Sir/Madam,
Preliminary Seismological Analysis
Enclosed please find the preliminary seismological analysis from July to
September 2011 for the station HKPS. Please note that following the
decommissioning of our long-period seismograph on 31 May 2011, the following
changes have been made to our analysis results:
1. Analyses previously performed with records from the long-period seismograph
accommodated in the cellar of the Observatory are now performed with records
from Hong Kong Po Shan (HKPS) seismograph station located in Mid-Levels on
Hong Kong Island.
2. Prefixes i- and e- are no longer marked to phases.
3. Broadband records include all 3 components.
The analyses for Apr – June 2011 will follow shortly. For enquiries, please
contact Mr W C Woo at +852 29268433 or wcwoo@hko.gov.hk.
Yours faithfully,
(Mr. D.S. Lau)
for Director of the Hong Kong Observatory
