A core-team of ATOS (project co-ordinator) and GFZ (technical co-ordinator) perpared the installation with a great support of local staff. On Tuesday, October 11, the offical handover took place.&nbsp;DEWS has been installed for evaluation and testing purposes in a closed and secure test environment, within the domain of Tsunami Crisis Centre and is solely used by its technical personnel. The deployed version of system corresponds to the DEWS National Centre (NC) version, being possible in the future to deploy the DEWS Wide Area Centre (WAC) version for international communication with other DEWS National Centres.</p> <p> <a href=";groupId=10156&amp;t=1319118940439"><img alt="" src=";groupId=10156&amp;t=1319119138111" style="width: 700px; height: 409px;" /></a></p> <p> <span style="font-size:9px;"><strong>Drs.

The units are addressable with geocodes that provide a bijective mapping between territories and unique identification codes. Early warning systems for natural or man-made hazards often map affected or threatened areas to administrative units to establish a spatial reference that is comprehensible to all parts of the population. Addressing these territories in an international context has several requirements, such as worldwide coverage, completeness and topicality, which must be met by geocode standards. In this paper, the practicability and suitability of international geocode standards are examined in the context of the requirements of large-scale early warning systems. This paper exposes the insufficiencies and limitations of existing geocode standards International Organization for Standardization (ISO)-3166, Second Administrative Level Boundaries data set project (SALB) and Nomenclature of the Territorial Units for Statistics (NUTS) and emphasises the suitability of the non-official hierarchical administrative subdivision codes (HASC). The analysis is framed in the context of addressing affected areas for an Indian Ocean tsunami early warning system. This system was developed within the Distant Early Warning Systems project according to the requirements of the United Nations Educational, Scientific and Cultural Organization (UNESCO) Intergovernmental Oceanic Commission for Regional Tsunami Watch Providers (RTWPs).</div> Matthias Lendholt 2011-06-09T14:35:20Z New book publication "Geoinformatics" with a reference to DEWS Matthias Lendholt 2011-05-31T09:33:56Z 2011-05-31T09:11:10Z <p> The new book <a href=""><span id="btAsinTitle" style="">Geoinformatics: Cyberinfrastructure for the Solid Earth Sciences</span></a><span style=""> will be published on 30th June.

EU support for the research came from the DEWS ('Distant early warning system') project, which received just over EUR 4 million from the 'Information society technologies' (IST) Thematic area of the EU's Sixth Framework Programme (FP6) to develop an advanced interoperable tsunami early warning system for strong early warning capacities.</p> <p> When a 1,600-kilometre (km) segment of the Indian tectonic plate jolted downward off the coast of Indonesia 6 years ago, it provoked the second strongest earthquake ever measured (a magnitude of 9.2) and tsunami waves 30 metres high. The resulting devastation brought home the urgent need for a system to give populations at risk from a tsunami as much warning as possible.</p> <p> Germany was the first to take action with a joint German-Indonesian tsunami detection and warning system (GITEWS). The EU decided to take this innovation further by funding and launching DEWS in 2007 to provide protection to all Indian Ocean nations.</p> <p> 'It's almost impossible to give numbers, but if DEWS had been in place in December 2004 a very large number of lives could have been saved,' said Andreas Küppers of the Helmholtz-Zentrum Potsdam, German Research Centre for Geosciences (GFZ), the researcher in charge of DEWS.</p> <p> The project is now being used to detect and analyse seismic events in the Indian Ocean, quickly assess their potential to unleash a tsunami, and warn at-risk countries through a network of detectors including broadband seismometers, land and ocean-surface based GPS instruments, tide gauges, and ocean bottom pressure control devices.</p> <p> The data generated by these instruments is streamed via communication satellites to a central station in Jakarta, Indonesia for processing. SeisComP3 software, developed by the GFZ, rapidly determines the magnitude and location of a seismic event.