Lava from fissure 8 is entering the sea this morning on the southern portion of the flow front primarily through the open channel, but also along this 1 km (0.6 mi) wide area with multiple laze plumes from smaller oozing lobes.

Recent explosive events haven't produced significant ash plumes from the summit, but downwind communities may still experience ashfall when previously erupted ash is remobilized.

Lower Tubbs Island is a tidal marsh near Midshipman Point in northern San Pablo Bay, California, and is part of the San Pablo Bay National Wildlife Refuge. Historically, Tubbs Island was used as a club for duck hunters, protected by levees that could be opened with the tides to release salt water into the sloughs. In 1969, it was purchased by the Natu

USGS scientists Kim Besiner, John Solder and Kate Wilkins collect groundwater samples at Grapevine Main Spring. 

Scientists traveled to the remote locations along the south rim of the Grand Canyon to assess the potential effects of mining along the Coconino Plateau and groundwater withdrawals associated with increasing populations.

USGS scientist Joel Unema hikes to National Canyon Spring to collect groundwater samples from a remote location near the south rim of the Grand Canyon. Joel Unema was part of a group of USGS and National Park Service scientists that rafted 150 miles in nine days to better understand natural resources.

USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).

This panorama of Kīlauea's summit caldera was made about 10 a.m. HST from the Keanakāko‘i overlook on the south side of the caldera. Halema‘uma‘u is visible steaming to the left, and the ongoing ground cracking is visible in the center of the image.

On June 23, 2018 at 4:32 p.m. HST after approximately 17 hours of elevated seismicity, a collapse explosion occurred at the summit if Kīlauea. The energy released by the event was equivalent to a magnitude 5.3 earthquake.

This animated GIF shows a timelapse sequence consisting of one image per day between June 13 and 24. The photos were taken from the southern caldera rim, near Keanakāko‘i Crater, and look north towards HVO and Jaggar Museum.

At fissure 8, fountains provide a vigorous supply of lava that exits the cinder cone and drops over a spillway to enter a well-established lava channel that extends to the sea.
