In plain English

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

The largest earthquake recorded near it was M 7.3 in 1892 (The 1892 Laguna Salada, Baja California Earthquake, Mexico) — about 2,800,000 times the energy of an M3.0, the size people start to feel. It released about 1.3 megatons of TNT.
