Volcano Calendar 2018: We're proud to present our 2018 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.
Since mid June, 2017, unrest at the volcano has gradually declined to levels considered as normal background or normal. ...more
The March 2016 eruption changed the configuration of the summit crater, such that it is slightly wider and has a more vertical orientation than before the 2016 eruption. Since then, the volcano has remained relatively quiet, although there was a brief period of elevated seismicity in early June, 2017 that resulted in AVO raising the Aviation Color Code to Yellow and the Alert Level to Advisory. Many satellite views of the summit are now able to detect elevated surface temperatures within the crater and upper part of the volcanic conduit most likely associated with the emission of hot gases.

Seismic activity at the volcano decreased after the small increase on 7 June, but the volcano continues to produce minor activity: steam emissions were occasionally observed from the summit crater. ...more
Satellite images showed an approximately 55 km-long steam plume drifting W on 14 June, and a thermal anomaly during 15-16 and 20 June. The Aviation Color Code remained at Yellow and the Volcano Alert Level remained at Advisory. (Smithsonian / USGS Weekly Volcanic Activity Report 14-20 June 2017) [less]
The volcano has been showing increased seismic activity over the past several days, and there might be minor eruptive activity occurring, as the Alaska Volcano Observatory noted: ...more
"... there has been an increase in low-frequency earthquake activity at Pavlof. Such increases are sometimes seen prior to eruptive episodes, however in other cases they decline without eruptive activity. "In addition, several short duration tremor-bursts have been observed today, and AVO received a pilot report of a possible ash cloud this afternoon. Infrasound data from local instruments on Pavlof and from a more distant network in Sand Point do not show any evidence of significant explosive activity. [less]
Tours to active volcanoes: Watching a volcanic eruption is one of the most impressive natural displays. We have a wide selection of tours to active volcanoes worldwide at different activity and difficulty levels.
