FUTURE PLANS
(2005-2010)
Avi Shapira
ISC's EC &GC meeting - 2005
ISC ROLE
1. ISC – A data centre
a) Maintain and upgrade hardware and software for data collection, event
grouping, phase association and data dissemination.
b) Be a depository for seismological information other than waveform data.
c) Provide data and information that the seismological community may
need.
2. ISC – An Analysis Centre
a) Maintain and upgrade hardware and software for editing the ISC
Bulletin and Catalogues.
b) Develop new analytical tools and implement new methods and algorithms
to improve the analysis and increase accuracy.
3. Help set up standards

ISC current Operation
To be continued during 2005-2010
1. COLLECTION of parametric earthquake information
and phase data.
2. Automated and manual ANALYSIS and REVIEW of
hypocentres and phase readings and association of other
seismological information (e.g. links to waveform data,
macro-seismic information).
3. DISTRIBUTION of the results in an ISC Bulletin and
Catalogues. (Web, FTP, CDs and Prints).
ISC's EC &GC meeting - 2005
Other Services Recently introduced on ISC webpage
To be continued during 2005-2010
• Maintenance of the Seismic Stations International
Registry.
• Update and distribution of seismic station information
(Stations book).
• Publication of ISC documentation (formats, software,
reports)
• Bibliography of Seismology (1956-1995).
• SKS splitting parameters from special projects.
• Links to Seismologists and Seismological Institutions.
• Links to Real Time seismological information.
ISC's EC &GC meeting - 2005
Adopt and Implement IASPEI’s
recommendations
• Nomenclature of Seismic Phases (implemented in 2003).
• Regionalization of Seismic Epicentres (implemented in
2004).
• Magnitude determinations (under discussions)
• Seismic stations code names (under discussions)
• Location procedures and TT models (initiated).
ISC's EC &GC meeting - 2005
Improving Computer Facilities
Possibly during 2005-2006
•Replacement of old computers.
•Change to a BB internet provider.
•Move to LINUX operating systems.
•Upgrade backup capabilities.

Very old
ISC's EC &GC meeting - 2005
ISC website
Restructure its existing content (almost completed during 2005)
Improve appearance and user interface.
Integrate new services:
Seismological Bibliography (Local/Regional publications).
Volcanic Eruptions (under discussion with IAVCEI ).
Macroseismic information.
Registration of Reference Events (with IASPEI’s WG)
ISC's EC &GC meeting - 2005
IMPROVE ISC LOCATIONS
ISC must modernize its location algorithms, methods and travel time models which
remain unchanged for more than 30 years.
- ISC locations are used as reference by many researchers in many countries.
- ISCloc facilitate relatively easy accommodation of new procedures and TT
models.
- ISC will follow IASPEI recommendations if and when formulated.
ISC's EC &GC meeting - 2005
MODERNIZE SEISMIC STATION
CODE NAMES
The coding system in the International Station registry does not meet all current
requirements by the parametric data centres (ISC, NEIC, EMSC) and by data
contributors.
- IASPEI established a special working group to come up with recommendations.
- ISC will follow IASPEI recommendations, if and when formulated .
- Any recommended new system will require changes to almost all ISC s/w.
ISC's EC &GC meeting - 2005
MODERNIZE AND AUTOMATE
MAGNITUDE DETERMINATIONS
•ISC will adhere to the recommendations of IASPEI’s sub-commission
and ask its data contributors to follow the formulated instructions what
should be measured.
•ISC will promote the use of Mw as a reference magnitude scale.
•ISC will develop a program autoSEM that will automatically search for
Seismic Moment information and provide ISC Mw magnitudes.
•autoSEM will be able to automatically retrieve waveform data from
selected stations and apply already developed procedures to determine
Mo, Mw, mb and Ms.

MODERNIZE AND IMPROVE
INTERACTIVE ANALYSIS
ISC has to start planning for the next generation of analysis tools. Also
required are additional aid tools for the routine analysis.
- Support the initiative of Prof. Woodhouse to use for developing an
interactive analysis tool.
-Collaborate with a seismological institution (e.g. GII) that will be
willing to help modify its interactive processing program to serve as a
development platform for testing the applicability and practicalities of
various concepts and ideas.
ISC's EC &GC meeting - 2005
Database of Reference Seismic Events
Cooperating with the Working Group on Reference Events of the IASPEI Commission
on seismological Observations and Interpretation (Co-chaired by Bob Engdahl and
Paul Richards)
Total proposed costs ~ US$ 270,000 for 3 years.
Approach seismological centres to collect seismic events that qualify by having
locations known to 5 km or better.
Definition of qualification criteria, review and validation of the nominated events will
be made by members of the WG.
ISC will collect the information via the internet, prepare it for review and validation
and associate all available information with the selected events.
ISC will disseminate the information and make it available to the seismological
community.
