Sometimes data are too poor to compute a reliable depth for an earthquake. In such cases, the depth is assigned to be 5 km. In Oklahoma, reliable depths tend to average 5 km or close to it. For example, if we made a histogram of the reliable depths in this area, we'd expect to see a peak around 5 km. Thus, if there are not enough data, or data are too poor, 5 km is a reasonable guess. The USGS is responsible for monitoring earthquakes all over the world.

On Saturday morning, the Oklahoma Geological Survey said in a statement that there have been reports of strong shaking in the immediate area and across Oklahoma City. Connecting the dots, Walter added, the quakes follow a fault identified by researchers. The area has seen an uptick in earthquakes in recent years, he said. Human activities, including fracking, have fueled the increase. While the area saw its peak in activity in — derived from wastewater disposal used in oil and natural gas production pumped deep below fracking areas — smaller seismic activity, often unfelt by residents, has continued to occur. However, there doesn't appear to have been wastewater disposal in the area as of late. On Friday night a 4. The USGS recorded a 2.

Risk is the potential that exposure to the hazard will lead to a negative consequence such as loss of life or economic loss. To illustrate the difference, consider the following two examples. Bottom line: High earthquake hazard does not mean high risk.

On Saturday morning, the Oklahoma Geological Survey said in a statement that there have been reports of strong shaking in the immediate area and across Oklahoma City. Often, we have to turn to more complex analysis and compare human activities with earthquake occurrence to identify such cases. This means that because most of what is being released is the natural energy stored within the Earth on an existing fault system, it is often not possible to readily distinguish a naturally occurring earthquake from a triggered earthquake. If you felt an earthquake, let us know. Search Earthquake Catalog View historic seismicity, find past earthquakes that meet your criteria. Home U. As the P waves arrive at your location, they cause the ground surface around you, and your floor, to vibrate up and down, just like a loudspeaker cone. Why do so many Oklahoma earthquakes occur at a depth of 5km? Induced earthquakes are more accurately described as triggered earthquakes. Skip Side Navigation.
