This volcano is located on St. Vincent in the West Indies. It has a lake in its crater. Born in 1718, the volcano has had seven eruptions including violent eruptions in 1718, 1812, 1902, 1995, and 1997. A heavy ash fall accompanying the 1812 eruption killed 75 people. In 1902, the northern third of the island was devastated within several minutes by a glowing avalanche. The glowing ash cloud descended all sides of the volcano killing 1,600. Evacuation of 17,000 people in 1979 prevented a potential repeat of the tragedy of 1902. Large scale evacuations were ordered in 1997.

Following 39 years of inactivity, Crater Peak vent on the south flank of Mount Spurr volcano burst into eruption at 7:04 a.m. Alaska daylight time (ADT) on June 27, 1992. The Municipality of Anchorage reported nearly $2 million in damage, office closures, and cleanup costs from the August eruption. In addition, there were numerous, small-scale losses incurred by businesses. No loss of life resulted directly from the eruptions. However, two heart attacks, one fatal, from shoveling ashfall were reported in Anchorage.

The magnitude 8.6 (Mw) earthquake occurred south of the Andreanof Islands, in the Aleutian Islands. It generated an 8-meter tsunami that did great damage on Adak Island, especially to the fuel and oil docks. However, the Hawaiian Islands incurred the greatest damage (about $5 million in 1957 dollars). The highest wave was 10.4 meters at Haena, Kauai.

An earthquake occurred at 15 32 UT, only seconds before the explosion that began the eruption of Mount St. Helens volcano. This eruption and blast blew off the top of the volcano, reducing its elevation by 396 meters, killed 31 people and caused an estimated property damage of between $0.5 billion and $2 billion. About 53 earthquakes having magnitude larger than 4.5 were located near Mount St. Helens before the main event and eruption. No earthquakes having magnitudes higher than 4.5 were located following the eruption.

Photographs and other visual media provide valuable pre- and post-event data for natural hazards. Research, mitigation, and forecasting rely on visual data for post-analysis, inundation mapping and historic records. Instrumental data only reveal a portion of the whole story; photographs explicitly illustrate the physical and societal impacts from an event. This resource provides high-resolution geologic and damage photographs from natural hazards events, including earthquakes, tsunamis, slides, volcanic eruptions and geologic movement (faults, creep, subsidence and flows). The earliest images date back to 1867. Each event also links to NCEI's Global Historical hazards databases, which provide details for these events.

The 2021 North Atlantic Stepping Stones: New England and Corner Rise Seamounts expedition (EX-21-04) was a combined mapping and remotely operated vehicle (ROV) expedition to the seamounts of the Northwest Atlantic that took place between June 30 and July 29, 2021. Operations during this 30-day at sea expedition included a combination of ROV dives in support of NOAA Ocean Exploration and its partner priorities as well as exploratory mapping operations targeting areas containing no or poor quality modern mapping data. The initial focus was on the U.S. Northeast Seamount and high seas areas, however, during the expedition weather altered the planned transect to outside Bermudan waters where three dives took place before rejoining the planned dive sites exploring a total of 19 seamounts and one canyon (Hydrographer) for water column exploration. During the expedition, 20 Deep Discoverer ROV dives were conducted from 300 m to 4187 m water depth for a total of 154 hours of bottom time, and surveyed using EM 304 multibeam sonar 54,710 square km over 30 days at sea. All data associated with this expedition have been archived and are publicly available through the NOAA Archives.

This data set contains single channel seismic reflection profiles as provided to NGDC by Lamont Doherty Earh Observatory (LDEO). The profiles were originally provided as 8x10 negatives, but were scanned and now available as digital images. Images were scanned at 400 dpi using 8-bit grayscale and are in jpg format.

The basaltic shield volcano on the Island of Hawaii is among the most extensively studied volcanoes in the world. The volcano, with its summit caldera, is located on the east flank of giant Mauna Loa. Activity began with a violent explosive eruption in 1790. In the 19th and early 20th Centuries its lava lake eruptions attracted widespread attention. Nearly half of the world's known lava lake eruptions occur here.

Seismic creep is the constant or periodic movement on a fault as contrasted with the sudden rupture associated with an earthquake. It is a usually slow deformation of rock resulting from constant stress being applied over a period of time. Sometimes aseismic slip is observed at the ground surface along a ruptured fault that has produced a substantial earthquake. Examples are from the Hollister and Hayward, California, region. Several of the slides are split images of a location, comparing fault movement over the years.
