SPAS

Seismology research is a field of major relevance nowadays, what with all the campaigns meant to increase awareness of natural disasters and their implicit repercussions.

SPAS is one of the software solutions that might come in handy to professionals involved in the study of earthquakes and who are in search of a powerful tool to help them in their scientific endeavors.

Before getting more in-depth into the program’s characteristics, it must be noted that its installation should let users run it in less than a minute and then be greeted by an approachable interface.

The GUI is designed in accordance with the program’s 3-phase modus operandi, which entails pre-processing, analysis, and post-processing.

At this point, a few words are in order to present the core functionality the developers had in mind when creating the product. It must be said that the program was designed as a seismic processing and analysis utility that is capable of reading data collected during CPTUs measurements.

One of SPAS’ specific features is that it supports both shear and compression waves. Besides, the fact that it is able to process left and right signals independently and make an assessment based on an average value should make it stand out from the crowd.

It is worth knowing that defining the boreholes is the step a user needs to take prior to pre-processing. Thus, it must be noted that the program is able to recognize multiple boreholes in a single project file and that defining the properties of the added boreholes is also required. What this means is that you are asked to settle on a signal sampling ratio, horizontal distance from source, geophone offset, and display FTT frequency.

As for the analysis means the program resorts to, cross-correlation is the algorithm it is based on, with the results being displayed in a relatively short amount of time. An important addition to the program’s feature set is its hand calculation component, which allows you to adjust the value of shear waves.

SPAS is a piece of software addressing users with high expertise in the seismology domain, its applicability being related mainly to analyzing seismic piezocone and seismic downhole tests.
