1. What is an earthquake? The sudden and brief period of intense ground shaking. Where magma is erupted from the earth. The movement of earth's plates creating new land.Credit: Public Domain The location where an earthquake begins is called the epicenter. 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?Typically, about 100 earthquakes greater than M1.5 occur every day, but most of these are less than M4. The bigger the earthquake, the less frequently they occur. Measuring earthquake intensity. The Mercalli scale describes the intensity and features of an earthquake, based on its observed effects.

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 …

It is a qualitative measure of the actual shaking at a location during an earthquake. Normal numbers are used to determine the magnitude of earthquake. Intensity is assigned as Roman Capital Numerals. Credit: Public Domain The location where an earthquake begins is called the epicenter. 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 intensity is a number (written as a Roman numeral) indicating the damage caused by an earthquake. An earthquake has several intensity values, because the shaking and the damages can vary from place to place depending on the distance from the epicenter. The intensity is calculated using human observations and reports of felt shaking and damage.

Chile earthquake of 1960, the largest earthquake recorded in the 20th century. Originating off the coast of southern Chile on May 22, 1960, the temblor caused substantial damage and loss of life in Chile and—as a result of the tsunamis it generated—in Hawaii, Japan, the Philippines, and other distant coastal areas.

Magnitude scales can be used to describe earthquakes so small that they are expressed in negative numbers. The scale also has no upper limit. Aquí nos gustaría mostrarte una descripción, pero el sitio web que estás mirando no lo permite.An earthquake that causes ground motion at a seismic station (when corrected for distance) 10 times larger than the reference earthquake is M2. An earthquake causing motion at that distance 10 times larger than an M2 is an M3, and so on. To achieve this ten fold increase in ground motion requires about 32 to 33 times the energy.Some of them are severe in nature. The most dangerous thing about an earthquake is that it is quite unpredictable. It can cause several damages without any previous indication. The intensity of an earthquake is measured by the Richter’s scale. Generally, earthquakes occur due to the movement of tectonic plates under the earth’s surface.A magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake.
