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.
White Island in the Bay of Plenty ca. 50 km off the North Island's east coast is one of New Zealands most active volcanoes, well known for its spectacular crater with strong hydrothermal activity and sulphur deposits. It is part of the active Taupo volcanic zone and last erupted in 2001 (phreatic explosion).

Ash plume from White Island today seen on Nasa's Suomi NPP satellite
A small eruption occurred this morning from the volcano. Weak ash emissions were seen from the vent of the volcano's 2012 lava dome in the central crater; the alert level was raised from 1 (green) to 3 (orange). ...more
The eruption consisted in a phase of passive (without significant explosions) ash venting starting at about 11:50 local time. The activity produced a whitish-gray plume of fine ash that rose a few hundred meters and was blown by strong winds to the east where it formed a narrow plume several tens of kilometers long.
Geonet's instruments inside White Island covered with ash from the eruption on 27 April 2016 (image: Geonet)
A small phreatic explosion occurred inside the main crater of the volcano on the evening of 27 April around 21:50 local time, Geonet reported. The volcanic alert level was raised to 3 and aviation color code to Orange. ...more
Since the eruption, the volcano has returned to quiet / normal activity and the alert level was again lowered to 2 (although aviation color code remains orange for the time being as other explosions could occur). The eruption covered about 80% of the crater's surface and the northern and southern crater walls with fine ash. It had been preceded by a slight increase in seismic activity, but SO2 gas emissions had been unchanged. During a visit last week, it had been observed that the level of the acid crater lake had fallen by approx. 2 meters, indicating significant evaporation, and / or greater infiltration. [less]
