This information is put into the Earthquake Phenomena Observation System EPOS at the headquarters in Tokyo When an earthquake occurs JMA immediately issues to the public, information on its hypocenter, magnitude and observed seismic intensity. Impact Japan was largely prepared for the earthquake and many buildings remained standing afterwards, but it was not prepared for the subsequent Tsunami. Many of them streamed out of buildings in the business district, gathering in open areas. We’ll assume you’re ok with this, but you can opt-out if you wish.
