Strong tremors of earthquake have been felt in the island of Mindanao, Philippines. According to the National Center for Seismology, the magnitude of the earthquake was recorded at 7.1 on the Richter scale. According to the information received, the depth of the earthquake was measured to be 49 km, while its center was about 695 km north-northeast of Sulawesi, Indonesia.
The US Tsunami Warning System has issued a warning due to the earthquake. According to reports, no loss of life or property has been reported so far due to the earthquake. If we look at the history of earthquakes in the Philippines, there was a terrible earthquake in the month of October 2013. An earthquake of 7.2 magnitude was then recorded in Bohal Island, in which about 220 people died. According to UNICEF, more than 50 thousand houses were destroyed in this earthquake.

Why does earthquake happen?
Earth is mainly made up of four layers. Inner core, outer core, mantle and crust. The crust and upper mantle core are known as lithosphere. This 50 km thick layer is divided into several sections. These are called tectonic plates. These tectonic plates keep moving in their places. When this plate starts moving too much, it is called an earthquake. These plates can move from their place both horizontally and vertically. After this, she looks for her place while remaining stationary, during which one plate comes under the other plate.
The intensity of an earthquake is estimated by the waves of energy emanating from the epicenter. These waves vibrate for hundreds of kilometers and even fall into the cracks in the earth. If the depth of the earthquake is shallow, then the energy released from it is very close to the surface, causing terrible destruction. But the earthquakes that come in the depths of the earth do not cause much damage on the surface. High and strong waves arise when an earthquake occurs in the sea, which is also called a tsunami.
