Seism is a violent shaking of the Earth’s crust that may cause destruction to buildings and results from the sudden release of tectonic stress along a fault line or from volcanic activity. Earthquakes strike without warning‚ so it is important to know safety measures and act now to be prepared. Before the Shaking Starts Prepare Your Family •Know the safe spots in each room― against inside walls‚ under sturdy tables‚ desks or archways. • Know the danger spots― windows‚ mirrors‚ hanging objects

Earthquakes and Logarithms Earthquakes are responsible for a wast majority of natural hazards on our planet. This natural geological phenomena are almost impossible to predict‚ and they occur usually in zones of the planet that are prone to movement in the uppermost crust of the earth. Certain areas are more likely to experience earthquakes‚ and also the aftermath of the earthquakes can be just as destructive or sometimes even more. Different methods of measuring earthquakes have been implemented

Effects of earthquakes Shaking and ground rupture Shaking and ground rupture are the main effects created by earthquakes‚ principally resulting in more or less severe damage to buildings and other rigid structures. The severity of the local effects depends on the complex combination of the earthquake magnitude‚ the distance from the epicenter‚ and the local geological and geomorphological conditions‚ which may amplify or reduce wave propagation.[44] The ground-shaking is measured by ground acceleration

Would earthquakes of similar magnitudes in different populated regions of the Earth cause approximately the same levels of damage? In your discussions‚ consider both geologic and human-induced factors. The amount of damage caused by an Earthquake does not solely depend on the magnitude of the Earthquake. Factors such as population‚ geographic location‚ soil type‚ and the type of building material commonly used for construction in a region determine the extent of damage caused. If an Earthquake strikes
