The seismic forces involved in an earthquake and the effects they can have on deep foundations

How "seismic waves" work and what makes some of them hyper-destructive while others create minimal effects

What "soil liquefaction" is, how it works, and why it can create enormous amounts of destruction during an earthquake

Failure modes of deep foundation piles when subjected to soil liquefaction

Helical pier performance during seismic activity and soil liquefaction - from both an experimental perspective and real-world evidence
