Tanzania’s Ol Doinyo Lengai volcano is unique in the world : its liquid black lava turns snow white when it cools down. Our distant ancestors left some footprints which were petrified by the volcano 20,000 years ago... Mathieu Kervyn, a volcanologist at the University of Brussels, is one of the rare specialists of this particular volcano. It has not been studied much due to its difficult accessibility.

In Japan, the sense of belonging to the land is very strong, especially when one can enjoy the benefits of geothermal energy : hot baths and volcanic cooking.

In Hawaii, the Kilauea volcano has been erupting continuously since 1983. Its glowing streams flow into the Pacific in a magical commotion of water and fire, transforming the island into an everlasting cycle of creation and destruction. If the lava of the volcano creates new lands on the ocean, it also destroys entire villages such as Kalapana where a community still lives in harmony with their fiery giant. Women and men rebuilt their homes on black lava, where their old lands were situated. Every week, they come together and celebrate the carnal bond that ties them to the Hawaiian volcanic land. For any volcano enthusiast, the grail is to get closer to the lava and to take a sample, as did Haroun Tazief, the legendary volcanologist…Arnaud Guerin’s dream has comes true.

In Indonesia, Kawah Ijen reveals its infernal insides. Miners extracting sulfur work in extreme conditions, and take turns daily in the inferno of the crater. One of the workers, Sarno, has been working there for twenty-eight years. Under such severe conditions, he would extract sulfur with a mining bar and carry 75 kilos of it on his back. Sum Arti, a volcanologist, monitors the level of danger linked to gases and protects miners from the risk of gas bubbles that can potentially be lethal.

Despite its peaceful demeanour, the volcanoes in Auvergne have known a tumultuous past. Large reserves of magma have been discovered recently in the underground depths and a new eruption cannot be ruled out entirely. The Pavin Lake is said to be cursed ...

In Ecuador, the Cotopaxi volcano rises to almost 5 900 meters in altitude. The glaciers that cover its crest are constantly being monitored : in the event of an eruption, their melting could cause devastating mudslides. Scientific expeditions conducted at such high altitude are a real challenge, especially for Arnaud Guérin, who suffers from acute mountain sickness. At the foot of the volcano, the Chagras move their cattle on horseback. If an eruption occurs, they can quickly evacuate their endangered herds. Santiago Benitez is a shaman who keeps the temazcal tradition alive. It is a very ancient spiritual practice that involves heating volcanic rocks.

Each of its tremors is constantly monitored : the Vesuvius is one of the world’s most famous and dangerous volcanoes. At its feet lies the city of Naples, the third largest city in Italy, and its 970,000 inhabitants. Its eruption, in 79 AD made history and it literally destroyed the cities of Pompeii and Herculaneum. But for centuries, Neapolitans have accepted this risk and benefited from the volcano's resources.

Before then, the Aeolian islands were poor and inhospitable. Only a few inhabitants lived there, like Pasquale, a modest olive grower. Only half a century ago, the island still harboured a prison ...

For nearly a thousand years, islanders have learned to master volcanic forces. A strong bond ties them to their land which offers them many gifts : beautiful obsidian stones and exceptional hot springs. Local sources of geothermal energy are another one of these volcanic treasures from "the land of the long white cloud". Some tribes have integrated this natural energy to their daily lives. This phenomenal source of energy also has more modern applications : it can provide enough electricty for 160,000 homes in New Zealand.

Reunion island brings us on a journey through volcanic time ... The young Piton de la Fournaise figures today among the world’s most active volcanoes ... Its extreme activity is linked to its youth. Aline Peltier, a volcanologist, monitors this volcano closely because of its five annual eruptions. Its neighbour, which sleeps nearby, the venerable Piton des Neiges, show traces of millions of years of volcanic activity on its slopes. Its study helps scientists anticipate the future transformations of the Piton de la Fournaise. Not far from there, an amazing local community lives in near autarky.

In Guatemala, the Fuego volcano is permanently active, threatening tens of thousands inhabitants. Gustavo Chigna, a volcanologist, inspects its slopes to measure the quantities of accumulated volcanic materials. In the village of La Trinidad, located 5 km away from the active crater, lives a small community that understands the risks involved in case of eruption ...

In Japan, the Sakurajima volcano erupts almost daily and threatens the 600,000 inhabitants that live at its feet. On the flanks of the volcano, every morning, children make their way to school with protective helmets. The ash that accumulates in the village forces the inhabitants to perform a daily cleaning. But these ashes are also a source of benefits. Mr. Shirahama, a farmer, cultivates the largest radishes in the world. Meanwhile Japanese scientists monitor the volcanoes 24 hours a day.

In Guatemala, the Santiaguito volcano was born less than 100 years ago. Scientists are fascinated by its youth and intense activity. Volcanologists from allover the world are attracted by the unique opportunity to observe a volcano in the early stage of its life.

For the descendants of the Mayan people, the Santiaguito and many other volcanoes of the region symbolise the creative power of nature.

Iceland is undoubtedly volcano kingdom. It is the most important volcanic island on the planet, its land produce nearly a third of the world's lava. Its lunar territory is the battlefield for the elements : water, ice and fire. Here, the volcanoes impose their laws which men, animals and everyone bows down to. Beyond the risk of fires, a rising source of concern is linked to the glaciers that cover some of these volcanoes. These are monitored daily as their interaction with the volcanic heat, deep down, can generate huge glacial floods that destroy everything on their path.

In Hawaii, Mauna Loa is the largest active volcano on the planet. Its colossal mass could cause unsuspected dangers : its unstable flanks could collapse into the ocean and cause a mega-tsunami. Gérard Fryer, a geophysicist, devoted his entire life to the study of this unknown phenomenon: by entering the water, this enormous mass of rock forms giant waves, 300 meters high. Other tsunamis caused by earthquakes around the Pacific regularly affect the island’s coast. The volcano’s peak is so high that scientists have settled there to study global warming.

New Zealand is the theatre of Earth’s most violent volcanic eruptions. Lake Taupo witnessed a cataclysmic eruption which rejected enough ash to cover an entire country the size of France. White Island, located 40 kilometres off the coast, is a unique place, home to a capricious lake of craters that flows into the sea or evaporates depending on magmatic activity. For the Maori people, these volcanic lakes are sacred as they are home to gods like Ruapehu. When scientists come to study this lake, they abide by their rules and follow the prayers of a Maori guide...

Tungurahua is an explosive volcano in Ecuador. In 2006, the district of Palictahua was destroyed. Since then, its inhabitants have taken action to join forces.
