RECOMMENDED ACTIONS ------------------- Actions to protect human life and property will vary within tsunami warning areas. If you are in a tsunami warning area; * Evacuate inland or to higher ground above and beyond designated tsunami hazard zones or move to an upper floor of a multi-story building depending on your situation. * Move out of the water, off the beach, and away from harbors, marinas, breakwaters, bays and inlets. * Be alert to and follow instructions from your local emergency officials because they may have more detailed or specific information for your location. * If you feel a strong earthquake or extended ground rolling take immediate protective actions such as moving inland and/or uphill preferably by foot. * Boat operators, * Where time and conditions permit, move your boat out to sea to a depth of at least 180 feet. * If at sea avoid entering shallow water, harbors, marinas, bays, and inlets to avoid floating and submerged debris and strong currents. * Do not go to the shore to observe the tsunami. * Do not return to the coast until local emergency officials indicate it is safe to do so. IMPACTS ------- Impacts will vary at different locations in the warning areas. If you are in a tsunami warning area; * A tsunami with damaging waves and powerful currents is possible. * Repeated coastal flooding is possible as waves arrive onshore, move inland, and drain back into the ocean. * Strong and unusual waves, currents and inland flooding can drown or injure people and weaken or destroy structures on land and in water. * Water filled with floating or submerged debris that can injure or kill people and weaken or destroy buildings and bridges is possible. * Strong and unusual currents and waves in harbors, marinas, bays, and inlets may be especially destructive. * Some impacts may continue for many hours to days after arrival of the first wave. * The first wave may not be the largest so later waves may be larger. * Each wave may last 5 to 45 minutes as a wave encroaches and recedes. * Coasts facing all directions are threatened because the waves can wrap around islands and headlands and into bays. * Strong shaking or rolling of the ground indicates an earthquake has occurred and a tsunami may be imminent. * A rapidly receding or receded shoreline, unusual waves and sounds, and strong currents are signs of a tsunami. * The tsunami may appear as water moving rapidly out to sea, a gentle rising tide like flood with no breaking wave, as a series of breaking waves, or a frothy wall of water.
