What did Arturo Arias invent?
Arturo Arias was a Chilean inventor, in 1969 that saw the need of inventing a device to measure the tremors that appear every other day in Chile. This engineer created a parameter that is used to determine the seismic risk of an area, called “Instrumental Seismic Intensity” or “Arias Intensity” (AI).
How do you create a response spectrum for earthquakes?
A response spectrum is used to provide the most descriptive representation of the influence of a given earthquake on a structure or machine. It is similar to a vehicle moving on the ground. In both cases there is relative movement between the vibrating system (structures or machines) and the ground.
Where does the NGA-east database come from?
It was developed as part of a large multi-disciplinary research project coordinated by PEER. The NGA-East database includes the two- and three-component ground-motion recordings from numerous selected events (M > 2.5, distances up to 1500 km) recorded in the Central and Eastern North America (CENA) region since 1988.
Which is the most comprehensive ground motion database?
The NGA-West2 ground motion database includes a very large set of ground motions recorded in worldwide shallow crustal earthquakes in active tectonic regimes. The database has one of the most comprehensive sets of meta-data, including different distance measure, various site characterizations, earthquake source data, etc.
Which is the current version of peer Nga?
The PEER NGA databases, flatfiles, and reports are released in their current version “as is.”
Is the peer ground motion database based on peer reports?
The PEER NGA online ground motion database is based on the contributions of a significant number of PEER researchers, including junior and senior researchers, post-doctoral fellows, graduate and undergraduate students, and practicing earthquake engineers and scientists. The following PEER report formed the basis for this tool:
