Earthquake in Kyusyu, Japan still continues. No one knows when it completely stops yet. I care the people there and I also afraid the nuclear reactors they are still running there. (Japan only has two running reactors now, both are in Kyusyu area where the earthquake continues. The number of earthquakes more than scale 1 is 770 times so far.) There are several petition to stop the reactors now. I also joined. But, technically stopping them are not enough.
