Balos is a small bay and beach on the caldera side near Akrotiri. It can be accessed from a trail leading down from the caldera rim above or following the coast, starting at the caldera beach with its access road. Both can be combined to a highly interesting short round trip of about 1-2 hours.
It is one of Santorini's least crowded and best places to swim inside the caldera. Until today, it is also used as a small harbor and boat shelter, as well as a famous place to collect capers. Most likely, the Balos Bay was already used as harbor in Minoan times. Remnants of Minoan building had been found on the cliff above during the 19 and 20th centuries (but unfortunately construction and erosion have by now destroyed most of it).
Geologically, it is also of particular interest: along the coast, the cliffs expose an old basaltic-andesitic cinder cone in cross section where a transition from water-magma interaction (phreatomagmatic activity) to purely strombolian-type eruptions (magmatic activity) is brilliantly recorded.

Before going to Fira for our caldera hike to Oia during our geologic walking tours, we decided to make an additional stop in the traditional village of Vothonas, one of the most scenic and still largely untouched-by-tourism on the island. It is located at the feet of the northern slopes of the Pirgos hill. It had developed from cave-house settlements in the area where several of the large characteristic pumice canyons meet to a form a broad valley. Besides an excellent place to study the traditional cave-house architecture, it offers excellent outcrops of the massive pumice layer from the 1600 BC eruption. (Photo: Tom Pfeiffer)

Normally, our last excursion during the geologic walking tour leads us to the non-volcanic basement, which forms the highest mountain Profitis Ilias and its neighbor Mesa Vouno, where the Ancient Greek city of Thera was located and whose excavated ruins are certainly a highlight that should not be missed during a visit to Santorini.
Spectacular views, very interesting geological formations, and - in spring - extraordinary spring colors by the rich flora, wait for you. (Photo: Tom Pfeiffer)

Another excursion during the geologic walking tour is the 12 km hike from Fira to Oia, a classic walk considered one of the best and most scenic hikes in the world and one of particular geologic interest as well. It leads through the elegant streets of Fira, Firostefani, Imerovigli and Oia as well as old mule paths, and for most of the time offers breathtaking views over the northern caldera of Santorini, which was the site where the violent Minoan volcanic eruption around 1600 BC took place and reshaped the island forever.

Normally, our first excursion during the geologic walking tour, we visit the area of the oldest volcanic rocks of Santorini found in the SW peninsula near Akrotiri and the lighthouse. It is a very varied walk along beaches, the caldera, through fields on old, mostly forgotten trails and mule tracks. Geologic highlights include spectacular submarine tuffs and lava domes, often with fantastic hydrothermal alterations. (Photo: Tom Pfeiffer)

Some impressions of our 'Desert, salt and volcanoes' expedition to Erta Ale and Dallol from 13 to 26 January 2018 - all images taken by participant Anastasia Ganuschenko. The new fissure eruption site which opened up on Erta Ale's flank a year before is still very active; now that some of the early lavas cooled down one can get very close to some of the lava lakes and hornitos that are still active. And thanks to the rainfall that finally came after about 4 years of drought the colourful scenery with salt deposits, acid lakes and small geysirs at the hydrothermal site of Dallol was once again looking its best!

Besides the 14-days tour group departures that we organise to this destination from mid November through to mid March we also offer customised tours at chosen dates for small groups and individuals. Please contact us through email for more information on such private expeditions to Erta Ale and Dallol! (Photo: Anastasia)

Upon request we organised a privately guided 3 days geology tour on the island of Santorini from 8 to 10 February 2018 of which tour guide and geologist Dr Ingrid Smet compiled this selection of photographs.
The islands looked very different from summer time when they are overrun by tourists and the heat has dried up most vegetation. Although the weather is of course less sunny and with higher chances of rain and clouds - and strong winds which sometimes result in the cancellation of all flights - it is well worth visiting Santorini in the winter time to take in the unique and quiet atmosphere and see the colourful winter and early spring flowers...

For many years now we organise 8-9 day group tours to Santorini both in autumn and springtime (Fascination Volcano tour) but if you can also contact us for a private multiple day tour at any custom date. (Photo: Ingrid Smet)

This photo diary is a compilation of images from different participants on our 12 - 18 April 2017 Kilauea Volcano Special guided by geologist Ingrid Smet. It also includes photographic documentation of the unofficial ´pilot´ extension that the small group undertook afterwards to explore the other sites, nature, wildlife, scenery and gastronomy of the Big Island.

