Uca-fukui Software Free Download May 2026

UCA (Universal Charting & Analysis) - Fukui is a Windows-based software package designed to process and visualize strong motion seismograms. Unlike generic charting tools, UCA-Fukui is tailored for the unique demands of earthquake engineering.

Key capabilities:

The software is particularly popular for working with data from K-NET, KiK-net, and K-NET Tsukuba – Japan’s dense strong-motion seismograph networks.


UCA-Fukui expects data in cm/s² for acceleration. If your input file uses other units (m/s² or gal), use the “Unit conversion” tool under ツール (Tools).

If you are involved in audio engineering, specifically in the design of loudspeakers or acoustic filters, you may have come across the search term "UCA-Fukui software free download."

This usually refers to a specialized set of acoustic simulation tools developed by researchers or entities associated with Fukui University (or related acoustic laboratories in Japan). These tools are often used for calculating specific acoustic parameters, filter design, or loudspeaker enclosure simulation.

However, finding a legitimate "free download" can be tricky and potentially risky. This guide explains what the software is, the risks involved in downloading it from unverified sources, and safe alternatives.

The typical filename includes UCA_setup.exe or UCA_Fukui_VerX.zip. Common version numbers are 2.x or 3.x. The file size is usually between 5 MB and 15 MB – very lightweight.

The installation usually includes sample .dat or .txt files from recorded earthquakes (e.g., 1995 Kobe, 2011 Tohoku). Open one → immediately you see three-component seismograms (NS, EW, UD).

If the software was hosted on a now-defunct university website, the Internet Archive (archive.org) is the safest way to retrieve old, abandoned software. This is legal and preserves digital history.
