Peter J Haeussler, Ph.D.
Most of my research is related to earthquake and tsunami hazards in Alaska, with a focus on paleoseismology, submarine landslides, and active faulting. I am the Alaska Coordinator for the Earthquake Hazards Program of the USGS. I also study various aspects of the framework geology of Alaska, with a focus on neotectonics and tectonics.
I use various tools to understand earthquakes and earthquake hazards in Alaska. I’ve studied the tectonic evolution of parts of Alaska, accretionary prisms along Alaska’s margin, forearc and splay faulting, submarine landslides, mountain building and exhumation, landscape evolution, glacial histories, and sedimentary basins. I’ve worked with marine and terrestrial seismic reflection and potential field data. Current work is focused on lacustrine paleoseismology, splay faulting, and various seismic hazards projects.

Simulated inundation extent and depth at Whittier, Alaska resulting from the hypothetical rapid motion of landslides into Barry Arm Fjord, Prince William Sound, Alaska
This data release contains postprocessed model output from simulations of hypothetical rapid motion of landslides, subsequent wave generation, and wave propagation. A modeled tsunami wave was generated by rapid motion of unstable material into Barry Arm Fjord. This wave propagated through Prince William Sound and then into Passage Canal east of Whittier. Here we consider only the largest...

Eastern Denali Fault Surface Trace Map, Eastern Alaska and Adjacent Canada, 1978-2008
The eastern section of the Denali Fault did not rupture during the 2002 Denali Fault earthquake (Mw 7.9), however seismologic, geodetic, and geomorphic evidence along with a paleoseismic record of several past ground-rupturing earthquakes demonstrate the fault is active. Thick vegetation, along with complex glacial landforms, large braided rivers, and fault-parallel bedrock structure (e...

Cretaceous to Oligocene magmatic and tectonic evolution of the western Alaska Range: Insights from U-Pb and 40Ar/39Ar geochronology
New U-Pb and 40Ar/39Ar ages integrated with geologic mapping and observations across the western Alaska Range constrain the distribution and tectonic setting of Cretaceous to Oligocene magmatism along an evolving accretionary plate margin in south-central Alaska. These rocks were emplaced across basement domains that include Neoproterozoic to Jurassic carbonate and siliciclastic strata...

Detection and assessment of a large and potentially tsunamigenic periglacial landslide in Barry Arm, Alaska
The retreat of glaciers in response to global warming has the potential to trigger landslides in glaciated regions around the globe. Landslides that enter fjords or lakes can cause tsunamis, which endanger people and infrastructure far from the landslide itself. Here we document the ongoing movement of an unstable slope (total volume of 455 million m3) in Barry Arm, a fjord in Prince...

Submarine landslide kinematics derived from high-resolution imaging in Port Valdez, Alaska
Submarine landslides caused by strong ground shaking during the M9.2 1964 Great Alaska earthquake generated a tsunami that destroyed much of the old town of Valdez, Alaska, and was responsible for 32 deaths at that location. We explore structural details of the 1964 landslide deposit, as well as landslide deposits from earlier events, in order to characterize kinematics of the landslide...

Evidence for large Holocene earthquakes along the Denali fault in southwest Yukon, Canada
The Yukon–Alaska Highway corridor in southern Yukon is subject to geohazards ranging from landslides to floods and earthquakes on faults in the St. Elias Mountains and Shakwak Valley.

Sediment sources and transport by the Kahiltna Glacier and other catchments along the south side of the Alaska Range, Alaska
Erosion related to glacial activity produces enormous amounts of sediment. However, sediment mobilization in glacial systems is extremely complex. Sediment is derived from headwalls, slopes along the margins of glaciers, and basal erosion; however, the rates and relative contributions of each are unknown. To test and quantify conceptual models for sediment generation and transport in a...

Turbidite stratigraphy in proglacial lakes: Deciphering trigger mechanisms using a statistical approach
Turbidites embedded in lacustrine sediment sequences are commonly used to reconstruct regional flood or earthquake histories. A critical step for this method to be successful is that turbidites and their trigger mechanisms are determined unambiguously. The latter is particularly challenging for prehistoric proglacial lake records in high-seismicity settings where both earthquake...

The sedimentary record of the 2018 Anchorage Earthquake in Eklutna Lake, Alaska: Calibrating the lacustrine seismograph
The 30 November 2018 Mw 7.1 Anchorage earthquake caused modified Mercalli intensities of V¼ to V½ at Eklutna Lake (south central Alaska). A few hours after the earthquake, a “dirt streak” was observed on the lake surface, followed by a peak in sediment turbidity values (∼80 times normal) at a drinking water facility, which receives water from the lake through a pipe. These observations...

Detrital zircon geochronology along a structural transect across the Kahiltna assemblage in the western Alaska Range: Implications for emplacement of the Alexander-Wrangellia-Peninsular terrane against North America
The Kahiltna assemblage in the western Alaska Range consists of deformed Upper Jurassic and Cretaceous clastic strata that lie between the Alexander-Wrangellia-Peninsular (AWP) terrane to the south, and the Farewell and other peri-cratonic terranes to the north. Differences in detrital zircon populations and sandstone petrography allow geographic separation of the strata into two...
