Researchers will reanalyze 2019 data from 400 instruments to identify small earthquakes and precisely locate...
- This $288,835 Project Grant from the National Science Foundation's Office of Integrative Activities will fund a collaborative research project titled "Arctic, Climate, and Earthquakes (ACE): Seismic Resilience and Adaptation of Arctic Infrastructure and Social Systems amid Changing Climate." The award will support research and education activities over a five-year period from January 2023 through December 2027. The project aims to improve understanding of how Arctic changes impact...
- The National Science Foundation Division of Earth Sciences awarded a $188,294 project grant to The University of New Mexico under the Geosciences federal grant program (CFDA 47.050) for the period of August 1, 2022 through July 31, 2024. The grant will support research to investigate structure and seismicity within the southern region of the 1964 Great Alaska earthquake rupture area using a dense node array. Specifically, the grantee will reanalyze seismic data collected in 2019 by 400...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $136,771 to support research characterizing the kinematics and dynamics of the Eastern Eurasian and Western North American Arctic regions. The principal investigators, Flesch and Elliott, will analyze GPS data to map current surface movements and develop computer models to understand the forces driving fault slip and earthquakes in this active tectonic area. The goal is to establish a...
- The National Science Foundation Office of Integrative Activities awarded Woods Hole Oceanographic Institution $428,486 on September 1, 2026, under the Geosciences program (CFDA 47.050) to establish relationships between tectonic features and seismic hazards at subduction zones. The research uses state-of-the-art plate tectonics models and mathematical methods to map connections between seafloor tectonic structures and earthquake locations at subduction zones, with initial focus on the Aleutians,...
- The National Science Foundation Division of Earth Sciences awarded the University of Hawaii at Manoa $193,833 for collaborative research on seismic monitoring and earthquake hazard assessment in the Eastern Aleutian Subduction Zone, with performance extending from January 1, 2027 through December 31, 2030. The award funds deployment of broadband ocean bottom seismographs in the Eastern Aleutian Subduction Zone, augmenting permanent land stations across a region transitioning from continental...
PROJECT TITLE: THE ERODING ICEBERG LAKE SEDIMENT: A SHORT-LIVED OPPORTUNITY TO OBTAIN A PALEOSEISMIC RECORD FROM THE EASTERN EDGE OF THE ALASKA SUBDUCTION ZONEPROJECT PERIOD: 3/1/2022 - 2/28/2023GEOLOGICAL RECORDS OF PAST EARTHQUAKES ARE OF KEY IMPORTANCE FOR SEISMIC HAZARD ASSESSMENTS. ON AND AROUND THE YAKUTAT TERRANCE SUCH PALEOSEISMIC RECORDS ARE SCARCE. CURRENTLY, ONLY COASTAL RECORDS EXIST WHICH PRESERVE EVIDENCE OF LAND-LEVEL CHANGE FROM MEGATHRUST EARTHQUAKES SUCH AS THE 1964 MW 9.2 PRINCE WILLIAM SOUND EARTHQUAKE. LAKES HAVE PROVEN TO PROVIDE VALUABLE ARCHIVES OF EARTHQUAKE SHAKING BY RECORDING DIFFERENT TYPES OF DEPOSITS TRIGGERED BY EARTHQUAKES. SUCH DEPOSITS HAVE ALLOWED TO ESTIMATE THE STRENGTH AND CHARACTERISTICS OF SEISMIC SKAHING. AND BY PROVIDING COMBINING SUCH RESULTS WITH SO-CALL GROUND-MOTION PREDICTION EQUATIONS (GMPES), IT IS SOMETIMES EVEN POSSIBLE TO ATTRIBUTE SPECIFIC SEISMIC SOURCES AND FAULT SEGMENTS TO PREHISTORIC EARTHQUAKES. HERE, WE STUDY ICEBERG LAKE, WHICH OFFERS A UNIQUE OPPORTUNITY TO OBTAIN PALEOSEISMIC RECORD FOR THE EASTERN EDGE OF THE ALASKAN-ALEUTIAN SUBDUCTION ZONE ENCOMPASSING THE LAST 1500 YEARS. WE WILL FIRST EXAMINE EXISTING DATASETS AND CORES FROM FIELDWORK EXECUTED BETWEEN 2001 AND 2003. NEXT WE PLAN FIELDWORK TO ICEBERG LAKE TO INVESTIGATE ADDITIONAL OUTCROPS WHICH WILL BE PROCEEDED BY CREATING A HIGH-RESOLUTION DIGITIL TERRANE MODEL TO GUIDE THE FIELDWORK EFFORTS. WE WILL THEN COMBINE DETAILED SEDIMENTOLOGICAL DESCRIPTIONS, PHOTOS, X-RAY COMPUTED TOMOGRAPHY (CT) SCANS, GRAIN-SIZE DATA AND OTHER PHYSICAL PARAMETERS TO IDENTIFY AND INTERPRET EARTHQUAKEINDUCED DEPOSITS. WE DATE THESE EVENT DEPOSITS BY COUNTING ANNUAL LAMINATIONS IN THE SEDIMENTS. FINALLY, WE WILL MERGE ALL GATHERED DATA AND CONSTRUCT A PALEOSEISMIC RECORD OF ICEBERG LAKE.LASTLY, WE WILL ASLO COLLECT SHEAR-WAVE VELOCITY (VS) PROFILES FROM BOTH CLAYER AND SANDY SEDIMENTS. THESE WILL BE USED TO MODEL HOW THESE SEDIMENTS WILL REACT TO DIFFERENT TYPES OF EARTHQUAKE SHAKING. USING THIS GROUND-MOTION MODELLING, WE AIM TO TURN THE ICEBERG LAKE PALEOSEISMIC RECORD INTO AN EXCEPTIONALLY QUALITATIVE AND QUANTITATIVE RECORD WHICH WILL REFINE LOCAL SEISMIC HAZARD ASSESSMENT AND PUSH THE BOUNDARIES OF LAKE PALEOSEISMOLOGY. LOCAL COMMUNITIES AND INTERNATIONAL LAKE PALEOSEISMIC COMMUNITIES WILL BENEFIT FROM THE RESULTS OF THIS PROJECT.
