小行星 彗星撞击 大气科学 高层大气物理学
2023/6/21
Between 2.5 and 4 billion years ago, a time known as the Archean eon, Earth’s weather could often be described as cloudy with a chance of asteroid.
Back then, it was not uncommon for asteroids or com...

New research shows that an iceless Greenland may be in the future. If worldwide greenhouse gas emissions remain on their current trajectory, Greenland may be ice-free by the year 3000. By the end of t...
Sand Liquefaction Phenomena During the Seismic Crisis of May 2012 in Emilia, Northern Italy
and boils composition Emilia Romagna earthquake
2018/6/13
In May 2012, the Emilia region of the Po Valley was struck by a seismic crisis with two major events of magnitude Mw 6.1 and Mw 5.9. The first event induced widespread sand blows formed along buried c...

Static stress transfer from the May 20,2012,M 6.1 Emilia-Romagna (northern Italy) earthquake using a co-seismic slip distribution model
Stress Transfer Slip distribution Italy
2015/8/26
We model the static stress transfer for the May 2012 northern Italy earthquakes, assuming that failure of the crust occurs by shear. This allows the mechanics of the process to be approximated by the ...
