Vancouver Vancouver – Places of Interest 1. Seawall The Seawall in Vancouver was constructed to protect the foreshore of Stanley Park from eroding. The Seawall is spread over almost nine kilometers and has a paved route along the way. The construction began in 1917 and was completed only in 1980. It is an ideal place to go for a stroll while enjoying the waterfront views. The Seawall is a preferred spot for jogging and cycling. The location of the Seawall and the views it offers has made it the…

1.1 Introduction to Landslide A landslide is a geological phenomenon, which includes a wide range of ground movements, such as deep or shallow failure slopes and rock falls. See figure 1.1. 1.1.1 Factors influence Landslides Landslides occur when the stability of the slope turns from the stable state to unstable state. Most of the Landslides usually cause depend on two main factors: (i) Natural Factors and (ii) Anthropogenic Factors. (USSG, 2004) (i) Natural Factors (a) Geological…

Maule Earthquake One of the largest Earthquakes in the world occurred on February 27, 2010. This Earthquake, known as the Maule Earthquake, took place on the offshore of Bio-Bio Chile with a magnitude of 8.8 (“Aftershocks of Chilean Earthquake”). Even with all the damage and destruction caused by the earthquake, the offshore of Bio-Bio, Chile was in for more destruction by the tsunami that shortly followed Maule Earthquake. As a result, Chile was impacted by the earthquake politically,…

Topic Suggestion #1: Natural Disasters and How to get Ready for It Analysis: Self: I often worry about natural disasters because I live right on the San Andrea’s Fault. Also, when I see the world news, I always hear that many people died because of natural disasters. I experienced many earthquakes, but my family was not ready for earth quakes. We do have emergency foods and lights, however, most objects in my house will fall once a major earth quake starts. When I was in middle school, around…

Kennedy (1964) to designate the peak of a wide spread orogenic thermo-tectonic episode characterized by intense period of reactivation and crustal formation. The term Pan African Orogen was used to describe the structural differentiation of Africa into cratons and mobile belts during the Neoproterozoic to earliest Paleozoic time (Kennedy, 1964). However, Kröner (1984) reformulate the term Pan-African to describe the tectonic, magmatic, and metamorphic activity of Neoproterozoic to earliest…

Most of Costa Rica is dominated by the Sierra Madre mountains, literally fractured into individual ranges and valleys by violent volcanic eruptions over eons of time. Guatemala, except for the coastal areas, is a mountainous country of rolling hills, plateaus, deep river valleys, and numerous volcanoes – some still active.Speaking of volcanoes , Costa Rica’s most active one, located in the Tilaran Mountains erupts in some measure almost every day. To the southeast, the Poas, Barva, Irazu and…

Pangea! It was the supercontinent that existed about 300 million years ago. According to Alfred Wegener’s theory, long before us humans existed all of the continents used to be one large landmass. Who is Alfred Wegener you might ask? Alfred Wegener was a German polar researcher, geophysicist, and meteorologist born in Berlin on November 1, 1880. I chose to research about Alfred Wegener’s life and his struggles because we are currently focusing on the continental drift theory in science class. He…

The Liberty Hill pluton of South Carolina is one of twenty-four known granitoid bodies along the southern Appalachian Piedmont which possess the properties of a supergroup as described by Pitcher. The country rocks surrounding the plutons are at least mid-Paleozoic in age. Liberty Hill lies within country rocks of the Carolina Slate belt which consists of “primarily intermediate to felsic pyroclastic debris and hypabyssal intrusive bodies.” (Speer et al. 1980). The isotopic ages of…

Disasters are catastrophes that have impacted many places and people. Two examples of disasters are the Japanese Tsunami and the Peshtigo Fire. The tsunami that struck Japan was a tragic event that destroyed many homes, buildings, and vehicles. After an earthquake hit, a tsunami, or a very long and high wave, formed along the coast. The wave came and destroyed many cities and towns. The Peshtigo fire was a fire that occurred in 1871. Many fires happened for the previous days and then one night,…

earthquake is the phenomenon that a huge energy suddenly released and appeared in the Earth’s crust when two moved plates slip past one another. The earthquakes usually happen in the convergent boundaries, divergent boundaries and transform boundaries. In the three kinds of boundaries, the convergent boundary often produces the largest magnitude earthquakes. Because when the two plates collide strongly in the convergent boundary, the extreme pressure and the great friction will appear. So the…
