Alerte magmatique - Magmatic alert
FUJI-YAMA
La pression du magma s'élève !
Des géophysiciens japonais affirment que, suite au séisme du 11 mars 2011, la chambre magmatique sous le mont Fuji a vu sa pression grimper sous l'effet de contraintes tectoniques nouvelles. De quoi déclencher une éruption volcanique... Mais, pour autant, aucun signe ne se manifeste actuellement.
Le 11 mars 2011, un séisme de magnitude 9 au large du Japon provoquait quelques heures plus tard un terrible tsunami. D’après un groupe de chercheurs du National Research Institute for Earth Science and Disaster Prevention japonais, les mouvements tectoniques induits dans la région du mont Fuji ont fait monter la pression s’exerçant sur la chambre magmatique de ce stratovolcan emblématique du pays du Soleil levant.
Situé au centre de l’île de Honshu près de la côte orientale, il est la plus haute montagne du Japon avec ses 3.776 m. Manifestation du volcanisme de subduction, le mont Fuji est parsemé de cônes de cendres caractéristiques d'éruptions de type stromboliennes.
D’après les géophysiciens, la pression sur les parois de la chambre magmatique alimentant les éruptions du mont Fuji serait désormais de 1,6 mégapascal soit 15,8 kilogrammes par centimètre carré. Cette pression est énorme : c’est 16 fois la valeur seuil reconnue comme permettant à une éruption volcanique de se produire.
Certes, le mont Fuji ne montre aucun signe d’une reprise de son activité d’émissions de lave et, de plus, la quantité de magma présent dans la chambre ne semble bien pas suffisante pour que se déclenche un tel événement. Toutefois, sa dernière éruption, en décembre 1707, 49 jours après un séisme majeur, semble bel et bien avoir résulté d’une augmentation similaire des contraintes tectoniques sur sa chambre magmatique.
La prudence s’impose donc. Le mont Fuji, bardé de dizaines de sismomètres et de capteurs GPS, est surveillé 24 h sur 24. En 2004, le gouvernement japonais a estimé qu'une éruption de ce volcan affecterait plus de 700.000 personnes, y compris dans la région de Tokyo.

FUJI-YAMA
The pressure of magma rises !
Japanese geophysicists say, after the earthquake of 11 March 2011, the magma chamber beneath Mount Fuji seen the pressure rise due to tectonic new. What trigger a volcanic eruption ... But, so far, no sign appears now.
March 11, 2011, a magnitude 9 earthquake off Japan caused a few hours later, a terrible tsunami. According to a group of researchers at the National Research Institute for Earth Science and Disaster Prevention of Japan, tectonic movements induced in the region of Mount Fuji have raised the pressure on the magma chamber of the country's iconic stratovolcano of the Rising Sun .
Located in the center of the island of Honshu near the east coast, it is the highest mountain in Japan with its 3776 m. Manifestation of subduction volcanism, Mount Fuji is dotted with cinder cones characteristic of Strombolian type eruptions.
According to geophysicists, the pressure on the walls of the magma chamber feeding the eruptions of Mount Fuji is now 1.6 megapascals or 15.8 kilograms per square centimeter. The pressure is enormous: it is 16 times the threshold value known as a volcanic eruption to occur.
Of course, Mount Fuji shows no sign of recovery of its activity and emission of lava, in addition, the amount of magma in the chamber does not seem enough for such an event is triggered. However, its last eruption in December 1707, 49 days after a major earthquake, does seem to have resulted in a similar increase in tectonic stress on its magma chamber.
Caution is therefore required. Mount Fuji, bristling with dozens of seismometers and GPS sensors is monitored 24 hours 24. In 2004, the Japanese government estimated that this volcanic eruption affect more than 700,000 people, including the Tokyo area.

Magik, c'est une image fantastique que vous avez créé. il fait très chaud et semble être sur le feu comme un volcan. merci pour l'information à propos de Mt. Fuji, c'était très intéressant

excellent image render, love the design of what i suppose is a research center directly above the magma! thanx for the history of mt. fugi, i'll steer clear of that area!:)*5
