Geospatial database of the 2022 summit and Northeast Rift Zone eruption of Mauna Loa volcano, Hawai'i
In the late evening of November 27, 2022, an effusive eruption began inside Moku'aweoweo 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

Newberry Volcano's youngest lava flows
Most of Newberry Volcano's youngest lava flows are found within the Newberry National Volcanic Monument in central Oregon. Established November 5, 1990, the monument is managed by the U.S. Forest Service as part of the Deschutes National Forest.

Under trees and water at Crater Lake National Park, Oregon
Crater Lake partially fills the caldera that formed approximately 7,700 years ago during the eruption of a 12,000-ft-high volcano known as Mount Mazama. The caldera-forming, or climactic, eruption of Mount Mazama devastated the surrounding landscape, left a thick deposit of pumice and ash in adjacent valleys, and spread a blanket of volcanic ash as far away as southern Canada. Prior to the climact
Maps of Hawaiian Islands exclusive economic zone interpreted from GLORIA sidescan-sonar imagery
The map is geology around the Hawaiian Islands derived from GLORIA data collected in 1986-1989 from the southeastern Hawaiian Ridge EEZ (Exclusive Economic Zone), which covers more than 1,000,000 km2 of sea floor. The seafloor is characterized by a variety of volcanic and sedimentary processes. Cretaceous age seafloor underlies both subaerial and subaqueous erupted lava forming the Hawaiian Ridge
Hawaii's volcanoes revealed
Hawaiian volcanoes typically evolve in four stages as volcanism waxes and wanes: (1) early alkalic, when volcanism originates on the deep sea floor; (2) shield, when roughly 95 percent of a volcano's volume is emplaced; (3) post-shield alkalic, when small-volume eruptions build scattered cones that thinly cap the shield-stage lavas; and (4) rejuvenated, when lavas of distinct chemistry erupt follo

Around 500,000 people each year visit Crater Lake National Park in the Cascade Range of southern Oregon. Volcanic peaks, evergreen forests, and Crater Lake’s incredibly blue water are the park’s main attractions. Crater Lake partially fills the caldera that formed approximately 7,700 years ago by the eruption and subsequent collapse of a 12,000-foot volcano called Mount Mazama. The caldera-forming

Postglacial faulting near Crater Lake, Oregon, and its possible association with the Mazama caldera-forming eruption
Volcanoes of subduction-related magmatic arcs occur in a variety of crustal tectonic regimes, including where active faults indicate arc-normal extension. The Cascades arc volcano Mount Mazama overlaps on its west an ∼10-km-wide zone of ∼north-south–trending normal faults.

Surface morphology of caldera-forming eruption deposits revealed by lidar mapping of Crater Lake National Park, Oregon- Implications for emplacement and surface modification
Large explosive eruptions of silicic magma can produce widespread pumice fall, extensive ignimbrite sheets, and collapse calderas. The surfaces of voluminous ignimbrites are rarely preserved or documented because most terrestrial examples are heavily vegetated, or severely modified by post-depositional processes. Much research addresses the internal sedimentary characteristics, flow processes, and

Lahar hazard zones for eruption-generated lahars in the Lassen Volcanic Center, California
Lahar deposits are found in drainages that head on or near Lassen Peak in northern California, demonstrating that these valleys are susceptible to future lahars. In general, lahars are uncommon in the Lassen region. Lassen Peak's lack of large perennial snowfields and glaciers limits its potential for lahar development, with the winter snowpack being the largest source of water for lahar generatio

Volcano hazards assessment for the Lassen region, northern California
The Lassen region of the southernmost Cascade Range is an active volcanic area. At least 70 eruptions have occurred in the past 100,000 years, including 3 in the past 1,000 years, most recently in 1915. The record of past eruptions and the present state of the underlying magmatic and hydrothermal systems make it clear that future eruptions within the Lassen Volcanic Center are very likely. Althoug
