This dataset comprises unprocessed high-speed video recordings of eruptive events at Strokkur Geyser, Iceland, captured during a field campaign from August 23–27, 2023. The videos are provided as sequences of individual TIFF files for each frame, enabling detailed analysis of the geyser’s eruption cycle. These high-resolution recordings, made using a Chronos 2.1-HD high-speed camera at 500 frames per second with a resolution of 1920×1080 pixels, are specifically focused on capturing the growth and rupture of the water bulge, rather than the resulting geyser fountain. Each video is, on average, 4.29 seconds long, providing high temporal resolution of these rapid processes.

The dataset includes 29 analyzed events, selected for their detailed capture of the water bulge dynamics. These videos document critical stages of the eruption process, including the bulge’s growth, rupture, and associated fluid dynamics. The recordings were synchronized with infrasound and audio data collected during the campaign, allowing for integrated analysis of acoustic signals and visual observations.

This dataset provides a valuable resource for studying water bulge dynamics and associated acoustic emissions. It complements other geophysical data collected during the campaign and offers insights into surface and subsurface processes relevant to geysers and analogous volcanic systems.
