◎ Immediately after an earthquake occurs, quakes (P waves and
initial tremors) near the epicenter are detected and position,
scale, and expected strength are automatically calculated and
notification is sent as soon as possible within a few seconds to
tens of seconds before the strong quakes (S waves and major
tremors) caused by the earthquake start.
◎ Emergency earthquake information may not arrive before strong
tremors in areas near the epicenter.
◎ Disaster evacuation information is a service that distributes
bulletins concerning residents' safety including evacuation
advisories, evacuation orders and other warnings issued by the
national and local governments.
◎ This service is available only in Japan (it cannot be used
overseas).
◎ No information fee or communication charge is required for
receiving emergency early warning mail.
◎ KDDI is not liable for damages suffered by customers resulting
from the service's information, lack or delay in the information
caused by transmission or system breakdowns, or other events
that are outside the responsibility of KDDI.
◎ Refer to the Japan Meteorological Agency web page for details
about distribution of emergency earthquake information.

◎ Emergency early warning mail cannot be received if your cell
phone is turned off or during a call.
◎ You cannot or may not be able to receive emergency early
warning mail when sending an SMS (C-mail) or e-mail, using
browser, or if you are in a place where signal does not reach
even in the service area (e.g. in a tunnel, basement) or in a place
with a poor reception.
◎ In such case, the same warning mail cannot be received later again.
◎ Since emergency early warning mail uses a different delivery
system, the reception time of emergency early warning mail may
not coincide with the same emergency warnings broadcasted
through TV, radio or other media.
◎ Information from someplace other than your current location
may be received.
