The Earth faces about 500,000 earthquakes in a year, of which about 100,000 are felt by people.
The 2011 earthquake in Japan was so powerful that it caused a shift in the Earth’s axis, shortened the day’s length by 1.8 microseconds and shifted Japan 2 meters to the East.
The 2004 Indonesian earthquake compressed the earth’s bulge around the equator to some extent and made the earth a bit more round.
Stratovolcanoes are the most dangerous volcanoes on Earth and all the stratovolcanoes are located on the Pacific Rim or the Ring of Fire. This ring is where oceanic and continental plates meet.
In 1970, the tallest mountain of Peru collapsed in an earthquake killing 20,000 people. Two scientists had warned about the same disaster in 1962. However, the government threatened those scientists and banned the civilians to speak about it.
In 1923, an earthquake in Japan caused a fire tornado that burned 38,000 people in just 15 minutes.
The deadliest earthquake known happened in 1556. It hit Shensi province of China and killed about 830,000 people. And the strongest earthquake ever reached a magnitude of 9.5 and hit Chile in 1960.
On September 19, 1985, a massive earthquake of 8.0 magnitude hit Mexico city. In a collapsed hospital, all the newborn babies survived buried under the debris without getting any nourishment. These babies came to be known as “Miracle Babies”.
The Krakatoa volcano in Indonesia when erupted might have been the loudest sound ever made on Earth. Its eruption could be heard even 3000 miles away.

It is said that if a magnitude 15 earthquake strikes, it will destroy the whole planet. However, an earthquake of magnitude higher than 10 is not possible on earth. This is because the magnitude depends on the length of the fault. There is no fault on earth long enough to generate an earth of this high magnitude.
