You may have worldwide earthquake alerts sent to your computer, pager,mobile, cell phone by subscribing to the:

Earthquake Notification Service (click here)

NOTE: An earthquake with a magnitude above 6.5 is generally considered capable of generating a TSUNAMI

and should trigger immediate plans for an appropriate response in that area.

Tsunami Safety Rules (#12) and other excellent information about tsunamis can be found...HERE



(1) Let's start with an effort to bring an emergency communications systems to those living near the sea. Why? According to Don Hinrichen of PeopleandPlanet, half of the world lives within 200km of the of oceans. Tsunamis are not the only concern. In many parts of the world the major concern is large storms such as typhoons and hurricanes that often ravage coastal communities. Warning about storms may be far more important!

(2) Developing and deploying a tsunami warning system is relatively easy and straightforward. The Japanese government has indicated it wants to take the lead in building such a system in the Indian Ocean area. Communicating alerts and advisories to those affected in a timely fashion is the real challenge!

(3) The author proposes an emergency communications system using existing satellite radio, the Internet, mobile/cellular telephones and pagers, and broadcast media. Those outside the range of TV and radio broadcast stations, the Internet, and mobile phone coverage could receive emergency communication via satellites such as Worldspace and XM. As an immediate first step, alerts of magnitude 6.5 or greater earthquakes could be sent to mobile/cellular phones, pagers, and satellite radio (using an existing 16K service channel on the satellite) users now. NO NEED TO WAIT FOR SOME NEW SYSTEM TO BE DEVELOPED AND DEPLOYED!. The originators of existing warnings (USGS and others) need to find ways to reduce the time required to create and disseminate time critical information (with potential tsunamis, for example where every minute of delay means greater loss of life)

(4) The USA has been developing and perfecting an emergency communications system for more than 45 years (E.A.S. and S.A.M.E.). The author of this site proposes that a similar system be adopted worldwide because the hardware for the consumer is cheap (less than $30 US retail for a hand held or base station emergency/weather receiver) and the system works well. There is no need for the rest of the world to start from scratch developing a completely new system!

(5) The SAME and EAS systems from the USA could be used for both broadcast and satellite activated emergency alerts.

(6) The author proposes that as a simple first step, AM/FM/SHORTWAVE and TV and satellite receivers be equipped with a simple WAT (Warning Alert Tone-1050Hz and/or EAS attention signal w/ dual tones of 853 and 960 Hz ) decoder with MUTE function allowing listeners to receive warnings regarding a local, national or regional emergency. This would add less than $5 to the cost of the receiver. Later, integration of the SAME and/or EAS technology could also be done. The SAME and EAS system allows digital transmission of specific types of warnings, as well as means to activate an alarm, aimed at specific areas. On the provider side, all the necessary equipment for transmitting these warnings is already available(Click here for list of consumer and commercial grade equipment). The cost of this equipment would decrease dramatically when the market expands beyond the USA.

(7)Amateur Radio could and should play a significant role not only in providing disaster communications, but also in relaying vital emergency warnings via voice, digital modes and Amateur satellites.
