Alachua County Fire Rescue (ACFR) and High Springs Fire Department responded to a home in High Springs Monday morning for reports of a dog stuck in a sinkhole.
Crews arrived shortly after 6:30 a.m. to the home located at 22210 NW 188th St. There, they located Sam the dog at the bottom of a 40-foot sinkhole.
Lt. Brian Ferguson of ACFR used an extension ladder and rope system to descend into the hole and save the scared pup, using bacon to calm his nerves.
Sam's owner says that although he's tired, he doing fine.
This is ACFR's second sinkhole-related technical rescue in two days. While ACFR says sinkholes are common in the area, the recent increase in rain is likely a contributing factor in both scenarios.
So, most of the Earth's crust can become highly conductive if subjected to mechanical stress/shock, for example the type of stress due to the slowing down and opening up of the Earth's lithosphere described above. When high conductivity is reached, electric current can occur between ground regions of different electric potential.1 This current being fed, among other factors, by the change in surface-core E-field mentioned previously.
At this point a second phenomenon called piezo electricity might itervene. Some crystals, in particular quartz which is very frequent in granite rocks,2 will deform if subjected to electric current (that's almost the reverse of the above described phenomenon where mechanical deformation triggers electric current).
One could thus hypothesize that earthquakes are not unlike underground lightning. Earthquakes being to underground electric phenomenon what lightning is to atmospheric electric phenomenon: a simple charge rebalancing process generating some mechanical side effects: air waves (thunder) for lightning and crustal waves (seismic tremors) for earthquakes.
Footnotes:
1 Such effects, combined with emissions of gasses from inside the earth, another consequence of 'opening up', could be another factor in the eruption of anomalous fires and explosions.
2 Interestingly most mountain range are made of granite, concomitantly mountain range are also some of the most quake prone geological formations.
