Japan Earthquake Increases Flood Risk In Fukushima


During the 2011 Tohoku Earthquake in Japan, the ground level sank along the coast near Onahama Port,  Fukushima Prefecture. This has caused recent average tide levels to rise by about 40cm.

A tide level recording from Onahama Port shows the tide level fluctuations at the time of the quake and the subsquent increase in tide levels.

The CDF collaboration sent to the preprint arxiv a new paper a few days ago. In it, they report on a measurement of the mass difference of top and anti-top quarks. The result would not be worth discussing in detail, if it did not show a 2-sigma discrepancy which might be the first hint of a CPT violation. So let me discuss it here.
