The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Michael volcano is a young and frequently active stratovolcano dominating the glaciated Saunders Island, located in the center of the South Sandwich Islands.
Mt Michael volcano has a 700 m wide summit crater that often contains a lava lake, but due to its remote location, most information is obtained by satellite imagery which often show a thermal anomaly at the crater.
Saunders Island was discovered by Cook in 1775 and named after Sir Charles Saunders, First Lord of the British Admiralty. The first landing on the island was probably in 1908 by C.A. Larsen. In 1937 an expedition from the ship Willian Scoresby landed in the area of Cordelia Bay.
A new eruption is likely underway at the remote volcano (also called like the whole island, Saunders). Since mid October, prominent heat signals coming from the summit of Michael cone can be retrieved on satellite data, but there are no direct (visual or other) observations. ...more
There have been no reports of ash emissions (so far) which implies that the activity is probably minor (small lava lake, strombolian-type explosions ?). [less]

One of the remotest active volcanoes is in eruption again. In a satellite image from 26 August 2015 obtained from the NASA's Earth Explorer program, the east flank of Mount Michael volcano can be seen stained grey which strongly indicates that an eruption took place.
