| Description |
The Goma volcano Observatory seismic network is located in the Kivu Rift region, which is bordered by the Democratic Republic of the Congo and Rwanda. The active volcanoes Nyamulagira (Africa's most active) and Nyiragongo (home to the world's largest persistent lava lake) threaten the city of Goma and surrounding agglomerations, and destructive earthquakes can also strike the region. This network succeeded the KivuSNet, which ran from 2013 to 2021. The Goma Volcano Observatory Seismic Network (GvoSnet) is a network built, operated, and managed by the Democratic Republic of the Congo (DRC) through the Goma volcano Observatory (GVO). GvoSnet deployment began in May 2022 with the installation of the first two telemetered stations. It had grown to nine telemetered stations by the end of July 2022, and twelve by September 7, 2022. 17 stations is expected to be operational with real-time data transmission by July 2023. The broadband GVO seismic network study seismic activity in the Kivu Rift, specifically the Nyiragongo and Nyamulagira volcanoes, as well as the seismicity of Lake Kivu. These volcanoes pose serious geohazards to the people of Goma and Sake in the Democratic Republic of the Congo, as well as the Gisenyi district in Rwanda. Lake Kivu is also a significant geohazard because it is one of only three lakes in the world that can experience limnic eruptions due to high methane and carbon dioxide gas concentrations dissolved in its water. The Goma Volcano Observatory Seismic Network (GvoSnet) is a network installed, operated, and managed by the Government of the Democratic Republic of the Congo (DRC) through the Goma volcano Observatory(GVO). GvoSnet deployment began in May 2022 with the first two telemetered stations. By the end of July 2022, it had grown to nine telemetered stations, and by September 7, 2022, it had grown to twelve. The DRC government contributed five seismic stations, the Lake Kivu Monitoring Program three, and MONUSCO four. Data are collected in situ at each station at 50Hz and 200Hz sampling frequencies and telemetered in real-time to the Goma Volcano Observatory station base at 50Hz sampling frequency. Most seismic sensors are installed in the center of the hut on a concrete seismic pier with variable surface sizes (ranging from around 0.5 m to 1.5 m). The seismic piers have been anchored as deeply as possible, reaching bedrock in most cases, and have been decoupled from the observation hut's concrete floor. At GOM2 station, the sensor is installed in vaults 2-3 m deep. Table 1 Station List for Goma Volcano Observatory Seismic Network |
