The Director of Solid Earth Physics Research Institute
Prof. P. Varotsos has been the Director of Solid Earth Physics Research Institute at the Department of Physics of the National and Kapodistrian University of Athens from 1994 to the present time.
Moreover, Prof. P. Varotsos has been the Director of the Laboratory of Physics of the National and Kapodistrian University of Athens from 2007 to 2014.
Prof. P. Varotsos published over than 250 papers in refereed journals, a number of articles in international books, 3 monographs in English and 2 monographs in Greek. He serves as reviewer in Physical Review Letters, Physical Review B, Journal of Applied Physics, Journal of Geophysical Research, Geophysical Research Letters, Tectonophysics and in several other scientific journals.
The three monographs published in English by Prof. P. Varotsos are the following:
- P. Varotsos and K. Alexopoulos, Thermodynamics of Point Defects and their relation with the bulk properties, North Holland (1986), 474 pages.
- P. Varotsos, The Physics of Seismic Electric Signals, TerraPub, Tokyo (2005) 338 pages
- P. A Varotsos, N. V. Sarlis and E. S. Skordas, Natural Time Analysis:The new view of time. Precursory Seismic Electric Signals, Earthquakes and other Complex Time-Series, Springer-Verlag, Berlin Heidelberg (2011) 449 pages.
Example of precursory electric signals. An SES activity recorded at Ioannina station (IOA) on April 18, 1995 (raw data collected by the real-time telemetric network; the scales are in mV) which preceeded the Kozani-Grevena 6.6 earthquake that occurred on May 13, 1995. All dipoles are installed at IOA, except the one labeled ASS (given to distinguish the disturbances induced by variations of the Earth's magnetic field). The arrow labeled “increase” indicates the direction of increasing ΔV measured in mV.
