Epicentral distances of database records

[amrutj]

Dear Sir,

Could you please assist me in finding epicentral distances of the earthquakes that are given in Seismo Spect database...

ChiChi.dat

Friuli.dat

Hollister.dat

Imperial_Valley.dat

Kobe.dat

Kocaeli.dat

Landers.dat

Loma_Prieta.dat

Northridge.dat

Trinidad.dat

Thanks and regards

Generally speaking, I think it is advisable to obtain ground motion records for research and practice from international organizations which have thorough processing procedures for baseline adjustment, filtering, and metadata preparation. Examples include the European Strong Motion Database, COSMOS, PEER, the Italian Accelerometric Archive, etc. Nonetheless, I have previously compiled this data based on information in the headers in the samples in SeismoSpect and the table below gives the data for those records.

Event Mw Station EpiD HypD Rjb VS30 Site Class

Chi-Chi 7.62 TCU045 77.50 77.91 26.00 705 C
Fruili 6.50 TOLMEZZO 20.24 20.87 14.97 505 C
Hollister 5.60 USGS1028 20.61 21.90 19.55 199 D
Imp Vall 6.53 USGS5115 30.77 32.34 13.31 189 D
Kobe 6.90 KAKOGAWA 24.20 30.10 22.50 312 D
Kocaeli 7.51 YARIMCA 19.30 25.07 1.38 297 D
Landers 7.28 STA24 44.02 44.58 2.19 1369 B
Loma Prieta 6.93 STA47381 31.40 35.94 12.23 350 D
Northridge 6.69 STA24278 40.68 44.29 20.11 450 C
Trinidad 7.20 STA1498 76.75 78.22 312 C

Mw is moment magnitude
EpiD is epicentral distance in kilometers
HypD is hypocentral distance in kilometers
Rjb is the Joyner-Bore distance in kilometers
VS30 is the shear wave velocity in the upper 30 meters at the recording station, m/s
Site Class is the NEHRP Site Class

Thanks a lot

[Kamrack]

can someone help with information on component for creating and adding required number of records without the BDE in Ddelphi 4? freeware or shareware.

What exactly do you mean Kamrack? Which is the operation that asks you for the BDE?