During their stay on Hawaii the Kamukona lava ocean entry that started in July 2016 was still ongoing so that they had the chance to observe this volcanic acitivity from land, on the sea and in the air. They also watched on a different occasions the lava lake inside Halema´uma´u crater inside Kilauea´s summit caldera, which was at such a high level that the lava spattering could be seen from ca 2 km distance. Unfortunately there were no on-land lava break outs that they could get to as was the case for the March 2017 Kilauea Volcano Specials. (Photo: Ingrid Smet)

A selection of photos taken during our Expedition to Erta Ale and Dallol in early February 2017 by participant Stefan Tommasini - Fotografie mit Seele (website). This Danakil expedition was particulary unique: on one hand a new eruptions started at a fissure on Erta Ale´s flank which let to the partial collapse of the active craters in the summit caldera; on the other hand it was pouring with rain when our group was at Dallol, which is known to be the hottest and driest place on earth... The rain however intensified the colours and activity at Dallol´s hydrothermal deposits, and the flank eruption created a vast lava field with multiple lava lakes and pahoehoe flows. (You can find a short overview of the 2017 flank eruption and Erta Ale volcanic activity update at the end of June 2017 through this link) (c)

$A selection of photographs taken by Ingrid Smet during our June 2017 Nyiragongo lava lake and mountain gorillas expedition in the DR Congo which included a 3 days / nights stay on Nyiragongo volcano. On 6 June the group completed their hike to the summit in dry weather (the people coming up in the next two days were not so lucky) but had to wait a few hours for a first glance onto the red hot lava lake until the clouds around the stratovolcano´s summit and the thick volcanic gasses inside the caldera had temporarily lifted. The next 2 days (7 and 8 June) visibility into the caldera was usually best in the mornings and at intervals during the night, with more clear circumstances in the early morning and right through to dawn and sunrise on the 8th of June. The world´s largest lava lake (about 220 m across) is situated some 400 m below the rim of Nyiragongo´s summit caldera (a diameter of 1.2 km). When visible, the surface of the active lava lake was continuously in motion as exploding gas bubbles create small degassing fountains that recycle the cold black crust back into the red hot liquid lava. Strong degassing also occurred from the edges of the lava lake, the 2016 hornito and along the southern fracture zone. (Photo: Ingrid Smet)$

After a relatively rainy winter 2016/17, spring on the Greek islands was fantastic! Santorini, one of the most famous islands of the Cyclades, was no exception and offered a paradise for photographers: flowers and green everywhere, with the blue and white of the traditional houses and chapels. The following photos were taken during our Santorini photo tour in April 2017.

Paul Reichert who took part in one of our latest Volcano Specials in January 2017 was lucky to witness one of Erta Ale volcano's most spectacular and intense eruptive phases in decades.
A surge of magma from depth (probably a small rifting episode) caused the lava lake in the southern pit crater of the caldera to overflow, build up a broad shield, before it collapsed, following the draining of the lake through a system of flank fissures 2-4 km downhill from 21 Jan - a mere day after Paul and his group had left.
The following is a selection of pictures of Paul, in approximate chronological order and annotated using the valuable field reports by Richard and our geologist expedition leader Enku who, along with Paul, were lucky enough to see this once-in-a-lifetime event. A big thank you goes to all of the three for sharing their information and images!

On 11 July 2015, a large dome collapse triggered the second largest block and ash pyroclastic flow of the 21st century (surpassed by Merapi in 2010 only), filling and devastating the Montitlán river valley on Colima's south side to a length of about 10 km.
We visited the deposit approx. 16 months later, in Nov 2016 (compare these to photos taken few days after it was deposited). This fresh, the deposit is a fantastic geologic showcase. It provides extremely interesting insights into the dynamics of this kind of pyroclastic density currents and its origin: (Photo: Tom Pfeiffer)

