Carita: Indonesia raised the danger level for an island volcano that triggered a tsunami on the weekend, killing at least 430 people in Sumatra and Java, and widened its no-go zone.
The country's volcanology agency said on Thursday that the Anak Krakatau volcano's alert status had been raised to the second-highest level and the exclusion zone more than doubled to a 5-kilometer (3-mile) radius.
The eruption on Saturday evening caused part of the island in the Sunda Strait to collapse into the sea, apparently generating tsunami waves of more than 2 meters (6 1/2 feet). Most tsunamis are caused by earthquakes.
The government has warned communities in the strait to stay a kilometer (6/10 of a mile) away from the coastline because of the risk of another tsunami triggered by Krakatau's eruptions. A navy vessel is expected to pass by the island later Thursday, which could give scientists more information about the risks of a second collapse.
