• Mid-infrared emission prior to strong earthquakes analyzed by remote sensing data (2004, background): “Using impact experiments it has been shown (Freund, 2002) that igneous rocks, granites as well as quartz-free rocks, contain defect electrons in the oxygen sublattice, also known as positive holes (p-holes): • the p-holes are electronic charge carriers but they are normally dormant in the rocks in…”
• Ionosphere plasma bubbles and density variations induced by pre‐earthquake rock currents and associated surface charges (2011, methodology): “[6] Laboratory experiments [Freund, 2000, 2002; Freund and Sornette, 2007; Freund et al., 2009; Freund, 2010] demonstrated that, as rocks are subjected to stress, rocks can activate positive holes (h•) as charge carriers and generate electric currents along the stress‐gradient direction with…”
• An improved coupling model for the lithosphere‐atmosphere‐ionosphere system (2014, background): “…(2) a stressed rock-atmosphere–ionosphere coupling model [Kuo et al., 2011] based on experimental evidence of stressed rock currents [Freund, 2000; Freund, 2002; Freund, 2010, 2013], and (3) ionosphere dynamics with imposed zonal (west-east) electric field [Zolotov et al., 2011; Namgaladze et…”
• Electric currents streaming out of stressed igneous rocks - A step towards understanding pre-earthquake low frequency EM emissions (2006, background): “We know that these PHPs can be activated by stress and that they release mobile p-hole charge carriers (Freund, 2002).”
• Rocks That Crackle and Sparkle and Glow: Strange Pre-Earthquake Phenomena (2003, methodology): “Two velocity ranges were used: low velocities of the order of 100 m/sec with 3.2–6.3-mm stainless steel spheres, impacting in air, and medium velocities of the order of 1.5 km/sec with 6.3-mm aluminum spheres, impacting in vacuum (Freund, 2000, 2002a).”
