“…In studying natural earthquakes along the extension of Tanlu Fault in Russia, Mackey et al (2003) in indicated that the detection of natural earthquakes can be contaminated by industrial explosions. In this part of Russia, the industrial explosions include mining of tin, gold, and coal, as well as in the construction of roads, railways and dams.…”

The origin and detection of spike-like anomalies in soil gas radon time series

Desorption of radon is of short duration but longer than telluric noises and is usually accomplished in less than one minute based on our binary event counting with a 16 second interval. Adapting an hourly counting time schedule, telluric noises as well as transient variation of radon anomalies of a few hours duration can be excluded but not the spike-like anomalies of a few minutes duration. The time series of soil gas radon, as recorded continuously in a redesigned ditch located inside an active fault zone, has sporadic spike-like anomalies. The anomalies could represent desorbed radon from shallow sources as observed from a similar detecting system located near a construction site. Radon release due to compressive stress is related to compressive back-filling activities. Spike-like anomalies, on the other hand, are related to caisson auguring shear activities. Charge transfer related to electrokinetic potential phenomena may have resulted in the sudden radon releases and caused spike-like anomalies. The timing of the anomalies provides good information on the timing of electokinetic potential change as a result of outward propagation of stress from hypocenter. With multiple monitoring stations, the location, timing, and magnitude of the incoming earthquake can then be calculated or graphically derived.

“…Note the sparse station spacing used in these preliminary studies compared to the station spacing in the BASE deployment ( Figure 1). The time-of-day discriminant [7], [8], was used to verify the catalog consistency and evaluate general trends of the region. The time-frequency discriminant helps identify delayed-fired sequences common in mining regions and separates the largest mining events from background seismicity [9], [10].…”

(377ABW-2013-0028 dtd 09 Jan 2013) SUPPLEMENTARY NOTES ABSTRACTWe used data from the Bighorn Arch Seismic Experiment (BASE) to determine P-wave velocity structure and assess regional explosion discriminants in north-central Wyoming. BASE is a multi-scale, hybrid active/passive seismic experiment designed to determine crust and mantle structure below the Bighorn Mountains. North-central Wyoming experiences a spectrum of manmade and natural events, from regional earthquakes and teleseisms to mine blasts and single fire shots, making the region a compelling natural laboratory in which to investigate implications for regional discrimination. The velocity structure across the region is calculated through tomographic inversion of arrival times from 21 controlled-source single-fired seismic shots. The detailed velocity models can also be used to investigate the degree of spatial sampling of the seismic wavefield needed to characterize 3D wave propagation effects. For the discrimination study, we used the single-charge explosions from the BASE experiment, mining explosions, and ~40 earthquakes to test seismic discriminants using USARRAY broadband data and data recorded at station RSSD. An amplitude ratio of Pg (6-12 Hz) versus Lg (6-12 Hz) mostly separated the earthquakes from the explosions. Lg spectral ratios also separated the explosions from the earthquakes, but not as well as the Pg/Lg ratio.
