Earthquake rating system
Sensitive instruments, which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. Modern systems precisely amplify and record ground motion (typically at periods of between 0.1 and 100 seconds) as a function of time. Magnitude is the size of the earthquake. An earthquake has a single magnitude ... Early earthquake warning systems typically use seismometers to detect incoming fast P-waves. When shaking is felt, a signal is sent to the local seismic authority, which rapidly sends out an alert to those in the region who are likely to feel shaking, hopefully before the more damaging S-waves arrive.USRC Earthquake Rating Certifications A USRC Verified Rating can be used for promotional, marketing and publicity purposes. Owners whose Verified Ratings meet specific performance thresholds can use the badges above to promote the resilient design of their buildings. Each Verified Rating is: awarded one to five stars in each dimension.

Strong shaking—Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built structures. SDC/Map Color. D/Light Brown.Early earthquake warning systems typically use seismometers to detect incoming fast P-waves. When shaking is felt, a signal is sent to the local seismic authority, which rapidly sends out an alert to those in the region who are likely to feel shaking, hopefully before the more damaging S-waves arrive.Although numerousintensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes, the one currently used in the United States is the Modified Mercalli (MM) Intensity Scale. It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann.
