After 100 years of restricted tidal activity to support agricultural use and salt harvesting, the tidal marshes around San Francisco Bay, like this one at Bair Island, are steadily rebuilding, returning to a stunning mosaic of marsh, mudflat, and channels.

A UAS mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit.

Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west.

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. On authorized permission from Hawai‘i Volcanoes National Park, our Unmanned Aircraft Systems crew is conducting gas measurements at Pu‘u ‘Ō‘ō.

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
