The underwater volcano Ahiy erupts in the Pacific Ocean

 There are many indications that the underwater volcano in the Northern Mariana Islands continues to erupt.

The Northern Mariana Islands is an administrative unit that has the status of an organized territory of the United States without legal personality. It is located in the western Pacific in the Mariana Islands, sharing it with Guam, north of the Carolina Islands. USGS scientists have been recording underwater acoustic signals indicative of underwater explosions for weeks and are now able to locate their source at Ahii Seamount, in the Pacific Ocean, approximately 6,100 kilometers west of Honolulu.

Ahiy is a volcano located in the Pacific Ocean, 18 km southeast of the island of Farallón de Pajaros, belonging to the Marian group. Ahiy is an underwater conical volcano, located 137 meters deep. If the suspicions are correct, the volcanic eruption probably started in mid-October. Vessels in this area are advised to avoid the area and exercise caution in the event of an eruption or its products, including steam, floating pumice, gases, etc., reaching the surface.

The Ahii Underwater Volcano is located at the northern tip of the Marianas and is only one of the few active underwater volcanoes that make up the Marianas active volcano chain that is the result of the western subduction of the Pacific Plate beneath the Philippines' sea plate.

Current sonar signals, likely from volcanic activity on Ahia, were picked up by sensors on Wake Island, almost 2,000 km away. The USGS plans to send a team to investigate whether the volcano is actually erupting or whether the signals could be due to shallow earthquakes near the surface.
