Self-help knowledge of earthquake disaster

Earthquake and its definition

Earthquakes, also known as earthquake and ground vibrations, are the vibrations that occur during the rapid release of energy from the earth's crust and are a natural phenomenon of seismic waves. The collision and collision between plates and plates on the earth, resulting in faulting and rupture within the plates, edges and plates, is the main cause of earthquakes.

The place where the earthquake started was called the hypocenter, and the ground just above the epicenter is called the epicenter. The most severe ground vibration of a destructive earthquake is called a "polar earthquake zone", which is often the epicenter of the earthquake. Earthquakes often cause heavy casualties, which can cause fires, floods, poisonous gas leaks, bacteria and radioactive materials, ... [More]

When the rainstorm or snowmelt occurs in the basin, the runoff is gathered at the exit section of the river according to its distance. As the nearby runoff arrives, the flow of the river begins to rise, and the water level rises accordingly. When most of the high intensity surface runoff reaches the exit section, the maximum discharge is called peak flow, and the corresponding maximum water level is called the peak water level. At a certain time after the storm has stopped, the river surface runoff and the amount of water stored in the ground, ... [More]
