This means that most of the epicentres of these earthquakes are located in southern Spain, specifically in Andalucía, Murcia and Alicante - on land - and in the Gulf of Cadiz and the Alboran Sea - on water. Earthquakes registered according to intensity or magnitude on the Iberian peninsular and surrounding areas.An earthquake’s most intense shaking is often felt near the epicenter. However, the vibrations from an earthquake can still be felt and detected hundreds, or even thousands of miles away from the epicenter. How Do We Measure Earthquakes? The energy from an earthquake travels through Earth in vibrations called seismic waves. Scientists can ...The strength of an earthquake is measured in terms of amplitude and frequency. Amplitude is the height of the wave on the seismograph. Frequency is the number of waves per second.

Also called a temblor, an earthquake is caused by the movement of parts of the Earth’s crust, its outermost layer. They happen millions of times a year, but most are so small people don’t even feel them. But powerful earthquakes can cause landslides, tsunamis, flooding, and other dangerous events.The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction.

For example, an earthquake with a magnitude of 7 is ten times more powerful than an earthquake with a magnitude of 6.An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.Earthquake detection. A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia, that is, where a suspended mass tends to remain still when the ground moves.
