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.
Few volcanoes are as spectacular as Mount Nyiragongo. Known for its active lava lake and (relatively) frequent eruptions, this incredible volcano has the potential for widespread disaster. Unfortunately, political unrest prevents the scientific community from studying the dangerous volcano in depth.
