@Ohemaa, the passage gives a range of years that lichenometry is useful, but it never mentions a specific quake that was dated to any particular time. However, lines 56 to the end describe a few elements that need to be factored in to accurately assess the growth - specifically shade and wind are listed as contributing to quicker lichen growth.
