A small collapse of the Pu‘u ‘Ō‘ō crater at 6:14 a.m. HST today (May 1, 2019) was the last 'hurrah' for a GPS instrument located on the crater's edge (red circle). This station, designated PUOC, served faithfully throughout Kīlauea's 2018 eruption and was an important source of information on the shallow magma system of Pu‘u ‘Ō‘ō. The station's last reported position showed it moving rapidly to the southeast, consistent with motion into the crater (inset shows data transmissions from April 11 through this morning). Monitoring of Pu‘u ‘Ō‘ō is currently being accomplished by additional GPS and tilt stations farther from the edge of the crater. The larger equipment installation near the solar panels was not affected by this morning's collapse and continues to function. However, contingency plans are in place in case collapses of the crater edge continue. USGS photo by Ingrid Johanson on March 18, 2019, annotated on May 1, 2019.
