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 Craters of the Moon are located at the NW end of the largest lava field of the Snake River Plain in Idaho, USA. The volcanic field contains over 60 lava flows, 25 cinder cones up to 250-m high, and 8 eruptive fissure systems, and covers an area of 1600 km2.
The Craters of the Moon formed in 8 eruptive periods each lasting several hundred years, and separated by quiescence intervals of up to 3000 years. The eruptions began about 15,000 years ago, and ended with the most recent (so far) eruptions only 2100 years ago. In contrast to the Craters of the Moon, most other lava fields in the Snake River Plain formed during single, short eruptions.
On average, lava output rate was 1.5 cubic km/1000 years for the period 15,000 to 7,000 years ago and increased to 2.8 cubic km /1000 years for the interval from 7,000 to 2,000 years ago.
Krakatoa explodes: In the afternoon of 17 Oct, a particularly violent explosion occurred at Anak Krakatau, blasting away a portion of the southern crater rim. A similar event might have been the final trigger for the catastrophic landslide that let the cone collapse and cause a devastating tsunami on 22 Dec 2018.
