John Neal and Amanda Swan Neal of Mahina Expeditions bluewater voyaging school have weathered a few earthquakes and tsunamis in their decades of teaching others aboard their Hallberg-Rassy 46 sailboat, Mahina Tiare III. In the wake of the 2009 tsunami on Samoa, they devised an earthquake/tsunami awareness and response system that they now include in the Mahina Expeditions curriculum. With the goal of helping other sailors, the Neals allowed Practical Sailor to post this strategy.
