(Indonesia tsunami) No-go area extended to three milesWorld | 27 Dec 2018 1:32 pm
Indonesia today widened the no-go zone around an island volcano that triggered a tsunami on the weekend, killing at least 430 people in Sumatra and Java.
The volcanology agency raised the Anak Krakatau volcano's alert status to the second highest and more than doubled the exclusion zone to a 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 6 1/2 feet. The government has warned Sunda Strait communities to stay less than a mile away from the coastline because of the risk of another tsunami.
Heavy rains and high seas have hampered the search and effort. Some bodies were found at sea and at least 159 are missing.
Radar data from satellites, converted into images, shows the Anak Krakatau volcano is dramatically smaller following Saturday's eruption.
Satellite photos are not available because of cloud cover but radar images from a Japan Aerospace Exploration Agency satellite taken before and after the eruption show the volcano's southwestern flank has disappeared.
Dave Petley, head of research and innovation at Sheffield University who analyzed similar images from a European Space Agency satellite, said they support the theory that a landslide, most of it undersea, caused the tsunami.
"The challenge now is to interpret what might be happening on the volcano, and what might happen next,'' he wrote in a blog.
