Taiwan Ground Motion Model (TGMM) and Database

Taiwan Ground Motion Model and Ground-Motion Database

Update note

SSHAC_GM_V9_20180620

  • update 2006 Pingtung earthquake Ztor and path (EQSN =239, 240)

SSHAC_GM_V8_20180120

  • update event classification to event_classification_20170206
  • update distance calculation (sgm.for.Person_20171228.RDS, CCLD20180105/p4cf.out) (from Brian).
  • update Rmax estimation (Rmax_c_TNGA_Adjusted_2018_01_16_for_Person.RDS) (from Brian).
  • update station information from Dr. Kuo (NCREE) for STA_ID=MTN119.
  • #22 remove two records without NS component time history.
  • #23 remove record with spike on time history.
  • remove duplicated records (34) with same station ID.
  • remove EQID=1(1981_0129_0451_36), STA_ID=SMART1-M11 with SA value = -999.

SSHAC_GM_V7_20170919

  • #21 Update the Vs30 of MTN stations in Chi-Chi event. (9 records)

SSHAC_GM_V7_20170918

  • Fix #20 EQ: 1995_0223_0519_03 (Pfile:02230518.P95) (EQSN:038) only have 21 records

SSHAC_GM_V7_20170802

  • Fault rupture models for the two new events occurred in 2016 (the Meinong event, Category A, and the deep intra-slab event, Category B)
  • 21 new finite fault models obtained by Dr. Lee of IES.
  • Subduction earthquake source scaling relations recommended by the PEER NGA-Sub project. This update does not affect Category A events or crustal events.
  • Path data for new entries for the two 2016 events and updated fault rupture models.
  • Path data for BATS subduction zone records.
  • add ChiChi recordings (recorded by IES’s MTN network).

  • add column within30 for the flag of earthquake within 30km buffer zone.

SSHAC_GM_V4_20170120

  • add column "eq.type.crust" for "eq.type" = "shallow crustal" or "deep crustal"

SSHAC_GM_V4_20170117a

  • fixed the duplication of site database with STA_ID=TAP105. (previous flatfile will have two Vs30 and Z1.0 values of TAP105 station)

SSHAC_GM_V4_20170117

  • update earthquake flag column from NCREE to version 20171113.

SSHAC_GM_V4_20170111

  • add earthquake flag column from NCREE.
  • add Mw_source column.
