Intensities are evaluated using the Modified Mercalli Intensity Scale of 1931, which contains levels of effects ranging from intensity I, barely perceptible, to intensity XII, total damage.
- Magnitude. Sketch of a traditional seismometer. (Public domain.) The time, location, and magnitude of an earthquake can be determined from the data recorded by seismometer.
- Energy Release. Earthquake magnitudes and energy release, and comparison with other natural and man-made events. (Courtesy Incorporated Research Institutes for Seismology, IRIS.)
- Intensity. Did You Feel It? map for the M6.0 Napa, California earthquake on August 24, 2014. The earthquake epicenter is shown as a star, and the geocoded intensities are shown as small colored squares.
- Examples. These examples illustrate how locations (and depth), magnitudes, intensity, and faults (and rupture) characteristics are dependent and related.

damage-intensity relation is very important to be used for predicting the damage level due a specified to earthquake. The damage level is needed by The Government to develop an emergency and reconstruction budget plan for earthquake disaster in future. SUMMARY: Keywords: Earthquake, damage assessment, earthquake intensity. 1. INTRODUCTION . On 30 September 2009an earthquake with 7.6 on the Richter scale was shock in West Sumatra. The
It is composed of 12 increasing levels of intensity which range from ground shaking to catastrophic destruction. The lower levels of the intensity scale indicate the effect of earthquake felt by people, and the higher levels indicate the observed structural damage. Table 1 describes the 12 levels of Modified Mercalli Intensity Scale.
Intensity is another measure of earthquake severity which is commonly measured by assessing the degree of damage a seismic event causes. This includes damage to structures,

Jan 01, 2020 · This function is defined by (5) L = ∏ i = 1 N [F k (a i)] x i [1 − F k (a i)] (1 − x i) where F k (a) increases when damage occurs and 1 − F k (a), the probability of not experiencing a damage, increases when damage does not occur for the earthquake intensity of a i.
