Effective disaster risk reduction requires conducting research within communities that gave recognized natural or technological risks, to foster the development of more resilient societies. However, limited information is available regarding risk perception and preparedness for technological hazards in disaster-prone urban areas of South America. The aim of this study is to investigate the factors that influence public risk perception regarding the Trans-Ecuadorian Oil Pipeline System and its relationship with household preparedness for a potential accident in the Metropolitan District of Quito (Ecuador). We assess the link among knowledge, trust in authorities, risk perception, intention to prepare, and preparedness. Results from a sequential mediation analysis reveal that risk perception partially and positively mediates the relationship between knowledge and preparedness and acts as a negative full mediator between the latter and trust. These findings provide valuable information for future risk governance and communication strategies, aimed at enhancing risk perception and improving individual preparedness of individuals, as well as risk mitigation procedures

En este trabajo se aplica una metodología nueva al estudio de las noches calurosas, también denominadas «tropicales», en Galicia y en Portugal de cara a identificar aquellas noches
en las que la población pueda verse afectada por estrés térmico. La utilización de dos indicadores obtenidos a través de datos semihorarios ha permitido definir con más detalle las características térmicas de las noches entre mayo y octubre, pudiendo así evaluar con más precisión el riesgo para el bienestar y la salud de la población. Se produce un importante aumento de la frecuencia de noches tropicales y noches cálidas en la fachada atlántica, desde el norte de Galicia hasta el sur de Portugal. La menor latitud y la proximidad al litoral están relacionadas con la mayor persistencia del calor y del estrés térmico durante estas noches. En áreas de interior la persistencia es menor. Las noches calurosas son más frecuentes e intensas en el centro de las ciudades, por el efecto de la isla de calor urbana.; This paper presents a new methodology for the study of warm nights, also called «tropical», in Galicia and Portugal in order to identify those nights where people can be affected
by heat stress. The use of two indicators obtained through half-hourly data has allowed us to
define in more detail the thermal characteristics of the nights between May and October, thereby being able to more accurately assess the risk to the health and well-being of the population. There is a significant increase in the frequency of tropical nights and warm nights on the Atlantic coast, from the north of Galicia to the south of Portugal. The lower latitude and proximity to the coastline are associated with greater persistence of heat and thermal stress during these nights. In inland areas the persistence is less. The warmest nights are more frequent and intense in centres of the cities, due to the effect of the urban heat island.
