Mount Rainier and Tacoma, Washington as seen from the shore along Commencement Bay. Rainier, located in Washington State, has been predicted to have a major eruption in the near future for quite some time now. If you missed seeing this spectacular sight, astronomer and photographer Matt Dieterich has an incredible image that will have you running outside to catch the Perseids the next time they appear. C'est ce dernier phénomène qui a engendré, il y a 5 600 ans, le plus gros lahar connu des géologues. The sheer number of meteors—coupled with the majesty of the Milky Way and the iconic Mount Rainier—makes for an unforgettable photo. Le manque d'air dû à l'altitude associé à la présence dans l'atmosphère de CO2 essouffle rapidement les volcanologues. On pénètre alors dans un monde étrange, plongé dans l'obscurité, celui des grottes de glace : les fumerolles chaudes qui parsèment le sol ont fait fondre la glace à certains endroits et y ont sculpté un réseau de cavernes long d'environ deux kilomètres, le plus long connu actuellement. Chine : à la découverte des plantes qui fixent les sols, Lorsque la Terre tremble au rythme des saisons. She earned her MA in Renaissance Studies from University College London and now lives in Rome, Italy. 5600 years ago a small eruption on Rainier caused lahars to deposit mud from the mountain all across the Puget Sound region.

The area lies downstream from Mount Rainier, which carries the questionable honor of being one of the most dangerous volcanoes in existence. Weak, hydrothermally altered rocks remain at high elevation on the volcano's west flank, and some of this material could be dislodged by earthquakes during an eruptive period.
