TRIDEC Cloud

• Cloud-based and web-based platform to open up new prospects for Tsunami Early Warning and Mitigation Systems

• Combination of several complementary cloud-based services merged into one platform for– Web-mapping of hazard specific geospatial data,

– Handling, sharing, and communicating threat specific information

– Collaborating in a distributed environment

• Modern web-based Graphical User Interface– Operators in warning centers and stakeholders of other involved parties (e.g. CPAs,

ministries) just need a standard web browser

Features

TRIDEC Cloud – Earthquake Information

• Integrates latest earthquake information from http://geofon.gfz-potsdam.de

• Simple REST API enables integration of other national and international systems

• List displays earthquake events with information on– Magnitude, location, time,

– Dip, strike, rake,

– Classification based on simplified decision matrix,

– Prediction based on attached simulation either computed automatically or manually in the background

• Map displays location of earthquake events

TRIDEC Cloud – Sea Level Measurements

• Integrates historic and real- time sea level data from http://ioc-sealevelmonitoring.org

• Simple REST API enables integration of other sea level stations and systems

• Users select the sea level stations based on their needs• Map displays position of the sea level stations• Small diagrams below the map display the measurements for sea

level each station– In default mode diagrams show the real-time data for the stations– For events selected by the user diagrams display the relevant sea level data for the selected

event– If a simulation for an event has been computed either automatically or manually diagrams

display additionally the predicted sea level data– Comparison of real data with simulation data for sea level stations

• Interactive diagrams for a detailed analysis and picking– Select and open with a click on a small diagram– Sliders for picking period and amplitude values or form to configure values manually– Picked values in the interactive diagram can be enabled for integration in warning

TRIDEC Cloud – Simulation Computation

• On-demand tsunami predictions based on actual source parameters

• Manual and automated background computation using graphics processing units (GPU) for instant tsunami propagation calculations

• On-demand tsunami simulations are computed for an event either automatically or manually by a GPU Cloud– With tsunami travel times (TTT), estimated times of arrivals (ETA), estimated wave

heights (EWH/SSH), and mareograms

– For visualization purposes with isochrones and tsunami-jets on a map

– For visualization and analysis with time series in diagrams

– For further analysis and processing purposes with tsunami forecast points (TFP) and tsunami forecast zones (CFZ) important for generating warning messages

TRIDEC Cloud – Virtual Scenario Player

• Enables training and exercises with virtual scenarios

• With special accounts operators and others involved are able to train skills and to prepare for large exercises and real events

• For training purposes virtual scenarios are playable with an acceleration to run prepared scenarios faster than in reality

• Selected scenarios in NEAM region and other regions in the world are already available

• New scenarios might be added for– Internal training, e.g. weekly, or

– Extended monthly communication tests

TRIDEC Cloud – Timeline

• Tracing of information and activities related to an initial event sorted by time– Earthquake events with first information and follow-up refinements

– Simulations automatically or manually processed for earthquake event updates

– Warning messages sent

• http://youtu.be/Q5Znr61qUEw

TRIDEC Cloud – Message Dissemination

• Generation of warning messages with static and dynamic information based on instant computation of a tsunami simulation

• Review, modification, and addressing of generated messages in one form

• Dissemination via– E-mail

– Fax

– FTP (and thus GTS)

– SMS

– Cloud Messages

– Shared Maps

• Messages follow the format defined by ICG/NEAMTWS (initial and ongoing information-watch-advisory messages and messages for tsunami end or cancellation)

• http://youtu.be/ByVpGh40Tqg (mail), http://youtu.be/pGLyoQ5M6HA (fax), and http://youtu.be/bEIq3HY4gI8 (FTP/GTS and SMS)

TRIDEC Cloud – Cloud Messages

• Cloud messages are sent internally within the TRIDEC Cloud to other users

• Complementary to e-mail, fax, FTP/GTS, and SMS

• Contain text information and integrate interactive and dynamic event data and simulation data

• Recipients are enabled to interact dynamically with the map and diagrams beyond traditional text information

• http://youtu.be/l8XJpql_tLM

TRIDEC Cloud – Shared Maps

• Maps and related data are shared with others by using URL addresses– 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 a web browser and interact immediately with the map

• Works even if the recipient is not a TRIDEC Cloud user

• If the recipient is a TRIDEC Cloud shared maps can be copied into the recipient's user account– Users are enabled to fully interact with shared maps as they know it from own events

– Modify and reprocess the shared map or use it for warning message dissemination

• http://youtu.be/3QhxC0PBTkg

TRIDEC Cloud – Monitoring and Training

• Monitoring mode– Provides important functionality required to act in a real event (see above)

– Integrates historic and real- time sea level data from http://ioc-sealevelmonitoring.organd latest earthquake information from http://geofon.gfz-potsdam.de

– Simple REST API enables integration of other systems

• Exercise and Training mode– Enables training and exercises with virtual scenarios

– Integrates Virtual Scenario Player

– Corresponds to Monitoring mode

– Operators and others involved are able to train skills and prepare for large exercises and real events

Exercise Runsin the Fringe of NEAMWave14

Background

• Opportunity provided by NEAMWave14 to test the TRIDEC Cloud

• Collaborative activity based on previous partnership and commitments at the European scale– GFZ German Research Centre for Geosciences (GFZ)

– Kandilli Observatory and Earthquake Research Institute (KOERI)

– Portuguese Institute for the Sea and Atmosphere (IPMA)
