Graph of GPS line-length across the Mauna Loa summit, 2022–2023

Detailed Description

Plot showing the distance between two GPS stations on Mauna Loa from February 2022 to November 2023. Station MOKP is on the north side of Mokuʻāweoweo and station MLES is east of Mokuʻāweoweo. This plot shows how the distance between these two stations increased before the 2022 Mauna Loa eruption, indicating that the volcano was inflating. In the months following the 2022 eruption, the deformation rates have slowly declined, though they remain relatively high. USGS plot.
