Question

what do you mean seismologist? discuss focus hypocenter and epicenter. how do we measure it magnitude and intensity answer
​

Answer 1

Answer:

Seismologists are Earth scientists, specialized in geophysics, who study the genesis and the propagation of seismic waves in geological materials. These geological materials can range from a laboratory sample to the Earth as a whole, from its surface to its core.

The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus. See also epicenter.

Reading: Magnitude versus Intensity

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.

Answer 2

Explanation:

Seismologists are Earth scientists, specialized in geophysics, who study the genesis and the propagation of seismic waves in geological materials. ... At the Geological Survey of Canada, the Seismology and Electromagnetism Section carries out such research.Seismology is the scientific study of earthquakes and related phenomena, such as volcanic eruptions. Earthquakes occur when the tectonic plates that make up the Earth's crust shift and release energy in the form of waves.

Earthquakes occur when the tectonic plates that make up the Earth's crust shift and release energy in the form of waves.The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus. See also epicenter.The point inside the crust where the pressure is released is called the focus . The point on the Earth's surface above the focus is called the epicentre . Earthquake energy is released in seismic waves.The epicenter is the point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.
