volume of flood water was used to estimate the average rate of
water accumulation in the subglacial lakes during the last decade as 6 Gl

vent and the margin of the lava can go up to 10 km/hour depending on slope.
Usually the transport time is shorter, but if the slope gradient

are estimated as the average of the
standardized individual series.
Data
Long-term series of temperature (49 stations),
precipitation (72 stations) and runoff (64 stations)
were used for composition of regional series in the
Baltic countries.
Regional series were developed on monthly,
seasonal and annual bases. All series were
normalised with reference period of 1961-1990.
