Results of ongoing multi-year research on induced earthquakes by the United States Geological Survey (USGS) published in 2015 suggested that most of the significant earthquakes in Oklahoma, such as the 1952 magnitude 5.7 El Reno earthquake may have been induced by deep injection of waste water by the oil industry. "Earthquake rates have ...
A landslide in which the sliding surface is located within the soil mantle or weathered bedrock (typically to a depth from few decimeters to some meters) is called a shallow landslide. Debris slides and debris flows are usually shallow. Shallow landslides can often happen in areas that have slopes with high permeable soils on top of low ...
The most abundant types of earthquake-induced landslides are rock falls and slides of rock fragments that form on steep slopes. However, almost every other type of landslide is possible, including highly disaggregated and fast-moving falls; more coherent and slower-moving slumps, block slides, and earth slides; and lateral spreads and flows ...
Coseismic liquefaction induced by one of the 2012 Emilia, Northern Italy, earthquakes. Secondary effects: mostly this is the intensity of the ground shaking (e.g., landslides, liquefaction, etc.). The importance of a tool to measure earthquake Intensity was already outlined early in the 1990s. [2]
The term ground failure is a general reference to landslides, liquefaction, lateral spreads, and any other consequence of shaking that affects the stability of the ground. This usually takes place as an after-effect of an earthquake, and is one of the major causes of destruction after an earthquake. Ground failures tend to happen almost every ...
Two strong earthquakes struck off Cuba’s coast Sunday, damaging homes and infrastructure and triggering landslides just as the country was in the middle of cleanup efforts following the landfall ...
A landslide that began in 1956 destroyed 140 homes in the Portuguese Bend area of the city of Rancho Palos Verdes, and earth continues to move there. ... Human-induced landslide factors include ...
Mitigation of seismic motion is an important factor in earthquake engineering and construction in earthquake-prone areas.The destabilizing action of an earthquake on constructions may be direct (seismic motion of the ground) or indirect (earthquake-induced landslides, liquefaction of the foundation soils and waves of tsunami).
