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.
Small ash emissions from the volcano have continued yesterday and in the night. Due to the hazard of new ash falls, the airport remains closed today and is scheduled to reopen tomorrow morning at 11:00 am local time. ...more
The Indonesian authorities keep the status level of the volcano at 2 (on a scale of 1-4, 4 being highest). No evacuations were ordered, but an exclusion zone of 1.5 km radius around the crater is in place. Ash falls were reported in several villages including Salero, Soa Sio, Sangaji, Dufa-Dufa, and in some parts of Central Ternate. Based on information from the local volcano observatory, the ash from yesterday's activity reached 1,700 to 2,500 meters above sea level. Seismic data show no significant earthquake activity associated with the activity, but a weak constant tremor signal. [less]
A small eruption occurred at the volcano this morning. An explosion created an ash plume that rose approx. 600 m above the crater. The Babullah airport of Ternate island was closed due to the ash plume and is scheduled to reopen tomorrow morning at 10:00 am. ...more
The nature of the eruption is unclear, but likely a phreatic event typical for Gamalama which last had similar eruptions in July, September and December last year. [less]
PVMBG reported that during 1 August-4 November seismicity at Gamalama fluctuated, and was dominated by hybrid earthquakes and signals indicating emissions. 3 periods of increased seismicity were recorded during 3-5 and 11-19 August, and 8-22 October, though seismicity declined overall. ...more
A sudden, small eruption from a fissure on the NW flank occurred at 19:53 on 8 September with no precursory seismicity, and produced a plume that rose 1 km. Gray plumes rose from 300-600 m the vent during 9-24 September. White plumes rose from Main Crater and fissures on the E and NW flanks as high as 200 m during 1 October-3 November. The Alert Level remained at 2 (on a scale of 1-4); visitors and residents were warned not to approach the crater within a 1.5-km radius. [less]

A new eruption occurred at the volcano this morning at 07:53 local time. An explosion produced an ash plume that rose approx. 1.5 km above the summit and drifted NE and dispersed quickly. The Ternate airport was temporarily closed. ...more
It is not clear whether the explosion was involving fresh magma or only phreatic in origin (driven by steam). The official alert level of the volcano remains at 2 (on a scale from 1 to 4) and an exclusion zone of 1.5 km radius around the summit is in place. [less]
On 4 August, BNPB reported that Gamalama continued to erupt, although with low intensity. Tremor was continuous. ...more
The Alert Level remained at 2 (on a scale of 1-4); visitors and residents were warned not to approach the crater within a radius of 1.5 km. The total number of evacuees in shelters was 1,791. Based on local observations, a SIGMET and wind data, and satellite images, the Darwin VAAC reported that an ash plume drifted over 20 km NW on 4 August. [less]
Several explosions during 18-19 July produced white-and-gray plumes that rose 300-800 m and drifted NW. A preliminary count of refugees showed there were 1,505 people (450 families) displaced by the eruption. Ash deposits were 1.5-6 mm thick in northwestern villages.
A phreatic explosion occurred yesterday (16 July) at 10 am local time, producing an ash plume that rose 1500 m. Ternate's airport was temporarily closed following the eruption. ...more
The eruption had been preceded by increasing seismic activity since late June. The alert level of the volcano remains at 2 (waspada) on a scale of 1-4, but VAAC Darwin raised the aviation color code to "orange". An exclusion zone of 1.5 km around the summit is in place. [less]
Intermittent ash emissions continue from the volcano. As it is unknown whether the eruption will dwindle down or increase, an exclusion zone of 2.5 km radius around the summit is in place. ...more
All persons that had been missing immediately after the eruption have been found, fortunately there were no victims, only 4 injured (by falling during escape). Ash fall has been causing small problems in Ternate where over 45,000 dust masks were distributed. The airport is still closed. [less]

The volcano, one of the most active in the region, erupted unexpectedly last night (Thursday evening, 22:41 local time). ...more
Unfortunately, it seems that the eruption claimed at least some victims: Several people (10-12 according to varying news reports) were on the volcano, a popular hiking destination, when the initial explosion occurred at night. At least two of them were reported missing, presumably killed, and several others wounded, mainly from injuries suffered when falling during their escape. Explosions and ongoing ash emissions continued throughout Friday and produced ash plumes that drifted eastwards, caused ash fall at the Ternate airport which had to be shut down. More than 5 cm of ash covered the runway and some parked aircraft.

Two separate explosions occurred at Gamalama volcano on Ternate Island yesterday at 13.22 and 14.15 local time. The eruption followed an increase in seismic activity and triggered PVMBG to raise the alert level to 3 (out of 4) "Siaga". According to the newspaper Liputan6 people have not heard the explosion, but only saw an ash plume rise. ...more
The new activity comes less than a year after the volcano's previous eruption, when lahars (mud flows) had claimed several victims. Some people were panicking, but the situation remained otherwise calm in Ternate. The city has received some ash fall which led many shops to close, and some of the inhabitants started to wear face masks. [less]
CVGHM lowered the Alert Level for Gamalama from 3 to 2 (on a scale of 1-4) on 24 January based on visual observations of white plumes rising as high as 100 m above the crater and a decrease in seismicity since the last eruption on 23 December 2011. ...more
At least 3 people were killed by mud flows. 1,000-2,600 more were evacuated from several villages on 27-28 December, when heavy rainfall turned fresh ash deposits into devastating mud flows. Most damage was in the villages of Tubo and Tofure and along the Togorara and Marikurubu rivers.
Eruptions are continuing at Gamalana volcano, consisting of moderate to strong ash explosions, as observed by our correspondant on location. Volcanologist Mr Kristianto, head/coordinator of all observatory post in eastern Indonesia, reports 4 explosions on 4 December and numerous volcanic earthquakes. The daily status update reads: ...more
- Tremors occuring continuously with amplitudes of maximal 0,5 - 2 mm ( recorded on the seismograph) - Volcanic earthquake : 52 times
Mount Gamalama volcano in Indonesia's remote North Maluku province erupted at 23:00 local time on Sunday (1400 GMT), according to local news. The eruption produced small amounts of ash, causing local electrical blackouts and ash fall in the provincial capital city of Ternate. ...more
There are reports of damage or fatalities. According to the news, some people from nearby villages have evacuated to safer locations, while a number remained at their homes. No ash seems to be visible on satellite imaginary: the VAAC Darwin has not issued any advisories, suggesting that the eruption is small. On the other hand, ash is difficult to detect in tropical areas with heavy cloud cover.

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.
Volcano Special Tours: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
