During a geologic emergency response, scientists can be integral to the response by distilling complex, technical information for decision-makers. As a scientist assigned to an emergency response and a member of an Incident Management Team (IMT), the scientist must understand their role and how they can help decision-makers make informed decisions.

Stephen has worked in landslide hazards since 2002, focusing primarily on landslide inventories, susceptibility and hazard analysis, remote sensing, outreach, and emergency response. His current role is the Associate Program Coordinator for Landslide Hazards, which supports the scientific direction and priorities of the Landslide Hazards Program. He also coordinates landslide technical response for domestic and international landslide disasters. Prior to the USGS, Stephen’s career has varied from consulting forest land managers on harvest-related landslides, working on emergency teams to assess post-wildfire debris flow hazards to downstream communities, consulting emergency managers on significant landslide events, developing and managing a landslide hazards program for the state of Washington, assisting developing countries seeking to improve their existing landslide programs, and producing educational material to help non-scientists understand landslide hazards.

External Grants Overview
The U.S. Geological Survey provides grants to local, state, territorial, and Tribal governments for risk communication, planning and coordination, mapping and assessments, and data collection of landslide hazards to develop information, knowledge, and methods that leads to the reduction of losses from landslides and increases public safety. - Data
Landslide Inventories across the United States version 2
Landslides are damaging and deadly, and they occur in every U.S. state. However, our current ability to understand landslide hazards at the national scale is limited, in part because spatial data on landslide occurrence across the U.S. varies greatly in quality, accessibility, and extent. Landslide inventories are typically collected and maintained by different agencies and institutions, usually wRapid Response Landslide Inventory for the 14 August 2021 M7.2 Nippes, Haiti, Earthquake
We present a preliminary point inventory of the landslides associated with the M7.2 Nippes, Haiti, earthquake that occurred on August 14, 2021. The mapping was part of rapid response efforts to identify hazards for situational awareness and emergency response by humanitarian aid organizations. This inventory accompanies an Open-File Report detailing the hazards presented by the landslides triggereField observations of ground failure triggered by the 2020 Puerto Rico earthquake sequence
This dataset consists of over 800 field observations of ground failure (landslides, lateral spreading, and liquefaction) and other damage triggered by the 2019-2020 Puerto Rico earthquake sequence. The sequence started with a M4.7 earthquake on 28 December 2019, followed by many more earthquakes, including 15 larger than M5 (as of 7 July 2020). The M6.4 mainshock, which is thought to have triggere - Multimedia

Learnings from rapid response efforts to remotely detect landslides triggered by the August 2021 Nippes earthquake and Tropical Storm Grace in Haiti
On August 14, 2021, a Mw 7.2 earthquake struck the Tiburon Peninsula of western Haiti triggering thousands of landslides. Three days after the earthquake on August 17, 2021, Tropical Storm Grace crossed shallow waters offshore of southern Haiti triggering more landslides worsening the situation.

Executive SummaryLandslide hazards are present in all 50 States and most U.S. territories, and they affect lives, property, infrastructure, and the environment. Landslides are the downslope movement of earth materials under the force of gravity. They can occur without any obvious trigger. Widespread or severe landslide events are often driven by such hazards as hurricanes, earthquakes, volcanicAuthorsJonathan W. Godt, Nathan J. Wood, Alice Pennaz, Connor M. Dacey, Benjamin B. Mirus, Lauren N. Schaefer, Stephen L. SlaughterLandslides triggered by the August 14, 2021, magnitude 7.2 Nippes, Haiti, earthquake
The August 14, 2021, magnitude 7.2 Nippes, Haiti, earthquake triggered thousands of landslides on the Tiburon Peninsula. The landslides directly caused fatalities and damage and impeded response efforts by blocking roads and causing other infrastructure damage. Adverse effects of the landslides likely will continue for months to years. This report presents an assessment of potential postearthquakeAuthorsSabrina N. Martinez, Kate E. Allstadt, Stephen L. Slaughter, Robert G. Schmitt, Elaine Collins, Lauren N. Schaefer, Sonia EllisonWhen hazard avoidance is not an option: Lessons learned from monitoring the postdisaster Oso landslide, USA
On 22 March 2014, a massive, catastrophic landslide occurred near Oso, Washington, USA, sweeping more than 1 km across the adjacent valley flats and killing 43 people. For the following 5 weeks, hundreds of workers engaged in an exhaustive search, rescue, and recovery effort directly in the landslide runout path. These workers could not avoid the risks posed by additional large-scale slope collapsAuthorsMark E. Reid, Jonathan W. Godt, Richard G LaHusen, Stephen L Slaughter, Thomas C. Badger, Brian D.

Detailed information about landslide occurrence is the foundation for advancing process understanding, susceptibility mapping, and risk reduction. Despite the recent revolution in digital elevation data and remote sensing technologies, landslide mapping remains resource intensive. Consequently, a modern, comprehensive map of landslide occurrence across the United States (USA) has not been compiledAuthorsBenjamin B. Mirus, Eric S. Jones, Rex L. Baum, Jonathan W.

The U.S. Pacific Northwest has a history of frequent and occasionally deadly landslides caused by various factors. Using a multivariate, machine-learning approach, we combined a Pacific Northwest Landslide Inventory with a 36-year gridded hydrologic dataset from the National Climate Assessment – Land Data Assimilation System to produce a landslide hazard indicator (LHI) on a daily 0.125-degree griAuthorsT.
