    <subfield code="a">&lt;p&gt;The critical infrastructure resilience depends on several factors that go beyond the physical&lt;br&gt;
reliability and capacity to repair the system after a disruption. The overall critical infrastructure&lt;br&gt;
resilience includes aspects related to the social and economic backbone governing its capacity to&lt;br&gt;
deliver its service. This contribution presents a theoretical toolkit to calculate the overall resilience&lt;br&gt;
of critical infrastructures developed within the European project LIQUEFACT for earthquakeinduced&lt;br&gt;
soil liquefaction disasters. The toolkit combine several aspects organized in three&lt;br&gt;
dimensions: organizational and management, the physical or technical system and operational&lt;br&gt;
capacity to deliver the service. The toolkit clearly defines also resilience aspects, such as&lt;br&gt;
preparedness, absorption, recovery and adaptation. For each dimension and aspect of the resilience&lt;br&gt;
several indicators are developed. A critical and technical explanation of each indicator is here&lt;br&gt;
proposed, as well a systematic methodology to combine them in the resilience toolkit. The novelty&lt;br&gt;
of this study is the systematic analysis of dimensions, aspects and indicators that made the proposed&lt;br&gt;
resilience toolkit original. The study is concluded with analyses of feasibility of the toolkit to natural&lt;br&gt;
disasters and applicability to localized disasters, such as earthquake-induced soil liquefaction&lt;br&gt;
events. Finally, the key factors of toolkit influencing a built asset model of critical infrastructures are&lt;br&gt;
