You may not always feel the earth shaking, but California has earthquakes occurring all the time. Seismographic networks measure earthquakes by their magnitude, energy release and intensity. Years ago, all magnitude scales were based on the recorded waveform lengths or the length of a seismic wave from one peak to the next. But for very large earth...
When the Earth trembles, earthquakes spread energy in the form of seismic waves. A seismograph is the primary earthquake measuring instrument. The seismograph produces a digital graphic recording of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A network of worldwide seismographs detects and measures t...
An earthquake has one magnitude unit. The magnitude does not depend on the location where the measurement is made. Since 1970, the Moment Magnitude Scale has been used because it supports earthquake detection all over the Earth.
A second way earthquakes are measured is by their intensity. Earthquake Intensity measurement is an on-the-ground description. The measurement explains the severity of earthquake shaking and its effects on people and their environment. Intensity measurements will differ depending on each location’s nearness to the epicenter. There can be multiple i...
An earthquake is a sudden, rapid shaking of the earth caused by the shifting of rock beneath the earth’s surface. The size of an earthquake and the energy released by an earthquake will affect how much you feel it. Major earthquakes strike without warning, at any time of year, day or night. Prepare before the next big one: 1. Create an earthquake s...
Preparing your home BEFORE an earthquake is important to your safety. Decrease your risk of damage and injury from an earthquake by identifying possible home hazards. A seismic retrofit by strengthening your home’s foundation makes it more resistant to shaking. CEA offers earthquake home insurance premium discounts for houses and mobilehomes that h...
While it is wise to be prepared physically when the ground shakes, it’s also important to be financially protected. Without earthquake insurance, you place yourself at risk of losing everything or sustaining damages to your personal property that you cannot afford to repair or replace. Could you: 1. Pay your mortgage for a house that may need to be...

What does intensity mean in a earthquake?
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
Measures of acceleration are used to establish intensities up to VI, while the velocity is used to define the boundaries between higher intensity levels. Qualitative measures of intensity are based on accounts from people and observations of damage in areas affected by a quake.
Apr 3, 2014 · This Richter Scale calculator computes the magnitude of a seismic event such as an earthquake using the Richter Scale method, which expresses magnitude relative to a standard amplitude (S). The input is the intensity of the earthquake typically measured 100 kilometers from the epicenter of the event.
Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.
The present questionnaire contains pertinent questions about earthquake effects that enable a seismologist to evaluate the intensity of the earthquake in all parts of the shaken area; it also is designed specifically for computer processing.
