Multiparameters include Radon, Helium, Co2, Na, Hg, Water level; PH Value etc.
Prof Virk,
Initially, people thought that a precursor of earthquake must be embedded in the Mother earth itself but they didn't realise that Mother earth is a huge system and by the time, it will show a precursory signature, it is already too late. Please note that there is absolutely no need of any science and technology after an earthquake strikes. Therefore, please do not look at the Mother earth for a precursory signature. It has to be seen in the air close to the earth (air is millions times lighter than the Mother earth itself) and its density is thousand times lower than the density of earth. Thus, air provides an amplification of precursory signatures. Moreover, Nature is great-it has made earth as a heterogeneous structure, which means any shock or seismic energy propagating before an earthquake, it will scatter, while air is a homogeneous mixture, thus the impact can be monitored without any ambiguity.
This is the reason that you may choose thousands of elements to measure precursor inside the earth, they will not be able to reveal precursor with a degree of confidence.

The solution offered is too simple to be useful. In fact, multiparametric approach is based on recording of precursory signals from all sources including mother Earth and Air.
