On October 17, 1989, at 5:04:15 p.m. (P.d.t.), a magnitude 6.9 (moment magnitude; surface-wave magnitude, 7.1) earthquake severely shook the San Francisco and Monterey Bay regions. The epicenter was located at 37.04° N. latitude, 121.88° W. longitude near Loma Prieta peak in the Santa Cruz Mountains, approximately 14 km (9 mi) northeast of Santa Cruz and 96 km (60 mi) south-southeast of San Francisco. The earthquake occurred when the crustal rocks comprising the Pacific and North American Plates abruptly slipped as much as 2 meters (7 ft) along their common boundary-the San Andreas fault system. The rupture initiated at a depth of 18 km (11 mi) and extended 35 km (22 mi) along the fault, but it did not break the surface of the Earth .
James O. Berkland is a Glen Ellen, California-based geologist and editor of Syzygy—An Earthquake Newsletter. He believes the gravitational tugs of the moon, sun, and other planets can influence earthquake activity. Berkland said he has accurately predicted tremors based on factors such as syzygy. "Syzygy" refers to the alignment of three celestial objects. Syzygy of the sun, Earth, and moon occur twice a month, at the full and new moons. At such times, gravitational forces are at a maximum, especially when the bodies are close together, Berkland said.

It's clear to me its most definately erosion and has'nt had regular checks and maintinance.

Im no geologist and dont wish to rip into the OP about the significance of that piece of road falling, but......
would I be alone in thinking that it looks perfectly natural? the sea is in very close proximity to the road and erosion happens naturally so is it not the case that the road just fell due to erosion of the cliff below?
Like I say, im no geologist, just how it looks to me
