Method of Triangulation to Detect the Center of the Earthquake
The triangulation method is used by the Seismologist to find out the epicenter of the earthquake means the origin of the earthquake. These kind of methods can be very helpful to predict earthquakes and be prepared in advance for the upcoming disaster.
How Triangulation Method Works
There are four steps and process of Triangulation Method. Below are the steps:
- Seismograph Network: Triangulation method heavily depends upon the Seismograph Network. It is series of devices that are placed all around the globe on land area. Its functions is to record the land vibration caused by the Earthquake .
- Arrival Time Difference: The Sismograph placed all around the world record the waves in two forms, one is in P-waves and second one is S-waves generated by the earthquake. The difference between the P-waves and S-waves confirms the earthquake and the size of earthquake.
- Distance and Calculation: After the record from Sismograph P- wave and S- wave, the speed of the waves and the difference of the waves are measured. It heps to calculate the epicenter of the earthquake.
- Triangulation: After knowing data from the Seismographs, scientists can now create circles around the calculated area of epicenter. The points where intersect each other can be be the exact or near by the origin of earthquake.
Earthquakes Types
There are four main four types of earthquakes. They are Tectonic, Volcanic, Collapse, and Explosion. The horseshoe-shaped zone surrounding the Pacific Ocean has many subduction zones and is responsible for about 90% of the world’s major earthquakes countries like Japan, Indonesia, Chile, and the Philippines are located along this zone. Earthquake is a natural phenomenon. An earthquake is a sudden shaking of the earth’s surface caused by the movement of tectonic plates. Tectonic plates are large, rigid pieces of the Earth’s crust.
In this article, we will look into the meaning, types, causes, and effects of different types of earthquakes. Let’s start.
