Issue: Aggregating
Current Situation:
- Web site A: fault information
- Web site B: electromagnetic observations
- Web site C: hydro and gas measurements
- Web sites D, E, F: earthquakes data from various networks
- Web services G, H, I ... : map, source, propagation, acceleration, site
response, etc. services
- Web sites X, Y, Z ... : gov't emergency authorities
- Want to aggregate data to (for R&D or realtime alerts):
- compare network locations and compute new ones
- examine correlations of geophysical observations
- interface with authorities re: events and risks
Issues:
- Different databases, attributes, locations, services
- Can do now by building specialized systems
- Neither flexible nor extensible
