Detailed Description
The figure shows changes in the propagation speed of ocean noise signals (red filled circles) through Kīlauea volcano from September 2020–February 2021. Positive values indicate a speedup in the propagation speed of ocean noise while negative values indicate a velocity slowdown. The black bar around each red circle indicates the uncertainty in the relative velocity change measurement.
