An earthquake occurs somewhere every day in this world. Earthquakes happen by the powerful movement of rocks in the earth’s crust. It can be also said as the movement of the earth tectonic plates on the earth surface and the earth consists of 20 moving earth plates. When the pressure increase in the moving plates can damage the earth surface and also shaking the earth surface. Earthquakes occur under the sea can cause a tsunami and in the land surface can also cause landslides. The study of all the aspects of earthquakes is known as seismology and it is measured by using seismometers. Similarly, the magnitude of an earthquake is measured by the Richter Scale. Today we are going to see some earthquake facts and its effects
The U.S. Geological Survey predicts that more than 5,00,000 identified earthquake occurs each year in this world and many more are undetectable because of small magnitude and hits in villages. A Survey by the National Earthquake Information Centre found that nearly 50 earthquake happens in a day and 20,000 annually.
- The largest earthquake happened back in chile in 1960 which was recorded as a magnitude of 9.5.
- 80% of earthquakes occur near the Pacific Ocean, Pacific Ocean region is also known as Ring of Fire.
- Next to the Pacific Ocean is Alpide Belt region. In Alpide belt region most of the earthquake happens because where many of earth tectonic plates meet. The Alpide belt region countries are India, Bangladesh, China.
- The seismograph was invented in the year 1880 by John Milne. Richter scale was invented by Charles Richter.
- The number of earthquakes happens in the northern hemisphere more than the southern hemisphere.
- A Research found that 18 major earthquakes and one big earthquake happen every year since 1990.
- If an earthquake occurs in the moon it is called as moonquakes which are not more powerful than earthquakes.
- First earthquake detector was invented by Chinese astronomer Zhang Heng. It can detect up to 600km area.
- The energy of an earthquake is 1000 times powerful than the nuclear or atomic bomb. Also, it is releasing more energy than the atomic bomb dropped on Hiroshima in 1945.
- Before an earthquake occurs a strange smell will come from the canals and ponds due to the release of underground gases. The temperature of groundwater also increases.
- Tsunami waves speed up to 500 miles to 980 miles in an hour. Similarly, seismic waves are 250 miles to 360miles speed in an hour.
- Even earthquake can turn water into gold.
- Namazu is a giant catfish that causes earthquakes in Japanese mythology. similarly, In Greek mythology Poseidon causes earthquakes.
- A survey says that every single minute world has two earthquakes.
- A research found that every year at least one earthquake having a magnitude of 8.0.
- The most earthquake-vulnerable nation in the world is Japan.
- The second largest earthquake occurred in Alaska which was recorded as a magnitude of 9.2. Alaska is the one of the major earthquake occurring state in this world nearly having an average magnitude of 7.2 in a year.
- In 2004 Earthquake in the Indian Ocean took place for nearly 10 minutes which was the highest earthquake recorded in the history ever.
- Earthquake in the Indian Ocean in 2004 which causes a serious tsunami in 14 countries. Tsunami waves were 100 feet tall and hit in coastlines that kills more than 2,85,00 people. It alters the earth rotation up to 2.3cm.
- Earthquakes frequently occur in Japan, Every year 1500 people suffer from earthquakes in Japan.
- Each year in south California nearly 10,000 earthquake occurs which is most by any other countries.
- In China on 1556 around 8,30,000 died by the earthquake which was recorded as world’s deadliest earthquake.
- Back in 1811 near Mississippi, an earthquake occurred under the river which makes the flow of water in backward.
- In 2011 earthquake in Japan, it increases the earth speed by 1.8 microseconds.
- In 1970, A 1000 meter of ice and rock fell down from the mountain Huascaran which is located in Peru. Rocks fell down at the speed of 250 miles per hour that kills nearly 18,000 people.
- Largest landslides happened back in 1920 in China near Kansu province. This incident kills more than 200,000 people.
- Similarly, the largest tsunami occurred in 1771 in Japan which is 275 feet high.
Some valuable tips about what to do when an earthquake occurs:
- If an earthquake occurs in your home or workplace means, firstly duck under the table and cover by your self using any strong material.
- Secondly, Don’t use the elevator if an earthquake occurs indoor. Use only stairs for coming out from home.
- After the shaking of ground stops, Check yourself and person around you then try to move from the building.
- If an earthquake occurs outdoor stay away from the walls, buildings, trees, lamps, electric cables, wooden materials etc…
- Stay away from the glass and don’t use candles flames.
- When earthquakes occur immediately switch off the gases and power off the main switch.
Effects of earthquakes:
- Ground shaking is one of the major effects which damages a lot of building and also kills many people.
- Ground rupture is one of the important effects that damage the earth surface. It breaks the land surface into various parts.
- Both ground rupture and ground shaking caused the Landslides. landslides can block the roads, railway track etc…
- If a magnitude of an earthquake crosses the 7.8 Richter scale means Tsunami will occur. It will damage the coastal line areas.
- Fire accidents are another major effect caused by earthquakes. The volcanic eruption also occurs by earthquakes.
We can’t control the mother nature. Natural disasters are uncontrollable but we can be prepared. We know it is going to come and haunt us one day. But the fact is how prepared are we. Protecting the environment can reduce the effect of natural disaster in some cases. For example, in this modern era, we are living in concrete jungles around us. In most cases, the buildings have been built in areas occupying ponds and lakes. So naturally, when a flood occurs due to excessive rainfall, the water will flow directly to the steep places. We can’t blame nature in the case of human error. Protecting the environment should be a major concern because climate change is one of the key factors in many natural disaster cases. We will constantly update more facts about earthquakes and its effect.
