Abstract
In the current context of climate change–induced warming, interest in ana lysing the impact of volcanic eruptions on the climate has renewed. The main
conclusions from related papers indicate that volcanic eruptions alter the ter restrial radiative balance and cause cooling in the years after an eruption:
known as “years without summer.” These episodes of cyclical cooling have
been related to negative socio-economic impacts (such as crop reduction, fam ine, and social unrest). However, the effect on precipitation has been studied
less. Detailed studies on the economic impact of large eruptions are scarce,
especially for historical eruptions. This study analysed the effects of the 1883
Krakatoa eruption on temperature and precipitation in the south-east of the
Iberian Peninsula and related economic and social effects. It was concluded
that this eruption incited a significant decrease in maximum temperatures and
stability, an increase in minimum temperatures, a decrease in average temper atures, and a significant increase in rainfall. This climatic context produced a
decrease in cereal prices and a reduction in climatic risks (droughts and frosts).
Therefore, the effects of the eruption of Krakatoa improved socioeconomic
conditions in the south-eastern Iberian Peninsula
