Volcano San Miguel increases activity

As reported by the government agency MDMA, the volcano San Miguel in El Salcador increased its activity over the weekend and doubled its previous ejection heights of tephra. During particularly strong eruptions, the volcanic ash rose to 1100 m above crater level. The eruptions had a VEI of 1. Nevertheless, the eruptions were described as phreatic. Volcanologists report that they are closely monitoring the volcano’s activity and watching for indications of whether there is a transition to stronger phreatomagmatic eruptions.
