Where does maximum damage occur due to an earthquake?

Greatest damage is caused closest to the epicentre because vibrations travel outwards from the epicentre and that the strength of the earthquake decreases away from the centre.

What happens at the Epicentre of an earthquake?

The point on the Earth’s surface above the focus is called the epicentre . Earthquake energy is released in seismic waves. These waves spread out from the focus. The most severe damage caused by an earthquake will happen close to the epicentre.

What are the damages caused by earthquake?

Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis. The extent of destruction and harm caused by an earthquake depends on: magnitude. intensity and duration.

Why is there less damage away from the Epicentre?

Answer: There is less damage away from the epicentre because it is the point where an earthquake originates and we go farther there is less damage from the earthquake.

Are earthquakes the strongest at epicenter?

The location inside the Earth where an earthquake begins is called the focus (or hypocenter) of the earthquake. 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 causes damage and destruction in an earthquake?

The damage caused by earthquakes is from ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Earthquake damage from fires is the most important secondary effect.

What causes the most structural damage during earthquakes?

Ground shaking is a term used to describe the vibration of the ground during an earthquake. S waves arrive next and cause a structure to vibrate from side to side. They are the most damaging waves, because buildings are more easily damaged from horizontal motion than from vertical motion.

Where is the epicenter of earthquake?

The epicenter is the point on the earth’s surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.

Which instrument determines the amount of damage caused by earthquake?

The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Why earthquake is stronger near the epicenter?

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. Sometimes the ground surface breaks along the fault. Sometimes the movement is deep underground and the surface does not break.

When earthquakes occurs where would Shaking be greater near the epicenter or away from the epicenter Why?

The shaking experienced close to an earthquake’s epicenter is more severe because there is greater energy available to move the ground at this…

What is the damage of an earthquake?

The damage caused by earthquakes is from ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Earthquake damage from fires is the most important secondary effect. Northridge, at a 6.7 magnitude earthquake, killed 58 people, injured more than 9,000 and caused more than $49 billion in economic loss.

Where is the epicenter of an earthquake?

, works at Medical Devices. For the most part, an earthquake will be most intense at the epicenter, but that is not always the case. In Seismology, the epicenter is the point on the Earth’s surface directly above the point where the fault begins to rupture, and in most cases, it is the area of greatest damage.

What is the difference between an epicenter and a fault rupture?

The epicenter is the location at the surface closest to the starting point of an earthquake. For earthquakes of moderate size, the fault rupture is small relative to the depth, so the epicenter is also closest to the main fault rupture.

How does the location of an earthquake affect the damage?

cular location will determine the earthquake damage. The extent of ground shaking will depend upon the scale of an earthquake, distance from the epicenter, and nature of the material. When the earthquakes are great, the amplitude is large, duration is more, and the area is vast.

Why do shock waves travel from the epicenter to the surface?

Because the epicenter is more or less just above the point where the fault line ruptured. That is where the shock waves originate. Then, they travel on the surface of the earth like ripples on a pond. So as they travel and move further and further away from the epicenter, the shock gets absorbed on the way and the strength of the wave lessens.
