Mizzou Geology Club

Hey everyone don’t forget we have a club meeting today from 4-5. We will be making designs for geology clubs new t-shirts. As well as talking about up coming events. Be there or be monoclinic.

Rockfall generates a short-lived explosion at Halema‘uma‘u crater, at 8:27 a.m. HST, May 9. An ash column rises from the Overlook crater at the summit of Klaue...a Volcano today. The USGS-Hawaiian Volcano Observatory's interpretation is that the explosion was triggered by a rockfall from the steep walls of Overlook crater. This photograph was taken at 8:29 a.m. HST on May 9, from the Jaggar Museum overlook. The explosion was short-lived. Geologists examining the ash deposits on the rim of Halema‘uma‘u crater found fresh lava fragments hurled from the lava lake. This explosion was not caused by the interaction of the lava lake with the water table. When the ash cleared from the crater about an hour after the explosion, geologists were able to observe the lava lake surface, which is still above the water table. #usgs #hvo #hawaiianvolcanoobservatory #kilauea #volcano #PuuOo #KilaueaErupts #LeilaniEstatesEruption #leilaniestates

This video of Halema‘uma‘u lava lake from the evening of May 7 shows the agitated lake surface caused by intemittent rock falls. Falling rocks are common since ...the lava lake level has dropped quickly, and exposed the walls. On May 6 the lake level was about 220 m (240 yards) below the crater rim and it continues to drop.
