The August 16, 1997 earthquake near the former Russian test site on Novaya Zemlya recorded by the IRIS GSN station Kevo (KEV). Data are bandpass-filtered at 5-10 Hz. The P/S spectral ratio for this event is relatively small (earthquake-like) compared with KEV recordings of previous nuclear explosions on Novaya Zemlya. The provisional International Data Center for the CTBT reports a magnitude of ML 3.8 and a location on the Kara Sea, about 100 km southeast of the test site. (see article by P. Richards and W.Y. Kim, Nature, Vol. 389, 23 October 1997)
