Early-est
Coordination of all real time seismic networks in Greece by NOA-IG is currently comprising of more than 145 broadband seismic stations available in real time.
Networks operated by NOA
A developing accelerometric network comprising of over 150 stations, 80 of which are available in real time (yellow). The upgrade of the current seismic network with the co-located deployment of accelerographs is in development.
Networks operated by NOA
A GPS network of 20 continuous stations with data to rapidly detect uplift and subsidence is expansion combining existing CGPS stations operating off line for research purposes real time operation and link to the HL-NTWC.
Networks operated by NOA
A tide-gauge network of 12 stations is already available in real time to NOA-HLNTWC.
Networks operated by NOA
Three tide gauge stations have been installed in June 2013 in Koroni, Kihtira, Paleochora and are operated in cooperation with JRC. Data from those stations are available to NOA-HLNTWC and JRC in real time. Each station is consists of two sensors, one pressure and one microwave sensor (radar) and a CGPS.
Four tide gauge stations, with microwave sensors, have been installed, in 2013, in Santorini and Corfu Islands and in 2014 in Rhodes Island and Thessaloniki, with data transmitted to NOA-HLNTWC in real time.
Networks operated by NOA
Five out of 21 tide gauge stations of the Hellenic Navy Hydrographic Service are already available in real time to NOA-HLNTWC via ftp communication procedure.

In the framework of cooperation with JRC, both MOD1 & 2 scenario databases have been fully installed and are already in use. The set of scenarios enables NOA-HLNTWC to estimate wave arrival times and wave heights near the coast. The processing and analysis of the scenarios has been implemented using the Tsunami Analysis Tool.
Tsunami Analysis
Moreover, Tsunami Travel Times software (TTT) by Geoware (kindly provided by NOAA) has also been locally installed and the operator has the possibility to estimate the tsunami arrival time either by using the scenario’s travel time or those calculated by TTT
Tsunami Analysis
A scripting module has been developed in house following Tsunami Analysis Tool messaging output. This module gives to the user the opportunity to send simultaneously all three types of messages, i.e. e-mail, fax and GTS, the last through the Hellenic National Meteorological Service (HNMS) via the dedicated VPN link between HNMS and NOA HL-NTWC operating centers. The SMS technology has also been used during the last exercise (NEAMWAVE14) and the extended Communication Tests.
Message dissemination
Training of the duty officers involved in the 24/7 operation of the HL-NTWC is carried on constantly, since the operators are taking shifts.

Talks and presentations: o The operating procedures of a TSP
o Earthquake and tsunami hazards
o Sea-level measurements
o Operation of dedicated software (TAT, TTT, Seiscomp3 etc)

NOA-HLNTWC participates in the GTIMS project, coordinated by JRC. The aim of the project is to issue pseudo-messages and create Tsunami Analysis Reports for every potential Tsunami event occurring worldwide caused by earthquakes of magnitude equal or greater than 7.0 for a period of 1 year.
Applied to also participate in the second phase of the project – GTIMS2.
NOA-HLNTWC successfully participated in the NEAMWAVE12 exercise that was held in November 2012, providing a pre-computed tsunami scenario.
