Earthquake hits Guanajuato State

[jesm]

The recent shaker caused me to look for other seismic events impacting GTO.
In April, 1845 a huge earthquake rattled much of central Mexico causing widespread damages. A lack of population, little news media and accurate seismic measurement devices kept this event largely unreported to the outside world.
Using modern methodology today’s seismologists rate this 1845 quake at a minimum 8 on the Richter scale. That equals the hugely damaging 1985 Mex City event that killed 5,000 people and damaged thousands of structures.
Detailed reports of exact damages here do not exist, but Guanajuato Capital was cited as having been impacted in Mexico City newspapers describing the 1845 event.
