Frost was in Hong Kong doing business with Nhadra Udaya "A561984". It is possible that that is a result of his presence there with the construction of another NLAP-style project.
When plotting a line from the San Francisco area to the general vicinity of the point where the waves collided, and continuing the line in the same direction for the same distance, Hong Kong is reasonably close
Point of collision is too difficult to ascertain, due to the lack of landmarks, and cloud cover.
The above method may be too simplistic/rely on a flawed projection of the globe, perhaps not using the Great circle method.
The projection from the point of contact need not be the same length, unless the events happened at exactly the same time.
