As an international centre with focus on tsunamis, the ITIC has for many years worked with tsunami and seismological organizations around the world to heighten awareness in order to encourage the building of better technical warning systems, and a better prepared public.  Towards these ends, the ITIC has established working relationships with the following international science organizations:

  • WDC-SEG-TSUNAMIS / NGDC – for the collection and archiving of significant tsunami events and building of a global, high-quality, referenced database, including both runups, wave and earthquake observations, and also sea level mareograms. 

  • IUGG-Tsunami Commission – for the encouragement of tsunami research, organization of post-tsunami international tsunami surveys to collect perishable data to improve hydrodynamic models and develop tsunami-resistant engineering guidelines, co-sponsorship of tsunami workshops to highlight issue of common priority and also to bring tsunami science to countries through pre-ICG/PTWS workshops.  ITIC and NGDC work together with IUGG-TC.

  • US Geological Survey  / IRIS Global Seismic Network (GSN) / Federation of Digital Broadband Seismographic Networks (FDSN) – for the cooperation to install and support real-time continuous waveform data streams that are essential for tsunami warning monitoring.  Installation of high-quality, broadband stations (STS-1, or STS-2 or equivalent), and free and open data sharing are essential for issuing timely warnings since seismic waves travel more than 40 times faster than tsunami waves.  The USGS provides both earthquake monitoring on 7x24 basis, and also provides infrastructure through which the GSN data is made available.  The FDSN is the overarching international coordination organization to which the ITIC hopes every country contributing to seismic monitoring will join.

  • University of Hawaii Sea Level Center (UHSLC) / IOC Global Sea Level Observing System Group of Experts Chair (GLOSS GE) – as a resource supporting and installing sea level stations in the IOTWS since 2005, for the continued efforts over that last decades with the Pacific through numerous programmes, and as a resource for IOTWS and PTWS Sea Level Working Groups for data collection platforms and station configurations, transmission arrangements and standards, and data archiving of GLOSS stations.
