4. Multidisciplinary Analysis



       Figure 4 describes a global data analysis of multiple signals. The seismoacoustic monitoring records short signals followed by barks before earthquake with 4 5 hours (figure 5).

            We use pairs of electrodes  in the ground to measure the telluric field (figure 4).  "Meteo data" are from our meteorological stations (Plostina, Vrancioaia, Nehoiu, Odobesti). NIEP's magnetometers network are monitoring the geomagnetic field. The DGD-K is from NOAA satellites network. The seismicity is present by ML and H (last two drawn, figure 4).  A Chaparral infrasound network records earthquake and other signals from air (see PLOR1).
                 The rocks' microcracks generate elastic waves under the tectonic stress. These waves have a small amplitude and a high frequency[6]. The next record was 20 Khz sample rate and the high pass filter is set at 5 Khz. Animals with a very good hearing ability react at these sounds (example in figure 5).

 The tectonic stress generates ions in epicentral areas. We have started to monitor + and - ions but we need time to make an estimation.
