Infrasound data from Norris Geyser Basin showing November 13, 2023, eruption of Steamboat Geyser

Detailed Description

Infrasound-array processing for the newly installed station YNB, at Norris Geyser Basin. Top panel shows the pressure waveform from one of the three elements that comprise the array, filtered between 1 and 15 Hz. Bottom panel shows the backazimuth from the station to the source. The direction from the station to Steamboat Geyser is indicated by the black horizontal dashed line. The colors represent how well the 3 elements in the array agree (Median Cross-Correlation Maxima, MdCCM), where values closer to 1.0 (red) indicate highly correlated and strong signals.
