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.
