  1. Joseph Nyago Seismological Network Department of Geological Survey and Mines, P.O Box 9, Entebbe - Uganda An overview of Uganda Seismological Network and current activities IRIS Workshop on Managing Waveform Data and Related Metadata for Seismic Networks’, November 8-16, 2009 in Helwan - Cairo, Egypt

  2. Outline • Introduction • History of destructive earthquakes in Uganda • Earthquake epicenters 1900-2007 • Station coverage • Seismic instrumentation • Data collection, analysis and interpretation • Way forward • Acknowledgements IRIS Workshop, Cairo-Egypt

  3. Seismological monitoring activities in Uganda as early as 1925 with a Milne-Shaw seismograph station at Entebbe. It was later re-established in 1989 under Uganda National Seismological Network. UNESCO donated 3 micro-earthquake (MEQ-800) analogue seismograph and short period seismometers. In 1999, the US Government through University of California San Diego (IRIS-IDA Project) installed a Global Seismographic station (MBAR) at Kyahi-Mbarara. In 1999, International Programs in Physical Sciences (IPPS), Sweden donated 3 Orion Nanometrics seismographs and broadband seismometers. Introduction IRIS Workshop, Cairo-Egypt

  4. History of destructive earthquakes in Uganda 9th July 1912: Kitgum earthquake, magnitude 6.7; 2nd October 1929: Toro earthquake in western rift, magnitude 5.9; 18th March 1945: Sembabule earthquake, magnitude 6.0; 20th March 1966: Toro earthquake, magnitude 6.6; 7th September 1990: Lake Victoria earthquake, magnitude 5.0; 9th October 1991: Butiaba Port earthquake, magnitude 5.3; 5th February 1994: Kisomoro earthquake, magnitude 6.2 (8 people lost lives, caused destruction of property in 3 western districts worth 61 million US dollars). IRIS Workshop, Cairo-Egypt

  5. Earthquake epicenters 1900-2007 IRIS Workshop, Cairo-Egypt VSAT antenna at site NDC-N180

  6. Seismic Network IRIS Workshop, Cairo-Egypt VSAT antenna at site NDC-N180

  7. SeismicInstrumentation IRIS Workshop, Cairo-Egypt

  8. SeismicInstrumentation IRIS Workshop, Cairo-Egypt VSAT antenna at site NDC-N180

  9. SeismicInstrumentation IRIS Workshop, Cairo-Egypt

  10. Data collection, analysis and interpretation Seisan earthquake analysis software ( both linux and windows versions) is used to analyze waveform data from the IRIS station (MBAR) and waveform data from 3-component broadband (nanometrics) stations (ENT, HOI, KIL). IRIS Workshop, Cairo-Egypt

  11. Way forward ?? Upgrading the existing stations with improved event detection capability and modern instrumentation to ensure; Real-time waveform data transmission and availability Automatic waveform processing Automatic event location Expanding on the existing network by increasing on the number of stations to ten (10) to ensure accurate event location.
