... 260 earthquakes and 26 underground nuclear explosions recorded at the broadband, digital station WMQ in western China and over 120 earthquakes and five nuclear explosions at station AAK in Kyrgyzstan. The explosions are from the Kazakh Test Site ( KTS ) and Lop Nor, China. The earthquakes are mostly...

... at 19:52:16 UTC with magnitude m b  4.8 within 30 km of China’s Lop Nor nuclear test site. Recent earthquakes in the region are well documented (e.g., Selby et al. , 2005 ; Fox et al. , 2012 ) but accurate location, and unequivocal identification as an earthquake at a depth that excludes...

..., which have previously been shown to be reliable discriminants. For data, we use 271 earthquakes from northwest China, 25 nuclear explosions from the Kazakh test site (KTS), and one nuclear explosion from the Lop Nor test site recorded at station WMQ. We also use 185 earthquakes from the same region...

... 1976 and July 1996 at the Lop Nor test site in the southern Xinjiang province of China. In addition to first- and later-arriving phase-pick data from the International Seismological Centre and Chinese bulletins, we use waveform cross-correlation methods to measure relative arrival times between...

...Mark D. Fisk Abstract Locations are estimated of 11 underground nuclear explosions conducted between 26 May 1990 and 29 July 1996 at the Lop Nor test site in western China. To perform the analysis, seismic recordings were obtained from the Center for Monitoring Research (CMR), U.S. National Data...

...Jiajun Zhang Abstract Complete waveforms with periods longer than 30 sec recorded at teleseismic and regional distances are used to characterize the source of several earthquakes and underground nuclear explosions in the Lop Nor area, Xinjiang, China. Propagation effects of Earth's heterogeneities...

... paths between certain surrogate-operational station combinations do play a role in the effectiveness of the method. We used this methodology to predict explosion values at the Lop Nor nuclear test site in China using a suite of nearby calibration earthquakes to calculate IACF values. The results...

... are collected from 157 known earthquakes, 215 unknown events (presumed earthquakes and possibly some industrial explosions), and 18 known nuclear explosions (1 from the Chinese Lop Nor test site and 17 from the East Kazakh test site). A feature selection technique is used to find the best combination...

...Figure 9. ▴ Travel time residuals at ISC bulletin stations (N ∼700) relative to ground truth origin (red circle) for the 1996/06/08 Lop Nor China nuclear test. Worldwide ISC P residuals tend to be biased negative on average from Lop Nor explosions, but positive residuals are apparent in some...

... at the Chinese Lop Nor test site. These events were very sparsely recorded by stations located within 1600 km, and in each case only three or four stations were available in the regional distance range. We have utilized a regional distance seismic waveform method fitting long‐period, complete, three‐component...

The data were recorded at the medium-aperture array station YKA for an earthquake in western China, close to the former Chinese nuclear test site at Lop Nor (22 January 2003 earthquake in Table  1...
