Interactive Seismic File Editor

View, edit, and manage seismic trace data and headers.

Import MiniSEED seismic files to explore, edit, and export both trace headers and waveform data. Visualize each trace in an interactive chart, update metadata such as station codes, timestamps, or network info, and make precise edits to individual trace data samples. Remove unnecessary traces or headers, then export the modified stream back to MiniSEED. A powerful tool for detailed seismic data management.

User guide

Upload a MiniSEED seismic file to explore its contents. Click 'Show Traces Info' for a summary of each trace’s metadata. View trace waveforms in interactive plots and use the toolbar above each plot to download header info or data samples individually. Use the 'Trace Info' menu to edit trace headers or delete traces. Once your edits are complete, export the updated file in MiniSEED format using the 'Download to MSEED' option.

Note: This toolset is part of a personal seismology project currently maintained by a single developer. It's hosted on a free-tier server, so you might occasionally experience delays or temporary issues. If the server appears unresponsive, please wait a few seconds — it may be starting up (cold start).
