Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...
Earthquake-triggered landslides and liquefaction, collectively referred to as ground failure, can be a significant contributor to earthquake losses. [3] The USGS Ground Failure (GF) earthquake product provides near-real-time spatial estimates of earthquake-triggered landslide and liquefaction hazard following significant earthquakes worldwide.
Studies of liquefaction features left by prehistoric earthquakes, called paleoliquefaction or paleoseismology, can reveal information about earthquakes that occurred before records were kept or accurate measurements could be taken. [21] Soil liquefaction induced by earthquake shaking is a major contributor to urban seismic risk.
A strong earthquake on the Wasatch Fault could trigger landslides, cause mass liquefaction, and flooding of low-lying areas forming near lakes due to subsidence and tilting. The quake may also rupture the surface causing displacement of up to 20 feet (6.1 m), and severely damage gas, electric, water, communication, and transportation lifelines. [9]
What causes earthquakes? Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other.
Since March 5, 11 earthquakes have occurred in the commonwealth, with ten below a 2.0 magnitude. The most recent earthquake over a 3.0 magnitude was on May 29, 2023 near Calhoun in McLean County.
These earthquakes also caused the largest known sand boil in the world, which can still be found near Hayti, Missouri and is locally called "The Beach". [4] It is 2.3 kilometers long and covers 55 hectares. In the past few years, much effort has gone into the mapping of liquefaction features to study ancient earthquakes. [5]
It came on the heels of two other earthquakes on June 7 in the same area near the city of Buford — a 2.5 magnitude quake and another of 2.1 magnitude, which shook the area a few hours earlier ...
