※Earthquake Early Warning is notified with warning tones and
voice alerts ("地震です" (Earthquake incoming)).
◎ When an earthquake with an estimated maximum intensity of
low-5 or greater occurs, an Earthquake Early Warning is sent
to phones in areas where strong tremors (intensity of 4 or
greater) are expected.
◎ Immediately after an earthquake occurs, tremors near the
epicenter (P-wave, preliminary tremors) are picked up and the
location, scale, and expected tremor intensity are
automatically calculated, and an alert is issued as quickly as
possible, from a few seconds to tens of seconds before strong
tremors (S-wave, principal shock) start.
◎ In locations near the epicenter of an earthquake, there may not
be enough time to receive an Earthquake Early Warning before
strong tremors start.
◎ Tsunami Warning is notifications sent to applicable coastal
areas based on Major Tsunami Warning and Tsunami Warning
issued by the Japan Meteorological Agency.
◎ Disaster and Evacuation Information is notifications of national
and local evacuation advisories, evacuation orders, and other
types of information related to citizen safety.
◎ These services are available in Japan only. They cannot be
used in other countries.
◎ Emergency Rapid Mail is provided free of information charge
and communication charge.
◎ KDDI is not liable in any way for losses incurred due to
communication breakdown or system breakdown resulting in
failure or delay in communications or information due to any
causes that are beyond the responsibility of KDDI.
