I am at an historic site that hosts an annual and popular Civil War
Reenactment.  Recently, there have been questions about the effects of
vibration from cannon fire on the historic structures.  Does anyone know of
research in this area? Has anyone conducted tests or noticed an impact on
structures?  I am fairly new to the list so I apologize if this topic has
been covered recently. Thank you for your responses.
