6. None Minimum “Complete” Earthquake Catalog/Station Log Options… Advantages… Good science practice Record of station information Archive of event data

7. Earthquake Catalog/Station Log Information… Station Log… Earthquake Catalog… Record “state of health” information for your seismograph Note dates and times of calibrations, change of location, new software, time synchronization, noise characteristics, earthquakes recorded Record earthquake information for all (well recorded) seismograms – event origin time, location, magnitude, epicenter-to-station distance, etc.

8. Examples… Station log… (hand written notes) Date and Time (GMT) Comment 2006 9/1 16:25 AS-1 set up and operating, clock synch. 2006 9/4 ~10:14 EQ from Japan 2006 9/16 ~04:45 EQ M6.5 Gulf of CA 2006 9/18 20:52 Calibration pulse recorded 2006 9/20 12:25 Install new version of AmaSeis 2006 9/22 09:03 EQ M7.2 Sumatra (good surf. waves) 2006 9/28 20:33 Restart computer, clock synch. 2006 9/20 ~07:42 EQ Rat Islands, Aleutians... 2007 5/27 10:51 Turn off AS-1 and computer for summer

9. Earthquake Catalog (Excel File)… http://web.ics.purdue.edu/~braile/edumod/as1lessons/InterpSeis/EqList.xls Revised to YYMMDD Format

10. Suggestions… Record at least minimum information, hand written Focus on well-recorded events (don’t worry about every “wiggle” or weak, distant EQs – unless you just want to see where it came from) Synchronize clock every few days or use Internet time synch. Get an “Atomic Clock”, set to GMT time Create a seismogram archive for your station Send you best seismograms to SpiNet and download some seismograms for comparison
