The legendary Molucca Sea, known for its precious spices that attracted early traders from Europe, is not only one of Indonesia's most interesting and beautiful areas. It also has the largest density of active volcanoes of any region in Indonesia, thanks to a very complex and unique tectonic setting.
Two active subduction zones to the west and east have consumed a small oceanic microplate, the Molucca Sea plate, producing two active volcanic arcs in North Sulawesi and in Halmahera. On this tour we visit no less than 5 of the most active volcanoes in the world, two of which - Dukono and Ibu - have been in near permanent activity for years while the others, Lokon, Soputan and Karangetang erupt frequently.
Each of the volcanoes is completely different in character and provides a great adventure to explore. The tour for a small group is an immersion into colorful cultures and an intense meeting with its very friendly people. Last but not least, the delicious, spicy cuisine of the region will enchant you.

"...an amazing experience....high on the adventure scale with lots of unforgettable memories."

Greetings folks,
Here is a summary of my latest and last adventure of 2019. It's a little long this time but I hope you will find it interesting.

I returned to Indonesia (my previous trip was in 2013) to explore some more volcanoes, this time in north Sulawesi and north Maluku. In between exploring the volcanoes, there was time for some sightseeing in Tomohon and surrounding area (visiting geothermal areas, Tongkoko national park) and Ternate. On the way back I had a 2 day stopover in Singapore (my first time in the city).

In total the exploration involved 6 active volcanoes:
The first 3 volcanoes, Lokon, Mahawu and Soputan (all stratovolcanoes in north Sulawesi) were quiet at the time of our visit apart from fumarolic acitivity in the crater of Lokon, depositing sulphur around the vents. The craters of all 3 volcanoes were impressive with excellent views of the surrounding areas. Mahawu last erupted in 1977, whereas both Lokon and Soputan had last erupted more recently, 2015 and 2018, respectively.

The other 3 volcanoes are in North Maluku and were erupting at the time of our visit:

1. Karangtang. A stratovolcano with 2 main craters, is located on Siau island (central Sangihe Islands) and is reached by an approx. 5h journey by ferry from Manado. We spent 2 nights observing gaseous basaltic lava flows from the south crater. On the first night we were camped out in a field in Hiung village and although the lava flows were only observed from the south crater (largely on the right flank), you could see a glow from the north. On the second night, we went higher up (a steep hike up from Winangun village) to observe the activity from a closer distance. The volcano was more active on the second night. We no longer saw the glow from the north crater, but the activity from the south crater had increased substantially, with lava flows on both flanks at times, and sometimes running down the middle in the direction where we were (but we were still a safe distance away!).

2. Dukono. A complex volcano located on the north western side of Halmahera. The volcano has been almost continuously erupting since 1933 - mixture of degassing, ash eruptions and strombolian activity from the vents in the crater shooting lava bombs high up in the air. The 3h hike up to the base of the crater (our campsite) was tough. The area was quite surreal and covered in ash. The volcano was continuously degassing (at times accompanied by ash eruptions) from the time we arrived. We set off at 2am to cautiously approach the rim of the crater and as we got near, put on the necessary safety equipment (goggles, helmet and gas mask). Peering down into the crater, we could see the glowing vent (as a guess about 150-200m down) and some strombolian activity . Although I tried, I was unable to get any decent footage of the activity due to the gases constantly disrupting the focussing of the camera and the fact that I was wearing safety goggles (making manual focussing difficult). However, simply peering down at the glowing vent, going in and out of view with the gasses passing over it, was really a sight to behold!

