The RapidSeis pilot project has reached its end, and has been presented at the RapidSeis worshop in Liverpool:

The main aim of this project (joint project of ORFEUS UNILIV and NESC) is to remove the barrier of uptake to the seismology community of an application that allows analyses of seismic waveform data. This will be achieved by embedding this analysis application in a community gateway, which already exists in the form of the NERIES web portal. The important barriers to uptake are the installation and understanding of the analysis package, the difficulty in transporting large amounts of data as input to an analysis, and direct visualisation of the results. RapidSeis will overcomes these barriers. We will use it to generate intuitive interfaces to the analysis application in the form of self-contained web portlets.
These portlets will be directly embedded in the community gateway and link to the data available in the Orfeus Data Center; the primary European centre for this kind of data. All the data and computing will be orchestrated via our technology, and the results, e.g. graphs of waveforms,will be presented to seismologists via the NERIES web portal.
Pilot project founded by JISC: Joint Information system Commitee, in collaboration with
Visualize your waveforms with Seisgram2K by Antony Lomax.
You can find the new tool in the myNeries detail page:
Below there`s a beta relase of the Web 2.0 NERIES iGoogle Gadget, which shows and gives access to the latests seismic waveform datasets composed by the users through the NERIES Seismic Data Portal.
You can add the gadget in your website or in your iGoogle page
In the last weeks we`ve been working on several back end and front end features.
Back End: Optimization of the users` waveform requests management
We have adopted ActiveMQ as our requests message broker. We foresee this as one the core tools to centralize and schedule all the incoming waveform requests at the ODC, that will be routed transparently to the nodes of the ArcLink network.
We aim to extend this system to serve not only the portal but also other client tools, eg Breqfast.
Front End: Dataset Rating
Through the NERIES portal and cyberinfrastructure, the users of the portal can search for eartquakes and waveform by aggreagating in a transparent way information coming from different and multi domain data providers, having access to a big amount of seismic stations (c.a. 600 at this early stage) available through the ArcLink network
The adoption of Web 2.0 technologies such as webservices, RDF, and feeds coupled with Ajax and interactive maps, gave us the possibility to search, combining and mashup the seismic information that are distributed over the internet
Each user can compose his own dataset , combining together earthquake parameters, station information, phases arrival times in a completely dynamic way, thus exempting the providers from "guessing", processing and then offering, pre-packed datasets.
The datasets are basically created on demand from the users themselves.
In order to improve our services we have implemented an easy to use rating system which will help us in tracking back how users search for data, giving them the possibility to provide a quality evaluation on the obtained dataset. A negative feedback will be notified to the organisation providing the data which compose the user`s dataset, whilst all the positive ones will be used to create a collection of user composed datasets and metadata that will be made available to the users either through the NERIES Data Portal or through RSS feeds.
Please, find below the screenshot of the requests detail page hosting the Rating functionality
All comments and ideas on how we could improve this service are more than welcome!!
We`ve got several times comments from seismologists and engineers about the issue of having the possbility to select data from stations available within a specific azimuthal and distance range from a specific event.
Therefore we have developed an experimental visual tool which gives the opportunity to define these boundaries directly on the map, within the Wave Exp portlet.
Please, find few screenshots of this feature below
The tool is accessible from the balloon which describes the event
The boundaries are defined visually on the map, starting from the lower to the higher boundary
At the end of the process the stations within the boundaries are selected and marked on the map.
Any idea about how this functionality could be improved will be more then welcome.
The Neries Data Portal Development Team
After the 6th-7th November - brainstorm session in Edinburgh, besides many long term ideas for new tools and collaborations, we also got several requirements from the group of users attending the meeting.
NESC brainstorming presentations
One requirement was to give to the users the possibility to reload a set of waveform requests previously submitted through the Waveform Explorer. We have been working on this during the last week and a first version of this funcionality has been published in our prototype.
Every request listed into the Waveform Cart can be automatically reopened within the Waveform Explorer and modified, either adding new events or stations, or changing the time period of a Time Mode Request
We are planning to include also a simple text editor which allows the users to edit and submit an XML file which represents the waveform request, but there are some specs details to take into account first.
Please follow this link to watch a demo video
A poster of the NERIES Data Portal will be presented at the next AGU Tuesday 16th December 1340h
and demo session will follow on Thursday afternooon in a booth already reserved for a couple of hours
An experimental version of a TauP Webservice is now available as a NERIES Portal Resource. It is currently used by the Wave eXp portlet in order to calculate the seismic travel times of P and S phases from the sources to all the selected stations.
The Wave eXp, thanks to the TauP Webservice, allows the user to specify the velocity model that must be used for the travel time calculation. Three models are already embedded into the service itself, but custom models can be also specified by the user who can provide the model name and the URL where the model file can be downloaded.
If you want to share your velocity model, just add (whereas you have the proper rights, otherwise ask to get those!) your "Velocity Model" resources into the QuakeML tab of the SMI Portlet, by filling in the form with the requested information. It will be listed between the "Available Models" directly within the Wave eXp portlet.
The WSDL of the experimental TauP webservice can be found always through the SMI Portlet, looking at the "Webservice" Data Resources.
