How Does A Plate Boundary When Earthquakes Occur

This lab uses earthquake data to construct profiles of two convergent boundaries: the Tonga Trench and the Peru-Chile Trench. Where two tectonic plates converge, if one or both of the plates is an oceanic lithosphere, a subduction zone will form. When crust is formed at a mid-ocean ridge, it is hot and buoyant meaning it has a low density. As it spreads away from the ridge and cools and contracts, or becomes denser, it is able to sink into the hotter underlying mantle. When two oceanic plates collide, the younger of the two plates, because it is less dense will ride over the edge of the older plate. The density of the

Be sure to consider topography/bathymetry as well as the earthquake and volcano layers. List several ways and be specific. 3pts In the middle between the two Without the plate boundary feature, you would still see the change in depth where the mountains are, still feel earthquakes, and see volcanic eruptions. Adapted from an activity by Laurel Goodell February 2013

The earthquake occurred on the 12th of January 2010, a slip along the conservative boundary situated along Haiti caused a significant earthquake with subsequent damaging aftershocks. As can be seen in figure 1 the shaking intensity was strongest at the epicentre of the

​The claim that is correct is claim 3. The Jalisco Block is convergent to the Rivera Plate and divergent from the North American Plate which best explains the patterns of Earthquakes and Volcanoes on the Jalisco Block. I believe at this claim is correct because fro any plates to be convergent to one plate, they must be divergent to another plate. This case happens for the Jalisco Block. The card that support this statement is card A which tells us that scientists found the same rock on either side of the Tz Rift Zone where they were originally formed a team he same time at the same place when today they are 24 km apart. This matters because it shows that there is volcanic activity at divergent plate boundaries and it also proves the the

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

In conclusion the recent conception and development of plate tectonic theory has greatly aided our understanding of the distribution of seismic events. We now understand that there is a correlation between earthquakes/volcanoes locations and their proximity to a plate boundary plates are continually moving and earthquakes and volcanoes are found along these boundaries. Exceptions to this rule such as Hawaii also help prove tectonic theory due to their unique creation. Whilst this has helped our understanding we also recognise the fact those in LEDCs with poor access to education are unaware of plate tectonic theory so they cannot understand the hazards that some countries face, nor have the means to mitigate against them thus worsening the

I am comparing the 2010 Haiti Earthquake and 1989 Loma Prieta Earthquake. The type of plate boundary for the Haiti Earthquake is a transform plate boundary. However, for the Loma Prieta Earthquake, it is a divergent plate boundary. The tectonic plates that were involved for both were the North American Plates, but the second plates are not the same. The Caribbean plate was the second plate for the Haiti earthquake and Pacific plate was the Loma Prieta earthquake. The depth and magnitude of the earthquake is related to the plate tectonics, because it allows us to determine the type of plate boundaries the earthquakes are with the data of the depth and magnitude of the earthquakes. The Haiti earthquake is a crustal fault type and the Loma Prieta

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

“The Really Big One” is an article by Kathryn Schulz about the Cascadia Subduction Zone, a fault line that runs seven hundred miles along the West Coast. It consists of two tectonic plates where one plate is sliding underneath another. In this case, the oceanic plate Juan de Fuca is sliding under the continental plate known as the North American plate. In her article, Schulz repeats the words of seismologists and scientists alike in the opinion that the Cascadia Subduction Zone is overdue for a magnitude 9.0 or higher earthquake and resulting tsunami. No one in the Pacific Northwest is prepared for it. With historical stories and examples from around the world Schulz warns of the damage to be done when the “Really Big One” finally makes itself known.

The tectonic setting for the 1906 San Francisco Earthquake was in the outermost shell of earth consisting of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the principal one being the San Andreas fault. The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accommodating horizontal relative motions (usgs.gov).

Moving on to Block Mountain, this mapping area has four main folds and six significant faulting components, all resulting from continued compressional tectonics. The oldest structure, which is the Sandy Hollow anticline, is a northward-plunging anticline that is similar in age to the eastern syncline underlying the

Earth's plates and continents do not always just stay in one place. They shift, collide, and move apart, causing destruction in many different parts of the world. The movement of plates causes volcanic eruptions, changes in the oceans, and perhaps the most dangerous of all, earthquakes. Earthquakes may have the most devastating effects on people and cities.

Ironically, most of the greater civilizations were clustered along the seismogenic tectonic boundaries and succumbed to their wrath. The environmental characteristics of different civilizations varies depending upon the water resources available, soils, topography and shores. The distribution of ancient sites (Mycenaean, Greek, Aegean, Corinth and Rome) along the African-Eurasian plate boundary were associated with the southern shore of Mediterranean and other north-eastern shores. Interestingly the trade routes that connects the civilizations from east to west mimics the tectonic boundaries. The reason could be the civilizations located near to the tectonic boundaries offer different cultural character than those which were far away and also

Scientist are struggling to come up with a widely accepted model that will explain the role of non-vertical strike-slip fault segments, crustal movement and deformation within Pacific –North American plate boundary. Multiple methods of analysis are being used; some of which are described below.

Volcanoes and Earthquakes are two of the most intriguing natural disasters that can occur on earth. Unlike hurricanes and tornadoes, they can awaken at almost any point in time throughout the year. These two natural disasters are also different from others because they occur on the layers of the earth itself. Volcanoes, while large to us, are actually small, conical patches of earth that spurt and ooze hot molten lava from the core, and can destroy areas of land triple their size. Earthquakes, on the other hand, are severe jolts felt on land due to the movement of earths tectonic plates. Some may describe earthquakes as being similar to riding a bike down a flight of stairs. The impact of an earthquakes can take down even the largest buildings and strongest structures. All natural disasters can have damaging effects on land, some more than others, and all can be measured or predicted in different ways. Although earthquakes and volcanoes are similar to each other, the two are still very comparable. A few of these similarities and differences include the cause of their occurrence, and how their occurrence impacts the environment.
