US Navy Physicist warns of possibly 'several decades of crushing cold temperatures and global famine'

"Since the current transition now exceeds 568 spotless days, it is becoming clear that sun has undergone a state change. It is now evident that the Grand Maxima state that has persisted during most of the 20th century has come to an abrupt end. "(The sun) might (1) revert to the old solar cycles or (2) the sun might go even quieter into a "Dalton Minimum" or a Grand Minima such as the "Maunder Minimum".

Deux expéditions en 2003 (il aura fallut deux expéditions pour finalement comprendre) ont conclu fondements à l’appui, que c’est une formation géologique d’origine terrestre. Le principe en résumé : en profondeur, un sole composé d’une alternance de couches de calcaire — fragile — et de couches de quartz ou granite — solide. Une bulle de magma a poussé par dessous formant un relief (classique, rien de spéciale jusque là). La bulle de magma était accompagné d’eau très chaude, qui a dissous le calcaire du renflement, fragilisant sa structure par des zones vides entre les couche de granite.

Finalement, fragilisé, l’ensemble s’est effondré, et les relief circulaire restant sont les reliquats des couches de quartz qui n’ont pas été dissous ni érodés.

By Daily Mail Reporter Updated: 16:29 GMT, 14 January 2011 The sun over Greenland has risen two days early, baffling scientists and sparking fears that Arctic icecaps are melting faster than previously thought.

Experts say the sun should have risen over the Arctic nation's most westerly town, Ilulissat, yesterday, ending a month-and-a-half of winter darkness. But for the first time in history light began creeping over the horizon at around 1pm on Tuesday - 48 hours ahead of the usual date of 13 January. The mysterious sunrise has confused scientists, although it is believed the most likely explanation is that it is down to the lower height of melting icecaps allowing the sun's light to penetrate through earlier. Climate change? Thomas Posch, of the Institute for Astronomy of the University of Vienna, said that a local change of the horizon was 'by far the most obvious explanation'. He said as the ice sinks, so to does the horizon, creating the illusion that the sun has risen early. Help. Tremblement de terre de magnitude 4,3-près du mont St. Helens est le plus grand en 30 ans.

Helens from the north side at Johnston Ridge after sunset. Fault line, won't you be my Valentine? The second largest earthquake since Mount St. Helens erupted -- a magnitude 4.3 shaker -- rocked a fault line six miles north of the volcano Monday morning. People felt it as far away as Astoria, Lake Oswego, Hood River and even Bremerton, Wash., near Seattle. Avez-crapauds prévoir le tremblement de terre?

According to recent estimates, the earthquake that hit China on Monday could leave 10,000 people dead.

Web users are saying that the catastrophe could have been avoided, if only they had listened to the toads. Two days before the quake thousands of toads suddenly decided to move across a bridge in Taizhou, a town in the Jiangsu province (see photos). Chinese web users are wondering why the local authorities didn't relate the event to the imminence of an earthquake, and why scientists didn't take notice of the bizarre disappearance of a lake in Enshi, in the Hubei province, on April 26 (see photos). A seismologist tells us that the Chinese have long relied on the behaviour of animals to predict earthquakes. WDSS-II: KTLX WSR-88D. Tremblements de terre récents dans Hawai `i - Index des cartes.

They were first photographed in 1968 in Japan. USGS admits their existence. Records of earthquakes that were accompanied by sky lights can be found in 373 BC in ancient Greek writings, that "immense columns of flame" foretold the earthquake that destroyed the cities of Helike and Bura. However, even in the early 20th century they were still considered a myth, until photographs of actual lights were taken in Japan in the 1960s. William Leigh Pierce, a traveler on the Mississippi, observed, "On the 30th of November, 1811 about one half hour before sun-rise, two vast electrical columns shot up from the eastern horizon, until their heads reached the zenith" -- from Feldman book >> Photograph of earthquake lights, -- more on their possible causes.
