Applications

Earthquake Location Finding (ELF)

•This application is based on HYPO71 and finds the location of earthquakes by scanning

seismic waveform data.

•This application is not compute intensive , but it is data intensive. The application can

be parallelized by scanning data files in parallel by multiple using worker nodes.

•A workflow can be generated automatically by a program corresponding to the time

intervals in which to look for earthquake

Fault Plane Solution (FPS)

Computes earthquake source parameters (strike, slip, dip)Inputs: Crust model: layer thicknesses, seismic velocities, densities, q-factor Actual seismic waveform data (in SAC format)

Output: Fault paramtheters

Useful for identifying tectonic structures that are not visible on earth’s surfaceComputationally intensive applicationA typical run that uses data from 50 stations takes 8 hours on a PCImplemented in Fortran/CContact: Mehmet Yılmazer , [email protected]

Massive Digital Seismological Signal Processing with the Wavelet Analysis(MDSSP-WA)

•Wavelet theory has matured in past years as new mathematical tool for time series analysis. •The continuous or discrete wavelet transforms and relevant plotting of the results in coordinate

system, scales versus time, shows striking similarity of the wavelet images, between different seismic

records, coming from the same source region or noticeable difference for records of earthquakes

occurred in different source region. •We assume that, those similar image patterns are due to same underlying geological setting while the

differences (usually for smaller scale) is due to different source mechanism and finer geological

structures. •In the first approximation of geological structure, similarities of the image patterns in domain of large

scale are noticeable even for the records from different source regions. •With massive processing of earthquake records we can define: (i) Common features of the

propagation path for the given seismic source region or to define empirical transfer function of the

media (ii) Calculation of the artificial seismograms, (iii) Determine the source region based on a

single earthquakes record (iv) Determine the more realistic attenuation curve of the selected feature

(parameter), very much needed in seismic hazard and risk analysis, (v) Mapping (coding) of the given

earthquake prone region in terms of selected parameters (vi)Seismic source parameters•Contact: Ljupco Jordanovski, [email protected]

NUMERICAL MODELING OF MANTLE CONVECTION – NMMC3D

• The outer part of the Earth consist of moving, rotating and interacting plates. •The motion of these plates suggest a large convective system in the Earth's 2900 thick layer, the mantle. •The numerical calculations suggested that the convective cells are formed by sheet-like elongated downwellings (subduction zones) and narrow, cylindrical upwellings (mantle plumes, at the hotspots). •The main goal of our research is the quantitative study of the structure and surface manifestation of mantle plumes and to make systematic investigation of the parameters influencing the character of mantle convection in 3D.•Contact: Bálint Süle, [email protected]

SEISMIC RISK ASSESMENT (SRA)

• Seismic Risk Assessment is very important for public safety and hazards

mitigation. •It is also important for the correct determination of earthquake insurance

premiums and also for understanding the social and psychological

effects of earthquakes. •Our aim is to develop an application framework to allow us to embed

alternative (deterministic, probabilistic etc.) models. •SRA application can be grouped into four main categories:

(i) Accessing Earthquake Catalogue,

(ii) Earthquake Source Model

(iii) Seismic Hazard Models

(iv) Producing Seismic Hazard Maps•Contact: Cevat Şener, [email protected]

Seismic Data Server Application Service (SDSAS)

•SDSAS is a JRA1 service that serves massive seismic data that are archived from national seismology centers using a high level interface that is easy to use/adapt. It serves official lists of earthquakes, stations , sensor information. •It keeps the details of where the data files reside are hidden by mapping high level user specifications (dates, hours, location etc.) to appropriate pathnames. •The SDSAS implementation will be done by using scripts to collect and organizing the seismic data by utilizing storage elements, LFC and AMGA . •C++ iterators can be used by applications to access station data, earthquake data and information about seismic waveform files.•Contact: Can Özturan, [email protected]

Seismic Data Server (SDS)

•SDS serves seismic data present in AMGA tables (station data,

earthquake data and information about seismic waveform

files - not waveform files themselves) through a web interface

that utilizes kml and Google Earth API.
