    There are different kinds of Earthquake Detectors. For example, one is called "Quake Alarm™". A link to that product is here:

    http://www.quakealarm.com/

    It:

    -Provides early warning by detecting an earthquake's sound wave before the earthquake's destructive shear wave strikes your area.

    -Fully adjustable sensitivity setting.

    -Automatically resets and shuts off alarm when earthquake stops.

    -Mounts easily to wall. No screws, nails or tools required.

    -Operates off a 9-volt battery

    -Loud distinctive alarm to wake you up.

    -Monitors aftershocks.

    -Offers peace of mind and keeps you informed.

    -Can detect earthquakes that occur many miles away.

    -Saves valuable seconds by removing the normal guesswork involved in earthquake detection.

    -Patented reverse pendulum detection system.

    So that's an example of a Earthquake Detector. I don't know the problems with it.

    Here's the answer to your question:

    "Which areas of the World are prone to Earthquakes?"

    The answer to this question is not as straightforward as it may seem. In order to most accurately answer it, we will rephrase the question four different ways:

    1) For which country do we locate the most earthquakes? Japan. The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes. Not the Japan Tsunami/Earthquake. How they RECORD Earthquakes.

    2) Which country actually has the most earthquakes? Indonesia is in a very active seismic zone, also, but by virtue of its larger size than Japan, it has more total earthquakes.

    3) Which country has the most earthquakes per unit area? This would probably be Tonga, Fiji, or Indonesia since they are all in extremely active seismic areas along subduction zones. The sparse seismic instrumentation in those areas doesn't allow us to actually record all the smaller earthquakes.

    4) Which country has the most catastrophic earthquakes, or which has had the most damage and fatalities? Both China and Iran are in seismically active areas, have very long historical records, and have had many catastrohic earthquakes. Turkey is also worth mentioning in this category.

    Your next question "Why". I don't know for myself.

    I hope this helped you!!

    IF the Philippines did have $29.4 million to enhance (improve what?) AND having such improve will rather be waiting to foretell an earthquake, what is going to you do with the strategies? enable us to take the Mayon volcano (non) eruption as a working occasion. without puffed up contraptions, Phivolcs issued one alert after yet another looking forward to a substantial eruption. anybody assumed this became staggering given the lava bypass which would be seen with the bare eye. This lasted for days. how briskly became the reaction time of the government to call for an evacuation and the obedience of the human beings around the edge of the volcano? If we could are looking forward to an earthquake, what type of mobilization can we do and could the human beings stick to a mobilization order that would no longer be seen (as meant to a volcano with lava) Will that no longer basically create chaos and could do extra harm than good? merely like Ondoy and Pepeng, the place could you have further the inhabitants had you typical it could have been that way? Retrospect. the government now is familiar with that MM will bypass underwater and so does the inhabitants who've been affected, what are they doing to keep away from this from happening lower back? (pondering the Philippines is vendors to typhoons) Have the human beings relocated to larger floor or are they nonetheless residing interior an identical flood vendors aspects? Is the government doing something to scrub the canals, rivers, and drainage structures to keep away from this from happening lower back? no longer!
