North and South Pole of Earth has moved

Each of approximately 200 thousand years, the two poles of the planet earth, north and south of each shift. Generally, the two poles shift takes thousands of years.

Scott Bogue, geologists from Occidental College and Jonathan Glen, researchers from the U.S. Geological Survey (USGS), who observed the lava in the area of Nevada which has 15 million years old.

The result, from the research, they discovered that the planet’s poles have shifted several times faster than normal speed. It happens at least one time.

When the lava cools, it stores records of Earth’s magnetic field. After watching the lava that has cooled for 2 consecutive years, it is known that the lava in the region shifted 53 degrees from the east to the north with a speed of 1 degree every week.
