The Bali provincial government has planned to install four more tsunami detection sirens on the south coast of the island in 2013.
“We propose the addition of four tsunami sirens on the south coast of Bali. Hopefully, the funds for the purchase of these sirens will be allocated from the regional budget (APBD) for 2013,” Head of Bali Regional Disaster Mitigation Agency (BPBD) Dewa Made Indra said here.
He noted that currently there were six tsunami sirens in Bali, one each at the beaches of Sanur, Tanjung Benoa, Kuta, Seminyak, Nusa Dua, and Legian.
“These six tsunami sirens have been installed in the south coast of Bali because of the existence of a fault in the earth’s crust between the Indian Ocean and the area,” Indra explained.
“Moreover, the area is densely populated,” he added.
The four proposed tsunami sirens will be placed at several spots in the south coast of Bali, one at Gianyar, one at Klungkung, and two in Tabanan.
“If there is a tsunami coming, the siren will go off and it can be heard for up to two kilometres. Considering the fault in the earth’s crust below the Indian Ocean, the tsunami waves would arrive within 30 to 40 minutes,” Indra noted.
“So, people will still have the time to save their lives,” he said.
Indra stated that the south coast of Bali needs at least 15 tsunami sirens, but the north coast does not need as many because of its geographic location.
“The north coast of Bali has different geological characteristics, so it has different requirements,” he added.
