- Providence Bay (Russian: Бу́хта Провиде́ния, Bukhta Provideniya) is a fjord in the southern coast of the Chukchi Peninsula of northeastern Siberia. It was a popular rendezvous, wintering spot, and provisioning spot for whalers and traders in the nineteenth and early twentieth centuries. Emma Harbor (now Komsomolskaya Bay) is a large sheltered bay in the eastern shore of Providence Bay. Provideniya and Ureliki settlements and Provideniya Bay Airport stand on the Komsomolskaya Bay. Plover Bay in English sources sometimes refers specifically to the anchorage behind Napkum Spit within Providence Bay (also called Port Providence) but was commonly used as a synonym for Providence Bay; Russian 19th century sources used the term for an anchorage within Providence Bay.

The Kermadec Plate is a long and narrow tectonic plate located west of the Kermadec Trench in the south Pacific Ocean. Also included on this tectonic plate is a small portion of the North Island of New Zealand and the Kermadec Islands. It is separated from the Australian Plate by a long divergent boundary which forms a back-arc basin. This area is highly prone to earthquakes and tsunamis.
