We Bet You Didn’t Know This! Five Interesting Facts about Earthquakes
Earthquake is the underground tremors and fluctuations of the earth’s surface, resulting from sudden displacements and ruptures in the earth’s crust or upper mantle and transmitted over long distances in the form of elastic oscillations. The point in the Earth’s crust from which seismic waves travel is called the hypocenter.
The location on the earth’s surface above the earthquake’s hypocenter for the shortest distance is called the epicenter. Earthquakes have been scaring people since prehistoric times. Even more so than volcanoes, because you never know where or when an earthquake might happen.
Besides the damage they can cause, there are many other equally interesting things we can learn about earthquakes. There are lots of interesting facts about earthquakes that people might not know!
For example, not all earthquakes are bad. In fact, did you know that earthquakes make the ground rise higher? By loosening and churning the soil, allowing nutrients and minerals to be transferred evenly, these actions lead to a very fertile type of soil. Earthquakes happen to help plants thrive. Earthquakes also allow scientists to learn more about the structure of the Earth by observing the behavior of seismic waves.
One common method of searching for oil is to blow up certain places before studying the results of seismic activity. Also, not all earthquakes are deadly. In fact, there are millions of earthquakes every year, and most of them are too weak to be registered. Only 100 of the total number of earthquakes occurring each year are capable of causing real damage and casualties. Learn more about this amazing geophysical phenomenon in our list of five interesting facts about earthquakes.
Top-5 Interesting Facts about Earthquakes
Fact 1 Earthquakes
The country with the largest number of earthquakes is the Philippine Republic, but Japan, Indonesia, and Chile are not far behind. And the least frequent underground shocks are recorded in Northern Europe and in the northern part of North America ֵ–ֵ seismic activity there is almost zero. Australia and southwest Africa are also almost never shaken.
Fact 2 Earthquakes
An interesting fact about earthquakes is that in them, the shockwave travels underground at speeds sometimes greater than 25 miles per second. Aftershocks also pose an enormous danger — earthquakes are rarely limited to a single shock, and the first shock is often followed by more aftershocks. And aftershocks are sometimes even more powerful than the first shock.
Fact 3 Earthquakes
The first earthquake in terms of the number of victims is the Great Chinese earthquake. It occurred in Shaanxi province in 1556. The tremors were so strong that they were given a magnitude 8 on a 12 point Richter scale. Nearly one million people were victims of this terrifying earthquake.
Fact 4 Earthquakes
Similar phenomena occur not only on Earth, but also on other geologically active celestial bodies. For example, on Venus or Io, one of Jupiter’s largest satellites.
Fact 5 Earthquakes
The Pacific Ring of Fire, which contains more than half of all active volcanoes on our planet, is the most seismically active part of the planet. Every year, 80-90% of all earthquakes occur there.
