What are the 4 parts of an earthquake?

It’s these waves that you feel during an earthquake.

• Fault: A fracture in the rocks that make up the Earth’s crust.
• Epicenter: The point at the surface of the Earth above the focus.
• Plates: Massive rocks that make up the outer layer of the Earth’s surface and whose movement along faults triggers earthquakes.

What are the three stages of an earthquake event?

There are many things you can do to help yourself in the event of an earthquake. Generally, an earthquake is divided into three stages: before, during, and after. Know what to do in each stage.

What are the 5 steps after an earthquake?

The following earthquake preparation tips take a few hours to create a plan and organize supplies that will keep you safer.

• Step 1: Secure Your Space. Secure your space by identifying hazards and securing moveable items.
• Step 2: Plan to be Safe. …
• Step 3: Organize Disaster Supplies. …

What are the different stages of earthquake?

The seismic cycle can be divided into three periods, consisting of inter-seismic slip, co-seismic slip, and post-seismic slip.

What are the 4 types of earthquakes?

There are four different types of earthquakes: tectonic, volcanic, collapse and explosion. A tectonic earthquake is one that occurs when the earth’s crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.

What are the 4 steps in the earthquake process?

Stages of an Earthquake

• Elastic Buildup. The elastic rebound theory is based on the concept that the earthquakes result from forces nowhere near the actual earthquake. …
• Dilatancy. Stage two occurs when the rocks in the Earth are packed together as closely as possible. …
• Influx of Water. …
• Earthquake. …
• Aftershocks.

What are the part of the earthquake?

The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.

What 4 factors affect intensity of an earthquake?

When an earthquake strikes, the intensity of earthquake shaking determines the severity of damage. In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristicsparticularly height

What are the stages of the earthquake cycle?

The earthquake cycle includes the phase of accumulation of elastic strain energy with tectonic loading (phase II), and the phase of rupture nucleation at the critical stage where an adequate amount of the elastic strain energy has been stored (phase III).

What are the events of an earthquake?

An earthquake is the ground shaking caused by a sudden slip on a fault. Stresses in the earth’s outer layer push the sides of the fault together. Stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the earth’s crust and cause the shaking that we feel during an earthquake.

What do we do after an earthquake?

What do I do AFTER an earthquake?

• If a person is bleeding, put direct pressure on the wound, use clean gauze or cloth if available.
• If a person is not breathing administer CPR.
• DO NOT attempt to move seriously injured persons unless they are in further danger of injury.
• COVER injured persons with blankets to keep warm.

What are the 3 types of earthquake?

Three Kinds of Earthquakes

• Shallow fault earthquakes. A fault is a break in the rock beneath our feet. …
• Subduction zone earthquakes. The largest earthquakes ever recorded are subduction zone earthquakes. …
• Deep earthquakes. Deep earthquakes occur in the subducting ocean slab, deep beneath the continental crust.

What are the 4 earthquake faults?

There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.

What are the 4 main causes of earthquakes?

Causes of Earthquakes in General

• Induced Earthquakes. Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
• Volcanic Earthquakes. Volcanic quakes are associated with active volcanism. …
• Collapse Earthquakes.

What are the 4 parts to an earthquake?

The four types of earthquakes are tectonic, volcanic, collapse, and explosion. Tectonic earthquakes are the result of tectonic plate movement. Volcanic earthquakes are the result of a slip of a fault near a volcano.
