Earthquake magnitude measurement

.

There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between the earthquake and the recording seismometer so that the calculated magnitude should be about the same no matter where it is measured. A new geological phenomenon has startled Morocco. A few days ago, a huge sinker suddenly appeared in some agricultural fields located around Had Oulad Frej, in the province of El Jadida. About 200 km from the epicenter of the terrible 6.8 magnitude earthquake that a few weeks ago killed about 3,000 people, mainly in the High Atlas.Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs. Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10.

Find 23 millimeters on the right side of the chart and mark that point. Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude. The point where your ruler crosses the middle line on the chart marks the magnitude (strength) of the earthquake.03‏/07‏/2022 ...

From Richter's (1958) book, Elementary Seismology. The first earthquake magnitude scale was invented by Charles Richter for southern California in 1935. Unlike seismic intensity, which measures the strength of shaking and varies according to distance from the quake and other factors, the magnitude is intended to measure the intrinsic size of an earthquake. Answer a. For the 1933 earthquake in Japan, what value of E gives a Richter number M = 8.9? To find the value of E, we need to rearrange the given formula and solve for E.

However, in measuring the seismic moment, the Chilean quake was larger, giving M w of 9.5 versus the M w of 9.2 for the Alaskan earthquake. The reason is that the Chilean earthquake released more energy, but in the Alaskan ... In 1979, as geologists developed more accurate techniques for measuring energy release, a new scale replaced the Richter: the moment magnitude, or MW scale, which seeks to measure the energy released by the earthquake.
