When plate boundaries occur in continental lithosphere, deformation is spread out over a much larger area than the plate boundary, so earthquakes occur away from the plate boundary and are related to strains developed within the broader zone of deformation caused by major irregularities in the fault trace.
One study that focused on risk assessment of mental illness and violence found that the stigma attached to such illnesses prevents those who require help from actually seeking it. The study pointed out that since 1983 there have been 78 mass shootings in the U.S., resulting in 547 deaths. The mental health of the shooters was the mediaâs prime focus in each case. Mental status aside, in the past decade alone, gun-related violence accounted for the deaths of over a quarter of a million people.
In the United States from January 1 to July 23, 2013, there have been 204 mass shootings. Mass Shooting Tracker, a crowd-sourced website that monitors gun-related deaths, defines a mass shooting as an incident âwhen four or more people are shot in an event, or related series of events, likely without a cooling off period.â Not all of these mass shootings resulted in a death. By that definition, forty of all fifty states have suffered some form of mass shooting since the beginning of the year. To date, New York, California, and Texas have been home to the highest number of mass shootings this year. Louisiana, where last nightâs incident took place, has been home to eight.
