In the late evening of November 27, 2022, an effusive eruption began inside Mokuʻāweoweo caldera at the summit of Mauna Loa volcano. Within a few hours, lava had covered most of the caldera floor, and several fissures just outside caldera sent short lava flows up to 3 kilometers (2 miles) to the southwest. Later in the morning of November 28, summit effusion ceased and the eruption moved into the volcano's Northeast Rift Zone. Several rift zone fissures were initially active, but by November 30 effusion had focused at a vent known as fissure 3. For another 10 days, fissure 3 fountained and fed lava flows that eventually stretched 18 kilometers (11 miles) to the north, threatening but not reaching the Daniel K. Inouye...

Alamagan Volcano is a Quaternary stratovolcano along the Mariana Arc, an active subduction zone in the western Pacific Ocean. Although primarily submerged, its peak reaches above sea level, with subaerially-exposed volcanic deposits dating back through the Holocene to the late Pleistocene. These feature data represent such deposits and other geologic features of Alamagan Volcano, describing its interpreted eruptive history.

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...
