Ziggurats Lab Report

The main idea of the video Bill Nye Earthquakes is that it talks about how earthquakes occur and what makes an earthquake happen. First of all, every year there are thousands of earthquakes all around the world. Earthquakes happen when the Earth’s surface shifts a little. Some earthquakes can go left, right, or up and down. In addition, the Earth’s surface is floating on molten liquid rock, a semi-solid and a semi-liquid. The Earth’s surface is broken down into plates or plate tectonics. Scientists use seismometers to measure earthquakes and when you record that it’s called seismograph. Accordingly, when plates move apart or come together we get volcanoes and when plates move together we can get mountains. When an earthquake happens scientists

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada, an area of approximately 200,000 square miles. The ground motion caused by the earthquake source is recorded by instruments called seismographs. The zigzag trace made by a seismograph, called a "seismogram," reflects the changing amplitude and frequency content of the ground shaking beneath the instrument (usgs.gov). Using seismograms, scientists can determine the time, the epicenter, the depth, and the type of faulting of an earthquake as well as estimate how much energy was released by it.

Earthquakes are caused when two blocks of earth suddenly slip past one another. The surface where the two blocks slip is called the fault. The earthquake starts below the earth’s surface at the hypocenter, and the location above the hypocenter is called the epicenter. Earthquakes can have foreshocks which is a smaller earthquake that happens before the larger quake. Earthquake can also

The energy coming from this rupture is called seismic waves. These waves fan out in every direction from the earthquakes epicenter and results in intense shaking. Once this shaking reaches the earth’s surface, everything from the ground up will also proceed to shake (Wald 2012). In order to measure the size of an earthquake, scientists use seismographs. Seismographs consist of a base, a spring, pen, rotating drum, and a heavy weight. The base is placed in the ground while the weight hangs above. When an earthquake occurs the spring absorbs the shaking and the weight and pen, which remain motionless, record the difference between the shaking and motionless part of the seismograph. Seismograph recordings consist of short and long wavy lines, with long lines indicating a larger earthquake (Wald 2012). These recordings are then

This causes the ground to shake either not that hard or vigorously. What some folks don’t know is that there happens to be many earthquakes every day just we do not happen to feel them as much. Other earthquakes are huge and have a big impact.

these foreshocks are very small pre earthquakes some not being big enough to even measure on a seismograph. These foreshocks are being studied by scientist to determine if there is a way to use these shocks to our advantage. Scientists soon hope one day to be able to measure these foreshocks and pin point exactly where the main earthquake will happen.

The image below shows orange dotted lines representing fault lines which led to the earthquake.

By definition an earthquake is the tremor of the surface of the Earth, sometimes severe and devastating, which results from shock waves generated by the movement of rock masses deep within the Earth, particularly near boundaries of tectonic plates. The tectonic plates involved in the 2010 Chile earthquake were the Nazca and South American plate, and like all tectonic plates, they often move due to convection currents within the Earth’s mantle. This movement can cause tectonic plates to collide, separate or slide past one another. For thousands of years, the oceanic Nazca plate has been colliding and slowly subducting underneath the continental side of the South American plate. Earthquakes can be caused by a variety of reasons, but the 2010 Chilean earthquake was caused by these two tectonic plates having an ocean-continental collision at a convergent boundary.

Earthquakes are sudden trembling or shaking vibrations. Earthquakes are large spinning spiral winds, that comes together by rocks underground breaks along the fault. There are two types of earthquakes, there is the body waves and the surface waves. Body waves travel at 7/8 km. The body wave is the fastest of the two waves. The surface waves act as a gravity waves that are between two fluids with different density. Unlike hurricanes,

Earthquakes are caused when rock at an underground fault breaks. This release of energy causes seismic waves (Endsley). There are P waves, S waves, and surface waves (Hogan). This is the main cause of earthquakes, though there has been a few, rare occurrences

The earthquake had Seismic Waves because the ground precisely outbreak open. It was also a Primary Wave because the earthquake was traveling 100 miles per hour. (Casey Farrell, UWEC), (Extreme Science) The damage that was destructed by the Chile quake was major. The quake caused around 500 Million Dollars worth of destruction.

     Earthquakes, called temblors by scientists, occur almost continuously. Fortunately, most of them can be detected only by sensitive instruments called seismographs. Others are felt as small tremors. Some of the rest, however, cause major catastrophes. They

Earthquakes are caused by the movements of the earth. Large blocks of stone called tectonic plates are constantly moving creating friction and stress with each other. These earthquakes then cause massive damage above the surface. There are three different types of earthquakes.

More than a million earthquakes rattle the world each year. But, most are so small that they can only be detected by sensitive instruments called seismogram.
