QuakeFinder
From Wikipedia, the free encyclopedia
QuakeFinder is a company focused on developing a system for earthquake prediction. QuakeFinder operates as a project of aerospace engineering firm Stellar Solutions,[1] and by subscriptions and sponsorships from the public.[2]
In the 1970s, scientists were optimistic that a practical method for predicting earthquakes would soon be found, but by the 1990s continuing failure led many to question whether it was even possible.[3] Extensive searches have reported many possible earthquake precursors, but, so far, such precursors have not been reliably identified across significant spatial and temporal scales.[4] Based on the results of this research, most scientists are pessimistic and some maintain that earthquake prediction is inherently impossible.[5]
QuakeFinder has deployed a network of sensor stations that detect the electromagnetic pulses the team believes precede major earthquakes.[6] Each sensor is believed to have a range of approximately 10 miles (16 km) from the instrument to the source of the pulses.[7] As of 2016, the company says they have 125 stations in California,[8] and their affiliate Jorge Heraud says he has 10 sites in Peru.[9] Using these sensors, Heraud says that he has been able to triangulate pulses seen from multiple sites, in order to determine the origin of the pulses. He said that the pulses are seen beginning from 11 to 18 days before an impending earthquake, and have been used to determine the location and timing of future seismic events.[10][11]
However, insofar as a verifiable prediction would require a publicly-stated announcement of the location, time, and size of an impending event before its occurrence, neither Quakefinder nor Heraud have yet verifiably predicted an earthquake, much less issued multiple predictions of the type that might be objectively testable for statistical significance.
