What is NGA database?
The NGA-East database constitutes the largest database of processed recorded ground motions in Stable Continental Regions (SRCs). It was developed as part of a large multi-disciplinary research project coordinated by PEER. … The database contains over 29,000 records from 81 earthquake events and 1379 recording stations.
What is a recording of ground motion?
Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. … The first seismograph was developed in 1890.
What is El Centro ground motion?
The earthquake was characterized as a typical moderate-sized destructive event with a complex energy release signature. … It was the strongest recorded earthquake to hit the Imperial Valley, and caused widespread damage to irrigation systems and led to the deaths of nine people.
What are ground motion parameters?
The three ground motion parameters i.e. peak ground acceleration (PGA) value, response spectrum and acceleration time history of a site, commonly used in the design of structure, are known as design basis ground motion parameters (DBGM).
What is strong motion data?
Strong Motion Data Portals The Rapid Raw Strong Motion (RRSM) is an entirely automated system that uses open data from EIDA. It provides earthquake information and strong motion parameters including PGA and PGV within minutes of any event.
