Which claim explains how elastic rebound takes place?

Which claim explains how elastic rebound takes place?

The energy released by an earthquake is the result of elastic rebound. Which claim explains how elastic rebound takes place? Pressure builds on rocks until they suddenly collapse.

Why is elastic rebound theory important?

Elastic rebound theory fits in well with the theory of plate tectonics and helps explains the cyclical nature of many earthquakes including why earthquakes repeatedly occur in the same regions.

How the processes of deformation and elastic rebound affect earthquakes?

Most natural earthquakes are caused by sudden slippage along a fault zone. The elastic rebound theory suggests that if slippage along a fault is hindered such that elastic strain energy builds up in the deforming rocks on either side of the fault, when the slippage does occur, the energy released causes an earthquake.

What is elastic rebound theory?

Similarly, the crust of the earth can gradually store elastic stress that is released suddenly during an earthquake. This gradual accumulation and release of stress and strain is now referred to as the “elastic rebound theory” of earthquakes.

Why the earthquake is dangerous?

The vibrations from an earthquake can lead to ground displacement and surface rupture. The surface rupture can cause other hazards, as well as damage to roads and buildings. In this example, the surface rupture has caused large cracks and the collapse of a paved road.

What scale of earthquake is dangerous?

What is the Richter Magnitude Scale?

Richter magnitude Description Earthquake effect
7.0-7.9 Major Can cause serious damage over larger areas.
8.0-8.9 Great Can cause serious damage in areas several hundred miles across.
9.0-9.9 Devastating in areas several thousand miles across.
10.0+ Epic Never recorded

How do you know when an earthquake is coming?

Though there is no way to pinpoint the exact arrival of an earthquake, scientists can examine sediment samples to get an idea of when major earthquakes occurred in the past. By measuring the amount of time between events, they can come up with a rough idea of when a major quake might hit.

What is the greatest magnitude earthquake ever recorded?

Science Center Objects

Mag Alternative Name
1. 9.5 Valdivia Earthquake
2. 9.2 1964 Great Alaska Earthquake, Prince William Sound Earthquake, Good Friday Earthquake
3. 9.1 Sumatra-Andaman Islands Earthquake, 2004 Sumatra Earthquake and Tsunami, Indian Ocean Earthquake
4. 9.1 Tohoku Earthquake

What was the longest lasting earthquake?

1960 Valdivia earthquake

What does a 9.5 magnitude earthquake feel like?

The shaking will feel violent and it will be difficult to stand up. The contents of your house will be a mess. A large earthquake far away will feel like a gentle bump followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while.

What would a 10.0 earthquake feel like?

Originally Answered: How would an earthquake of magnitude 10 on the Richter scale feel like? A magnitude 9.0 earthquake on Richter scale is equivalent to release of energy by 25,000 nuclear bombs. So a 10.0 magnitude earthquake will be analogous to dropping over 4,00,000 nuclear bombs at a time.

How bad is a 9.5 earthquake?

With a magnitude of 9.5, the earthquake was the most powerful such event of the 20th century. Other recent earthquakes have caused more damage and loss of life, however. The Indian Ocean tsunami of 2004 was caused by a magnitude 9.1 earthquake; it killed at least 225,000 people in a dozen countries.

Which claim explains how elastic rebound takes place?

Which claim explains how elastic rebound takes place?

The energy released by an earthquake is the result of elastic rebound. Which claim explains how elastic rebound takes place? Pressure builds on rocks until they suddenly collapse.

What does elastic rebound theory say?

The elastic rebound theory is an explanation for how energy is spread during earthquakes. As rocks on oppo- site sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their inter- nal strength is exceeded.

What are the steps in the elastic rebound theory?

The five stages of an earthquake are based on the elastic rebound theory, which geologist Henry Fielding Reid devised after the great 1906 San Francisco earthquake.

1. Elastic Buildup.
2. Dilatancy.
3. Influx of Water.
4. Earthquake.
5. Aftershocks.

Why is the elastic rebound theory important?

Elastic rebound theory fits in well with the theory of plate tectonics and helps explains the cyclical nature of many earthquakes including why earthquakes repeatedly occur in the same regions.

What does the elastic rebound theory explain quizlet?

Elastic rebound theory. IT DESCRIBES THE BUILD UP AND RELEASE OF STRESS DURING AN EARTHQUAKE. Rocks on either side of a fault are locked in place by friction. Rocks will slowly deform over time. When the stress exceeds the strength of the rock, the rocks will fault.

How does the elastic rebound theory explain the occurrence of earthquakes quizlet?

The theory that continuing stress along a fault results in a buildup of elastic energy in the rocks, which is abruptly released when an earthquake occurs.

Which tectonic boundary is responsible for the most powerful and destructive earthquakes recorded?

Reverse faults, particularly those along convergent plate boundaries are associated with the most powerful earthquakes, megathrust earthquakes, including almost all of those of magnitude 8 or more. Strike-slip faults, particularly continental transforms, can produce major earthquakes up to about magnitude 8.

Which best explains the earthquake cycle based on elastic rebound?

The percentage of all earthquakes that occur along plate boundaries is nearly: the energy released. Explain the earthquake cycle based on elastic rebound: Surface waves propagate more slowly.

What is fault creep?

In geology, aseismic creep or fault creep is measurable surface displacement along a fault in the absence of notable earthquakes. Aseismic creep may also occur as “after-slip” days to years after an earthquake.

How deep is a fault line?

Individual fault lines are usually narrower than their length or depth. Most earthquakes strike less than 50 miles (80 kilometers) below the Earth’s surface. The deepest earthquakes occur on reverse faults at about 375 miles (600 km) below the surface.

What prevents rocks from moving past each other in a fault?

What prevents rocks from moving past each other in a fault? friction. the stress becomes so great that the rocks of a fault suddenly grind past each other.

Is a magnitude 10 earthquake possible?

No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.

What magnitude earthquake would destroy the earth?

Magnitude Earthquake Effects Estimated Number Each Year
6.1 to 6.9 May cause a lot of damage in very populated areas. 100
7.0 to 7.9 Major earthquake. Serious damage. 20
8.0 or greater Great earthquake. Can totally destroy communities near the epicenter. One every 5 to 10 years
