Roundup of Global Volcanic Activity – New Activity for the week 9 November – 15 November 2022

Ahyi – Mariana Islands (USA) : On 15 November the USGS reported that hydroacoustic sensors at Wake Island began to record signals in mid-October that are consistent with submarine volcanic activity. A combined analysis of the hydroacoustic signals and seismic data from stations on Guam and Chichijima Island, Japan, suggest the source of this activity is at or near Ahyi seamount. Contrary to initial observations of there being discolouration on the water’s surface, a reanalysis of satellite imagery from 6 November showed no evidence of water discolouration at the ocean surface.

Ambae – Vanuatu : On 15 November the Vanuatu Meteorology and Geo-Hazards Department (VMGD) reported that at approximately 1300 satellite data showed a large sulfur dioxide emission from Ambae. Seismicity also slightly increased. Residents on the southern and northern parts of the island reported a strong smell of sulfur dioxide gas and heard explosions.

Kavachi – Solomon Islands :Satellite data showed distinct yellow-green discoloured water in the vicinity of the submarine Kavachi volcano on 2, 7, 12, and 22 September, 2, 7, 12, 17, and 27 October, and 1, 6, and 11 November.

Kikai -Ryukyu Islands (Japan) : JMA reported that minor eruptive activity continued to be recorded at Satsuma Iwo-jima, a subaerial part of Kikai’s NW caldera rim, during 7-14 November. White gas-and-steam plumes rose 600 m above the crater rim. Surveillance cameras observed nightly incandescence.

Space Events

Leonid Meteor Shower

The annual Leonid meteor shower will peak this week as Earth passes through the trail of icy, rocky debris left behind nearly 30 years ago by the comet Tempel-Tuttle. On Thursday (Nov. 17) around 7 p.m. EST, Earth will swoop near a particularly dense patch of debris, resulting in sightings of about 15 meteors per hour. On Saturday (Nov. 19), stargazers may have another chance to see the Leonids, when Earth may pass through a stream of debris left by the comet more than 300 years ago.
