Strong earthquake tremors have been felt in Papua New Guinea. Its magnitude has been measured at 7.7 on the Richter scale. After the earthquake, there has been a stir in the surrounding areas. People rushed out of the house. A tsunami warning has also been issued by the US Geological Survey. Due to the magnitude of the earthquake, there is also a possibility of heavy damage. Let us tell you, Papua New Guinea, a country in the Pacific Ocean region near Indonesia, is very vulnerable to earthquakes. The epicenter of the quake was in Lai, about 60 km from the capital, Port Marsebay.
Know why earthquakes happen?
Earth is mainly made up of four layers. Inner core, outer core, mantle and crust. The crust and upper mantle core are called lithosphere. This 50 km thick layer is divided into several sections called tectonic plates. These tectonic plates keep on vibrating in their place and when this plate vibrates too much, an earthquake is felt.
Know what does the epicenter and intensity of an earthquake mean?
The epicenter of an earthquake is the place just below which the earth starts to shake due to the movement of the plates. The impact of earthquake is more in this place or its surrounding areas. If there is an earthquake with a magnitude of 7 or more on the Richter scale, then the tremor is stronger within a radius of 40 km around.
