The ah file extension identifies a binary seismogram format used in seismology. SEED is an international standard for exchanging earthquake data, while AH is a waveform format used to store associated seismogram data.
An AH file contains recorded seismic waveform samples together with associated recording metadata, such as information about the station and channel. It is intended for specialist seismic-analysis software rather than ordinary document or media applications.
Open an ah file with seismic-analysis software that supports the AH format. The Seismic Analysis Code (SAC) can read AH waveform files.
If the file does not open, it may require a program that supports the specific AH variant or the original SEED data associated with it.
An AH file can be converted to a seismic-analysis format such as SAC by opening it in SAC and writing the waveform in SAC format.
Conversion is normally performed with specialist seismology software. Renaming the file or converting it as a text document will not convert the waveform data.
