There was another volcanic episode in the news this evening. Mt Etna has been active in Sicily for weeks but now, Mount Sinabung in Sumatra is back in the news too. It’s been blasting volcanic ejecta five kilometres into the sky for a few days. The ash rains back down as choking, abrasive dust. That might seem awful but it’s relatively good news if you live beside an active volcano on The Ring of Fire.
