Seismic loads on cantilever retaining wall

[SSMamar]

Hello fellow engineers,

When designing a cantilever retaining wall, should I add the inertia of the soil over the heel to the driving loads or does the Mononobe-Okabe equation take it into account?

I can't find any reference that answers the question.

Thanx in advance
