The following is additional information obtained by the RNZAF from the crew of the aircraft that flew over Matthew Island on 27 November.

During the overflight, the volcano emitted a gray dust cloud that merged with a layer of stratus clouds (held to about 350 m altitude by a temperature inversion). A strong sulfur odor was present in the area. Muddy gray discolored water was carried SE by the current. Because of poor weather and light conditions, no photographs were taken. More recent information on the activity is not available.

Geologic Background. Isolated Matthew Island is composed of two low andesitic-to-dacitic cones separated by a narrow isthmus. Matthew Island was discovered in 1788 by a ship captain, who named the island after the owner of his vessel. Only the triangular eastern portion of the small, 0.6 x 1.2 km wide island was present prior to the 1940s, when construction of the larger western segment began; it consists primarily of lava flows. The 177-m-high western cone contains a crater that is breached to the NW and is filled by a lava flow whose terminus forms the NW coast.
