Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.When there was an earthquake, one of the dragons' mouths would open and drop its ball into a bronze toad at the base, making a sound and supposedly showing the direction of the earthquake. On at least one occasion, probably at the time of a large earthquake in Gansu in AD 143, the seismoscope indicated an earthquake even though one was not felt ...Earthquakes are measured using seismographs, which monitor the seismic waves that travel through the Earth after an earthquake strikes.. Scientists used the Richter Scale for many years but now ...5.3 Measuring and Locating Earthquakes Merry Wilson. Focus and Epicenter. The point of initial breaking or rupturing, where the displacement of rocks occurs along the rupture surface, is called the focus. The focus is always at some depth below the ground surface in the crust, and not at the surface, as shows in Figure 5.3.1.

The term seismograph usually refers to the combined seismometer and recording device.Wood-Anderson seismograph recorder, with synchronous AC motor that drives its drum at a constant speed of 1 mm per second. The Wood–Anderson seismometer (also known as the Wood–Anderson seismograph) is a torsion seismometer developed in the United States by Harry O. Wood and John August Anderson in the 1920s to record local earthquakes in southern California. Sometimes plate edges get stuck because of friction but the rest of the plate keeps moving, very slowly. 3. The energy and pressure that move the plates get stored up at the edges. 4. When the energy and pressure build up enough to overcome the friction, the plates move past each other along the fault. 5.Dec 20, 2022 · Measuring an earthquake’s intensity.
