PRELIMINARY EARTHQUAKE PARAMETERS——————————— * Magnitude 1.0 * Origin Time 1927 AKST Jan 14 2022 2027 PST Jan 14 2022 0427 UTC Jan 15 2022 * Coordinates 20.5 South 175.4 West * Depth 1 miles * Location near the Tonga Islands RECOMMENDED ACTIONS——————-Actions to protect human life and property willvary within tsunami advisory areas. If you are in a tsunami advisory area; * 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 advisoryareas. If you are in a tsunami advisory area; * A tsunami with strong waves and currents is possible. * Waves and currents can drown or injure people who are in the water. * Currents at beaches and in harbors, marinas, bays, and inlets may be especially dangerous. * 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. ADDITIONAL INFORMATION AND NEXT UPDATE————————————– * Refer to the internet site tsunami.gov for more information. * Pacific coastal residents outside California, Oregon, Washington, British Columbia and Alaska should refer to the Pacific Tsunami Warning Center messages at tsunami.gov. * This message will be updated within 30 minutes.
