into three major categories: The first type is shallow or crustal earthquakes which are caused by rupture of the faults in the North American Plate. The Scott Mills earthquake happened in 1993 and it occurred in the Willamette Valley. The second type is deep or intraplate earthquakes are caused by rupture faults within the subducting Juan de Fuca Plate, deep earthquakes are often the most damaging type of earthquakes. In 2001, a deep earthquake named the Nisqually hit the Puget Sound area of
the plate boundary between the Pacific tectonic plate and the Juan de Fuca tectonic plate. The plate boundary is a divergent plate boundary, meaning that the two plates are slowly pulling away from each other. This causes a gap to be left behind in the ocean’s crust. Magma from deep below races to fill in the gap. Once the magma reaches the ocean water, it is cooled into a solid
perspective as to what was going on, through out the rest of this process. Most mountains are created by plate boundaries. Either by continental collisions, or subduction zones at plate boundaries usually create mountains. The Rocky Mountains were not, though. These mountains were formed away from plate bo... ... middle of paper ... ... plate is now called the Juan de Fuca plate (“Juan de Fuca General”). This happened just before the Laramide orogeny contributing to the building of this huge landmass
Understanding the plate tectonics theory is very important, especially when investigating natural disasters like earthquakes, and volcanic eruptions. It is also gives scientists the ability to understand how mountains were formed between two tectonic plates. There are three types of interactions between plate boundaries: convergent, divergent and transform. Looking back at the history of these three different interactions, earthquakes, like the one in Haiti, volcanic eruptions, like at Mount St.
the world are all separated by different tectonic plates which when collide is called Tectonic Activity. There are different forms of tectonic activity and different processes and landforms, which are involved during and as a result of the collisions. As and when these collisions are going to take place we can't determine because current technology hasn't allowed us to dig as far into the earth to the point of pressures which causes the plates to collide. These pressures are believed to be eruptions
This volcano has three different summits; they are Columbia Crest, Point Success and Liberty cap, the highest which is 14,411 feet and the lowest which is 14,112 feet. It lies on the Juan de Fuca Plate. This is a divergent boundary. It was formed by the subduction of the Juan de Fuca Plate and the North American Plate. This volcano also has lahars which are large mudflows that happen in the deposits of sediments that surrounds volcanoes; they can be hot or cold. This volcano includes but not limited
A volcano is a mountain or hill, which has a vent where lava, broken pieces of rock, hot vapor, and gases are being erupted from beneath the Earth’s crust. It is unknown where the first volcano was located; however, the first one recorded was Mount Vesuvius in Naples, Italy. The ash and rock from that particular eruption engulfed Pompeii, making it hard to breath. Eventually, the ash was turned to mud from the rainfall, which soon buried it. It was said that some people were able to successfully
I decided for my project that I would spend the time researching Mount Baker. Mount Baker is located about 30 miles east of Bellingham, Washington. The Cascade Mountain range extends over 140 miles between Seattle, Washington and Vancouver, Canada. Mount Baker is a Stratovolcano, which is also known as a composite volcano, it is also the highest peak in the North Cascades and the fifth highest in the Cascade mountain range (Volcano Hazards Programs). Cities located near Mount Baker include Abbotsford
Mount Shasta Term Paper Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion
Ashleigh Bibby Dr. Gros Physical Geography 1114 25 April 2014 Climate and Weather: Chances are if you are visiting Cabo San Lucas, Mexico, it will be warm and sunny. Averaging over 350 days of sunshine, Cabo is known for warm weather and very little precipitation. Some things that affect the climate and weather of Cabo are: • Latitude- Cabo is located at 22 degrees North latitude, so its warm year round temperatures are a result of its closeness to the equator. • Proximity to Oceans- Cabo is located
movement of the plates, the stress forms along the fault and ultimately releases as an earthquake. On the pacific plate, Transform boundary along with the San Andreas fault. Transform-fault boundaries is when two plates that slide horizontally past another. Transform boundaries are usually found on ocean floor, but a few occur on the land. San Andreas fault zone is a transform fault, which connects East Pacific rise, in the south a divergent boundary, with South Gorda-Juan de Fuca-Explorer Ridge,
The result of these gaps overtime, lead scientists to make assumptions over what happened. Kamiak Butte is found on the North American Plate, and does not seem to be located near any plate boundaries, other than the Juan de Fuca Plate, which is located near the west coast. This is a reason as why the Palouse has no dominating mountain forms, such as the Cascades, which are a result of oceanic-continental convergent boundaries. Kamiak
Tectonic Plates and its Effects on the Physical Face of the Earth For millions of years, tectonic plates have been determinate of changes in the physical face of the earth, and they continue to do so today. These massive plates move underneath the surfaces of the oceans and the continents, producing earthquakes, volcanoes and uplifts. This paper will discuss the composition, movement and history of tectonic plates, the theory of plate tectonics and its history, and tectonic plates affect the surface
Lassen National Park lies at the southern most part of the Cascade chain volcanoes. Its volcanism is driven by the subducting Juan de Fuca plate, where most of the Cascade chain volcanoes derive their magma. Bumpass Hell is the most attractive area with multiple surface pools that demonstrate the hydrothermal heat that lies beneath the surface. The vapor permeated zone dominates the
years. However, the driving mechanism of tectonics forces still remains a mystery. The asthenosphere on which the lithosphere floats is molten due to radio-active decay warming us from the inside out. Volcanism is one result of moving plate margins. Specifically where plates spread apart, volcanoes and subsequently some of the largest mountain ranges on earth can be found. Hydrothermal vents are also founds at these location. What wasn’t understood until this dive was a hydrothermic cycle that created

closely linked with the positioning of the tectonic plate boundaries across the globe. Today there are about 500 active volcanoes in the world. The world map of volcanoes in your atlas shows that the most volcanic activity occurs along the West coasts of North and South America, (along the Rockies and Andes) and the coasts of many Far East countries (in areas like Japan, China etc). The positioning of these volcanoes coincide with major plate boundaries. E.g. the volcanoes along the West coast
