UNITED NATIONS (Reuters) - Preliminary data collected by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in Vienna indicates that the magnitude of the seismic event detected in North Korea on Wednesday was lower than a similar one in 2013, the agency's chief said.

CTBTO Executive Secretary Lassina Zerbo told reporters by video link from Austria that the seismic event in North Korea appeared to have been a "slight down in terms of magnitude" compared with 2013. He said early information indicated a magnitude of 4.8 to 4.9 on Wednesday compared to 5.1 in 2013.
