# How is the strength of earthquakes measured?

Another way to

**measure**the**strength**of an**earthquake**is to use the Mercalli scale. Invented by Giuseppe Mercalli in 1902, this scale uses the observations of the people who experienced the**earthquake**to estimate its**intensity**. The Mercalli scale isn't considered as scientific as the Richter scale, though.A.

### What is the unit of measurement for earthquakes?

Unit 1: Earthquakes. The most

**widely**accepted indicators of the size of an earthquake are its magnitude and intensity. The magnitude is a measure of an earthquake in terms of the released energy. At the present time, the most popular scale is the Richter scale, developed by a U.S. seismologist Charles Richter in 1935.#### What is the unit of measurement for earthquakes?

**Moment Magnitude Scale**. Large earthquakes are not measured very well by the**Richter scale**, especially if the seimometers used are very far away from an earthquake epicenter. The**moment magnitude scale**is now most commonly used for medium to large earthquakes.#### What is the name of the center of an earthquake?

The epicenter is the point on the surface of the Earth directly above the hypocenter of an**earthquake**.

B.

### How the intensity of the earthquake is measured?

Magnitude and

**Intensity measure**different characteristics of**earthquakes**. Magnitude**measures**the energy released at the source of the**earthquake**. Magnitude is determined from**measurements**on seismographs.**Intensity measures**the strength of shaking produced by the**earthquake**at a certain location.#### Can there be a magnitude 10 earthquake?

No**magnitude 10 earthquake**has ever been observed. The most powerful**quake**ever recorded was a**magnitude**9.5 temblor in Chile in 1960. A**magnitude 10 quake would**likely cause ground motions for up to an hour, with tsunami hitting while the shaking was still going on, according to the research.#### What are P waves in an earthquake?

A seismologist is a scientist who studies**earthquakes**and seismic**waves**. Traveling through the interior of the earth, body**waves**arrive before the surface**waves**emitted by an**earthquake**. These**waves**are of a higher frequency than surface**waves**.**P Waves**. The first kind of body**wave**is the**P wave**or primary**wave**.#### What is the first instrument to ever record an earthquake and how did it work?