</p> <p> 'The former systems needed 11 or 12 minutes to detect a signal and locate the source,' said Professor Küppers. 'The same can now be done in four minutes.'</p> <p> Once the system detects an earthquake powerful enough to create a tsunami, it begins to analyse and model the risk of a tsunami. However, even with powerful computing capabilities, it would take too long to model a tsunami in real time. So DEWS researchers use libraries of temblors of different magnitudes and source locations, coupled with detailed simulations of the waves they would create along the Indian Ocean coastline, to determine which areas are at risk.</p> <p> In addition to this time challenge, the DEWS team has also had to cope with the difficulties of having to warn 20 countries in a multitude of languages, many of whom do not see eye-to-eye politically. 'It is a multilingual system that can distribute different messages to different people in different languages,' Professor Küppers pointed out. 'It was even more difficult politically to get all the players together at one table, but we are well on our way to overcoming those problems as well.'</p> <p> Researchers are now turning their attention to Europe and countries there at risk from tsunamis, namely those bordering the Mediterranean and the northeast Atlantic. They are even advocating the development of a new profession - that of the 'early warning engineer' - to offer maximum protection to vulnerable communities.</p> <p> 'If you want to tackle these problems properly, you have to take the time and effort to involve everybody,' said Professor Küppers. 'So we'd like to see people acquiring a new full-scale profession and be able to take care of the whole early warning field.'</p> <p> <a href=";ACTION=D&amp;SESSION=&amp;RCN=32224" target="_blank">&gt;&gt; Press release at CORDIS </a></p> Antje Treutler 2011-03-22T16:35:12Z Presentation at 76th OGC TC Meeting: "Usage of OASIS standards Common Alerting Protocol (CAP) and EDXL-DE in DEWS" Antje Treutler 2011-03-29T10:48:14Z 2011-03-22T16:43:26Z <p> The usage of OASIS standards CAP and EDXL-DE in DEWS were prestented to the Early Warning and Disaster Management (EDM) Domain Working Group (DWG) at the 76th OGC Technical Committee Meeting in Bonn, Germany.</p> <p> <img alt="ogc" height="65" src=";t=1301054230331" width="160" /><span class="moz-txt-link-freetext">&nbsp; </span><a class="moz-txt-link-freetext" href="" target="_blank"></a></p> <p>  </p> <p> <img alt="edxl-thumb" height="149" src=";t=1301054230356" width="198" />&nbsp;&nbsp; <img src=";groupId=10156&amp;t=1301064531952" style="width: 16px; height: 16px;" /><a href="" target="_blank">&nbsp;download presentation</a></p> Antje Treutler 2011-03-22T16:43:26Z Publication: "Tailoring spatial reference in early warning systems to administrative units" Antje Treutler 2011-03-29T10:43:36Z 2011-03-22T16:51:56Z <p> "Tailoring spatial reference in early warning systems to administrative units", Earth Science Informatics, Volume 4, Issue 1, 7-16</p> <p> <img alt="cover" height="126" src=";t=1301054230364" width="95" /></p> <p> DOI: 10.1007/s12145-010-0075-y</p> <p> <a class="moz-txt-link-freetext" href=""></a></p> <p> Abstract:</p> <p style="margin-left: 40px;"> This paper presents a novel approach for early warning systems to transform the spatial reference of dispersion models into addressable administrative units, enabling an intelligible warning message reception and spatial awareness. The spatial reference along the entire information chain from sensor measurements via dispersion model to warning dissemination is discussed. The core concept behind this approach is the application of the Egenhofer-Model for analysis of binary topologic relations. It is used to identify topologic relations between dispersion model forecasts and administrative units. The result set of intersection matrices defines the relations that are counted for area classification with hazard specific parameters. The design of a generic and hazard-independent web service based on Open Geospatial Consortium (OGC) standards is presented in combination with results of the reference implementation.