Though, the development of the general science, management science, we see the world in unrest, economical crisis or in the fire, like Marseille in France. I mention you some points for a better apprehending of the situations. When we study a phenomenon in the science like physics, we try to generalize the results. It is for avoiding repeated works on the same subject. We use analogy, inductive reasoning, and more complicated theoretical methods. The second thing is simplicity; we simplify to see the subject more clearly. There is several way of simplification. We can study only one part of an object having a several symmetrical part and eliminate similar parts when possible. Ease of use; we have to offer easy methods more people can try it. Producing more cheap to make it available to more people.
When we see the natural map of Europe, it is easy to see the earthquake of a point near Duisburg, in Germany, is on the same fault passing through Marseille. Eastern part pushes against western part and we have an earthquake in Germany and a fire in Marseille and a little bit further in the Nord of Marseille, in Vosges, a less strong earthquake.
When I was travelling along a road east of Tehran, I saw a small mountain with layers of sediments perpendicular to horizontal line. The layers are deposed horizontally over each other and are parallel to horizontal line. How they become vertical?
We have two mechanisms in the faults, or two parts of the fault are separating from each other, either they are pushing toward each other. I do not take other possibilities. When they are separating from each other, more space is available for the mountains leaning on one of these parts. If this separation is very slow, we can see a geological structure is moving slowly as well without destruction. This fault is prone to penetration of magma, and friction heat as well. We have in these region weak earthquakes from time to time. It is clear there is a fault under this small mountain.
The solution could be constructing a road with building a bridge made of steel cords and hanging out weights at the end of this steel ropes. Movement of up and down by these weights might show the extent of activity of this fault.
It is the same for Marseille, there is a fault, underground fault, and we see fire along it. We have to dig wells along this fault and release, the heat. Now that fire has devastated the region, the geological structures are more visible. Of course, new technologies allow us to determine these underground faults as well. Anyhow, regions prone to fire, sometimes, could be recognized by simple and cheap methods. Economically, we have to develop easy to use and cheap products for the survival of the society. It is clear a wheel of an ancient carriage is not the same as a wheel of a modern car.

Building a rather big model of an alarming device when earthquakes happen is very easy. It is enough to hang up a pendulum from a up side down metallic L, shape. You can make it by welding two iron rods and welding a metallic hook at the end. You place the end of the pendulum inside a fixed metallic tube. Then, you solder two wires to tube and pendulum and two other sides to a siren or alarm bell electric part. You can build several devices with different tube sizes, each for Richter intensity. Of course, for 5 Richter intensity, pendulums of 3,4,5 richter intensity give alarm simultaneously.
The function is as follows: the compressional waves P (primary) is traveling 1.7 times secondary waves and arrive sooner to a point near the earthquake center. As the P waves are less destructive than S waves and arrive sooner they are good alarms, but this happens, maybe, 30 seconds before arrival of S waves. Almost, this is not enough time to move and specially for apartments. Anyhow, two important results are:
1- If you receive several alarms in a short period of time, it could be a sign of a stronger earthquake. In volcanoes, there is an exhaust way, By the earthquakes, if the vent is close, will be open and earthquakes become stronger to open it, and volcanoes erupts. But, sometimes, the magma does not come up enough and only produces energy. And earthquakes could be frequent and it could be a sign of a stronger earthquake. I mentioned it in my article about one of Peking city seismological stations very quite activity for about two years in the Sichuan earthquake article. This activity ended by Sichuan earthquake.
2- You can connect the electric part of this alarm to very expensive or vital devices, if you can predict the next one could be strong to cut off the electricity or closing automatic valves.
