This paper describes the concept of the EEIS and uses a sampling of strong earthquake ground motions with varying characteristics to illustrate some of its uses. The template is also used to provide a chronology of U.S. building code development from its design spectra perspective.
The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction.

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...

Which scale do you think is best? With the Richter scale, a single sharp jolt measures higher than a very long intense earthquake that releases more energy. The moment magnitude scale more accurately reflects the energy released and the damage caused. Most seismologists now use the moment magnitude scale.
