what is the difference between earthquake intensity?
364989
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.

Originally Answered: What is the difference between intensity and density? ... Density refers to mass concentration, that is, the amount of mass that is contained in a certain volume (or surface, if we are talking about a 2D system). Intensity however refers to power concentration, with time becoming a fundamental factor.

Earthquake vs tremors Earthquakes are the vibrations caused by rocks breaking under stress against an underground surface called a fault plane while a tremor is an involuntary movement of earth surface caused by stress in the underground rocks. They are both signs of seismic movement within the earth.

magnitude. The magnitude is a number that characterizes the relative size of an earthquake. ... The moment magnitude (Mw) scale, based on the concept of seismic moment, is uniformly applicable to all sizes of earthquakes but is more difficult to compute than the other types.

Some factors that affect intensity are the distance away from the epicenter, the depth of the earthquake, the population density of the area affected by the earthquake, the local geology of the are, the type of building construction in the area, and the duration of the shaking.

Soil type is a critical factor, because the density of the ground has a direct effect on the amount of motion the ground will experience during a quake. Hard ground propels the energy quickly with a small amplitude, while soft ground slows the energy down and increases the amplitude of the motion.

Differences between volcanoes and earthquakes Volcanoes form at Earth's surface whereas earthquakes originate from deeper within the crust. ... Volcanoes are formed by release of gas and magma. Earthquakes are caused by movement along a fault.

What is the difference between warning of an earthquake and predicting an earthquake? Earthquake warnings occur immediately after an earthquake begins to help people to escape buildings and avoid injury. ... Earthquake predictions advise people to evacuate an area before an earthquake begins.

Magnitude measures the amount of seismic energy released at the source - or hypocenter - of an earthquake. An earthquake has only one magnitude determined from measurements on seismographs. The first widely-used measurement was the Richter scale.

Distant vs. It is important to understand the difference in both scale of event and response requirements for a local and a distant tsunami event. Local Tsunami - caused by an earthquake in the Cascadia Subduction Zone. Distant Tsunami - caused by an earthquake on a subduction zone elsewhere in the Pacific Ocean.

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. Intensity is determined from effects on people, human structures, and the natural environment.

The earthquake does denote an earth movement that is strong and does significant damage. A tremor is usually a mild earthquake and does no damage. A temblor is usually stronger,felt more and may shake windows and doors. All of above earthquake is more hazardous.

In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests.

Earthquakes and volcanic eruptions are different because (tectonic, i.e. powerful) earthquakes are vibrations travelling through the Earth that are produced by the tectonic plates of the crust slipping past each other, whereas volcanic eruptions are (for the most part) simply molten crust needing to escape at the ...

Question: What is the difference between Magnetic Intensity and Intensity of Magnetisation? Answer: The magnetic intensity defines the forces that the poles of a magnet experiences in a magnetic field whereas the intensity of magnetization explains the change in the magnetic moment of a magnet per unit volume.

Intensity: The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale. Magnitude: Earthquake size is a quantitative measure of the size of the earthquake at its source. The Richter Magnitude Scale measures the amount of seismic energy released by an earthquake.
