Magnitude, and Intensity
• Absolute Magnitude (M): Brightness of the star if it were observed from a fixed distance (32 6 light years) In later chapters we will see how to work with distance and absolute magnitude • Apparent magnitude versus intensity (flux) m = apparent magnitude I = intensity • Intensity versus apparent magnitude 2 5 B AB A I mm Log I
MEASURES OF AN EARTHQUAKE, MAGNITUDE AND INTENSITY Measures
earthquake-intensity and magnitude In many instances, the two terms are erroneously used interchangeably Intensity is based on post-earthquake damage surveys, is a descriptive scale, is indicative of shaking at that place, is written in Roman numerals, is space-dependent, and varies from point to point in the affected area

Magnitude vs Intensity 4-12 (Lisa Wald & Wendy Shindle, Oct 2001 (rev Jul 2004) Key Points: -An earthquake has one magnitude, but many intensities -The intensity of shaking generally decreases with distance from the hypocenter -The intensity of shaking also is influenced greatly by the type of underlying
EARTHQUAKE MAGNITUDE AND INTENSITY - Maintenance
the method for calculating Richter magnitude and for mapping seismic-shaking intensity MAGNITUDE Magnitude is a measurement of the energy released by an earthquake The first earthquake-magnitude scale was the Richter scale, devised by Charles F Richter, a seismologist at the California Institute of Technology The Richter scale is based on the
Digital Atlas of Idaho Geology: Earthquake Concepts
The magnitude of an earthquake 1000 times stronger than an earthquake with a magnitude of 5 6 would have a magni-tude of 8 6 on the Richter scale 8 What is the difference between magnitude and intensity? Magnitude refers to the amount of energy releases by an earthquake; intensity refers to how much damage was done
Learning Earthquake Tip 3 Earthquake Design and Construction
Basic Difference: Magnitude versus Intensity Magnitude of an earthquake is a measure of its size For instance, one can measure the size of an earthquake by the amount of strain energy released by the fault rupture This means that the magnitude of the earthquake is a single value for a given earthquake On
EARTHQUAKE MAGNITUDE, INTENSITY, ENERGY, AND ACCELERATION By
EARTHQUAKE MAGNITUDE, INTENSITY, ENERGY, AND ACCELERATION (Second Paper) By B GUTENBERG AND C F RICHTER ABSTRACT This supersedes Paper 1 (Gutenberg and Richter, 1942) Additional data are presented Revisions involving intensity and acceleration are minor The equation log a = I/3 - ~ is retained The
Luminosity, Flux and Magnitudes - Cornell University
The magnitude scale is logarithmic An increase in magnitude by 2 5 means an object is a factor of 10 dimmer, e g a 0 mag star is 10 times brighter than a 2 5 mag star a 0 mag star is 100 times brighter than a 5 mag star A2290-13 Flux and Magnitudes 18 Example magnitudes A dark adapted person with good eyesight can see to ~ 6th magnitude
