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.
Dacite and rhyodacite was erupted from at least 25 vents distributed over 120 sq km. Eruption of Mount Mazama. Crater Lake was formed 5677 Â± 150 B.C. when 50 cubic km of material was erupted from Mount Mazama. The climactic, caldera-forming eruption of Mount Mazama can be divided into two phases: single vent and ring vent. Onset of collapse of the caldera probably caused the switch from the first to the second phase of eruption.
