Earthquakes can happen along any type of plate boundary. The most common form of earthquake is the tectonic earthquake; it happens when the shifting of the Earth's plates is driven by geological force. Strike-slip earthquake, an earthquake where two tectonic plates sliding past each other get caught, build tension, then slide free, creating an earthquake. This seismic activity is used by scientists to monitor volcanoes. This is an excerpt from a Curiosity Stream program on tectonic plates and earthquakes. 3.4 - 4.0 g/cm^3 Describe the mesosphere strong lower part of the mantle. No, earthquakes of magnitude 10 or larger cannot happen. Understanding how these earthquakes function includes grasping both the scientific causes and human effects. There are four major types of earthquakes, which are;-Four Types of Earthquakes 1. It seeks to understand which faults are responsible for seismic activity in an area by analysing a combination of regional tectonics, recent … Faults or Fault Plane: Fault A fault is a rock fracture where the two sides have been displaced relative to each other. A sudden movement of the Earth's crust. Plates do not always move smoothly alongside each other and sometimes get stuck. During an earthquake, the rock on one side of the fault suddenly slips with relative to the other. The magnitude of an earthquake is related to the length of the fault on which it occurs. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other. Tsunami A giant wave (or series of waves) created by an undersea earthquake, volcanic eruption or landslide. A tectonic earthquake is the result of two are more tectonic plates colliding or side swiping each other.

An obvious one is the 1811-1812 earthquakes at New Madrid, Missouri, and another is the 1886 earthquake at Charleston, South Carolina. A sudden shaking of the ground when stressed rocks move along a fault. Crust, Mantle, Core. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. According to the theory, a tectonic Tectonic Plates. These are the most occurred earthquakes worldwide and are usually occur at the boundaries of the tectonic plates. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. An earthquake is a sudden vibration of the earth surface due to the rapid release of stored energy between tectonic plates. There seems to have been a lot of big earthquakes lately. n.
