1. Center for Engineering Strong Motion Data (CESMD) Update March 25, 2013 CISN Advisory & Steering Committees Meeting

2. March 25, 2013  Established as part of CISN in 2006 as joint effort of US Geological Survey and California Geological Survey  Collect, archive, and disseminate records of ground and structural responses to earthquake strong motions of engineering interest  Internet Quick Reports (IQR) of strong motion data within minutes for rapid response to earthquakes  Provide information about station, site, geology, etc.  Provide online search access to CESMD archive principally for US data; also called Engineering Data Center (EDC)  Provide integrated search and virtual access to global strong- motion records through the Virtual Data Center (VDC) CESMD Objectives and Operation CISN Advisory & Steering Committees Meeting

3. March 25, 2013 Two Components of CESMD CISN Advisory & Steering Committees Meeting

4. Automated Import of Records to IQR Task: Records from CISN and other networks, each with a variety of instrument types  Provide a coherent presentation of strong motion records, with Quality Assurance Full records, ShakeMap uses peak values Automated processing and import of CISN strong-motion records March 25, 2013 CISN Advisory & Steering Committees Meeting

5. March 25, 2013 CESMD Internet Quick Report (IQR) for US Data For earthquakes in CISN region, records are available via IQR automatically within minutes after M>3.5 earthquakes, records w/ PGA>0.5%g 78 automatically generated IQR in 2012 CISN Advisory & Steering Committees Meeting

6. Small records (M 3.5 with PGA<0.005g) FTP(ftp://140.174.65.75/Small_Record_and_Earthquakes) Users can access this ftp site through the link named “Small Records FTP” in the EDC search page Records from 128 earthquakes in 2012 in FTP March 25, 2013 Small Records Served via FTP CISN Advisory & Steering Committees Meeting

7. New Face of the Strong-Motion Virtual Data Center (VDC) VDC has been incorporated into CESMD (originally developed at UCSB) Metadata upload process now uses standard format, is more automated VDC has been updated with the addition of M≥5.0 US and New Zealand records since 2007 COSMOS promotes international SM networks making data available to VDC, development of global metadata standards March 25, 2013 CISN Advisory & Steering Committees Meeting

8. March 25, 2013 CISN Advisory & Steering Committees Meeting

9. March 25, 2013 Japan K-NET and KiK-net records now in VDC CISN Advisory & Steering Committees Meeting

10. VDC Projects in Progress Software completed to convert Japanese K-NET and KiK-net data for uploading record metadata; uploading to VDC now underway (records from 24 earthquakes already uploaded) – Criteria: M>5, at least 1 comp > 10%g, depth<100 km – Only M9 strong motion records that exist Collaborating with ITACA (Italian Accelerometric Archive) to finalize conversion of ITACA records to COSMOS format Interacting with other strong-motion networks internationally to develop protocols for serving their data through the VDC Partnering with COSMOS to develop new tools for VDC, establish standards for data and metadata quality control March 25, 2013 CISN Advisory & Steering Committees Meeting

11. Records from 296 earthquakes with M=>4.0 in CESMD March 25, 2013 CESMD Archive No. of Earthquakes vs Magnitude CISN Advisory & Steering Committees Meeting

12. About 9270 station records from earthquakes with M=>4.0 in CESMD March 25, 2013 CESMD Archive No. of Records vs Magnitude CISN Advisory & Steering Committees Meeting

13. CESMD Summary Provides access to strong-motion data of engineering interest from CISN, the US and other seismically active countries The Strong-Motion Virtual Data Center (VDC) is operational again; US and New Zealand data for M ≥ 5 since 2007 have been loaded Currently updating VDC to include Japan K-NET and KiK-net data (close to completion) Ground and some structural strong-motion data are processed and posted from CISN and other networks to aid in response to earthquakes and to guide future seismic design improvements March 25, 2013 CISN Advisory & Steering Committees Meeting
