What is the record obtained from measuring an earthquake called?

Instrument Used:
Earthquakes are measured using a device called a seismograph (or seismometer).

A seismograph detects and records the vibrations (seismic waves) produced by an earthquake.

It consists of a mass suspended on a spring with a pen attached, which records motion on paper or digitally.

Seismogram:

The actual record or graph produced by the seismograph is called a seismogram.

It shows the arrival times and amplitudes of different seismic waves (P-waves, S-waves, and surface waves).

By analyzing seismograms from multiple locations, scientists can determine the epicenter, depth, and magnitude of the earthquake.

Importance:

Seismograms are crucial for earthquake research, early warning systems, and understanding Earth’s internal structure.

They help distinguish between natural earthquakes and other seismic events (like explosions).

Answer: The record obtained from measuring an earthquake is called a seismogram.
