    Look ahead with the TRIDEC Cloud

    In times of cloud computing and ubiquitous computing the use of state of the art technology concepts and paradigms have to be considered even for early warning and fast response systems. Based on the experiences and the knowledge gained in three research projects new technologies are exploited to implement a cloud-based and web-based prototype to open up new prospects.

    This prototype merges several complementary external and in-house cloud-based services into one platform for automated background computation with graphics processing units (GPU), for webmapping of hazard specific geospatial data, and for serving relevant functionality to handle, share, and communicate threat specific information in a collaborative and distributed environment.

    TRIDEC Cloud for Tsunami

    Warning centers' staff and stakeholders of other involved parties just need a standard web browser to access a full-fledged early warning system – in its current version for tsunamis. It provides important functionality required to act in a real event and integrates historic and real- time sea level data and earthquake information.

    On-demand tsunami simulations are computed for an event either automatically or manually by a small GPU cloud working in the background and responsible for immediate processing.

    Thus tsunami travel times, estimated times of arrival and estimated wave heights are available immediately for visualization purposes with isochrones and with tsunami-jets on a map and for further analysis and processing purposes with tsunami forecast points and coastal forecast zones, e.g. important for generating warning messages. Messages are disseminated by e-mail, fax, FTP/GTS, SMS, and other complementary channels for sharing information. Furthermore, the system enables training and exercises with virtual scenarios. Thus operators are able to train their skills and to prepare themselves for large exercises and real events.

    Release 'Silvia'

    With the help of our friends in Malaga the latest TRIDEC Cloud release 'Silvia' now integrates Tsunami-HySEA. We are more than happy to announce this piece of great news.

    The latest release demonstrates the modular character and the extensibility offered by the technical framework working in the background. Moreover, it shows that interoperability and a community spirit have been and will be crucial for the future development. We hope to take the right path with opening the system and collaborating with others so that the community can make the most out of the TRIDEC Cloud and other software developed and used by the community. Hopefully, this release helps in identifying opportunities we may take together on future paths.

    Have fun making use of HySEA for testing purposes in this initial integration version. We're looking forward to receiving your feedback and comments so that we can improve the user experience according to your needs. A short demo is available at https://youtu.be/tmbfkmn38Yw

    Release 'Raluca'

    It has been a looong time since we announced our last release. However, the release train is rolling again and we are happy to announce the latest release 'Raluca'.

    This release features global coverage, region specific messages and an extended simulation tasking.

    Global coverage has been one of the central aspects while implementing the TRIDEC Cloud. So a global simulation computation has been available from the early beginnings two years ago. However, this time all regions are supported with Tsunami Forecast Points, Coastal Forecast Zones, Forecast Polygons or whatever you name it in the different regions be it the Pacific Ocean, the Indian Ocean, the Caribbean Sea, the Mediterranean or any other region.

    This means computation results are now mapped to the region specific polygons and points of interest so that generated warning messages automatically consider these polygons or points and include them automatically. So you are ready to go in case you have to send a message with forecasting details to others.

    Furthermore, the TRIDEC Cloud now supports region specific messages. A first validation has been carried out in parallel to the CARIBE Wave this year serving the required message format in the Caribbean Sea's region. So on request it's possible to switch from the standard format to your desired message structure.

    Finally, the standard parameters for simulation computations included the parameters magnitude, strike, dip and rake. But from now on you may even use length, with and slip parameters.

    Have fun exploring the new features or just have a look at https://youtu.be/FOP_nNkbYdk

    Release 'Pedro'

    Even if it has been a key aspect to consider the user experience when implementing the TRIDEC Cloud we know that there is room for improvement by adding convenience to existing functionality.

    The minor release 'Pedro' addresses this issue so that you are able to select stations for specific regions with little effort.

    In case of a major event this should help you to switch quickly from one region to another to trace sea level measurements, i.e. in the Indian Ocean, the Pacific, the Caribbean Sea, the North-eastern Atlantic, and the Mediterranean and connected seas.

    Try it yourself or find a short demo at http://youtu.be/0Edvdac5Xiw

    Release 'Öcal'

    The latest release 'Öcal' complements the data approach by integrating data from other systems.

