Tsunami Advisory in Effect for; ALEUTIAN ISLANDS, Samalga Pass, Alaska (30 miles SW of Nikolski) to Attu, Alaska including the Pribilof Islands For other US and Canadian Pacific coasts in North America, the level of tsunami danger is being evaluated. Further information will be provided in supplementary messages. PRELIMINARY EARTHQUAKE PARAMETERS --------------------------------- The following parameters are based on a rapid preliminary assessment of the earthquake and changes may occur. Magnitude 8.0 Origin Time 1525 AKDT Jul 29 2025 1625 PDT Jul 29 2025 2325 UTC Jul 29 2025 Coordinates 52.2 North 160.0 East Depth 46 miles Location 315 miles SW of Bering I., Komandorski 80 miles SE of Petropavlovsk, Kamchatka FORECASTS OF TSUNAMI ACTIVITY ----------------------------- Tsunami activity is forecasted to start at the following locations at the specified times. FORECAST START SITE OF TSUNAMI ---- ---------- Alaska Shemya 1646 AKDT Jul 29 Adak 1746 AKDT Jul 29 Saint Paul 1906 AKDT Jul 29 OBSERVATIONS OF TSUNAMI ACTIVITY -------------------------------- No tsunami observations are available to report. RECOMMENDED ACTIONS ------------------- Actions to protect human life and property will vary 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 advisory areas. 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 60 minutes.
