— There is increasing evidence that earthquakes produce electromagnetic signals observable at the surface in the extremely low to very low freqency (ELF-VLF) range often in advance to the main event. These precursors are candidates for prediction purposes. Laboratory experiments confirm that material under load emits an electromagnetic signature, the(More)
Monitoring electromagnetic waves in the Ultra Low Frequency (ULF) range between 1 mHz and 1 Hz is essential for an understanding of the processes in the earths magnetosphere. Also earthquake prone areas are under suspect to emit precursor ULF signals. We discuss a receiving system using a solenoid sensor and Negative Impedance Converter (NIC) as front end.(More)
