While it has been almost four weeks since Basse Terre, at the foot of the Soufrière volcano in Guadeloupe, was evacuated, scientists are opposed to Haroun Tazieff’s optimistic thesis. Asked about the controversy, the famous vulcanologist recalls his scientific titles and repeats that a catastrophic eruption is not currently planned. He regrets the haste of government scientists who evacuated the site without thorough studies.
Maurice KRAFFT, in an assembly room of FR3 Franche Comté, compares the volcanologist to a doctor and describes the signs that allow to detect a volcanic eruption. He recalls that volcanoes kill and that in five years "five colleagues have been torn apart by volcanic eruptions".
Invited to the Screen Folders, volcanologist Haroun Tazieff talks about the world’s largest volcano, the Mauna Loa on the island of Hawaii, which he says is colossal but one of the least dangerous in the world. He explains that a smaller, more explosive volcano can be infinitely more dangerous. "The danger does not come from the volume, but from the quantity and pressure of the gases in the magma," he stresses.
The volcanologist Haroun Tazieff, interviewed at the edge of a crack in Mount Etna, where lava flows and vapours escape, describes the phenomena observed.
Report devoted to the exercises of evacuation and awareness of the dangers of Vesuvius in Naples, a first in Italy and even in the world. Plans and microsidewalk of volunteers participating in the general rehearsal of the evacuation simulation. Interview of a first aid attendant. Plateau by Gérard GRIZBEC.
Katia KRAFFT talks about the risks of her job as a volcanologist and about the secrets of eruptions she hopes to discover as she approaches volcanoes. She says: 'I don’t like danger, but by being in somewhat impressive situations one always wants to have more, and especially to go closer to be able to observe (...). For all that is explosive, the Pelee Mountain, Mount St Helens, the Indonesian volcanoes, there are still many things that we did not understand in the course of the eruption."
Haroun TAZIEFF recalls that the phenomena of volcano formation are still hypothetical. He answers the question of the choice of the terms "vulcanologist" or "volcanologist".
On the plateau, Haroun TAZIEFF talks about the situation in the Philippines and Japan after the revival of the Pinatubo and Unzen volcanoes. He believes that if volcanoes were monitored, disasters could be avoided.
French scientists have set up a system to test the interior of the Piton de la Fournaise volcano on Reunion Island to monitor its activity and anticipate its eruptions. They implanted sensors on the flanks of the volcano. Images of a volcanic eruption, work plans of the researchers on site. Interviews with Philippe KOWALSKI, Deputy Director of the Observatoire volcanologique de la Fournaise (registered on 01/07/2014) and with Florent BRENGUIER, physicist.
While Etna still threatens the village of Zaferalla in Sicily, relief forces are trying to stop the flow of lava by sending concrete blocks to the edge of the volcano’s crater. The inhabitants accuse the Italian authorities of not having mobilized in time to protect the place. Images of a helicopter in flight, lava progression, a burning house. Interview with Franco BARBERI, coordinator of civil protection (in Italian). Plateau in situation of Jean-Louis LESCENE, special envoy to Sicily.
A report shot at the La Réunion volcanological observatory, which, since the beginning of July, has been measuring increased activity at the Piton de la Fournaise. Commentary on images of scientists on the sides of the volcano near the monitoring facilities, alternating with an interview with Philippe KOWALSKI, Technical Director of the Observatory.
In the Congo, volcanologists who are checking the Nyiragongo volcano’s eruption fear that the lava flowing into Lake Kivu will explode the enormous quantities of toxic gas buried under the lake, which could rise to the surface. The seismic activity of the volcano remains very strong and volcanologists lack recoil for this type of eruption, very rare, as Jacques DURIEUX explains. Dario TEDESCO, a geologist consultant at the UN, believes that the risks of eruption in the coming months or years are a great danger for the people.
The story of the volcanic activity of the Piton de la Fournaise in La Réunion. After eight weeks of volcanic eruption, a lava lake formed at the bottom of the crater. Plans of the formation of this lava lake.
Speleological visit of the natural volcanic pipelines of the Piton de la Fournaise in La Réunion, which were dug during the last lava flows, early October 2005. Plans of an expedition of cavers and volcanologists.
In the Democratic Republic of Congo, two weeks after the Nyiragongo volcano erupted, more than 300,000 people still need help. Specialists monitoring the volcano’s activity are very concerned. Volcanologists on the spot multiply the observations because the Nyiragongo, located 15 kilometres from Goma, is still very active, as confirmed by the frequent earthquakes that shake the region. Interviews with Jean Christophe KOMOROWSKI, geologist at the Institut physique du globe de Paris, Jacques DURIEUX, volcanologist and Dieudonné KAVOTA, volcanologist at the Goma Observatory. Aerial views of the eruption area, plans of the magma, a group of on-site volcanologists and the CRSN-Goma volcanological observatory.
Report on Java Island in Indonesia, devoted to the activity of the Merapi volcano in Yogyakarta, located about 70 kilometers from the epicenter of the recent earthquake. Seismic and volcanic phenomena are often linked and since this morning the Merapi shows signs of increasing activity. Plans of the volcano and the victims unlocking the rubble of the earthquake alternating with the testimonies of the inhabitants and the interviews of Pauline TEXIER, geographer and Bapa PANUT, observatory of the Merapi volcano. Plateau in position of Philippe ROCHOT, special envoy to Yogyakarta.
Report devoted to the Etna eruption in Sicily. A new mouth opened near the crater and lava flows destroyed the funicular station that usually allows tourists to go to the top of the volcano. Images of the volcano and works to prevent lava flows. Interviews with Giovanni FRAZZETTA, the National Institute of Geophysics and Volcanology and Nello MUSUMECI, President of the Province of Catania. Plateau in Stéphanie PEREZ, sent special in Sicily.
