Digging Up Evidence Of Past Earthquakes In Salt Lake Valley Utah

Digging Up Evidence Of Past Earthquakes In Salt Lake Valley Utah To study past earthquakes, geologists conduct paleoseismic (ancient earthquake) studies by excavating trenches across fault scarps and studying and dating the geologic deposits in the excavation to determine past earthquake timing. Two recent paleoseismic (ancient earthquake) studies of the wasatch fault zone were conducted to investigate the history of past fault ruptures within salt lake and utah valleys.

Digging Up Evidence Of Past Earthquakes In Salt Lake Valley Utah "these are indicating where geologists see evidence of past earthquakes that have ruptured the surface," kleber said, showing a map of the salt lake valley with color coded lines. We document evidence for six paleoearthquakes (al6–al1) from scarp‐derived colluvial wedges and crosscutting relations. a ground‐penetrating radar survey across the scarp resolved fault‐zone width, but not paleoearthquake stratigraphy. With usu geosciences associate professor alexis ault and doctoral student jordan jensen, shreedharan has published new findings about why earthquakes occur along the wasatch fault and why communities along the fault are more vulnerable to earthquake damage than previously thought. This study presents a new velocity model for the salt lake basin (slb) in utah, determined using data from permanent and temporary seismic stations located on top of the basin in the salt lake valley (slv) and nearby.

Also shown is a model of a 50° dipping planar fault for the salt lake city segment. the color version of this figure is available only in the electronic edition. To develop a comprehensive holocene chronology of surface faulting earthquakes on the slc segment, the utah geological survey reoccupied the sfdc site to complete the investigation started there in 1985. Researchers explain why properties of fault rocks and geologic events that occurred more than a billion years ago portend worrisome seismic activity for utah's population center. Moschetti and his team compiled a database of ground motion recordings from 59 earthquakes since 2010 — nearly half of which came from the magna earthquake sequence — and identified regional features affecting earthquake hazards.
