Charge
•
Define an evolutionary path for transforming
existing elements of ANSS into a functional
nationwide system—with emphasis on steps that
can be taken in the near term (1-3 yrs), based on
realistic ANSS funding projections
•
Clarify key system performance goals [relevant to
system design] and characterize “where we are
now”
•
Account for geopolitical realities as well as
abstract ideals in designing an ANSS system
architecture
Some Key Issues

ANSS not fully funded; OFR02-92
vision unrealistic

Status quo unacceptable — patchwork,
not a system

New vision needed with evolutionary
steps
Some Guiding Principles

Adoption of guidance from NIST’s Baldrige National Quality
Program — a systems approach to Performance Excellence

Desired Outcome — effective system with standardized
products; operated with a high degree of professionalism by
dedicated well-trained staff

EQ reporting depends on a three-legged stool of (1) sensors,
(2) processing, and (3) scientific knowledge; ANSS
architecture must explicitly address these elements

Program — 7 Criteria

Planning tools)

Road Map for Partnership
How do we reconcile state/local ownership,
investment in, and ongoing support of
significant infrastructure for seismic
monitoring with the prescriptions of ANSS
decision makers?
What we’ve done to date

Clarified key system performance goals

Characterized “where we are now”

Canvassed views on “centralization”

Developed consensus on system
architecture

Explored evolutionary steps
Some problems with status quo
Standardization of algorithms lacking
 Need for reconciliation of multiple
reports of earthquakes
 No centralized waveform archiving
 No standardized error estimates
 Inadequate metadata
 Uneven exchange of waveform data
between networks

Problems (continued)
No on-site 7X24 response
 Limited access to data by research
community in RT
 Software and system complexity is
daunting
 Code not “open source”
 Duplication of software development
 RSN’s located in high seismic areas

So, what’s different?
• ≥ 7 RPCs
• NEIC is

• RPCs

Features of an
Integrated Processing Service

Standardized product algorithms
 Facilitates more rapid and cost-effective
response because of dedicated 7X24
 All products go into a central DBMS
 Continuous waveform archive
 Distribution of concentrated RT waveforms to
R&D groups
 Single connection for Earthscope USArray and
PBO data streams
 All ANSS partners have access to this DBMS
 Regional networks backup IPS
WG-E Recommendations

IPS concept
 Undertake evolutionary steps
– Do an evaluation – is this realistic? how
expensive? Identify unproven technologies
– Write system specifications for standardized
processing
– Undertake a pilot project; do no harm
– Connect regions
– Parallel operation, evaluation, and testing
– Distribute standardized software to RSNs
Recommendations continued

Develop ANSS commitment to transparent
process for software development
 Identify and pursue joint funding of software
development to enable USArray/PBO/ANSS
waveform integration
 Develop a good process for ANSS development
(framework, best practices, principles, feedback)
based on Baldrige approach
 Identify dedicated manager and provide budget
(~$300K/yr) for software development
