What Is an Epicenter?
The epicenter of the epicenter is not a point but an area. [1]
- The destruction of buildings is: most of the first-class houses are damaged, and a few of them fall down. Most of the Type II houses were damaged, and a few were damaged. Most Class III houses were slightly damaged and many were damaged. The not-so-sturdy courtyard wall was damaged a few times and may collapse. Archways, masonry towers and factory chimneys may be damaged. The magnitude of the magnitude 6.0-6.4 earthquake was mainly octave, which caused the following damage to the buildings: most of the type I houses were damaged, and many fell. Many type II houses were damaged and a few were dumped. Most of Class III houses were damaged, and a few were damaged (possibly with dumping). The courtyard wall was damaged and partially collapsed. Steles, etc. are often transferred or fallen. Some underground pipeline joints were damaged.
- Multilayer
- Earthquakes are strong and weak. Used to measure
- Earthquake intensity refers to the degree of damage to buildings such as the ground and houses. For the same earthquake, different regions,
- Epicenter distance--The straight line distance from any point on the ground to the epicenter is called the epicenter distance.
- An earthquake of the same size will have a greater impact or damage where the epicenter distance is smaller. Earthquakes can be divided into 3 types based on distance
- 1. Local earthquakes
- Earthquakes with an epicenter distance of less than 100 kilometers.
- 2.Shock
- An earthquake with an epicenter distance of 100 to 1,000 kilometers.
- 3. Far tremor
- Earthquakes with epicentral distances greater than 1000 km.
- A magnitude 7.3 earthquake that occurred in the Liaoning waters and Yingkou on February 4, 1975 was considered a local earthquake for the Jinxian earthquake observation station in southern Liaoning, a near earthquake for the Beijing earthquake observation station, and a distant earthquake for the Xinjiang earthquake observation station. This means that for the same earthquake to different seismic stations, the same reason applies to the same earthquake station for earthquakes in different regions.
