Abstract(s)
Catastrophic events, such as wars and terrorist attacks, big tornadoes
and hurricanes, huge earthquakes, tsunamis, floods, and landslides, are always accompanied
by a large number of casualties. The size distribution of these casualties
have separately been shown to follow approximate power law (PL) distributions.
In this paper, we analyze the number of victims of catastrophic phenomena, in particular,
terrorism, and find double PL behavior. This means that the data set is better
approximated by two PLs instead of one. We have plotted the two PL parameters
corresponding to all terrorist events occurred in every year, from 1980 to 2010. We
observe an interesting pattern in the chart, where the lines, that connect each pair of
points defining the double PLs, are roughly aligned to each other.
