This earthquake is definitely NOT dangerous as the distance to the populated coast is too far away from the epicenter.

The bottom map shows that only sporadic earthquakes are happening in this area of the world. The bottom map displays the strongest earthquakes since 1900. No reason to fear strong earthquakes here
