Many people died in earthquake and tsunami in Palu city in Indonesia. The tsunami was followed by a magnitude 7.5 magnitude earthquake in Palu, Sulawesi island, on Friday at the local time of Friday evening. About six meters (20 ft) high waves created by the tsunami float the city.
Earthquake and tsunami caused thousands of homes to collapse. But this tsunami has caused a lot of sci-fi to the scientists. Emergency rescue workers and scientists are trying to find out the reasons for such a large wave.
Experts say this is the biggest earthquake recorded worldwide this year. A magnitude 7.5 magnitude earthquake struck on Friday (September 28th) in the world's 11th largest island Sulabaseer Palu. There was a wave of fierce tsunami after it shook. The coastal area lounges high waves
AFP reported that geologists have called it 'strike-slip' event, so that the crust is changed horizontally. This type of movement is usually not a tsunami. In this incident, the eastern flank of the island's fault went northwards. Although tsunamis in such a case, it does not usually appear in waves of six feet height. But after the earthquake of Indonesia, a huge wave struck the people of Palu.
Analysts said that large scale transit changes will occur in the sea due to the creation of large waves in a few quarters. That is to say, the occurrence of vertical movement can speed up the entire water level, and then the water can run on any side. Some initials can be seen, that the displacement occurred in the sea, it is notable enough to make such a big wave. What is the reason for such a big wave?
Researchers say that this event can happen due to earthquake caused by landslides below the water. It can hit a large wave on the beach.
Mohammad Haiderajadeh, assistant professor of the University of Brunnel in the UK, said, "My calculations say that sea level distortion can be up to 49 centimeters due to earthquake. It can be a tsunami up to a meter maximum. But not up to six meters. Something else can happen. Possible two reasons are huge landslides and funnel created in the Gulf. It is necessary to conduct a physical test to understand the change. '
Dave Petley, a landslide expert at Sheffield University, said that according to the photographs of artificial satellite, the mass of the house was centered in a small area. A huge area of land was empty. There was settlement in the area earlier. This phenomenon is called liquidation, so that the structure of the earth is broken and the active landslide is created. The effect of monitoring the area can be understood.
