Puerto Rico has developed tsunami maps showing areas liable to flood and those that should be safe. They also tried a text message (SMS) system to send alerts, reports SciDevNet.
Alejandro De La Campa, director of the US Federal Emergency Management Agency’s Caribbean office, told SciDev.Net: “We hope never to have to use all the plans we made, to send the SMS we write or to relocate people in a rush.
“But it is like having fire insurance at home: it’s preferable not to use it, but you have to have it.”
