Is that normal to have an Earthquake at that depth?

Is that normal to have an Earthquake at that depth?

yes its quite common in the pacific.
An example from a quake in july of
this year in the Fiji area is explained
by earthquake report.

How much of the shaking at that depth translates to the surface?

How much of the shaking at that depth translates to the surface?

Probably just a weak shaking according to earthquake report.
Because of the unpopulated area it would be hard to get any
info on actual effects on the surface.

There is NO risk for a tsunami

Thanks answering and for the information. It's crazy to think about things 300-500 miles below your feet.
