When an earthquake occurs in a sea or in the ocean , after a short time
there may be a large wave of a certain height , in relation to the
magnitude of the earthquake , the distance to the place where you are…
If you know the altitude of the place where you are, you can decide what to do…
The application “Need_help” uses BING MAP facilities and determines the
altitude of the place where you are.
Otherwise, GOOD LUCK!!!
