Fractures of the coronoid rarely occur in isolation. They usually occur in combination with a radial head fracture, a dislocation of the elbow, or both (terrible triad of the elbow).Large coronoid fractures often are associated with persistent elbow instability even after reduction of the dislocation.
Hydrothermal Vents. Measurement of tectonic plate movements. The amount of tectonic plate movement is measured using Global Positioning System (GPS) satellites and a network of GPS receivers. This technology allows scientists to measure plate movements as small as a few millimeters per year. click here to plot REAL-TIME data and visualize tectonic plate movement.
How do scientists measure earthquakes? With a really big ruler? No, not quite. There are two ways in which scientists quantify the size of earthquakes: magnitude and intensity. You have probably heard of the Richter scale which is still used for small earthquakes, but most large earthquakes are now commonly reported using the moment magnitude scale (see below). Richter scale
