Scaling similarities of multiple fracturing of solid materials

Abstract. It has recently reported that electromagnetic flashes of low-energy
-rays emitted
during multi-fracturing on a neutron star, and electromagnetic pulses emitted in the
laboratory by a disordered material subjected to an increasing external load, share
distinctive statistical properties with earthquakes, such as power-law energy distributions
(Cheng et al., 1996; Kossobokov et al., 2000; Rabinovitch et al., 2001; Sornette and Helmstetter, 2002).
The neutron starquakes may release strain energies up to 
erg, while, the
fractures in laboratory samples release strain energies approximately a fraction
of an erg. An earthquake fault region can build up strain energy up to approximately
erg for the strongest earthquakes. Clear sequences of kilohertz-megahertz
electromagnetic avalanches have been detected from a few days up to a few hours prior
to recent destructive earthquakes in Greece. A question that arises effortlessly
is if the pre-seismic electromagnetic fluctuations also share the same statistical
properties. Our study justifies a positive answer. Our analysis also reveals "symptoms"
of a transition to the main rupture common with earthquake sequences and acoustic
emission pulses observed during laboratory experiments (Maes et al., 1998).Full Article (PDF, 2395 KB) Special Issue
