Japan's Meteorological Agency (JMA) has issued a tsunami warning for the entire Pacific coast, covering regions in both western and eastern Japan. The warning was prompted by detection of unusual seismic activity across this vast area.
According to the JMA, tsunami waves could strike the coast with varying heights depending on the region. Residents living along the Pacific coastline are urged to evacuate immediately to higher ground or move further inland, staying away from the coast until further notice.
Japanese authorities are coordinating with the Self-Defense Forces and local governments to implement response measures. Public address systems and emergency alerts have been activated on a large scale to warn the public. The tsunami warning does not rule out the possibility of larger waves if additional aftershocks occur.
Detailed information about the earthquake's epicenter and magnitude is being updated and released by the JMA in subsequent advisories. Officials advise residents not to return to coastal areas until the warning is officially lifted.
