In plain English

The two sides move 1 to 5 mm a year — 10 to 50 cm (4 to 20 inches) every century.

It has broken the ground surface within the last 150 years.

The largest earthquake recorded near it was M 6.4 in 1933 (The 1933 Long Beach, California Earthquake) — about 130,000 times the energy of an M3.0, the size people start to feel. It released about 60 kilotons of TNT.

USGS maps it as 7 sections: Dana Point section, Del Mar section, Oceanside section, San Diego section, Silver Strand section, north Los Angeles Basin section, south Los Angeles Basin section.
