An example of an earthquake swarm is the 2004 activity at Yellowstone National Park. In August 2012, a swarm of earthquakes shook Southern Californias Imperial Valley, showing the most recorded activity in the area since the 1970s.Sometimes a series of earthquakes occur in what has been called an earthquake storm, where the earthquakes strike a fault in clusters, each triggered by the shaking or stress redistribution of the previous earthquakes. Similar to aftershocks but on adjacent segments of fault, these storms occur over the course of years, and with some of the later earthquakes as damaging as the early ones. Such a pattern was observed in the sequence of about a dozen earthquakes that struck the North Anatolian Fault in Turkey in the 20th century and has been inferred for older anomalous clusters of large earthquakes in the Middle East. Intensity and magnitude of earthquakes
Shaking of the earth is a common phenomenon that has been experienced by humans from the earliest of times. Before the development of strong-motion accelerometers, the intensity of a seismic event was estimated based on the observed effects. Magnitude and intensity are not directly related and calculated using different methods. The magnitude of an earthquake is a single value that describes the size of the earthquake at its source. Intensity is the measure of shaking at different locations around the earthquake.
However, most common research into ventriculitis has been focused on the main points of causation, demographic information, and effectiveness of treatments and prevention methods. Causation
One of the key areas of research for ventriculitis is discovering and defining exactly what causes it. There are many bacterial and viral infections that could cause inflammation of the ventricles, but researchers are trying to define which are the most common pathogens, the risk levels associated with various medical operations and procedures, and why the symptoms vary so much on a case-by-case basis. Answering these questions will allow doctors to not only better understand ventriculitis, but better treat and prevent it as well. Demographics
Currently, there is very little understanding as to who is at increased risk for ventriculitis, other than those who have undergone neurosurgery or procedures involving brain exposure. Even then, current clinical practices cant predict which patients will be affected. In order to predict which populations should be focused on, researchers must gather more case information about who is diagnosed with ventriculitis and how they present. In essence, the medical community must compile data of as many details as possible from each case so that more generalized conclusions may be drawn. Treatment and prevention
So little is currently known about how ventriculitis should be defined and those it affects that even less can be known about prevention methods. While treatment is fairly standard for any infection to some degree, prevention is a different matter.
