Some data challenges in Earthquake Seismology
Earthquake Monitoring since around 1895
International data exchange and standards established early on.
Seismological data analysis since around 1950
Signal processing, tomography, ambient noise imaging, …
Advanced computer analysis early on.
Data challenges on the observational side:
Gathering – monitoring, transfer, storage,
Analysis – real-time, information processing,
Quality – metadata, Quality Control, formatting standards,
Access – archival and distribution,
Data challenges on the modelling side:
Wave propagation through complex media
Rupture process modelling in inhomogeneous media
More recent data challenges
in Earthquake Seismology
Matching modelling and observation
Waveform inversion
(large amounts of data and computational resources)
Rapid (near-real-time) data analysis
Rapid earthquake warning (seconds)
Tsunami warning (seconds to hours)
Rapid earthquake information (seconds to hours)
Broad data access and availability (educational and scientific)
Data provenance, quality,
Integrated visualisation and computing facilities
Data management, exchange,
Distributed resources
Combining data archives, computational resources,
shared analysis tools
Monitoring infrastructure: seismological networks
