This hybrid Swiss Talk brings together experts from Japan, Switzerland, and Italy to discuss how engineering and architectural practice can strengthen the resilience of built heritage in earthquake prone regions. Through case studies ranging from historic temples to urban heritage sites, the event explores how seismic risk mitigation, innovative technologies, and sustainable design strategies can be integrated into conservation practices while respecting cultural and historical values.

In Italy, the safety of built heritage in relation to seismic damage has been studied extensively over the past fifty years, supported by a strong awareness of the historical and cultural significance of architectural assets. The recurrence of earthquakes has led to the development of a well defined regulatory framework and effective procedures for seismic assessment and risk reduction.

Switzerland, characterised by low to moderate seismicity, faces a different challenge. Because damaging earthquakes are relatively infrequent, seismic risk is often underestimated and traditional construction practices, particularly in heritage masonry buildings, usually lack earthquake resistant features. The Swiss approach, based on experimental research, advanced numerical simulations, and the national code for the assessment of existing structures, follows the principle of proportionality, calibrating interventions according to individual and collective risk while balancing safety and economic feasibility.

The comparison with Japan adds a further perspective from a highly seismic context, where advanced technologies and long standing building traditions offer important insights into the conservation of historical structures. By bringing together these three contexts, the event highlights both shared challenges and context specific strategies, making the exchange between Japan, Italy, and Switzerland particularly original and timely.
