How exceptional was the 1994 heat wave?
The paper examines heat-related mortality in the population of South Korea between 1991 and 2005 and examines the extent to which the 1994 heat wave was unusual in terms of mortality impacts and recurrence probability. Most summer heat waves are found to be associated with enhanced mortality. However, the July to August 1994 heat wave was clearly exceptional, with the total death toll exceeding 3000 in South Korea. This value represents net excess mortality, as no displacement effect appeared after the hot summer season. Significantly elevated mortality occurred in all age groups, and an estimated 45% of victims were persons under 70 yr of age. The relative increase in mortality was larger in children up to 14 yr than in any other age group, and the mortality response was stronger in males than females, although males were less vulnerable during ‘average’ heat waves. The very large death toll ranks the 1994 heat wave over East Asia as among the worst weather-related disasters in this r
