Workload Profile. The performance of the system is dependent on how the load is delivered to the system. For example it is easier to achieve faster response times for a system that receive an regular arrival of work throughout the day compared to one that receive burst of traffic.
The January 17 2002 eruption of Nyiragongo volcano started suddenly at 8:25 local time. The eruption effectively involved a reopening and extension of the 1977 fault system and a renewed drainage of the lava lake, followed by the eruption of some magma from a deeper source.
Several fault systems meet at Nyiragongo, (1) the main N-S fault which was active in the 1977 and 2002 eruptions, (2) a NW-SE trending system linking Nyiragongo to Nyamuragira, (3) a NE-SW trending fault system including the Rushayo chain of scoria cones (formed in 1948), and possibly (4) a further fault approximately parallel but west of the Rushayo chain over which lie the scoria cones of Muhuboli and Gituro (see Fig.2).
