Close up of Sheet 2 of "Lava inundation zone maps for Mauna Loa, Island of Hawai‘i," recently published by the U.S. Geological Survey. Colors depict lava Inundation zones for the Kaumana, Waiākea, and Volcano-Mountain View regions on Mauna Loa. Yellow indicates the volcano's Northeast Rift Zone, one area along which lava could erupt.

The lava lake within Halema‘uma‘u, a crater at the summit of Kīlauea, was about 30 m (98 ft) below the vent rim on the day of this photo (January 7, 2016).

In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.

Scattered breakouts today (October 13) on the western 61g flow margin were mapped at 1.3 km (0.8 mi) from the closest portion of the emergency road. The small pāhoehoe breakouts put on a show as they slowly oozed out of growing cracks that were forced open by flow inflation (pictured).

This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of September 21 is shown in pink, while widening and advancement of the active flow as of October 12 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray. The yellow line is the trace of the active lava tube.

Today (October 12), the Kamokuna lava delta was measured at roughly 11 acres (4.5 hectares) in size. Over the past two months, several lava tube breakouts on the sea cliff have spilled lava onto the delta.

HVO geologists relocate a time-lapse camera on the rim of the west pit lava pond in the Pu‘u ‘Ō‘ō crater. Over the past several months, the camera has been slowly tilting downward due to soft, altered ground beneath it, and the general instability of the rim. The new location, about 20 m (yards) to the south, appears to be more stable and less altered.

Josh Logan, a physical scientist at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California, operates an unmanned aerial system, or UAS, often called a "drone", that is equipped with a video camera.
