Disciplinary Core Ideas PS4-1 Summary

In Valdivia, Chile 1960 an earthquake changed the lives of many. An earthquake is the violent shaking of the ground that will destroy homes, buildings, landforms, historical monuments, and lives. Earthquakes begin with the breakage of rock along a fault line. When two tectonic plates rub against each other they create an earthquake. Earthquakes will ride along a fault line which will determine how long the quake will go on. The larger and longer the fault like the bigger the earthquake. Earthquakes send out waves, primary waves or, p waves and secondary waves or, s waves travel along the interior of the earth. These two waves are called body waves. While detecting the waves, the primary waves appear first then the secondary waves. Primary waves travel through solids, liquids, and gasses, which means they are about to travel through the liquid center. Secondary waves are only able to travel through solids which are why scientists have found that there is a loss of these waves once they reach the center.

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.

13) If you ran the same experiment without passing light through a prism, what would you predict?

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,

“I felt very at home in California, but the place is prone to earthquakes, and the one in 1944 scared the life out of me. For months afterwards, I felt that every time I sat down, I should have to put on a seatbelt.” Earthquakes are when tectonic plates slip past each other causing a “snap’. The ground shakes violently and can even crack. Though the occurrence of an earthquake is dreadful, familiarizing yourself with the causes and effects can be useful, and in turn make it less scary.

Light is electromagnetic radiation, energy shown as a wave or a particle, that can be visually perceived as radiant energy.1 Light is measured by the wavelength and frequency. A wavelength is the distance from any point on one wave to the same point on the next wave and shown by lambda, λ.2 The different types of light begins with gamma rays and proceed to radio waves when increasing wavelengths are compared. Frequency is the number of crests per second and is expressed in hertz and shown as v. The pattern associated with light is indirectly related to the wavelength. The variability of light starting with gamma rays and ending with radio waves is connected by decreasing frequency. Frequency is independent of the wavelength and are both

The energy originates from the hypocenter which is usually deep below the earth’s surface. The epicenter is exactly above the hypocenter. There are three types of waves which occur during an earthquake: compressional (P) waves, seismology (S) waves, and surface waves. There are four different types of fault lines which include: normal faulting, reverse faulting, and strike slip, oblique slip. Earthquakes have different consequences on different landscapes. Some earthquakes cause surface faulting which appears as a crack on the ground. It is possible for ground failure to occur which can generate liquefaction, lateral spreads, landslides, etcetera. Depending on the location of the earthquake, it can cause secondary threats such as tsunami, building fires, dam failures and other disastrous

I have read many books on seismology and am fascinated about the geology of our planet and the Gaia theory. (That our planet is alive and moving) I think the class will find the topic interesting because everyone lives in the Bay Area and will be directly affected by a major earthquake in the Bay Area. The three main points I will discuss are: 1) What are earthquake Faults? 2) Which Fault in the Bay Area is the most dangerous, and 3)

Earthquakes are one of the most destructive natural disasters. They destroy buildings, collapse roads and bridges, change landforms, and have cause millions of deaths throughout the years.

Earthquakes have been a serious trouble in our lives for as long as people have inhabited the earth. These natural disaster such as earthquakes that happen on the earth have been the cause of many deaths in the past century. What can be done about these violent earthquakes that take place nearly without warning? Predicting an earthquake until now has almost been technologically impossible. However, with improvements in technology, more lives have been saved and much more will. All that remains is to research what happens place before, during, and after an earthquake.

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault of fault plane. The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. There are four types of earthquakes tectonic,volcanic,collapse,and explosion. Another good topic to study is deeper into the science of earthquakes. ”Most earthquakes occur along faults, or breaks, in the Earth's crust.” by Bill Haneberg.http://tremor.nmt.edu/faq/what.html

B. As stated by Classic (2011), radiofrequency can be categorized as a wavelength and a frequency. a. Classic (2011) defines wavelength as from one peak point to another as one complete

“Do not go gentle into that good night, / Old age should burn and rave at close of day; / Rage, rage against the dying of the light” (Thomas, 1951). These words spoke volumes when I first heard them in the motion picture, Interstellar. It can be interpreted in several different ways, however, to me, it simply means don’t give up. Don’t stop learning; don’t stop working. Rage against the obstacles, unfortunate circumstances, and the end of each day. Each day brings opportunities to accomplish something new or to progress on any tasks, projects, or goals. I try to keep this state of mind as I continue to go through life. Currently, my life consists of work, college, adult responsibilities, and leisure. I always grant myself time at the end of

While tracking all of Earths major earthquakes and volcanos there became trends that developed. These trends allowed me to actually learn from our own Earth. The most active area of our plate tectonics was subduction zones. This type of plate boundary was the reason for the majority of the earthquakes documented over the semester. Most of these earthquakes were shallow, but at times had very deep focal points. Because of the old, cold plate being sub ducted I saw significantly more deep focus earthquakes in this tectonic setting. Subduction zones were also responsible for the deepest earthquakes that were experienced throughout the semester. While capturing the title of the most active, deepest earthquakes, it also produced the largest earthquakes of the semester. Subduction zones accounted for nearly all of the earthquakes that registered a magnitude above 5.7. Because of these earthquakes being the largest, they also created the most damage. These plates were able to cause the most damage because of how much elastic energy they could store in their old, cold, and brittle plates. There were several earthquakes throughout the semester that took the lives of the people living in the area while causing destruction on their community infrastructure.
