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