Smart Selection & Scaling of Real Earthquake Records

SeismoSelect is a specialized tool designed for professionals who need to bridge the gap between seismology (earthquake records) and structural engineering (design and analysis). When you need real earthquake ground-motion records for structural or seismic analysis — and you want a systematic, defensible way to choose, scale, and retrieve them from strong motion databases worldwide — SeismoSelect is the efficient, professional tool designed precisely for that task. It helps you build code or project-compliant suites of ground motions quickly, reliably, and with minimal hassle.

What SeismoSelect Offers

  • Global database access

SeismoSelect connects to major strong-motion repositories — including the NGA West 2 Ground Motion Database, the NGA East Ground Motion Database, the ESM Engineering Strong Motion Database, the NGA-Subduction Database, and the New Zealand Ground Motion Database — letting you search and retrieve real accelerograms from around the world.

  • Personal Database

The Personal Database feature allows users to create, manage, and maintain their own collection of seismic records. Users can import external accelerograms, organize them into custom folders, and seamlessly integrate them into the selection workflow. Records stored in the Personal Database can be searched, filtered, and selected like in standard databases, enabling a unified and flexible record-selection process tailored to your individual needs.

  • Spectrum-based selection & scaling of suites

SeismoSelect evaluates how well candidate records match a target spectrum over a chosen period range. It then allows scaling of the selected records so that the suite’s mean, as well as the individual records, align with the target spectrum — ideal for nonlinear dynamic analyses or code compliance.

  • Flexible search & filtering criteria

Users can filter candidate records using a variety of criteria: target response spectrum, ground-motion parameters (e.g. PGA, PGV, Arias or Housner intensity), seismic event metadata (magnitude, faulting style, date, location), and site/record conditions (e.g. Vs30, epicentral distance).

  • Batch handling & efficient workflow

Instead of manually downloading and adjusting records one by one, SeismoSelect enables selecting, scaling, and downloading whole suites of ground motions in a streamlined, automated process — saving time and avoiding manual errors.

  • Connectivity with other Seismosoft packages

The selected record suite can be easily passed to SeismoMatch, in order to be further adjusted and exactly match specific target spectrum required by building codes or project specifications.

Why Engineers & Researchers Use SeismoSelect

  • To build robust, code-compliant ground-motion suites — Selecting and scaling records so that they match a target response spectrum ensures compliance with seismic design standards and provides defensible inputs for structural or performance-based analyses.

  • For efficiency and consistency — Manual selection and scaling of records is time-consuming and error-prone; SeismoSelect automates the process, ensuring consistency and repeatability across projects.

  • When working with multiple databases and diverse seismic contexts — Global databases and broad filtering options allow engineers to access records relevant to different regions, faulting mechanisms, site conditions or hazard scenarios.

  • For research, seismic-hazard studies, and site-specific design — Researchers and consultants dealing with seismic hazard, ground-motion variability or site-response analyses benefit from the ability to quickly compile, scale, and export suitable accelerograms.

Who Uses SeismoSelect

  • Structural & earthquake-engineering firms / design offices doing performance-based design, nonlinear dynamic analyses, or seismic assessment & design. They rely on SeismoSelect to build code or project-compliant sets of ground motions drawn from global databases, ensuring that input records meet spectral demands and project requirements.

  • Seismic hazard analysts & geotechnical engineers working on site-response studies, soil-structure interaction, or site-specific hazard characterization — needing real strong-motion records selected for appropriate magnitude, distance, site conditions (e.g. Vs30) and other metadata.

  • Engineering consultants & retrofit specialists preparing seismic-assessment reports, retrofit proposals, or performance-based design documentation — needing defensible, well-documented ground-motion suites aligned with code or project spectra.

  • Researchers & academic institutions involved in seismic-hazard research, statistical studies of ground-motion variability, vulnerability analyses, or comparative studies across different regions. They use SeismoSelect to filter and compile accelerograms from major databases into curated datasets for scientific analysis.

  • Government agencies, regulatory bodies and seismic-monitoring organizations that maintain or develop strong-motion libraries, code-calibration datasets, or national seismic hazard databases can benefit from SeismoSelect’s capacity to search, select, scale and download real earthquake records globally.

In short: SeismoSelect is used by structural engineers, geotechnical engineers, consultants, researchers, government agencies — anyone who needs real, code- or hazard-compliant earthquake ground-motion records for reliable seismic analyses, design or research.

New in v2026

  • Personal Database: The Personal Database feature allows users to create, manage, and maintain their own collection of seismic records. The records stored in the Personal Database can then be searched, filtered, and selected using the same criteria and tools available for the standard databases.

  • AI Assistant Integration: The new Seismosoft AI Assistant is now available within SeismoMatch to help you select the best matching parameters (period range, tolerance) and troubleshoot convergence issues instantly.