    Just click the 'Inspect event' icon displayed for each earthquake event and get further information on the event coming from other sources. Different sources have been integrated in different ways either exclusively in a dedicated panel such as for GEOFON or in a panel listing all sources available. However, if you want to inspect the event data of the different sources in detail just follow the reference 'Go to source'.

    Find a short demo at http://youtu.be/hBSp05tLahE or try it yourself.

    Release 'Nicos'

    It's time for the next TRIDEC Cloud release. Release 'Nicos' features the compilation of reports. Now you can download, send, and print PDF-based reports.

    So far, reports contain warning messages with prepared content and dynamic event data, depict a location map with simulation data, and refer to a shared map.

    Reports allow the integration of any other information required. So let us know your wishes and demands.

    Try it yourself or watch the demo at http://youtu.be/I3tkPCIbSrA

    Release 'Marzia'

    The latest TRIDEC Cloud release named 'Marzia' allows taking data from the TRIDEC Cloud to your systems.

    How does it work? A simple interface (API) is used to get the data for embedding it in other places. Just open the API documentation at http://trideccloud.gfz-potsdam.de/apidoc/ to get started.

    Want to see it in action? Just have a look at these examples:
    http://trideccloud.gfz-potsdam.de/embed-data/?id=gfz2015knrf
    http://trideccloud.gfz-potsdam.de/embed-data/?id=gfz2011ewla

    Each example is a dynamically generated website that provides information for earthquake events. At the top of the website you'll find information from the primary source, which is GEOFON in this example. Of course, in your case it would be your public or protected website or any other of your systems.

    If you scroll down the example website you'll find automatically integrated information from the TRIDEC Cloud. If an earthquake exceeds critical thresholds than the TRIDEC Cloud instantly computes a simulation within seconds with all the nice features you already know. The computation result then can be accessed over the API mentioned above. Thus maps and messages can be embedded and integrated for further use in any other system.

    Want to try it yourself? Just sign-in with your account and open the configuration. Open the tab named 'General', generate an API key and allow the API usage for your account. Then follow the documentation.

    As always, there is a video showcasing the new feature: http://youtu.be/i9uQe9c7Y90

    Release 'Luis'

    It has been a while since we announced a new release. So it's time again and we are back with the TRIDEC Cloud release 'Luis'. Release 'Luis' enables notifications via short messages and e-mail. Just configure your mobile phone number and/or an e-mail address in the TRIDEC Cloud and notifications are enabled for your account.

    In case you are interested in getting instant notifications for specific events you are able to set an earthquake magnitude threshold, decide if you want notifications for off shore earthquake events only, and choose if preliminary warning messages are integrated in notification e-mails sent to you.

    Additionally, notifications for event updates help to keep track of important changes, e.g. when moment tensor solutions are available or when automatic simulation computations finished processing.

    So what does that mean for you? Whenever an earthquake exceeds the magnitude threshold you instantly get a notification message via short messaging and via e-mail. The availability and change of moment tensor solutions is immediately announced, too. Finally, if all relevant parameters for a simulation computation are available and classified as critical then the result of an automatically started simulation computation is sent to you with a notification. Thus notifications include a URL address referring to an automatically created interactive shared map displaying the computed simulation result. Furthermore, notifications include a preliminary warning message with classification and information on tsunami forecast points for the NEAM region and information on coastal forecast zones for the IO region.

    So notifications have the power to provide relevant and critical information automatically generated within minutes. In case of a threat this feature might help to save valuable time to be responsive, even if you are on the go.

    We would be more than happy if you could test this new feature and could kindly provide feedback. The configuration is easy. Just sign-in with your account and go to the configurations menu. If you want to sneak a peek before testing then here is the recording you need: http://youtu.be/hMoHV1SZwPQ

    Release 'Kenneth'

    We are excited to show off fantastic features coming with the latest TRIDEC Cloud release 'Kenneth'.

    Release 'Kenneth' covers the Indian Ocean region with Coastal Forecast Zones (CFZs) and integrates computed forecast information for CFZs in messages. Additionally, a Layer Switcher gives you the control to display travel times, wave jets, and CFZs (as well as Coastal Forecast Points in the NEAM region) for computed instant tsunami propagation calculations.

    Try yourself or find the demo at http://youtu.be/Enuq_bvnDYE.

