What are the Effects of Earthquakes? | U.S. Geological Survey - USGS.gov
What are the Effects of Earthquakes? The effects from earthquakes include ground shaking, surface faulting, ground failure, and less commonly, tsunamis. Ground shaking is a term used to describe the vibration of the ground during an earthquake. Ground shaking is caused by body waves and surface waves.
Shaking, Damage and Failure | U.S. Geological Survey - USGS.gov
2022年11月21日 · In order to improve seismic hazard assessments, we need to advance our understanding of the physical processes that govern ground shaking and impacts, from the earthquake source that generates the ground shaking, along the path within the earth that distorts the motions, the surface effects of linear and non-linear attenuation and amplification ...
Earthquake Facts & Earthquake Fantasy | U.S. Geological Survey - USGS.gov
An earthquake is the ground shaking caused by a sudden slip on a fault. Stresses in the earth's outer layer push the sides of the fault together. Stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the earth's crust and cause the shaking that we feel during an earthquake.
Effects of Earthquakes - University of California, San Diego
Ground shaking is the most familiar effect of earthquakes. It is a result of the passage of seismic waves through the ground, and ranges from quite gentle in small earthquakes to incredibly violent in large earthquakes. In the 27 March 1964 Alaskan earthquake, for example, strong ground shaking lasted for as much as 7 minutes!
What Are Earthquake Hazards? | UPSeis | Michigan Tech
The second main earthquake hazard is ground displacement (ground movement) along a fault. If a structure (a building, road, etc.) is built across a fault, the ground displacement during an earthquake could seriously damage or rip apart that structure.

2024年12月30日 · For example, the 1985 Michoacan (Mexico) M8.0 earthquake caused strong ground motions leading to serious damage to the Mexico City situated at about 400 km distance from the earthquake epicentre ...
Earthquake losses due to ground failure - ScienceDirect
2004年10月1日 · The focus of this study is to understand the relative impact of ground failure on earthquake damage and losses. As such, invaluable field data includes the mapping of ground failure occurrence, alongside the mapping of structural damage and lifeline damage.
Ground Shaking (Earthquake) | UNDRR
Ground shaking is the predominant seismic hazard (secondary seismic hazards include liquefaction, surface rupture, landslides etc.), causing more than 90% of earthquake damage and losses (National Institute of Building Sciences Building Seismic Safety Council, 2010).

11.4 The Impacts of Earthquakes – Physical Geology
Ground shaking during an earthquake can be enough to weaken rock and unconsolidated materials to the point of failure, but in many cases the shaking also contributes to a process known as liquefaction, in which an otherwise solid body of sediment is transformed into a liquid mass that can flow.
