'Stunning' tsunami record discovered in Indonesia cave
JAKARTA (AFP) - Scientists said on Friday they have discovered a cave on the Indonesian island of Sumatra that provides a "stunning" record of Indian Ocean tsunamis over thousands of years.
They say layers of tsunami-borne sediments found in the cave in northwest Sumatra suggest the biggest destructive waves do not occur at set intervals - meaning communities in the area should be prepared at all times for a tsunami.
"It's something that communities need to know," research team leader Charles Rubin told AFP, adding that the team wanted to "promote safety of coastal communities".
Professor Rubin and other researchers from a Singapore institute were working with scientists from an Indonesian university when they discovered the cave, south of Banda Aceh, the capital of Aceh province.