    Release 'Irene'

    This release integrates changes in the background you can't see so far. Boring! We know. But you will enjoy the features of the future releases this year which are based on these changes. We'll keep you updated, so stay tuned.

    However, two additional features are available with this release. By now the platform not only integrates earthquake events with moment tensor (MT) solutions but also all other earthquakes. Thus, you are able to run instant tsunami propagation calculations manually with worst case parameters configured by yourself before the MT solution is available.

    Since a list and a map with all earthquakes available might become hard to handle a filter option has been added. With the filter you are allowed to reduce the set of listed earthquakes by defining a magnitude range and by selecting MT solution events, offshore events, and events with automatic computations only.

    Test it yourself or check out the video at http://youtu.be/Kk2Wnotda9g.

    Release 'Hélène'

    We are happy to announce TRIDEC Cloud release 'Hélène' integrating two exciting convenience features.

    The first feature is called 'Cloud Message'. Cloud messages are sent internally within the TRIDEC Cloud to other users. They are complementary to e-mail, fax, FTP/GTS, and SMS and not only contain text information. Additionally cloud messages integrate interactive and dynamic event data and simulation data. Thus the recipients are enabled to interact dynamically with the map and diagrams beyond traditional text information. Please test it yourself with your colleagues or check out the video at http://youtu.be/l8XJpql_tLM.

    The second feature is called 'Share Map'. Maps and related data are shared with others by using URL addresses. Just send send a link either to a list of closed recipients via e-mail, or to the public via twitter, Google Plus, and Facebook. Recipients open the web address of the map in their web browser and thus can interact immediately with the map. This feature works even if the recipient is not a TRIDEC Cloud user. But if the recipient is a TRIDEC Cloud user the magic continues - shared maps can be copied into 'My List' of the recipient's user account. Thus users are enabled to fully interact with shared maps as they know it from own events. They may modify and reprocess the shared map or use it for warning message dissemination. Test it or check out the video at http://youtu.be/3QhxC0PBTkg.

    Release 'Gerasimos'

    The latest TRIDEC Cloud release integrates a new feature that allows tracing of activities related to an event. We call it a 'Timeline'.

    We have recorded a short video showing this feature in action while examining earthquake events, processed simulations, and warning messages sent for the replay of the Portuguese NEAMWave14 scenario introduced in the previous release.

    The video is available at http://youtu.be/Q5Znr61qUEw

    Release 'Fernando'

    This release enables training and exercises with virtual scenarios. With special accounts operators are able to train their skills and to prepare themselves for large exercises and real events.

    Please find a demo at http://youtu.be/CaRXYR4PE8s. The video shows the TRIDEC Cloud in the 'exercise mode' exemplary with the Portuguese NEAMWave14 scenario. Please note, that the virtual scenario shown in this video is played with an acceleration factor and thus runs 10 times faster than in reality. The Greek, Turkish, and French NEAMWave14 scenarios are available amongst others for training and preparation of the international tsunami exercise NEAMWave14.

    Release 'Emelie'

    We are excited about the new TRIDEC Cloud release named 'Emelie'. This major release is now online with important functionality required to act in a real event - check it yourself at http://youtu.be/C56L4qj9aRA.

    Release 'Emelie' complements already available earthquake information and integrates historic and real-time sea level data. The map displays the position of the sea level stations with small icons and small diagrams below the map display the data. In default mode the diagrams show the real-time data for the stations. But if you select an event on the list left to the map then the diagrams display the relevant sea level data for the selected event.

    Moreover, if a simulation for an event has been computed either automatically or manually by using 'modify and reprocess' then diagrams not only show the real sea level data but also the computed sea level data. Thus you are able to compare both lines with each other.

    Please select an event (preferably with a computed simulation) and open a diagram for analysis and picking. Just click on a small diagram below the map and an interactive and bigger diagram is opened. Use the sliders for picking period and amplitude values. Or use the form itself to configure these values manually. Picked values in the diagram can be enabled for integration in warning messages by enabling the checkbox above the picking form. Warning messages then can be sent by e-mail, fax, FTP/GTS, and SMS.

    Finally, you are able to select the sea level stations based on your needs. Just open the configuration (click the gear-wheel button) and select the 'Stations' tab in the pop-up dialogue.

