Damage and Shaking. Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth's surface caused by seismic waves. The term seismograph usually refers to the combined seismometer and recording device. Earthquakes are a natural phenomenon that occurs when there is a sudden release of energy in the Earth’s crust, resulting in the shaking or trembling of the ground. These events are caused by the movement of the Earth’s tectonic plates and are a common geological occurrence. Read here to learn more. Earthquakes and volcanoes are examples of ...Both the Richter Scale and the Moment Magnitude Scale measure the amount of energy released by an earthquake. On the other hand, the Mercalli Intensity Scale classfies earthquakes by the amount of damage inflicted. It quantifies a quake’s effects on the land’s surface, people, and structures involved. Italian volcanologist Giuseppe Mercalli ...This means that an earthquake of 6 is ten times more powerful than one with a score of 5 and an earthquake of 7 is 100 times more powerful than an earthquake measuring 5 on the Richter Scale. The magnitude (size) of an earthquake is measured using a seismometer. This is a machine that measures movements in the earth’s surface.Major League Soccer introduced a temporary measure last week prohibiting fans attending matches from bringing signs, banners, flags or Tifos that reference the ongoing conflict in the Middle East.Check your chimney or roof for loose tiles and bricks that could fall in an earthquake.