The first of our Danakil expeditions of the 2016-2017 winter season turned out to be an unexpected success - not only because of the flawless logistics and organisation or the friendliness with which local Ethiopians welcome international travelers, but also thanks to the very high activity at Erta Ale and Dallol!
At Erta Ale, the lava lake has been overflowing multiple times a day, sometimes even continuously, constructing a large new area of fresh pahoehoe lava flows on the caldera floor. Our main guide and organiser, Ethiopian geologist Enku, has been regularly visiting this location but never saw it this active and impressive in his 20 years experience.
And also Dallol seems to have stepped up its game: after the slow drying out and shrinking of the hydrothermal activity at this unique location between 2010 and 2015, last year´s rains had transformed it back to is former colourful and fascinating self - and this active area is still growing even in the past few weeks.
Below we gladly share with you a number of images that our participants Hans en Jooske kindly send us days after returning home from their Danakil volcano adventure. (Photo: Hans and Jooske)

It seems that this phenomenal hydrothermal system is increasingly becoming drier (more shades of yellow-orange-brown and less green colours) in comparison to the photographs taken in December 2010 following a particularly rainy period. What could be causing this gradual ´´dehydration´´ of the Dallol hot springs?

Despite the fact there are currently 3 companies which will be extracting groundwater for the mining of potash from the local salts (used as fertiliser), neither one of them has actually started the production phase of their mining activities. So it is unlikely that they are the (main) reason for the slowly drying out of the Dallol hydrothermal field. A conversation with the chief of the local Afar village of Hamadela, discussing the influence of growing tourist numbers on his people and their ways of living, brought to light the area´s staggering drought problem. Whereas 18 months is the longest time span within his life (ca 45 years) over which there was no rain falling in the Dallol area, there has now been no rain for over 50 months... The fact that the only influx of water over the past 4 years has been rain run-off from the surrounding plateaus into the Dallol depression, instead of locally falling rain, therefore seems to be a more likely cause. After all, the colourful Dallol hotsprings have only been regularly visited and photographed over the past decade, so not a lot is known about the hydrothermal system´s long term life cycles and changes. Careful monitoring will hopefully result in a better understanding of this hydrothermal system so that it can be preserved as well as possible for future generations. (Photo: jimkeir)

With a small group we climbed Raung during 14-15 August 2015. The hike involves approx. 20 km trekking and almost 2000 m climbing along a mostly overgrown path as only few people visit this spectacular volcano, even though it is one of Indonesia's most active ones.
We might have witnessed the end of the large 2015 summit eruption, which during June-early August produced large lava flows, lava fountains and significant ash plumes. (Photo: Tom Pfeiffer)

"Vanuatu Mai 2013...

wieder eine Reise mit Volcano Discovery - allein das spricht schon für sich! Es war ein phantastisches Abtauchen in eine andere Welt. Die Herzlichkeit, Hilfsbereitschaft und Freundlichkeit der Menschen auf Tanna und Ambrym war überwältigend. Mich hat es sehr bewegt, mit welcher Liebe sie uns bewirtet und in ihre Gemeinschaft aufgenommen haben. Die Wetterverhältnisse dieses Frühjahr waren wechselhaft - starke Regenfälle wechselten mit tropischer Feuchtigkeit und strahlend blauem Himmel - ideale Bedingungen die unzähligen Fotomotive in verschiedenem Licht darzustellen. Das Temperament und die Aktivität der besichtigten Vulkane ließ unser Herz höher schlagen. Trotz der großen Teilnehmerzahl der Gruppe hat Yashmin als kompetenter Reiseleiter und Ansprechpartner in allen Fragen uns alle sicher durch Vanuatu geführt.
Vielen Dank an das Team und für die gute Vorbereitung."

Vanuatu-Reise Mai 2013: Expeditionsfotos von Dietmar Berendes (84 Bilder)

The photos were taken during 25-28 Nov 2012 when we visited the remote Komba island consisting of Batu Tara volcano during our recent volcano expedition to Indonesia. The volcano has been in continuous strombolian eruption, at fluctuating levels, since 2006. Very favorable weather and sea conditions allowed us to land several times on the narrow beach a few 100 m south of the eastern collapse scar of the volcano, the only place on shore from where the vent and its eruptions are visible. During our stay, activity varied from day to day, and consisted in frequent ash venting, mild to powerful strombolian eruptions accompanied by loud detonations and ejecting bombs to several hundred meters height above the vent, located at about 500 m elevation inside the deep collapse scar.
