Earthquakes: collateral effects Ground shaking. Shaking of the ground caused by the passage of seismic waves, especially surface waves near the epicentre of the earthquake are responsible for the most damage during an earthquake. The intensity of ground shaking depends on: 1  conditions of the local geology influence evenuts: solid bedrock is far less subject to intense shaking than loose sediment; 2  duration and intensity of the earthquake are subject generally to the size of the earthquake;

What are earthquake waves? Introduction. Earthquake waves are seismic waves that are created when energy builds up in rocks and they fracture. Scientists estimate there are several million earthquakes each year. Every earthquake produces P waves and S waves but only larger earthquakes produce Love waves and Rayleigh waves.

- Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs. Types of Seismic Waves. There are several different kinds of seismic waves, and they all move in different ways.The two main types of waves are body waves and surface waves.arthquakes radiate seismic energy as both body and surface waves. Body Waves. Traveling through the interior of the earth, body waves arrive before the surface waves emitted by an earthquake. These waves are of a higher frequency than surface waves.

Why does the Earthquake at Chile happen (1960) ? When the failure at the fault plane results in a violent displacement of the Earth's crust, the elastic strain energy is released and seismic waves are radiated, thus causing an earthquake. This process of strain, stress, and failure is referred to as the Elastic-rebound theory.

Locating and measuring earthquakes As the wave passes by a seismic station, that piece of ground vibrates and this vibration is recorded. Earthquakes produce two main types of waves-the P-wave (a compressional wave), and the S-wave (a shear wave).The S-wave is slower but larger than the P-wave and does most of the damage.s the wave passes by a seismic station, that piece of ground vibrates and this vibration is recorded.

- It depends on resonance!! During an earthquake buildings oscillate, but not all buildings respond to an earthquake equally. If the frequency of oscillation of the ground is close to the natural frequency of the building, resonance (high amplitude continued oscillation) may cause severe damage. Small Buildings: Small building are more affected, or shaken, by high-frequency waves (short and frequent). For example, a small boat sailing in the ocean will not be greatly affected by a low-frequency swell where the waves are far apart.

- The three types of seismic waves are primary waves, secondary waves and surface waves. Seismic waves can cause earthquakes and have destructive capability. Primary and secondary waves are known as body waves, and these waves penetrate the interior of the Earth, whereas surface waves do not penetrate the Earth. Keep Learning.

Scientists on the side of the Earth opposite the epicenter of an earthquake detect mainly what?? If I understand your question correctly you want to know what siesmologists detect on the opposite side of earth during an earthquake. First off one needs to understand that there are three kinds of shockwaves a quake releases S-waves(Secondary) and P-waves(Primary) and surface waves. S-waves travel about 2mp/s.-waves travel about 4mp/s. The speed of the surface waves is dependent on the size of the quake. But it is only the P-Waves that are able to pass through liquid. Like the core that is liquid that is how scientist were able to tell that the core of the earth was a molten ball of liquid magma.

1960 Valdivia Earthquake or Great Chilean Earthquake The temblor caused localised tsunamis that severely battered the Chilean coast, with waves up to 25 metres. Image: Aerial view of coastal area on Isla Chiloe, Chile, showing tsunami damage and wave extent. Two hundred deaths were reported here from the tsunami generated just off Chile's coast by the earthquake.

How Earthquakes Work Seismic Waves. When you toss a pebble into a pond, it creates radiating waves in the water. An earthquake does the same thing with energy. When the plates fracture or slip, energy is released as seismic waves [source: USGS ]. There are several types of seismic waves. Body waves move through the inside of the Earth. There are two types of body waves: Primary waves (or P waves) are the fastest moving waves, traveling at 1 to 5 miles per second (1.6 to 8 kilometers per second). They can pass through solids, liquids and gases easily.

How Do Earthquakes Cause Damage ? A: Earthquakes cause direct damage when the seismic disturbance weakens and collapses buildings and other infrastructures not built to withstand the tremors. This often causes great loss of life. Other damage caused by earthquakes results from landslides, mudslides, avalanches, fires, soil liquefaction and tsunamis. Continue Reading

What are some unique characteristics of the most destructive earthquake waves? Body waves. Body waves are of two types: compressional or primary (P) waves and shear or secondary (S) waves. P- and S- waves are called body waves because they can travel through the interior of a body such as the Earth's inner layers, from the focus of an earthquake to distant points on the surface. The Earth’s molten core can only be travelled through by compressional waves. P-waves travel fastest, at speeds between 4–8 km/sec (14,000–28,000 km/h) in the Earth's crust. S-waves travel more slowly, usually at 2.5–4 km/sec (9000–14,000 km/h).

Tsunami Questions A tsunami is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion. Tsunamis are NOT tidal waves. Tidal waves are caused by the forces of the moon, sun, and planets upon the tides, as well as the wind as it moves over the water. With typical waves, water flows in circles, but with a tsunami, water flows straight. This is why tsunamis cause so much damage!

Earthquake At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.or instance, an earthquake of magnitude 6.0 releases approximately 30 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 900 times (30 × 30) more energy than a 5.0 magnitude of earthquake.

Earthquake Earthquakes are caused mostly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake’s point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.arthquakes often occur in volcanic regions and are caused there, both by tectonic faults and the movement of magma in volcanoes. Such earthquakes can serve as an early warning of volcanic eruptions, as during the Mount St. Helens eruption of 1980.

- By far, the most destructive tsunamis are generated from large, shallow earthquakes with an epicenter or fault line near or on the ocean floor.These usually occur in regions of the earth characterized by tectonic subduction along tectonic plate boundaries.ost tsunamis are generated by shallow, great earthquakes at subductions zones. More than 80% of the world's tsunamis occur in the Pacific along its Ring of Fire subduction zones.

- Earthquakes occur when energy stored in elastically strained rocks is suddenly released. This release of energy causes intense ground shaking in the area near the source of the earthquake and sends waves of elastic energy, called seismic waves, throughout the Earth.

- When an earthquake occurs, it releases energy in the form of seismic waves that radiate from the earthquake source in all directions. The different types of energy waves shake the ground in different ways and also travel through the earth at different velocities. The fastest wave, and therefore the first to arrive at a given location, is called the P wave. The P wave, or compressional wave, alternately compresses and expands material in the same direction it is traveling. The S wave is slower than the P wave and arrives next, shaking the ground up and down and back and forth perpendicular to the direction it is traveling. Surface waves follow the P and S waves.
