Since massive earthquakes hit Japan in March, it has been reported that unusual things are going on. In some well-know hot-spring areas which are far from the epicenter of the 3/11 main shock, hot-spring water suddenly ran dry immediately after the 3/11 earthquake occurred. On the other hand, in some areas, more hot-spring water is coming out. Other than this, the quality and temperature of hot-spring water have changed in some areas. 
It's been reported that a large amount of hot-spring water started coming out of a big vent hole in a residential area in Iwaki, Fukushima after a massive aftershock hit the area in April, and there is still no sign that the water will stop coming (Fukushima is the third largest prefecture in area. The largest one is Hokkaido and the second one is Iwate). The vent hole was used for colliery ventilation before, but now it isn't used. The water temperature is over 50 degrees. People in the area have been suffering from exposure to the sulfur odor. Since there is no way to stop the hot-spring water, the water is reluctantly being run into a creek to prevent houses from being swamped by the water. Despite that, some of the water is running under some houses. Many trees around the creek are dying.I've heard that we can strike hot springs anywhere in Japan, so there would be no surprise if water were to come out near my house someday. The earthquake was so massive that we can find something unusual anywhere throughout Japan.
