Kharan Desert
Two sets of coordinates for the test location are available from different sources: the CTBT Prototype International Data Center [PIDC]; the US Geological Survey; and from satellite imagery that covers the actual test site as identified through imagery analysis and collateral information. In four of the five cases, the estimated seismic location was found to be to the northwest of the actual location as determined using satellite imagery. It is evidently the case that seismic monitoring can locate detectable underground nuclear weapons tests with an accuracy of a few dozen kilometers.
