What happens to the earth after an earthquake?

Earthquakes occur unexpectedly and with little or no notice. However, aftershocks after a strong earthquake might occasionally signal the risk of another earthquake. An earthquake may be preceded by less powerful tremors or foreshocks on rare instances. Sometimes an eruption of a volcano will precede an earthquake.

After an earthquake, damage can be caused by the collapse of buildings and other civil engineering structures. Other dangers include landslides and floods caused by broken water pipes or eroded soil banks. The destruction of homes can lead to loss of life if people are not warned about risks to their safety. In addition to human casualties, animals can be killed by collapsing buildings or buried under rubble. The land itself can be damaged by erosion caused by flooding or mudflows.

Civilization as we know it would come to an end in a major way if an earthquake were to happen today. Most buildings in most cities are made of concrete which would crumble under the force of a major quake. Even some brick buildings would suffer damage due to poor construction. A lot of people would likely be killed by falling objects or debris from collapsing buildings.

After a major earthquake, much of the surface area affected will be covered in rubble. This makes walking around with rescue tools difficult if not impossible. It is important to realize that even years after an earthquake many areas are still at risk for further earthquakes.

What other geologic events can occur after an earthquake?

An earthquake, depending on its magnitude and location, can induce physical phenomena such as ground shaking, surface fault rupture, ground failure, and, in some coastal locations, tsunamis. Aftershocks are minor earthquakes that may occur several hours, months, or even years after the original shock. They usually do not cause any damage themselves, but they can tell us something about the depth and extent of the original quake.

There are three main types of seismic waves: P-waves, S-waves, and L-waves. P-waves travel through solid rock and explain why seismic surveys only find out about the presence or absence of rocks under water or soil. If a large enough force shakes a region of the earth's surface, then P-waves will propagate through it. S-waves go only along with surfaces where there is solid material on both sides of the wave (such as the bottom of a trench). L-waves only travel along paths where there is solid material on one side of the wave (such as the wall of a tunnel). Seismologists use these terms to describe the most common patterns seen in seismic data.

All earthquakes release energy as heat. This energy can be detected by measuring changes in temperature. In particular, near the surface of the Earth, ice tends to melt in warmer weather and re-freeze in cooler weather.

What does the aftermath of an earthquake look like?

A huge earthquake nearby would feel like a sudden large shock followed by additional intense shaking that might continue a few seconds or up to a couple of minutes if it's a rare great occurrence. A little earthquake will feel like a short sharp jolt followed by a few bigger sharp tremors that pass swiftly. The intensity of the shock depends on the depth of the fault at which it occurs - deeper faults produce more intense shocks.

Aftershocks are waves that come from the original quake. They can be felt several hours later when the pressure of the rock above the fault releases as it moves back down toward the source rock bed, only this time without the help of gravity. At first, they are too small to be felt but with time they get stronger and stronger until you can finally see them on the seismogram. There can be many hundreds of aftershocks in rapid succession after a major quake.

The seismic wave travels through Earth's solid material forming reflections and refractions that are detected by sensors placed on land or under water. Seismometers work by detecting changes in force applied to their containers caused by movement of air inside them. Accelerometers used in handheld devices measure displacement along three axes resulting in information about the origin and magnitude of the earthquake.

Seismographs use variations in light intensity to detect vibrations. Modern seismographs use electronic components to record vibrations as pulses or bursts of energy.

What usually happens after an earthquake?

There will be aftershocks. Aftershocks may occur following an earthquake. Aftershocks are minor earthquakes that occur as a result of a bigger earthquake. These can occur minutes, hours, days, weeks, or even months following an earthquake. Drop, cover, and hold on if you feel an aftershock. If you're in open water, find safe ground immediately.

When someone hears the word "aftershock," they probably think about the destructive power of earthquakes. However, this danger has been greatly exaggerated. The risk of being killed by a tsunami or other disaster source is much greater than the risk of being killed by an aftershock. In fact, scientists estimate that an individual is more likely to be killed by lightning than by an aftershock.

However, it's important to remember that damage can be done even by mild aftershocks. Stronger aftershocks can cause new damage far away from where the original quake occurred. Remain alert for information about any changes or problems with the safety of your home environment. Check out our article on environmental issues related to earthquakes for more information.

After an earthquake, look around your house and yard for signs of damage. Is anything broken? If so, call 9-1-1 right away to report the incident.
