Major Earthquakes are Inevitable in Indiana’s Future
An earthquake felt throughout the Midwest on June 18 was a shaky reminder that earthquakes can occur anywhere.
The earthquake, whose epicenter was located north of Evansville, was felt through most of Indiana and surrounding states, as reported by the Indianapolis Star. The quake was not the largest in Midwestern history, only registering a 5.0 on the Richter scale, nor did it do much damage.
Earthquakes occur almost everyday all over the world. Most of the time earthquakes are not strong enough to be felt by people, but the shaking caused by an earthquake can be recorded by a seismometer. These machines are located all over the world to ensure detection of earthquakes of all strengths. Only occasionally will a larger magnitude earthquake strike and cause damage to the region. There are many faults around the world and depending on where these faults are plays a major factor in determining where an earthquake will occur.
The hypocenter, where the earthquake starts, sends out shock waves that may be powerful enough to alter the surface of the earth by creating cliffs and opening up large cracks in the ground. Earthquakes can also cause lots of damage. They can collapse buildings and other manmade structures, break power, water and gas lines, cause landslides, snow avalanches tsunamis and cause volcanoes to
Earthquakes happen all round the world daily and they are extremely dangerous. An earthquake is caused by the movement of plates called fault. Plates are segments of the outermost rigid shell of the Earth, composed of the crust and attached upper mantle, which float on the plastic like asthenosphere. Faults are in deep underground, they are always moving slowly that we can’t even feel it. Seismologists are studying how to predict an earthquake to be safer in the earthquake by learning and studying the seismic waves. There are many earthquakes that happen around the world, occurring for many different reasons, causing damage, and helping seismologists to learn and study seismic waves.
Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.
“Earthquakes don’t have the ability to kill or cause harm, however buildings do.” This is a famous quote that tries to emphasize on the need for earthquake precautions and measures especially in buildings. Earthquakes, just like other natural calamities, cannot be prevented, though it is possible to minimize their impacts and effects. Like other natural calamities, earthquakes have the ability to cause harm and damage to both life and property. Two basic types of seismic waves are responsible for causing earthquakes (Chang, & Soong, 1992). These two waves are distinguished by the speeds at which each of them travels through the earth. Primary or push waves travel faster and they are longitudinal in nature. These waves have the ability to pass through liquids too. The slower waves are referred to as secondary or shake waves. These waves travel like light waves, though they cannot travel in liquids.
Earthquakes are sudden, violent shakings in the ground that is caused by the movement of the Earth’s crust or volcanoes. More than 10,000 earthquakes take place every year, most of them not recognized by humans. Earthquakes do not occur at random locations, however, as some people believe. A pattern can be seen where most earthquakes occur at or near the plate boundaries. In fact, these earthquakes are what help scientists discover where these plate boundaries are. Plate boundaries are the cracks between the set of tectonic plates that make up the Earth’s crust. The moving of these tectonic plates is what causes these earthquakes. There are three types of plate boundaries: divergent boundaries, convergent boundaries, and transform boundaries.
On the 18th of April in 1906, the lives of many San Francisco residents changed in a split second. Most of the city was either sound asleep or getting ready for another normal day (or so they thought), when the disastrous natural disaster struck. At around 5:12 a.m., the Golden City was jolted awake by a monstrous earthquake that would soon go down in the record books. With a Richter magnitude rating of 7.9, this earthquake was not only felt in the San Francisco Bay area, but also all the way from southern Oregon to south of Los Angeles and inland as far as central Nevada.
Earthquakes evidence themselves by shaking, trembling, and sometimes movement of the ground. They are caused by a slipper in the inner earthly faults. They can swing in capacity and in size, from the ones that are so weak that people don’t even feel, to those that can toss people around and can also destroy an entire city with its violent movement. Earthquakes by themselves unfrequently kill people. It is usually the secondary events, like buildings collapsing, tsunamis, fires, and volcanoes. Many of this type of things can be avoided by a better construction, early warning, and safety
This is one of the most commonly asked questions around the world. Earthquakes are very common because the Earth’s tectonic plates are constantly moving, because they are constantly moving earthquakes are happening quite often across the globe. Statistics show that over 1 million occur each year worldwide (see source 9), but earthquakes don’t have to be felt for them to have occurred. Statistics prove that 1 100 000 earthquakes happen per year worldwide that can’t be felt by humans. Statistics show that about 11 670 earthquakes occur that can be felt in the area of occurrence and sometimes even further
