The correct and practical earthquake prediction theory can be achieved by
the way of Trial and Error.
For example, the low-frequency radio wave (electromagnetic wave) anomaly before some strong earthquakes are reported in both China and United States. Some of the precursory observation stations in China have recorded very strong electromagnetic anomaly signals before several big earthquakes. In the United States, just during the several days before and after the 1989 San Fransisco Earthquake, strong low frquency radio wave signals were also recorded. Obviously, a hypothesis on the prediction theory can be purposed based on all these reports; then through more and more observations, the hypothesis can be improved until it is good enough to be a practical prediction theory.
After doing the Trial and Error experiments in a very large scale with hundreds of observation stations involved for about 30 years, Chinese researchers conclude that there are basically four types of precursors which can be observed and used for earthquake prediction :
Acturally, all the above four types of precursors reflect the
deformations happened in rock layyers, directly or indirectly. From my
experiences, I believe that the geoelectric precursors is the most
important one for the research.
In my opinion, the correct and practical earthquake prediction theory and a very effective earthquake prediction system could be achieved within the next 30 to 50 years if the right government(s) hire the right people to do the right thing with right equipments and enough research fund.
