Earthquake VS Tsunami



An abrupt and violent shaking of the ground, (sometimes triggering fantastic damage,) as a result of motions within the earth’s crust.
An earthquake is the result of an unexpected release of energy in the Earth’s crust that creates seismic waves.
An earthquake is a natural phenomenon like rain. Earthquakes are caused by the continuous movement of Earth’s surface area. This motion produces accumulation and launches energy stored in rocks at and near the Earth’s surface area.


Tsunamis are big powerful water waves caused by abrupt displacement of large volume of water in the sea/ ocean. Tsunami is the Japanese word for harbor wave.
Tsunami is a series of water waves triggered by the displacement of a huge volume of a body of water.

Way Earthquake happens:

Earthquakes are generally triggered when rock underground all of a sudden breaks along a fault. This abrupt release of energy causes the seismic waves that make the ground shake. When two blocks of rock or more plates are rubbing versus each other, they stick a little. They do not simply slide smoothly; the rocks capture on each other. The rocks are still pushing versus each other, but not moving. After a while, the rocks break due to the fact that of all the pressure that’s built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The location right above the focus (on top of the ground) is called the center of the earthquake.

Just we can state that when the seismic waves Launched then there is a chance of occurring earthquake.

A seismometer is an instrument that senses the earth’s motion; a seismograph integrates a seismometer with recording devices to acquire a permanent record of the motion.

Method Tsunami happens:

A tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms. A tsunami takes a trip at a speed that belongs to the water depth – hence, as the water depth decreases, the tsunami slows. The tsunami’s energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Subsequently, as the tsunami’s speed reduces as it travels into shallower water, its height grows.

Ocean observing instruments, that have the ability to spot tsunamis.

Tsunamis can be caused by a few various ways:

1) The down drop or upturns of the Earth’s crust which results in an earthquake.

2) Massive under sea landslide.

3) Submarine volcanic eruption of a certain degree; or possibly,

4) Big meteor impact at sea. The huge majority of tsunamis result from earthquakes.

Where Earthquakes Happens:

Areas of the crust are fractures, referred to as faults, along which two crustal blocks have actually slipped or moved versus each other. One block may go up while the other moves down, or one might move horizontally in one direction and the other in the opposite instructions. Earthquakes happen.

Earthquakes normally happen where 2 of the earth’s tectonic plates date. These border areas, therefore, are particularly prone to earthquakes (and also to volcanic eruptions). The edges of the huge Pacific plate, which lies below the Pacific Ocean, form an especially extreme ring of tectonic activity, understood as the “ring of fire.” repeatedly at faults, which are zones of weakness in the earth’s crust.

Where Tsunami Occurs:

Tsunami can be produced when the sea floor quickly deforms and vertically displaces the overlying water. Such large vertical motions of the Earth’s crust can take place at plate boundaries. Seductions earthquakes are especially effective in creating tsunami.

Where Tsunamis are occurred not even tectonic plate borders are equal in producing events. 4 out of every 5 tsunamis that take place take place in the region called the Ring of Fire. This area that rings the Pacific Ocean basis has a few of the most active plate borders on the planet. If a significant earthquake occurs here is it will certainly be strong enough to trigger a tsunamis.


Absolutely nothing can be done to avoid Earthquakes and Tsunamis as they take place naturally. But their impacts can be decreased.

Earthquake education and preparedness plans can help significantly minimize death and injury triggered by earthquakes.
Earthquake preparedness consists of keeping an earthquake kit and making sure that your house is structurally steady.

Area Hit by Huge Pakistan Quake as Shown by NASA Spacecraft

On September 24 at 11:29 GMT, a magnitude 7.7 earthquake struck in south-central Pakistan at a reasonably shallow depth of 20 kilometers. The earthquake occurred as the outcome of oblique strike-slip motion, constant with rupture within the Eurasian tectonic plate. Tremblings were felt as far as New Delhi as well as Karachi in Pakistan. Even though the instant area to the epicenter is sparsely inhabited, most of houses are of mud brick building and damage is anticipated to be substantial. The perspective view, looking to the east, reveals the place of the epicenter in Pakistan’s Makran fold belt. The image is focused near 27 degrees north latitude, 65.5 degrees east longitude, and was acquired December 13, 2012.

With its 14 spectral bands from the noticeable to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and keep an eye on the changing surface of our world. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan’s Ministry of Economy, Trade and Market. A joint U.S./ Japan science team is responsible for recognition and calibration of the instrument and information products.

The broad spectral protection and high spectral resolution of ASTER provides scientists in various disciplines with important details for surface mapping and monitoring of vibrant conditions and temporal change. Example applications are: keeping track of glacial advances and retreats; keeping an eye on potentially active volcanoes; determining crop tension; determining cloud morphology and physical buildings; wetlands evaluation; thermal contamination monitoring; reef degradation; surface area temperature level mapping of soils and geology; and measuring surface area heat balance.

The United States science team lies at NASA’s Jet Propulsion Lab, Pasadena, Calif. The Terra mission becomes part of NASA’s Science Objective Directorate, Washington, D.C
