Can an earthquake shifted the Earth's axis and how many times has the Earth's axis changed?
The changes in Earth's rotation and figure axis caused by earthquakes should not have any impacts on our daily lives. "These changes in Earth's rotation are perfectly natural and happen all the time," he said. "People shouldn't worry about them. Additionally, how much Earth's axis is tilted towards or away from the Sun changes through time, over approximately 41,000 year cycles?
An earthquake cannot change the position of the Earth's axis of rotation. The axis of the Earth cannot change its position. The earth is a gyroscope. But the solid shell can slide over the asthenosphere.
The answer to your question.
The solid shell of our planet slid across the asthenosphere 6 times. For this reason, there could be an erroneous feeling that the Earth's axis of rotation tilted 6 times.
Let us analyze the change in the axis of rotation of the Earth after the strongest earthquakes. https://www.emsc-csem.org/
Attached is a graph of changes in the coordinates of the Earth's rotation axis. https://hpiers.obspm.fr/
This is the strongest earthquake in the solid shell of the Earth:
Magnitude Mw 9.0
NEAR EAST COAST OF HONSHU, JAPAN
Date time 2011-03-11 05:46:23.0 UTC
Location 38.30 N ; 142.50 E
Depth 22 km
This is the strongest earthquake in the liquid shell of the Earth.
Magnitude Mw 8.3
Region SEA OF OKHOTSK
Date time 2013-05-24 05:44:48.0 UTC
Location 54.91 N ; 153.34E
Depth 598 km
