What combination of factors was responsible for the vaiont dam disaster in italy in october 1963?

Causes of the landslide:   rainfall, dam level changes, earthquakes ( as triggers of the landslide), the choice of the site ( the canyon was steep sided), the river had undercut its banks, and the limestone and clay-stone rocks that formed the walls were inter-bedded.

it was the "4. potsdam" conference that demanded the unconditional surrender of japan, since it was clear that the japanese would continue to find until the very last man otherwise.
