      Multidisciplanary complex system for  monitoring clouds, aerosols and solar  radiation in corelation with Vrancea seismic activity

Phase 4 - 2016

     Phase 4 demonstrates the multidisciplinary monitoring functionality based on the evaluation of data provided by the integrated system. The results were disseminated through participation with posters at EGU 2016 and 2016 IBWAP, papers published or presented for publication in ISI journals.

      We analyze data from atmospheric monitoring (ionization, solar radiation, clouds, radon, electric field), telluric currents, magnetic field and satellites.
     The project highlights the interdependence between the ionization of atmospheric air, solar radiation, variations in visible light, temperature, humidity, atmospheric pressure, wind speed and direction, telluric currents, variations in local magnetic field and infrasound in the air, variations in electrostatic field, atmospheric anomalies, strain crust slope and ULF measurements.
       The goal of data analysis is to determine seismic precursors using local seismicity. Generally we perform detection of events related to the modification of monitored parameters which may be the result of tectonic stress, meteorological phenomenas or climate changes widely.
       One effect of geomagnetic storms refers to radio wave propagation. Kp index characterizes the magnitude of the disturbance and geomagnetic field geomagnetic storm. In next example we present the case  Kp = 7 (2016/10/25) and the recorded signals from the ground magnetic field, ionization of the atmosphere, ULF radio waves and solar radiation.

Kp = 7

We don't observe direct effects of the magnetic storm on ULF waves, ionization of air or solar radiation recorded on the ground. Magnetic field variations indicate a high geomagnetic perturbation amplitude.
       The following figures represent precursor  signals of earthquake from 23.09.2016 with Ml = 5.4R, H = 95 Km.

M54 Vrancea
The earthquake was preceded by a geomagnetic storm, variations of telluric field  and the ionization of air. At these data we add meteorological information, acoustic, ULF and CO2. Variations of radon are shown in the following figure.


In VRI station we recorded  ground vibrations from three acoustic sensors. Precursor noises occurred  with hours before the earthquake.

The data structure and events detection process are described in paper Detection of Events in a Multidisciplinary Network Monitoring Vrancea Area.
