Any buildings in the path of these surface waves can lean or tip over from all the movement. The ground shaking may also
cause landslides, mudslides
, and avalanches on steeper hills or mountains, all of which can damage buildings and hurt people.
What are the effects of ground shaking in your home?
The contents of your home may be damaged and can be dangerous:
Shaking can make light fixtures fall, refrigerators and other large items move across the floor
, and bookcases and television sets topple over. IDENTIFY: Look around your house for things that could fall or move.
Who would be affected by ground shaking?
Most earthquake damage results from the shaking caused by seismic waves passing beneath
buildings, roads
, and other structures. For example, ground shaking may cause a store’s exterior building walls to crumble, injuring people, blocking sidewalks and streets and bringing down utility lines.
What are the hazards of ground shaking?
Ground Shaking
If an earthquake generates a large enough shaking intensity,
structures like buildings, bridges and dams can be severley damaged, and cliffs and sloping ground destabilised
. Perched or stacked objects may fall and injure or bury anyone close by.
What are the effects of earthquake to human life?
Earthquakes sometimes
trigger tsunamis, landslides and occasionally volcanic activity
. Earthquakes impact on food security and agriculture-based livelihoods through: loss and injury of family members and workforce. loss of crop yields and livestock.
How can the effects of ground shaking be reduced?
We cannot prevent natural earthquakes from occurring but we can significantly mitigate their effects by
identifying hazards
, building safer structures, and providing education on earthquake safety. By preparing for natural earthquakes we can also reduce the risk from human induced earthquakes.
How do you stop ground shaking?
Drop to the floor, take cover under a sturdy table or desk against an inside wall. Grasp one of its legs while covering your head with your other arm. Outside a building: Move into a clearing and away from power lines, trees and buildings.
Drop to the ground and wait for the shaking
to stop.
What is ground shaking in your own words?
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. As a generalization, the severity of ground shaking increases as magnitude increases and decreases as distance from the causative fault increases.
What does it mean when the ground starts shaking?
Earthquakes
are violent shaking from the planet’s surface, according to AccuWeather. They’re caused by movement from Earth’s outermost layer, the crust. … That sudden release leads to an earthquake. The shaking begins at a central region called the epicenter and spreads far and wide.
What causes the ground to shake so strongly?
Earthquakes
are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.
What type of ground material shakes the most?
Soft soils such as sand
tend to amplify the shaking compared with hard soils such as bedrock. In addition to being soft, sand can also undergo a “liquefaction process” during an earthquake. This means the sand can change from behaving like a solid to behaving like a thick liquid, which further amplifies shaking.
Is ground shaking a geological hazard?
| Geologic Event Hazards They Cause | Earthquake A. Ground shaking | B. Surface faulting | C. Landslides and liquefaction | 1. Rock avalanches |

What are the 10 causes of earthquake?
- Groundwater extraction – decrease in pore pressure.
- Groundwater – increase in pore pressure.
- Heavy rain.
- Pore fluid flow.
- High CO2 pressure.
- Building dams.
- Earthquakes.
- No earthquakes (Seismic quiescence)
What are the 10 effects of earthquake?
The primary effects of earthquakes are
ground shaking, ground rupture, landslides, tsunamis, and liquefaction
. Fires are probably the single most important secondary effect of earthquakes.
What are the causes and consequences of earthquake?
Earthquakes are caused by
sudden tectonic movements in the Earth’s crust
. … The stress increases when they stick, relative motion between the plates. This continues until the stress rises and breaks, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy as shock waves.
What factors influence the amount of ground shaking caused by earthquakes?
Many factors influence the strength of earthquake shaking at a site including
the earthquake’s magnitude, the site’s proximity to the fault, the local geology, and the soil type
.
