After the first warning has been issued, the JMA will start to examine all the sources in detail and will estimate again the tsunami heights. Japan is located on the “Pacific Ring of Fire” where seismic and volcanic activity is high. If you take shelter in a temporary place, try to get further away from water before the next wave arrives because it can be bigger and stronger. “Authorities, who earlier relied on low-tech ways to spread alerts, will now be able to send instant … The location of the epicentre of this earthquake was at 3.2N and 95.82E at a depth of 30 km below mean sea level.
