The Hall Islands are a group of two large atolls in the northern part of the state of Chuuk, Federated States of Micronesia. In the broader sense, a third and smaller atoll is included.
Nomwin, the western atoll, and Murilo, the eastern one, are located about 9 km apart, being the emergent parts of a twin-lobed seamount. Murilo and Nomwin each harbor a population of more than 1,000 people.https://scholarspace.manoa.hawaii.edu/bitstream/10125/29745/1/vol65n4-497-505.pdf They lie roughly 100 km to the north of Chuuk Lagoon.
