Scientists use a laser diffraction particle size analyzer to examine fine ash from the 2018 Kīlauea summit explosions. The research examines fine ash (grains 1 mm to 1 micrometer) and investigates the processes of eruption, fragmentation, and respiratory health hazards (PM10, PM2.5). USGS image by A. Van Eaton

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 I. Johanson on March 18, 2019, annotated on May 1, 2019.

This image is from a temporary monitoring camera on the west rim of Kilauea Caldera. The camera is looking E towards the bottom of the newly enlarged Halemaʻumaʻu crater, although the deepest part of the crater is not visible from this vantage point. The crater from left to right (roughly NNE to SSW) is approximately 1 km (0.6 mi) across. The depth of the crater in the visible image from the rim is several hundred meters.

HVO geologists (one shown here for scale) examined Kīlauea Volcano's 2018 lava flow near Isaac Hale Beach Park on March 29. This part of the lower East Rift Zone fissure 8 flow is mostly "toothpaste lava"—an informal name for secondary spiny pāhoehoe lava that oozed out from the stalled primary ‘a‘ā flow that reached the coast. This lobe, classic toothpaste lava, is about 3-4 m (9–13 ft) thick and about 70 m (76–77 yds) long. USGS photo by M. Patrick.

After magma drained from Pu‘u ‘Ō‘ō on April 30, 2018, the crater was roughly 356 m (1168 ft) deep, with the upper part of the crater flared and the deeper part a narrower cylindrical shaft. Collapses on the crater walls have since enlarged sections of the crater and filled the deepest part with rockfall debris, creating a much different crater geometry—as shown in this comparison of models from May 11, 2018, and March 18, 2019. Today, the deepest portion of the crater is 286 m (938 ft).
