Riassunto

This is an open access book. Probabilistic tsunami hazard and risk assessment (abbreviated as PTHA and PTRA, respectively) has evolved quickly over the past 10 to 15 years and now forms the basis of many risk mitigation efforts. Methods are largely based on those used for probabilistic hazard and risk assessment for earthquakes. However, while seismic risk can be represented by a single workflow, tsunami risk is characterized by a number of different and cascading workflows. Funded in parts by the COST Action CA18109 AGITHAR (2019-2023), a group of more than 120 experts gathered to advance the scientific basis for PTHA and PTRA. Amongst them were over 50 volunteering to contribute to this so-called “cookbook” for PTHA and PTRA.

The aim of our cookbook is to give an overview of existing methods for PTHA and PTRA, to unify the description of named workflows, and to make best practices examples available to a wider community. We use the analogy of a cookbook, because we strive to describe the ingredients, i.e., the basic building blocks of PTHA and PTRA, and give examples of good recipes, i.e., well-designed workflows for concrete application fields. Furthermore, a cookbook gives inspiration but does not necessarily standardize methods. So, while this effort aims at some standardization of methodology, it gives enough freedom to build on this knowledge to further develop the field. The book is intended for scientists, but also practitioners and decision-makers in tsunami hazard and risk mitigation.

This is an open access book.

 

Cost Action CA18109 AGITHAR intends to forward the scientific basis for probabilistic tsunami hazard and risk analysis (abbreviated as PTHA and PTRA, resp.). A group of more than 120 experts in the field have gathered in this networking initiative, amongst them over 50, volunteering to contribute to the so-called cookbook.

 

While the seismic community has used probabilistic assessment methods for quite some time, this is relatively new for the tsunami community. And while the seismic risk can be represented by a single workflow, the tsunami risk is characterized by a number of different and cascading workflows.

 

There are four major and physically quite different sources of tsunami: i) seismic events (earthquakes); ii) landslides, possibly triggered by earthquakes; iii) volcanic events (flank collapses, eruptions, explosions); iv) meteorological events. A fifth source, meteoroid impact,is usually neglected because the tsunami caused by such events is either negligibly small or is only a secondary hazard if the meteoroid is so large that the tsunami is significant.

 

These four different sources are very distinct in their character and require different modeling, monitoring, and uncertainty quantification methods and result in different workflows. On the other hand, these workflows eventually result in similar statements regarding the hazard and risk of exposed communities.

 

The aim of our cookbook is to give an overview of existing methods, to unify the description of named workflows, to make best practices examples available to a wider community, and to reach out to stakeholder groups. We use the analogy of a cookbook, because we strive to describe the ingredients, i.e., the basic building blocks of PTHA and

PTRA, and give examples of good recipes, i.e., well-designed workflows for concrete application fields. Furthermore, a cookbook gives inspiration, but does not necessarily standardize methods. So, while this effort aims at some standardization of methodology, it gives enough freedom to build on this knowledge to further develop the field.
