The city of Goma and the area of Nyiragongo located at the bottom of the volcano are and will remain high risk areas. Since January 2009, the Nyiragongo and Nyamulagira volcanoes have been showing the following signs: recurrent seismic swarms of volcanic nature; great range volcano tremors at the seismographic station of Rusayo, where they happened more frequently than in other stations. This means that the volcano tremors mainly come from Nyiragongo, which lake of lava is very active.