</p> Antje Treutler 2011-03-22T16:51:56Z Presentation at deegree day: "Application of OGC Web Processing Service (WPS) in Tsunami Early Warning System DEWS" Antje Treutler 2011-03-29T10:49:44Z 2011-03-22T16:55:03Z <p> "Application of OGC Web Processing Service (WPS) in Tsunami Early Warning System DEWS" , deegree day, University of Bonn, Germany</p> <p> <img alt="degreeday" height="32" src=";t=1301054230373" width="202" /></p> <p> <a class="moz-txt-link-freetext" href=""></a></p> <p>  </p> <p> Erfahrungsbericht: WPS-Nutzung in einem Tsunami-Frühwarnsystem</p> <p> <img alt="degreeday-thumb" height="148" src=";t=1301054230314" width="198" /></p> <p>  </p> <p> <img src=";groupId=10156&amp;t=1301064531952" style="width: 16px; height: 16px;" /> <a href="" target="_blank">Download presentation [in German]</a></p> Antje Treutler 2011-03-22T16:55:03Z Presentations at AGIT 2010 Conference in Salzburg, Austria Antje Treutler 2011-03-29T10:53:38Z 2011-03-22T16:56:49Z <p> Two posters and one technical paper contributed to the AGIT (Angewandte Geoinformatik) Conference (all in German).</p> Antje Treutler 2011-03-22T16:56:49Z Press release at ICT results: "New tsunami early warning system stands guard" Antje Treutler 2011-03-28T11:57:49Z 2011-03-22T17:01:04Z <p> <img alt="" src=";groupId=10156&amp;t=1301313198745" style="float: left; width: 225px; height: 193px; " />The 2004 Boxing Day tsunami killed 230,000 people. The next time a tsunami threatens Indian Ocean nations, a lifesaving early warning system spearheaded by the EU will be in place.</p> <p align="justify"> Starting a few seconds before 1am universal time on 26 December, 2004, a 1600km segment of the Indian tectonic plate jolted downward just off the coast of Indonesia, lifting the seafloor by several metres and displacing some 30 cubic kilometres of water. With a magnitude of 9.2, it was the second strongest earthquake ever measured. The resulting tsunami waves - some of them 30m high - began to hit just 20 minutes later. They wreaked massive destruction and killed an estimated 230,000 people in Indonesia, Sri Lanka and 12 other countries.</p> <p align="justify"> This disaster, one of the deadliest in recorded history, brought home the urgent need for an effective system to give at-risk populations around the Indian Ocean as much warning as possible the next time a tsunami strikes.</p> <p align="justify"> Europe quickly rose to the challenge. Germany was the first to take action with the joint German-Indonesian tsunami detection and warning system called GITEWS.</p> <p align="justify"> Building on the infrastructure and experience developed through GITEWS, the EU funded and launched DEWS (Distant Early Warning System) in 2007 to include and provide protection to all the nations of the Indian Ocean region.</p> <p align="justify"> DEWS has now created and started to deploy a sustainable system to detect and analyse seismic events in the Indian Ocean, quickly assess their potential to unleash a tsunami, and warn all of the at-risk countries in time to save lives.</p> <p align="justify"> "It's almost impossible to give numbers," says Andreas Küppers, researcher in charge of the DEWS demonstrator, "but if DEWS had been in place in December, 2004, a very large number of lives could have been saved."</p> <div align="justify">  </div> <p align="justify"> <strong><span class="headline">Detect, model, warn - in time</span></strong></p> <p align="justify"> An effective tsunami warning system starts with a network of strategically deployed detectors. In the case of DEWS, these include broadband seismometers, land and ocean-surface based GPS instruments, tide gauges and ocean bottom pressure control devices. The different kinds of sensors provide complementary information that allows more accurate assessment of the risk of a tsunami.</p> <p align="justify"> The data generated by this suite of instruments is streamed via communication satellites to a central station in Jakarta, Indonesia for processing. State-of-the-art open source software called SeisComP3 developed by the German Research Centre for Geosciences (GFZ), the lead institute for the DEWS project prototypes, rapidly determines the magnitude and location of a seismic event.</p> <p align="justify"> "The former systems needed 11 or 12 minutes to detect a signal and locate the source," says Küppers. "The same can now be done in four minutes."