2023年1月27日 · A magnitude 8.4 earthquake struck 4 miles (6 km) from the coastal town of Atico, Peru, on June 23, 2001. At least 74 people were killed; more than a third of them were swept away by the...
Richter scale - Wikipedia
The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake.

2018年2月13日 · Magnitude: 8.8. This earthquake occurred off the coast of Ecuador and killed between 500-1,500 people from its ensuing tsunami. This tsunami affected the entire Pacific, reaching the shores of Japan approximately 20 hours later.
Earthquake Magnitude, Energy Release, and Shaking Intensity
Magnitude is the size of the earthquake. An earthquake has a single magnitude. The shaking that it causes has many values that vary from place to place based on distance, type of surface material, and other factors. See the Intensity section below for more details on shaking intensity measurements. Types of Magnitudes

Use the Earthquake Catalog Search to find earthquakes within a certain distance of any location. Expand "Advanced Options" and fill in the "Circle" fields. *United States earthquake lists (except "Top...") also include some earthquakes outside the U.S. since the search area is a rectangle.
Seismic magnitude scales - Wikipedia
Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location.
Richter Scale and Earthquake Magnitude - Science Notes and …
2023年7月19日 · The Richter scale is a logarithmic scale that measures the magnitude of an earthquake, originally developed by Charles F. Richter in 1935. It provides an objective measure of the energy an earthquake releases by quantifying the seismic waves produced.
