Name and Explain Four Different Types of Earthquakes

Body waves refer to the combination of P-waves and S-waves. There are four main types of seismic waves each characterized by its specific particle motion.

Classification Of Earthquakes Types Effects Detection And More

The abrupt and violent nature of earthquakes mean many injuries are due to falling objects.

. The point in the earths crust where the movement originates is called the focus. Earthquakes are usually classified on the following bases. When the Lithospheric plates shift the earths surface vibrates which gives rise to earthquakes.

Tectonic volcanic and explosion. These faults usually occur in areas where the plate is splitting apart very slowly. In coastal areas a powerful offshore quake could trigger a tsunami a.

When source zone is used to categorize earthquakes the. A Cause of origin. Types of Earthquake Waves.

When the rock breaks under the feet it is called a fault. Or in the same direction but at different speeds. Tectonic volcanic collapse and explosion.

For example during the 2001 Nisqually earthquake that shook the Puget Sound region buildings crumbled bridge supports cracked and more than 400 people were injured. One piece slides downwards away from the other due to crustal stretching. On the basis of the causes of earthquake they are classified as- i Tectonic and ii Non-tectonic earthquakes.

A Cause of Origin. Explosive earthquakes are often man-made and the two terms may be used interchangeably. There are four different types of earthquakes.

Earthquakes pose several hazards to our natural and built environment. This is important because it ca cause damage to whole regions. These occur when rocks in the earths crust break due to geological forces created by movement of tectonic plates.

Tectonic earthquakes generate some of the largest seismic waves. The following is an overview of four types of natural disasters and the specific injuries that a hospital would usually encounter. Plates rip apart at a divergent plate boundary causing volcanic activity and shallow earthquakes.

Different types of plate boundaries. Redrawn from University of Otago Richard Sibson 1. Induced seismicity typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earths crust.

The most common are tectonic earthquakes. Where the crust is being pulled apart normal faulting occurs in which the overlying hanging-wall block moves down with respect to the lower foot wall block. Most earthquakes do not cause damage as they are small or occur in unpopulated areas.

The cause or source zone is sometimes used as a way to categorize earthquakes. In the areas of intense mining. Huge shift in land level happens.

The most common ones are the tectonic earthquakes. There are three types of tectonic plate boundaries. There are four different types of earthquake and each with special characteristics.

Tectonic volcanic collapse and explosion. Different parts of Cascadia will experience different hazards. The type of earthquake depends on the region where it occurs and the geological make-up of that region.

Draw sketches to support your explanation. When an earthquake happens it sends forth energy waves known as seismic waves. The non-tectonic earthquakes are mainly of three types due to surface causes.

This fault is defined by. Different Types of Earthquake. So earthquakes occur within and through these faults.

Illustrate and explain different types of seismic waves focus epicentre and focal depth of an earthquake caused by block movement. A special class of tectonic earthquake is sometimes recognised as volcanic earthquake. B Depth of focus.

On the Basis of the depth of their Foci there are three earthquake types they are Deep-focus earthquakes Intermediate focus earthquakes and Shallow-focus earthquakes. C Intensity and magnitude of earthquake. Intraplate earthquake an earthquake that occurs within the interior of a tectonic plate.

The Earths lithosphere which includes the crust and upper mantle is made up of a series of pieces or tectonic plates that move slowly over time. When earthquakes are categorized by cause types include tectonic earthquakes volcanic earthquakes and explosive earthquakes. A tectonic earthquake is one that occurs when the earths crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.

These are generated due to sliding of rocks along a fault plate. These earthquakes happen in the Subduction area of the earth along the Subduction zone. A tectonic earthquake is one that occurs when the earths crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.

There are 5 types of earthquake. Unfortunately sometimes that power manifests itself as a natural disaster. Compressional Waves p waves are identical to sound waves the particle motion is parallel to the propagation direction.

These vibrations can progress all-around the earth. P-wave animation by LW. -rocks on opposite sides of fault are bent and deformed instead of slipping as they bend they accumulate energy.

A divergent boundary occurs when two tectonic plates move away from each other. There are four different types of earthquakes. Explain how earthquakes occur according to the elastic rebound theory.

Where the crust is being compressed reverse faulting occurs in. P S L Waves Seismography Explained. However these are confined to.

As the plates try to move friction occurs and plates become stuck. There are four types of faults- 1. These faults are close to the surface of the earth a small quake can cause a lot of damage.

Waves produced by Earthquakes. The landscapes of our national parks as well as geologic hazards such as earthquakes and volcanic eruptions are due to the movement of the large plates of Earths outer shell. This type of earthquakes occur at.

Types of movement of crustal blocks that can occur along faults during an earthquake. Its similar to the ripples that occur when a stone is thrown into the water. Normal fault- Normal faults are when two pieces of rock are moving in different directions divergent boundary.

There are many different types of earthquakes. P-waves S-waves and surface waves are the three primary forms of seismic waves. Enumerate the causative factors of an earthquake.

Tectonic Earthquake - They account for most earthquakes worldwide and usually occur at the boundaries of tectonic plates. Along these boundaries earthquakes are common and magma molten rock rises from the Earths mantle to the surface solidifying to create. Interplate earthquake an earthquake that occurs at the boundary between two tectonic plates.
