Indonesia: Tsunami warning - Opinion

"Indonesia, the country most frequently impacted by tsunamis in the past century, should be sharing its experience with other at-risk countries and leading efforts to create a regional tsunami mitigation system that could effectively reduce future loss of life," writes Syamsidik, a research development manager at the Tsunami and Disaster Mitigation Research Center and a lecturer in the Department of Civil Engineering at Syiah Kuala University in Banda Aceh. He added: "Our early warning system must be thoroughly overhauled. Indonesia must take the lead on this issue and make upgrading its system a priority, adding tsunami buoys, siren towers and improved IT facilities in remote areas to support the system."
