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.
The Surtsey Eruption 1963-1967. The Surtsey eruption is among the longest eruptions to have occurred in Iceland in historical times. The first sign of an eruption came early in the morning of November 14, 1963, at a site approximately 18 km southwest of Heimaey, the largest of the Vestmannaeyjar (Westman Islands). total of 1.1 kmÂ³ of volcanic products arose from the Surtsey eruption, of which 60-70% were tephra and 30-40% lava. In many respects the Surtsey eruption is comparable to eruptions that led to the formation of hyaloclastite (palagonite) mountains in Iceland during the Ice Age.
