YOGYAKARTA - Indonesia is in an earthquake-prone area, both tectonic and volcanic earthquakes. Earthquakes that occur can be light and large forces whose impacts are severe. The strength of the earthquake can be measured or recorded with a device called seismograph. So what is the way the tool works to record earthquakes?
The seismograph is a tool used to record and measure earthquakes. This tool serves to detect vibrations that occur due to the movement of earth plates.
The seismograph was first developed by Chinese scientist Zhang Heng in 132 AD, although the modern version was only developed in the 19th century by Western scientists.
The seismograph recorded an earthquake and produced a seismogram, which is a curve-shaped graph recorded on paper. According to the Encyclopaedia Britannica, seismographs are tools that record seismic waves caused by earthquakes, explosions, or other seismic events.
By using a seismograph, you can find out the strength, duration, direction, and distance of the earthquake. This tool works with two main methods, namely horizontal and vertical recording.
The seismograph is a tool used to measure earthquakes. This tool is different from seismometers, where seismographs function to record earthquake activity, while seismometers are used to detect the presence of earthquakes.
Seismographs have a very important role in the world of geophysics and disaster mitigation. Here are some functions or uses of seismograph tools:
The seismograph works based on the principle of inertia, namely the tendency of stationary objects to remain silent despite interference from outside. In general, the way seismograph works can be explained as follows:
Seismographs are an important tool in recording and measuring earthquakes. With increasingly developing technology, this tool continues to experience improvements to increase accuracy and speed in detecting earthquakes.
That's a review of earthquake or seismograph records. In Indonesia, the presence of seismographs spread across various regions is very helpful in monitoring seismic activity and providing early warnings for the community. Also read what to do when an earthquake occurs.
