Earthquake in Japan and Ecuador involves

Every year there are millions of earthquakes but most are small or very small. However, three recent earthquakes in Japan and Ecuador have made the world pay attention because of the tremendous devastation.

Here are 5 things to know about successive earthquakes in Japan and Ecuador:

Are earthquakes in Ecuador and Japan relevant?

According to Paul Caruso, a geophysicist from the US Geological Survey, it is too early to draw a conclusion."Earthquakes in Japan and Ecuador have only happened for a few days so no real research has been done to find out if they are related to each other," Caruso said.

"Normally, we do not think that trans-ocean earthquakes are related to each other," he added, but there are ongoing studies of the possibility that super-powerful earthquakes could be sources. bout for other earthquakes at a great distance.

The distance between Japan and Ecuador is 15,445km (equivalent to 9,590 miles).

The 7.8-magnitude earthquake caused hundreds of casualties in Ecuador on April 16.

What is a fire belt?

All three of these earthquakes occur in the horseshoe-shaped area that the National Geological Society defines as "a circle of volcanoes and areas with many seismic activity, or earthquakes, pulses." around the Pacific belt ".

Therefore, it is possible that earthquakes these few days apart do not happen randomly. But there is another fact that most earthquakes in the world, about 90%, happen in the "ring of fire".

Compare intensity of Ecuador and Japan earthquakes

The earthquake in Ecuador is nearly 16 times stronger than the earthquake on the same day in Japan. While the 7.8-magnitude Ecuadorian earthquake, the same disaster in Japan was 7.0% richter. According to calculations, the magnitude difference is 15,848.

This is the strongest earthquake in Ecuador?

The answer is not. On January 31, 1906, a 8.8-magnitude earthquake struck the coast of Ecuador and Colombia, accompanied by a tsunami that killed about 500 to 1,500 people. Initially, geological organizations said that the earthquake was only 8.2 magnitude.

This is not the strongest earthquake that happened in Ecuador.

On May 14, 1942, a magnitude 7.8 earthquake struck 43km from the epicenter of the disaster. The earthquake on April 16 was the most deadly case since March 1987 when another 7.2 magnitude quake struck the lives of 1,000 people.

How long will it take to get such an earthquake?

According to information collected by the National Geological Society in the past few decades, earthquakes of magnitude 7.0 to 7.9 appear about 15 times a year. Super strong earthquakes, intensity of 8.0 or more, only appears about once a year.
