An earthquake is a vibration or vibration that occurs on the surface of the earth due to the sudden release of energy from within that creates a seismic wave. Earthquakes are commonly caused by the movement of Earth's crust (Earth's plates). Frequency of a region, referring to the type and size of earthquakes experienced during the time period. Earthquakes are measured using Seismometer tools. Momentmagnitudes are the most common scale in which earthquakes happen for the whole world. The Rickter scale is the scale reported by a national seismological observatory measured on a local magnitude 5 magnitude scale. Both of the same scale over the range of their numbers are valid. Earthquakes of 3 magnitude or more are largely barely visible and its magnitude 7 more potentially cause serious damage in large areas, depending on the depth of the earthquake.

Aceh is a province in the western tip of the country Indonesia, which is the province of the largest Muslim population in Indonesia, so dubbed the name "Serambi Makkah". Most of the population works as farmers. Aceh is located in the western tip of Indonesia is not apart of natural disasters, since the year 2014-2017 recorded aceh already 3 times in the big earthquake that swallowed thousands of lives and the eyes of the world focused on this province. The last tragedy that struck Aceh was the tragedy of the Pidi Jaya Earthquake on a 6.5 rister scale and claimed 104 lives. Then the question is why Aceh is always hit by a big earthquake?

This incident occurred because of the shift of large earthquake after the earthquake in 2004. Because of the position of the earth, the island of Sumatra, the potential is often hit by the earthquake.

Aceh on the island of Sumatra is the most often hit by earthquakes. Sumatera Positioned in one corner of the Asia Pacific Ring of Fire.

The Asia Pacific Ring of Fire is a term for the region in the most active seismic circle in the world.

The most active earthquake trails in the world range from the United States, Canada to New Zealand through thousands of Indonesian islands.
