Fishing villages in coastal Pakistan would need to respond quickly to escape a tsunami from nearby parts of the Makran Subduction Zone. A previous Makran tsunami, in 1945, took hundreds of lives in this coastal area. The majority of those fatalities took place along tidal creeks of the Indus Delta, where the parent earthquake was scarcely felt. Today, many of the Delta villages must be reached by boat, and telecommunication is difficult. These circumstances add to the challenge of their receiving timely warning of an incoming tsunami—whether it is the immediate natural warning from a felt earthquake or a subsequent official warning from government agencies. A study supported by Oxfam GB underscores this challenge. Ten remote coastal villages, each visited by the study team, were found to have limited links to official warning systems through landlines, mobile phones, and the Internet. Two cities, by contrast, have International Maritime Satellite Organization sirens that can be set off by satellite. In addition to technological solutions, partial remedies currently available include improved tsunami awareness, training about natural warnings, and land use informed by hazard assessments.
