alex grant
alex is a Research Engineer specializing in regional-scale landslide and liquefaction hazards and risk
Biography
alex got his Ph.D. in 2017 from the University of Washington where he studied coseismic landslide hazard and risk in Lebanon, New Zealand, Japan, and the Pacific Northwest of N. America. alex received his BSCE from Tufts University in 2013 and a MSE in 2014 from the University of Washington in Geotechnical Engineering. alex joined the USGS in 2018 to research earthquake-induced ground failures, and is actively working on projects in the Pacific Northwest and California.
Science and Products
Ground failure triggered by shaking during the November 30, 2018, magnitude 7.1 Anchorage, Alaska, earthquake
We developed an initial inventory of ground failure features from the November 30, 2018, magnitude 7.1 Anchorage earthquake. This inventory of 153 features is from ground-based observations soon after the earthquake (December 5–10) that include the presence or absence of liquefaction, landslides, and individual crack traces of lateral spreads and...

Probabilistic regional-scale liquefaction triggering modeling using 3D Gaussian processes
Liquefaction is a major cause of coseismic damages, occurring irregularly over hundreds or thousands of square kilometers in large earthquakes. Large variations in the extent and location of liquefaction have been observed in recent earthquakes, motivating the need for prediction methods that consider the spatial heterogeneity of geologic deposits...
Greenfield, Michael; Grant, Alex R. R. USGS near-real-time products-and their use-for the 2018 Anchorage earthquake
In the minutes to hours after a major earthquake, such as the recent 2018 Mw">Mw 7.1 Anchorage event, the U.S. Geological Survey (USGS) produces a suite of interconnected earthquake products that provides diverse information ranging from basic earthquake source parameters to loss estimates. The 2018 Anchorage earthquake is the first...

Seismological, geological, and geotechnical engineering aspects of the 2018 MW 6.6 Hokkaido Eastern Iburi earthquake
The 2018 Hokkaido Eastern Iburi MW6.6 earthquake struck the southern coast of the north island of Japan in the early morning (3:08 AM JST) on September 6, 2018. The event had a hypocentral depth of 35 km, centered beneath the port city of Tomakomai. Extremely strong shaking with peak ground acceleration in excess of 0.5 g was felt in the...
