Build, Manage, and Analyse Your Own Database of Earthquake Records.

SeismoSpect is a unique software designed to simplify the management and signal processing of large suites of strong-motion records. While SeismoSignal focuses on the detailed analysis of individual records, SeismoSpect allows you to create a personal library of ground motions, save them in a single manageable file, and perform batch processing and spectral comparisons efficiently.

It is the ideal tool for consulting engineers and researchers who need to organize, and analyse collections of accelerograms for multiple projects or parametric studies.

Your Personal Seismic Library

Stop managing hundreds of loose text files. SeismoSpect consolidates your data:

  • Unified Database: Import accelerograms from various sources (PEER NGA, SMC, ESM, etc.) and save them into a single, organized project file.

  • Metadata Management: Keep your records organized with their associated signal processing settings (filters, baseline corrections) preserved for future use.

  • Rapid Sharing: Share your entire curated library with colleagues or clients by sending just one file.

Batch Signal Processing

Apply consistent processing rules across your entire dataset simultaneously:

  • Batch Baseline Correction: Apply polynomial fitting (up to 3rd order) to all records to remove displacement drift.

  • Batch Filtering: Implement causal/acausal filters (Butterworth, Chebyshev, Bessel) across the entire suite to ensure frequency content consistency.

  • Automated Parameter Calculation: Instantly compute Peak Ground Values (PGA, PGV), Arias Intensity, Durations, and other intensity measures for every record in your library at once.

Spectral Comparison & Mean Response

Evaluate how your record suite performs against design codes:

  • Mean Spectral Response: Automatically calculate the mean response spectrum (and mean +/- standard deviation) of your entire collection.

  • Target Comparison: Compare your suite’s mean spectrum against a reference target spectrum defined by Eurocode 8, ASCE 41-23, ASCE 7-22, or 25+ other national codes.

  • Suite Verification: Quickly identify which records outlier the target and adjust your selection to meet code compliance for time-history analysis.

Who Needs SeismoSpect?

SeismoSpect is the ideal tool for anyone who works with large sets of earthquake ground-motion records and needs to process, analyse, compare, or organize them efficiently. It is widely used across the earthquake-engineering, hazard-assessment, and research communities, including:

  • Seismologists & Ground-Motion Analysts

  • Structural Engineers

  • Geotechnical Engineers

Engineers performing site-response analyses, liquefaction assessments, or soil-structure interaction studies rely on SeismoSpect to generate accurate ground-motion parameters across many records and select appropriate input motions for modelling.

Experts working with strong-motion stations or earthquake datasets need a robust tool to baseline-correct, filter, catalogue, and analyse large collections of accelerograms. SeismoSpect provides rapid batch processing and a rich set of spectral and intensity-based metrics.

Professionals conducting seismic design, performance-based assessments, or nonlinear time-history analyses need consistent, clean, and well-processed accelerograms. SeismoSpect helps them build record libraries, compute spectra, and evaluate sets of records against target design spectra.

  • Government Agencies & Seismic-Hazard Organizations

  • Research Institutions & Academic Users

  • Engineering Consultants & Design Offices

Authorities responsible for seismic monitoring, hazard mapping, code development, or maintaining national ground-motion libraries need a tool capable of organizing datasets and comparing motions to regulatory spectra — a core strength of SeismoSpect.

Universities, research labs, and students benefit from SeismoSpect’s ability to handle extensive datasets, compute advanced seismic parameters, and support studies related to seismic hazard, ground-motion characteristics, and earthquake-engineering research.

Consultancies preparing seismic evaluation or seismic hazard reports, use SeismoSpect to streamline ground-motion management, generate mean spectra for record suites, and produce technical figures and tables ready for incorporation into deliverables.

New in v2026

  • AI Assistant Integration: The new Seismosoft AI Assistant is integrated to help you troubleshoot batch processing errors and advise on appropriate filtering parameters for your specific dataset.

Key Capabilities

  • Create organized databases of ground-motion records for ongoing seismic-hazard or structural-analysis projects.

  • Compare recorded motions against code-based spectra (e.g. for compliance checking, design validation or regulatory submission).

  • Flexible Import: Reads single-value, multi-value, and time-acceleration formats. Also import records stored in files with specific format (PEER NGA, ESM, SMC format).

  • Visual Interface: Fully visual environment for inspecting time-histories and spectra.

  • Seamless Export: Copy numerical results and high-quality plots for all records to Excel or Word in a single click.

Ideal For

  • Organizing Ground Motion Databases

  • Batch Processing of Accelerograms
  • Verifying Record Suite Compliance
  • Comparing Spectra against Code Targets
  • Statistical Analysis of Ground Motion Parameters

Completely visual interface. No input or configuration files, programming scripts or any other time-consuming and complex text editing requirements.

Due to its full integration with the Windows environment, SeismoSpect allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself.
