Papua New Guinea lies on the Ring of Fire, an arc of seismic faults around the Pacific Ocean, where most of the world's earthquakes and volcanic activity occur. But there were no tsunami warnings or immediate reports of damage, officials said.
7 plates rotate inside the earth
According to the information, there are 7 plates inside the earth which are continuously rotating. The place where these plates collide is called the fault line zone. The corners of the plates bend due to repeated collisions. Then when the pressure becomes too high the plates begin to break. As they break, the energy inside finds its way out. After this disturbance an earthquake occurs.
maximum intensity of earthquake
However, the maximum intensity of the earthquake has not yet been determined. However, earthquakes with a magnitude of 7.0 or more on the Richter scale are considered dangerous. On this scale, earthquakes of magnitude two or less are called microquakes, and are mostly not felt. An earthquake of 4.5 magnitude can damage houses.
