The right side of the figure is an image of a small piece of the Y-9 core from the USGS 1967-68 drilling expedition to Yellowstone National Park. The black area was analyzed using a scanning electron microscope (SEM) at the University of Wyoming to determine mineralogy and dispersion of elements.

KWcam webcam image from December 2 at 6:00 p.m. HST, immediately following a M3.1 earthquake at Kīlauea summit. Several rockfalls down the talus slope impacted the summit water lake, causing some brief localized color changes of the lake surface (circled in yellow).

ANIMATED GIF: At Kīlauea summit, the KWcam webcam recorded several small color changes along the lake margin following rockfalls which impacted the lake surface. These rockfalls immediately followed a M3.1 earthquake Wednesday evening, December 2, at 5:59 p.m. HST. This animated image file (GIF) continuously loops two consecutive webcam images from 5:50 p.m.

Tephra layers preserved at the summit of Kīlauea from at least three different eruptions. Deposits below the top of the scale are predominantly juvenile and deposits above it containing many lithics. Notice the larger size of the yellow pumice clasts compared to the much denser and finer grey lapilli and ash surrounding them from 7 to 18 on the scale.

Dark brown colors dominated the central and western portions of the lake at Kīlauea's summit. The greenish hues were present in areas that appear to be zone of hot water influx into the lake. USGS photo by M. Patrick.

A quick visit to the western caldera rim provided brief views of Kīlauea's summit lake between rain showers. The lake colors were particularly vibrant today, with a deep blue-green color in the western end (bottom of photo), with dark brown near the center. USGS photo by M. Patrick.
