An earthquake occurred on March 11, 2011. It was measured as a 9.0 earthquake according to the Richter scale. It occurred 500 kilometres off Japan’s coast. The epicentre was near Sendai in Japan. It was 32 kilometres below water level. (EARTH Magazine, 2011)(Japan Tsunami 2011, 2019)Japan sits on top of four different tectonic plates which cause the island to deal with 1,500 earthquakes annually. Japan is located in the Ring of Fire, which is a place where many earthquakes and…...

Volcanoes and mass movement are two very different geological events that support the same ideas but these ideas are created in different situations. These situations then tend to link the to together because of the actions of the volcano when it erupts and causes mass destruction. Volcanoes have many hazards but these hazards only really become hazards if humans are near to the volcano if there were no humans then there would be no threats and no hazards. The first main…...

The weakness of Wegner’s theory

Introduction While the ancient fossils on different continents were often similar or identical, the exploring naturalists were finding out that living plants and animals on the different continents were often very different. The naturalists were discovering whole new groups of animals and plants on nearly every island and continent they visited. Most biological species seemed to be unique to the region or continent in which they were found. How could these seemingly contradictory observations be reconciled? Plate tectonics provided the…...

I needed to investigate the evidence that erosion was still taking place on the north beach . In order to perform this, I measured the width from the old pillbox to the bottom of the cliff. I used a measuring tape. The measurement was very relevant because knowing this would help validate how far the cliffs were retreating over a span of years. An issue in collecting this data was that we could not walk directly onto the slump, for safety…...

Faults, Folds and Maps of Geology
Words • 633
Pages • 3
There are different phenomena happening in the earth’s crust and some of those are the occurrence of folds and faults. Both phenomena are caused by forces like tension and compression. Folds are bends in the rock surfaces while Faults are fractures in the earth’s crust which allows blocks of rocks to move relative to one another. When this movement becomes rapid, it results to earthquakes ("What is a fault? ," 2008). Since there are two blocks of rocks involved in…...

What is an earthquake? The definition of an earthquake is a violent vibration of the Earth that is caused by the sudden release of energy, usually as a result of faulting, which involves the displacement of rocks along fractures. They occur when rocks have been placed under huge amounts of pressure, for example if you take the rocks in the lithosphere, if the pressure increases very slowly, they will deform slightly. However, the problem is that all solids have a…...

What is Earthquakes?
Words • 212
Pages • 1
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth’s lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. The seismicity, or seismic activity, of an area is the frequency, type and size of earthquakes experienced over…...

The energy stored on the earth’s surface is emitted as earthquakes occur. When earthquakes are more frequently correlated with earth surface shifting, minor earthquakes may also occur far from plate margins. Some earthquakes are frequently connected to rock fault lines. Shock Waves Once energy is absorbed onto the earth, shock waves are going in either direction. The deep stage where the rapid activity is taking place is considered the focal point. The epicentre is the location where the shock waves…...

The transitional relation between the lapilli-bombs agglomerates and clastogenetic lava (Fig.12B)proposes that theemitted lava blebs for each lava was virtually continuous throughout a singlefountains episode. Likewise, each eruptive unit has its own cooling joints.The occurrence of inversely coarse-tail-graded beds, poorly defined bedding, lithic clasts and lapilli/bombs-rich concentration zones are indicative of an emplacement of the lateral flow, akin to pyroclastic density currents forming spatters ( Freundt and Schmincke, 1995; Valentine et al., 2000).

Introduction According to Pettijohn, Potter and Siever (1972), diagenesis refers to all physical and chemical processes that are part of post-depositional connected to newly deposited grains/sediments before metamorphism's realm begins. Although there is no clear knowledge of the limits between diagenesis and metamorphism one can argue that diagenesis takes place at temperatures below 250 degrees, at pressures below 1000 bars and at maximum depths of 30 km. Fig.1: Realm of diagenesis based on temperature and depth According Manzoor (2017), the…...

The Archeozoic Era stretches from about 3.8 billion to 2.5 billion years ago. Traditionally, the beginning of the Archean is defined to coincide with the oldest rocks discovered. As recent discoveries have pushed back the earliest dated rocks to about 4.0 billion years old, the beginning of the Archean has also been pushed back correspondingly. However, most texts still continue to date the beginning to 3.8 billion years ago. As the Late Heavy Bombardment (LHB) ended with the Hadean, the…...
