🧵🇬🇧1/10 #OTD 30 years ago, the 1992 M5.8 #Roermond earthquake shook the Netherlands, exactly one month before this earthquake geologist was born on the opposite side of the Roer Valley Graben.

A thread on why the first of these two shocks is so interesting: The Roermond eq occurred along the Peel Boundary Fault Zone in SE Netherlands. The fault zone is part of the Lower Rhine Graben, a NW-SE striking normal fault system in intraplate Europe. The eq in 1992 served as a reminder that the Netherlands is naturally seismically active.

60 years later, this famous offset ridge looks almost exactly the same as it did immediately post-earthquake:
