the mechanisms of 82 out of the 99 earthquakes in total located between 17 and 26 km
depth and thus shows nearly the same results as described earlier for that interval, that the
tension axis is chiefly horizontal

Short summary
Despite the documented severity and lasting geomorphic imprint of the 1362 and 1727 jökulhlaups from Öræfajökull, there is scant information about the routing and extent of these floods. Using field observations, aerial photographs, and modern-day analogues

In recent years, Arctic nations have consolidated their cooperation in the fields of meteorology and Arctic hydrology, to increase monitoring and research on Arctic warming and into various components of the Arctic Hydrological Cycle.
The Arctic Ocean covers only 1% of the total area of the world´s oceans, but receives 10

Tomorrow morning, Friday 20 March 2015, an almost total solar eclipse will be seen from Iceland, such as has not been seen for 61 years. And it so happens, that this time, it will occur on equinox.
