The Seismological Observatory (SIS) of the University of BrasÃlia (UnB) located the explosion occurred in Beirut, today, 8/4/2020, at 15:10:42 (UTC), 12:10:42 (BrasÃlia time) and 18:10:42 (local time), using data from three infrasound stations of the International Monitoring System (IMS) network.
SIS - UnB collaborates with a United Nations Organization (CTBTO – Comprehensive Nuclear-Test-Ban-Treat Organization), based in Vienna - Austria, which aims to verify compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Brazil participates in this organization with data from its stations and with information gotten from the analysis and interpretation of data from the IMS Network with 321 geophysical sensors, which covers the entire planet. Any nuclear explosion, whether underground, underwater, or in the atmosphere, with a power equivalent to at least 1 kiloton of TNT (Trinitrotoluene - explosive material), can be detected by this network.
