The Smithsonian's Global Volcanism Program seeks better understanding of all volcanoes through documenting their eruptions small as well as large during the past 10,000 years. Search our database to find volcanoes from around the world.

Welcome to the South Pacific Odyssey, a scientific quest to understand a part of the deep sea called the Lau Basin. Enveloped by the territorial waters of the Kingdom of Tonga, the journey to the Lau Basinrich in mystery and intrigueseeks answers to questions, simple and complex: What forces shape the dramatic landscapes that characterize this ocean basin? Why is the seafloor here different from any other place on Earth? What bizarre life forms exist at these deep-sea hot springs? How can life exist in such extreme conditions, and what can we learn from it? Throughout this site, you will explore the Lau Basin; meet the scientists; catch glimpses of the rich culture, customs and traditions of the people of this region; and journey alongside as scientists lock their sights on a target spot. Only then will they begin to unravel the mysteries, one by one, map by map, rock by rock, animal by animal.

SCCOOS brings together coastal observations along the Southern California Bight to provide information necessary to address issues in coastal water quality, marine life resources, and coastal hazards.
Working interactively with local, state and federal agencies, resource managers, policy makers, educators, scientists and the general public, SCCOOS will improve our understanding and delivery of coastal observations, and will allow us to better manage our coastal ocean environment. Access realtime and archived SCCOOS data collected within the Southern California Bight (SCB). Find related data products, information on metadata, database schema and data flow charts. SCCOOS modeling efforts include ROMS-based Integrated Modeling of the Southern California Coastal Ocean, Coastal Ocean Data Assimilation System (CODAS), ocean swell propagation modeling, sediment transport modeling, and wind-wave generation modeling. OurOcean Portal provides access to many of these products.

Through hundreds of research projects, the Earth Institute brings its strengths from climate prediction to integrated water management, biodiversity conservation to public health, geophysics to hazards reduction to bear on the challenges of environmental decision-making, international development programs, and science policy to greatly improve conditions for the world's poor while preserving the natural systems that support life on Earth.

This site is a resource for anyone interested in paleontology, from the professional in the lab to the interested amateur scouting for fossils to the student in any classroom. We have gathered many different resources into this single entry "portal" to paleontological information on the Internet. Images and links that you see as you browse through the site have been reviewed and selected for quality by one or more members of the Editorial Board. This site was produced by the University of California Museum of Paleontology, the Paleontological Society, the Society of Vertebrate Paleontology, and the United States Geological Survey. The site was funded by the National Science Foundation.

The TRC is actively involved with all aspects of tsunami research; inundation field surveys, numerical and analytical modeling, and hazard assessment, mitigation and planning.
The TRC has developed the tsunami inundation maps for California and the tsunami code MOST, now used by NOAA. MOST is the only validated code used in the US for tsunami hazard mapping with detailed inundation predictions. TRC faculty and students have surveyed all except one of the "modern" tsunamis since 1992, and have been working on meta-tsunami surveys for the 1946 Aleutian and 1956 Amorgos, Greece events. The TRC is a unit of the Department of Civil Engineering.

The UNAVCO Facility in Boulder, Colorado is the primary operational activity of the UNAVCO community. It exists to support university and other research investigators using the Global Positioning System (GPS) for Earth sciences research.

The USGS serves the Nation by providing reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.

The U.S. National Ocean Bottom Seismograph Instrument Pool provides instrumentation to support research to further our understanding of marine geology, seismology, and geodynamics. Funded through the NSF, the Pool makes ocean bottom seismic equipment available to all interested researchers, to private and public organizations, and to industry.

The mission of ANSS is to provide accurate and timely data and information products for seismic events in the United States, including their effects on buildings and structures, employing modern monitoring methods and technologies. ANSS will establish nationwide network of over 7000 earthquake sensor systems, serving all areas of the country subject to earthquake hazards and providing dense coverage in 26 at-risk urban areas (see map). Sensors will be located both in the ground and in buildings and other structures. The system will provide real-time earthquake information for emergency response personnel, provide engineers with information about building and site response to strong shaking, and provide scientists with high-quality data needed to understand earthquake processes and structure and dynamics of the solid earth.

The Hawaiian Volcano Observatory (HVO) enjoys a world-wide reputation as a leader in the study of active volcanism. Due to their usually benign natures, Kilauea and Mauna Loa, the most active volcanoes on the Island of Hawai`i, can be studied up close in relative safety. While observations made by 19th-century missionaries and travelers constitute a large part of the early and colorful history of volcano watching in Hawai`i, HVO's origins are rooted in a desire to use scientific methodology to understand the nature of volcanic processes and to reduce their risks to society.
