There are three types of tectonic plate boundaries: Plates rip apart at a divergent plate boundary , causing volcanic activity and shallow earthquakes; At a convergent plate boundary , one plate dives (“subducts”) beneath the other, resulting in a variety of earthquakes … The science that studies earthquakes is known as seismology. A tectonic earthquake is one that occurs when the earth's crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes. Normal and reverse faulting are examples of dip-slip, where the displacement along the fault is in the direction of dip and movement on them involves a vertical component. Earthquakes Earthquakes are the result of forces deep within the earth's interior. There are four different types of earthquakes: Tectonic, volcanic, collapse and explosion. Depending on how deep an earthquake is and the type of fault it takes place on, earthquakes can be minor or major, close to the surface or deep within the earth. https://discover.hubpages.com/education/Types-Of-Earthquakes The Puget Sound has the potential to experience three different types of earthquakes… By a close analysis of the record of P and S waves, the thickness of the earth’s crust and its variation in different parts of the earth can be calculated. Seismologists categorize Cascadia region earthquakes into 4 different types, depending on where they occur, (their "source zones"). It is worth remembering that the epicenter of an earthquake can be located when its distance from the three conveniently placed stations are known. Earthquakes at the bottom of the sea or ocean create a series of waves that result in a destructive tsunami. The world's major faults are located on the fringes of the huge tectonic plates that form the earth's crust. / Types of disasters / Geophysical hazards: Earthquakes. Text size: -A A +A. These are the most numerous type of earthquake in Hawaii. Submarine Earthquakes can also cause damage to communication cables (submarine) and bring disturbance in internet connections. There are three main types of fault, all of which may cause an interplate earthquake: normal, reverse (thrust) and strike-slip. The term earthquake is closely related to earth movements. Types of Earthquakes in the Puget Sound . All of these earthquake types can be Big Ones. Earthquakes occur most frequently along geological faults, narrow areas where rock masses move with each other. There are two main types: Minor to moderate earthquakes (up to M5) occur on upper crustal faults beneath and within the volcanoes. Because shallow fault earthquakes are so near the surface, even small ones cause a lot of damage from shaking. Earthquakes often occur in regions away from fault lines. Earthquakes involving slippage along tectonic faults comprise the second class of seismic sources in Hawaii. However, earthquakes don’t always occur naturally and there are several manmade causes also for their occurrence. There was a major quake on this Seattle fault about 1,100 years ago. Earthquake Fault Types. Three types in particular, Cascadia Megathrust, Deep Intraplate, and Crustal Faulting earthquakes, may occasionally produce strong shaking that can threaten life and property.
