Help me to understand better. Is the Seiche induced by a seismic shock? Is it an instrumentally-recorded event?

Salve nel 1695 ci fu un terr che provoco un innalzamento di 4 m del lago bolsena con allag per 3 miglia zona costiera

Quindi? Che altezza si vuole calcolare?

Is there any way to calculate the hight of a seiche wave induced by an earthquake of a known magnitude in a lake of wich you kown the dimensions and depth? We have historical evidence of past eartquake but I wanted a more scientific way to resolve this problem.

I don´t know the details but perhaps this paper could help you: http://link.springer.com/article/10.1007%2Fs11001-010-9103-z

The NTNU or NVE in Trondheim/Norway try to simulate tsunami propagation in fjords for quick clay events. I´ll check in my biblio if I have some more intel on that topic.

Thank's to all for the suggestions on this topic

Rosanna,

I suggest that you compile historical earthquake data and recorded measurements of seiche waves on Lago di Bolsena for those events. Didn't some one note the seiche amplitude for the 1980 earthquake? If not, then perhaps historical photos will show the water line? This may be a question that is easiest to answer with a day or two spent in the library, followed by interviews with residents at the lake.