3. Ibu. Ibu is also a stratovolcano and it took us 4-5 hours to trek up the rim of the crater from where the vehicles dropped us. The hike was on a good, but at times a steep trail. As we approached the crater rim we came across some andesitic lava bombs from the 2018 eruption near the trail. We set up camp on the crater rim, looking across to the lava dome, which at relatively frequent intervals, belched out huge clouds of steam and ash, at times explosively sounding like an aeroplane taking off. At night you could see the glow of the lava bombs being emitted, and at times lightening during strong ash eruptions. On the first night, I briefly went to sleep in my tent but was woken up shortly after, at about 1.30 am, by the ground and the tent shaking from side to side. Although it seemed like a long time to me, I guess this was very brief (a few seconds). Apparently, the shaking was due to a 7.1 magnitude earthquake (depth of 45km) that occurred in the Molucca sea on or near the sub-ducted Halmahera plate and the overlying Sunda plate. The epicentre was approx 138km east of Bitung and approx. 150km west from where we were. Minor shakes (barely detectable) continued at intervals throughout the night and the next day. Although I had experienced similar earthquake shakes when young in Mbeya, Tanzania (the place where I was born and which is close to the African Rift valley), I must admit that this was a bit of a scary moment. On the second night, there was quite a lot of fog obscuring the view of the eruptions and so I took the opportunity to get some sleep. Which was just as well since at some point during the night, the wind had changed direction and the ash clouds instead of blowing away from the campsite, were now blowing directly above us. Ash rained down on the tents a few minutes after each eruption. Walking up the crater rim a little further you could look down across to the lava dome. It may be just my imagination, but the lava dome appeared to have grown a little over the time we were there and may be continuing to grow possibly leading to a big explosive eruption in the future!
Overall this trip was an amazing experience....high on the adventure scale with lots of unforgettable memories (like experiencing an earthquake whilst camped out on an active volcano). These volcanoes are some of the world's most active and I would like to acknowledge our guide and volcanologist, Andi Rosadi (who also cooked at the campsites), who made it possible for us to get up close and personal with them. Andi has a lot of experience of these volcanoes and is very familiar with their characteristics to know when, where and how to approach them safely. The trip was very well organised and the logistics were flawless.

My 2 day visit to Singapore was good but far too short as there are lots of attractions to cover. Those of you who have already been there will know that it is a vast contrast to most other cities in that it's clean, safe, controlled (for example you are not allowed to eat or drink in station concourses or trains) and efficient. The metro stations and the trains are air conditioned and offer respite from the hot humid conditions outside. I particularly enjoyed the gardens by the bay and the walk along the Singapore river to the bay, and of course, I couldn't come away without sampling the rather expensive but infamous Singapore Sling at the Raffles Hotel.

With best wishes, Jay

"...one of the impressive, organized tours I had take part in" (Jens-Wolfram E., about the Volcanoes & Spices tour)

Dear Tom, dear Irina,
returned at the mid of week from Indonesia, I'd like to give you a very positive feed back from our Tour "Volcanoes & Spices". Our indonesian guide, Andi Rosadi, and his team with Donald, John and all the other supporter and helper had made this journey to one of the impressive, organized tours I had take part in. We enjoyed not only an Adventure to visit some of the most active volcanoes in this region, we also were very happy to be with a real optimistical, engaged and enthusiatical guide who tried to feed us besides the expeditions - with the best meals Indonesia has to offer. Andi – one of the experts with best connections to his colleagues in this country - has had always an open ear to the problems of every member in the group and he was able to manage even the problems arising when people of vary different physical Fitness have the only dream: To be as close as possible to the „beasts“…

After the tours with „Volcanoes Discovery“ I traveled to the South in Sulawesi and from there to the Toraja-Area where an acquaintance of him showed me many interesting secrets like the rock graves not only in the touristic areas.

Dear Tom, dear Irina,
have again many thanks for this trip.
I wish you a great Christmas time and the best for 2020.

"...the trip was wonderful ..." (Volcanoes and Spices tour)

"Hello dear Ingrid and Tom,
Return in Manado and feedback: the trip was wonderful and all was perfect. Andi is a fantastic guide.
Kind greetings
Siegfried"
(Siegfried N., Germany, about the Volcanoes and Spices tour in July 2018)

"I had an absolutely fantastic time with Andi, Donald and Thomas"

"Hi Tom

... the trip was perfectly tailored, providing time off between hard treks to recover and enjoy beaches, countryside and markets. The volcanoes were awesome and he explained their particular "personalities" very well.

Andi and Donald both worked extremely hard to ensure that everything ran smoothly for us. I appreciate the difficulties involved in organising reliable porters, drivers, food and accommodation and Andi always managed to keep us on schedule. He went beyond his brief and helped me enormously with my photography, even taking me shopping for essential accessories that I had omitted to bring with me.

On each camping expedition I was the only female with approximately eight men in an isolated area and I never felt uncomfortable, but on the contrary, I felt extremely safe and protected. I had an absolutely fantastic time with Andi, Donald and Thomas and would not hesitate to recommend the trip to anyone who felt they were fit enough to tackle Ibu and Dukono.

Best wishes