</p> <p align="justify"> Once the system detects an earthquake powerful enough to create a tsunami, it begins to analyse and model the risk of a tsunami. If waves are detected from ocean bottom pressure sensors or newly developed GPS buoys at the sea surface, it's possible that a tsunami has been generated and will strike somewhere. The next question is where and with what run-up height.</p> <p align="justify"> Even with powerful computing capabilities, modelling an event as complicated as a tsunami in real time would take far too long. An earthquake along the Sunda arc - the source of the Boxing Day quake - can generate tsunami waves that hit the coast of Indonesia within 20 minutes.</p> <p align="justify"> The DEWS researchers solved that problem by using libraries of temblors of different magnitudes and source locations, coupled with detailed simulations of the waves they would create around the entire Indian Ocean coastline.</p> <p align="justify"> When an actual earthquake shakes the region, the DEWS system automatically finds the simulation that best fits the event, and uses that to determine which coastal areas are at risk.</p> <p align="justify"> "It's not possible to do all the modelling of wave propagation and direction immediately after the event," says Küppers. "But the system works well with our prefab models."</p> <p align="justify"> With 20 countries to warn and a Babel of languages to deal with, the DEWS team has to put as much effort into the linguistic challenges and politics of how to warn all these countries and their at-risk population as into the technological and computational infrastructure.</p> <p align="justify"> The system has a component to compose and distribute messages and another to control if messages have been properly received or not. In addition, it is a multilingual system that can distribute different messages to different people in different languages, says Küppers. "It was even more difficult politically to get all the players together at one table," he adds, "but we are well on our way to overcoming those problems as well."</p> <p align="justify"> The working system has been demonstrated in association with DEWS project conference. Decision-makers in local and regional authorities have expressed interest in the DEWS project working system.</p> <div align="justify">  </div> <p align="justify"> <strong><span class="headline">Bringing the benefits back home </span></strong></p> <p align="justify"> Building on the success of DEWS in the Indian Ocean basin, the focus shifts to Europe, where a tsunami may occur at any time either in the Mediterranean Sea or in the North-East Atlantic.</p> <p align="justify"> Greece, Turkey and Portugal are the countries at greatest risk, but all the nations bordering the Mediterranean could be safer once DEWS is implemented there as well. Many preliminary steps toward that goal will be taken by other EU-financed projects such as TRANSFER, NERIES and SAFER.</p> <p align="justify"> Perhaps the single greatest innovation flowing from DEWS is the realisation that minimising infrastructure damage and loss of life from a natural or manmade disaster requires an enormous amount of technical knowledge and a high degree of coordination. As a result, the consortium is advocating the development of a new profession - that of the ‘early warning engineer'.</p> <p align="justify"> "If you want to tackle these problems properly, you have to take the time and effort to involve everybody," says Küppers. "So we'd like to see people acquiring a new full-scale profession and be able to take care of the whole early warning field."</p> <p align="justify"> The DEWS project received funding from the Sixth Framework Programme for research.</p> <div align="justify">  </div> <p align="justify"> <a href=";tpl=article&amp;BrowsingType=Features&amp;ID=91371" target="_blank">&gt;&gt; Press release at ICT Results</a></p> Antje Treutler 2011-03-22T17:01:04Z DEWS demonstrations at the "Lange Nacht der Wissenschaften" (Long Night of Sciences) Antje Treutler 2011-03-28T12:00:50Z 2011-03-22T17:05:46Z <p> <img src=";groupId=10156&amp;t=1301313198753" style="float: left; width: 180px; height: 90px; " /></p> <p> An audience of round about 100 guests took the opportunity to see the DEWS-presentations in three different sessions.<br /> At the Long Night of the Sciences various institutes and research groups of Berlin/Brandenburg presents their research topics to the general public.
