Volcano Calendar 2019: We're proud to present our 2019 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.
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.
The Auckland Volcanic Field directly underlies the largest city of New Zealand and consists of more than 50 basaltic cones, maars and lava flows. It covers an elliptical area of 29 (N-S) x 16.5 (E-W) km and has been active for the past 140,000 years, during which is has produced about 7 cubic km of mostly basaltic lava. The last eruption was as recently as about 600 years ago when the cone of Rangitoto Island was formed. About 20 eruptions have occurred during the past 20,000 years, suggesting an average recurrence interval of approx. 1000 years.
Since eruptions could (and likely will) occur again in the future, it is a considerable hazard to Auckland city, especially since the time between first signs (seismic swarms, ground movements, gas emissions) to an eruption could be relatively short (weeks to months).
Volcanic crisis at Sakurajima - updates: A strong earthquake swarm and increased inflation were detected in August 2015 and triggered authorities to raise the alert level, as volcanologists think that a larger eruption could follow. News and updates on the events can be found on this page.
