GPH 111 Volcano Report 10-6-10 The physical dynamics leading up to the eruption of Nyiragongo volcano in 2002 are quite interesting. About a year earlier, a neighboring volcano erupted for about two weeks. After this eruption, seismic activity did not slow down, as it usually does, and due to the lack of seismic stations and amount of volcanoes in the area, it was impossible to determine exactly where the activity was coming from. This ongoing activity, however, caused local scientists to continue to monitor the local volcanoes, including Nyiragongo. On October 7 th , 2001, a magnitude 4.0 tectonic earthquake

Unformatted text preview: occurred in a nearby city. In December, ground temperatures had risen to about 28 degrees Celsius. Also, people started to take notice to increase smoke coming from the volcano. Scientists noted that there was also increased fracturing and seismic activity on the upper southern slopes. This activity was especially apparent between the 4 th and the 17 th . The eruption was ultimately triggered by tectonic spreading of the Kivu rift causing the ground to fracture, allowing lava to flow from ground fissures out of the crater lava lake....
