GIS files (16 MB ZIP file) This database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Myr). At the time the Quaternary Fault and Fold database was established (1993), the Quaternary time ...The earthquake events are scaled either according to the magnitude or intensity of the shock. The magnitude scale is known as the Richter scale. The magnitude relates to the energy released during the quake. The magnitude is expressed in absolute numbers, 0-10. The intensity scale is named after Mercalli, an Italian seismologist. The intensity ...During an earthquake, a rupturing fault produces several different kinds of waves that carry energy away. from the epicenter like ripples from a rock thrown into a pond. The fastest-moving seismic waves (primary or P-waves) travel about 3.7 miles per second and generally do not produce strong shaking. P-waves are followed by slower moving, …The Richter scale is logarithmic, with each step up the scale marking a tenfold increase in quake strength—a 4.0 quake on the Richter scale, for instance, releases 10 times the energy of a 3.0 earthquake. The problem was that for large quakes—over 7.0 on the scale—the Richter scale was less reliable.Two scales are used commonly to measure earthquake strength. You can measure an earthquake either by its size where the rock slipped, or by the amount of shaking that is experienced at a place that interests you. Both measures are used. The measure of the size of the earthquake where it occurred is the “magnitude.”.Sep 29, 2023 · A modified Mercalli intensity scale is used to quantify the earthquake's effects. That's why you can't directly convert the Richter or Magnitude scale to the Mercalli scale — although the released energy, local geology, terrain, depth of an earthquake and distance from the epicenter are all still the same. Thus, the Mercalli scale describes ... Earthquakes can have various effects, including ground shaking, damage to man-made structures, fires and hazardous chemical spills, landslides and avalanches and the generation of tsunamis in coastal areas. The severity of these effects depends on factors such as the earthquake’s magnitude, depth and local geology.
