The Integrated Feasibility Report and Environmental Assessment (IFR/EA) is a study led by the Honolulu District of the Pacific Ocean Division of USACE, with the American Samoa Government as the non-Federal sponsor. It focuses on addressing flood risk in the Tafuna-Leone Plain of Tutuila Island, which is densely populated and vulnerable to frequent flooding due to heavy rainfall, shallow stream channels, and various development-related factors.
This Watershed Assessment (WA) was initiated in response to the damage caused by Tropical Cyclone Gita in February 2018, which led to infrastructure damage, power outages, and widespread flooding in American Samoa. The assessment recognizes the resilience of Pacific Islanders' cultures and traditional governance and aims to provide recommendations, both within and outside of USACE authorities, to enhance the resilience of American Samoa to future natural hazards.

This report presents findings from the analysis of radiocarbon dates and volcanic stratigraphy in the Leone Volcanics region of Tutuila Island, American Samoa, shedding light on the timing and spatial distribution of late-Holocene volcanic events. Key insights include identifying a distinct reddish ash stratum dating to approximately AD 650-750 as the most recent eruptive event, along with observations on the source and sequence of ash deposits, suggesting multiple eruptive events from both seaward and inland craters, potentially continuing as recently as AD 1300.
This paper presents over 100 radiocarbon dating results for Tutuila and Manu'a in American Samoa, contributing to various aspects of Samoan archaeology.
This paper delves into the agriculture and livestock use in American Samoa.
This map shows the different geology present on Tutuila, American Samoa. Scale approximately 1:60,000. 39 x 86 cm. "Contour interval on land, 200 feet. Soundings in fathoms." Shows diagrammatic structure sections, sedimentary and volcanic rocks, and great erosional unconformity.

Climate change profoundly affects global agriculture, posing food security threats via extreme weather, temperature shifts, and rainfall variations. In the Pacific Islands, additional challenges like sea-level rise and ecosystem degradation exacerbate these issues. The American Samoa Extension Climate Forum, conducted on June 20-21, 2018, sought to address these concerns by engaging stakeholders in discussions about sustainable agriculture, climate adaptation, and food security.
Pacific Island Developing Countries (PIDCs) contribute a minuscule 0.03 percent to global carbon dioxide emissions, with residents producing only a quarter of the world's average emissions per person. However, despite their minimal emissions, these nations are expected to face some of the earliest and harshest consequences of climate change, with a particular focus on its impact on freshwater resources. This chapter delves into the potential threats posed by climate change to the already stressed freshwater supplies in PIDCs.
In response to climate change impacts like rising sea levels, efforts are being made in the Pacific Islands region to assess and adapt to the effects on mangroves. This includes improving management practices, reducing stress on mangroves, and integrating climate data into land-use planning to minimize risks to coastal ecosystems and human safety.
This chapter discusses advances in climate change impact, adaptation, and vulnerability assessment methods, emphasizing the growing use of risk management frameworks, stakeholder involvement, and diverse scenario approaches. These developments aim to provide policy-relevant information for effective decision-making in the face of climate change, recognizing the importance of considering non-climate factors and regional-scale scenarios.
This chapter explores the complex interactions within the climate system, emphasizing the significance of understanding climate's physical and social impacts at various scales. It underscores the importance of assessing vulnerability to climate conditions, focusing on sensitivity, exposure, and resilience, especially in Pacific Island communities facing climate-related challenges.
This report, part of the Pacific Islands Regional Climate Assessment (PIRCA), discusses climate change indicators and their impacts on key sectors in American Samoa. PIRCA, a collaborative effort involving various stakeholders, aims to inform and prioritize actions in response to climate change in the US-Affiliated Pacific Islands and the Hawaiian archipelago.
This project focuses on assessing American Samoa's vulnerability to natural hazards and the impacts of climate change. It engaged with the community through an online survey, interviews, and a preparedness workshop in Pago Pago. The goal is to help residents and professionals in American Samoa prepare for future hazard events and climate change impacts, providing information, stories, and guidance on disaster and climate change preparedness
Following the 2009 Samoa-Tonga earthquake, the Samoan islands, including Savai'i, Upolu, and Tutuila, have experienced accelerated sea-level rise, driven by subsidence and gravity changes, with American Samoa witnessing a 5 times faster rate than the global average. A viscoelastic model predicts a continued sea-level rise of 30-40 cm, intensifying coastal flooding.
