Furthermore, magnetometer surveys over the Zachary Cracks reveal a consistent, low-frequency electromagnetic pulse. Critics attribute it to telluric currents channeled by the linear fracture. Proponents of "solid state geophysics" suggest the piezoelectric grinding of quartz faces during micro-seismic events generates the signal. As of 2025, this remains a hotly debated topic in Geophysical Research Letters .
