When stress is applied to all sides of the crust Brainly?
Answer: When stress is applied to all sides of the crust, confining stress occurs. When this happens, the crust compacts, which makes it look smaller. If the stress is too much for the crust to handle, the crust can fracture from the inside.
What point along the fault where movement first occurs Brainly?
The point along the fault where first break or movements first occur is called the focus or hypocenter. The focus is directly below the epicenter (center of a surface).
When an earthquake occurs where would Shaking be greater?
Answer: The point at the Earth’s surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake.
What is the relationship between faults and earthquakes?
Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
What are four main dangers associated with earthquakes?
Earthquake Hazards
- 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.
- Tsunami.
- Landslides and Rockfalls.
- Subsidence and Lateral Spreading.
- Liquefaction.
What are the 6 potential earthquake hazards?
earthquake hazard This includes surface faulting, ground shaking, landslide, liquefaction, tectonic deformation, tsunamis, and seiches.
What are the primary and secondary earthquake hazards?
Primary hazards are caused by the direct interaction of seismic wave energy with the ground. Secondary hazards are caused as a consequence of that ground shaking, such as ground settlement, lateral ground displacement, liquefaction, landslides and rock falls, tsunamis, floods, fires and falling debris.
What is 1 on the Richter scale?
The Richter scale is a scale of numbers used to tell the power (or magnitude) of earthquakes. Charles Richter developed the Richter Scale in 1935….More examples.
| Approximate Richter Magnitude number | Seismic energy equivalent: Amount of TNT | Example event |
|---|---|---|
| 6.0 | 1 megaton | Double Spring Flat earthquake (NV, USA), 1994 |
