The first of several major eruptions of Irazú between 1963 and 1965 took place on 13 March 1963. These eruptions produced heavy ashfall over much of central Costa Rica, severely affecting agricultural areas and causing major economic problems. Lahars caused fatalities and destroyed hundreds of houses.
