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.
VolcanoAdventures: Depuis 2005, VolcanoDiscovery propose des voyages en petits groupes, des randonnées et du trekking, ainsi que des expéditions pour voir des volcans actuellement en activité, des voyages photographiques dans de nombreuses régions d’activité volcanique à travers le monde.
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.
Manam volcano located 13 km off the northern coast of New Guinea near Bogia town is one of Papua New Guinea's most active volcanoes. It has one of the longest records of historic eruptions in the SE Pacific region. The larger eruptions of Manam produce pyroclastic flows and sometimes lava flows. Both have repeatedly reached the coast and affected populated areas.
A large series of eruptions began at Manam in November and December 2004. It forced evacuations from the whole island. A pyroclastic flow at Manam volcano on 3 December 1996 killed 13 people in the village of Budua.

Manam volcano news and eruption updates (New Guinea):
Heat signals from Manam volcano (MODIS data / Univ. Hawaii)
The volcano is currently in an elevated phase of activity. Near-continuous ash emissions have been observed today, generating a plume visible on satellite imagery extending more than 50 km to the ESE. ...plus
In addition, a very strong heat signal was detected by the moderate-resolution imaging radio spectrometer (MODIS) sensor aboard some of NASA's satellites. This heat signal could be caused by the presence of active lava flows, a strongly active dome, or - most likely - hot pyroclastic deposits following a strong vulcanian-type explosive eruption, which is also suggested by the information in local press articles and the distribution of the heat signals scattered around on the flanks of the volcano. Ash fall was reported in Dugulava village on the northeast coast of the island. According to local reports, the explosion on Tuesday (16 May) was heard tens of kilometers away and lava and flames was seen erupting from the crate, and lava was seen "rolling down the southern side of the volcano" (this could be a lava flow or a pyroclastic flow).
The Rabaul Volcano Observatory reported that another phase of strombolian activity began at the southern crater on 4 May at around 17:00 local time. ...plus
RSAM values increased to 100-150. A sharp increase in values was detected at 03:30 on 5 May, though the highest RSAM value (1,400) occurred between 05:00 and 06:00. RSAM dropped rapidly to 200 by around 07:00, and then by 14:00 RSAM values were around 50. (Source: USGS Weekly Volcanic Activity Report 3-9 May 2017) [moins]
Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
Top 20 quakes in 2016: Several magnitude 7 quakes occurred in 2016 (but none above M8): Papua New Guinea, NZ, Ecuador, Solomon Islands, Sumatra, Chile, Alaska and others - nearly all major earthquakes were located near active subduction zones.
See the top 20 list of largest quakes in 2016 with this map.
