NGAW2 R Documentation
Database from NGA-West2 Flatfile
Description
A dataset containing 21540 recordings from NGA-West2 Flatfile, which is a reference for metadata.
It helps to link stations and earthquakes, obtain usable frequencies and real azimuth degree of
the sensor.
Usage
NGAW2
Format
A data frame with 21540 rows and 12 variables
- Record.Sequence.Number
record sequence number, identifies a specfic recording
- EQID
earthquake ID, identifies a specific earthquake event
- LP.H1..Hz.
low pass corner frequency of the frist horizontal component of ground motions
- LP.H2..Hz.
low pass corner frequency of the second horizontal component of ground motions
- Factor
the ratio for usbale frequency from corner frequency
- Lowest.Usable.Freq...H1..Hz.
lowest usable frequency of the frist horizontal component of ground motions
- Lowest.Usable.Freq...H2..H2.
lowest usable frequency of the second horizontal component of ground motions
- Lowest.Usable.Freq...Ave..Component..Hz.
the average of lowest usable frequency of two horizontal components
- File.Name..Horizontal.1.
the file name for the first horziontal component of ground motion in NGA-West2 database
- File.Name..Horizontal.2.
the file name for the second horziontal component of ground motion in NGA-West2 database
- H1.azimth..degrees.
the azimuth degree of the first horizontal component of ground motion
- H2.azimth..degrees.
the azimuth degree of the second horizontal component of ground motion
