Volcano

   A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface.

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism.^[1] Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core–mantle boundary, 3,000 km deep in the Earth.

Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. Volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature. Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere or troposphere; however, they also absorb heat radiated up from the Earth, thereby warming the stratosphere. Historically, so-called volcanic winters have caused catastrophic famines

Snow canyons in Japan

Yesterday I read a really interesting article  and it shows us the comparison between the condition of New York and Honsu Island in this snowy time. The condition in New York is sure bad, but compared to Honsu, wow I am shocked. Here are the pictures of snow in Honsu Island in the article and just like the article said it is a real snow and not photoshopped.

Tateyama Kurobe Alpine Route, linking Toyama and Nagano Prefecture, is a world class sightseeing roadway soaring through Mt. Tateyama heights that along with Mt. Fuji and Mt. Hakusan is one of Japan's three most beloved mountains. Snow is so abundant the route closes during winter to re-open in mid-April when snowplows blast through creating 'Yuki-no Otani' (snow canyon), an extraordinary snow corridor up to 20-meters-high which is a spectacular sight for travelers until the end of May. The 3,000 meters high mountain range can be traveled via bus with cable cars and ropeways offering more options for visitors to enjoy grandiose views along with splendid summer alpine flora and an artist's palette of multi-colored foliage in the fall. Witnessing the drainage of Kurobe Dam, Japan's most lofty at 186 meters high, is a must do excursion between June 26 and October 15.
