Indonesia– Anak Krakatau, a volcanic island in the Sunda Strait between the islands of Java and Sumatra in Indonesia, erupted on Tuesday sending columns of ash and rock hurtling high into the air. The rise in volcanic and earthquake activity prompted authorities to put in place a 2km exclusion zone for tourists and local fishermen. The Indonesian Volcanology and Geology Disaster Mitigation Centre reported that an estimated 6,000-7,000 volcanic earthquakes were recorded daily during the weekend and on Monday. Daily earthquake totals usually do not exceed 100-200. Seismologists are still attempting to determine the type and scale of the ongoing eruption. –IWO