    Releases 'Ceren' and 'Dov'

    The new feature of the release 'Ceren' is the dissemination of short messages to mobile phones. Enjoy the demo video at http://youtu.be/bEIq3HY4gI8 or use your own account for testing. If you test it yourself, then please use the format for international telephone numbers, i.e., the + (plus sign) followed by the international country calling code (e.g. +90 for Turkey and +351 for Portugal). We have pre-set accounts with a Twilio account that we use for testing. Leave the SMS settings unchanged if you want to give it a quick try. However, if you are interested in further testing by making use of your own Twilio account then please sign-in and open the configuration (click the gear-wheel button). Select the 'Messages' tab in the pop-up dialogue, expand the 'SMS' group and enter your Twilio SID, token, and number.

    Moreover, with the release 'Dov' you're now able to send warning messages not only via e-mail, fax, and SMS but also via FTP, and thus you're able to disseminate messages via GTS. The FTP dissemination is configurable. Please follow the instructions provided for fax and SMS and you will find the configuration fields for FTP/GTS. To get you started we already pre-configured accounts with a default FTP location.

    Release 'Begona'

    Enjoy bug fixes and some interface polishing, and test the new feature of this release which is fax dissemination.

    If you still have no account for testing then get one or enjoy the video at http://youtu.be/pGLyoQ5M6HA. In case you want to test it on your own, we have pre-set accounts with an InterFAX account that we use for testing. Leave the fax settings unchanged if you want to give it a quick try. However, if you are interested in further testing by making use of your own InterFAX account please sign-in to the TRIDEC Cloud and use the gear-wheel button left to the sign-out button in the upper navigation. Then select the 'Messages' tab in the pop-up dialogue, expand the 'Fax' group and enter your InterFAX username and password. You may watch the video mentioned above to get some visual guidance.

    Release 'Alessandro'

    We are happy to announce a new release of the TRIDEC Cloud.

    In previous versions users have been able to compute on-demand tsunami simulations by a small GPU cloud working in the background and responsible for immediate processing. Later versions have been used to improve the user experience and stability, and to integrate further compute features such us tsunami-jets (sea level isohypses, wave height areas, or whatever you call them). Furthermore, the computation of tsunami forecast points has been integrated. You may try the compute feature by selecting one of the pre-set events, e.g. for the Gulf of Cadiz or Eastern Med regions, listed at the bottom in the 'Compose' tab.

    Then successive versions have been planned as more frequent releases. Due to the fact that each release still is an early Alpha version, new releases couldn't be called Beta. So new releases are numbered alphabetically and the first official Alpha Release is called 'Alessandro'.

    With release 'Alessandro' the previous development is officially bundled and additionally a new feature has been introduced. Now users are able to start the generation and sending of warning messages via email after the quick on-demand computation of a tsunami simulation. So give it a try and compute one of the pre-set events listed at the bottom in the 'Compose' tab. After processing you should test the generation and sending of warning messages via email (just use the paper airplane button). Or just check out the video at http://youtu.be/ByVpGh40Tqg

    Early Alpha Release

    The first prototype version addressed the implementation and integration of a GPU-accelerated application for instant tsunami propagation calculations in the context of early warning and has been presented the first time at a conference in April 2014.

    The integration of GPU accelerated simulation computations have been an integral part of this prototype to foster early warning with on-demand tsunami predictions based on actual source parameters. However, the platform is meant for researchers around the world to make use of the cloud-based GPU computation to analyze other types of geohazards and natural hazards and react upon the computed situation picture with a web-based GUI in a web browser at remote sites. This early alpha version was set-up for demonstration purposes to give the concept a whirl and to shape science’s future.

    Further information is available in the conference abstract, the corresponding slide deck, and in a complementary video at http://youtu.be/6xFJZzWNi7o.

    Currently, we use a rough and simple threshold mechanism to identify the tsunami potential of an earthquake. If the location of the earthquake is inland, deeper than 100km, or has a magnitude less than 5.5 then we don't consider the earthquake for any wave propagation computation. However, if you think the earthquake is relevant for computation then you can do so by using 'Modify and reprocess'.

    Anyhow, in the near future we plan to use an improved mechanism by adopting region dependent decision matrices defined by the UNESCO-IOC ICGs, that is ICG/NEAMTWS, ICG/IOTWS, ICG/PTWS, and ICG/CARIBE EWS.
