Hello. I’m going to talk about earthquakes.
Do you know anything about earthquakes? I’ll talk about how earthquakes happen.
The strong force of compression works on the Japan Islands. Because plates from the pacific and the Philippine Sea move toward Japanese Islands, and plate sink under Japan. Along with this, various types of earthquakes occur.
There are Primary-wave and Secondary-wave as regards an earthquake.
The first wave is abbreviated to P-wave. Wave coming next is abbreviated to S-wave. P-wave trembles with lengthways. S-wave trembles with crossways.
