Street-level imagery (SLI) has become increasingly relevant in crisis informatics; however, its application in post-disaster contexts remains underexplored. Here, we present the systematic capture and public dissemination of over 640 km of SLI following the 2024 Noto Peninsula earthquake in Japan. Combining a survey of 30 participants, interviews with six stakeholders, and an analysis of SLI view metrics, we examine how different populations, including current residents, former residents, and remote observers, perceive its value and risks. While many participants valued SLI as a tool for connection, virtual inspection, and long-term archiving, concerns were raised regarding privacy, vulnerability, and potential burglary. We conceptualize these tensions through the lens of a boundary object, highlighting how disaster-related SLI is not simply a technical artifact, but an emergent sociotechnical infrastructure shaped by ongoing negotiation among contributors, platforms, and affected communities. Furthermore, we address ethical implications related to privacy protection, release timing, and sustainable archiving that can better support infrastructure among stakeholders and affected communities.

While floral tributes are commonly used for the public commemoration of victims of disasters, war, and other accidents, flowers in vases color everyday life. In this research, these features of flowers are intertwined with the recent phenomenon of online memorials to develop a virtual floral tribute concept that includes physical rituals. We designed SenseVase, a smart vase to detect flowers placed in it, and a 3DCG Virtual Memorial that illustrates floral tributes given by people using SenseVases at home. This paper describes how we developed our design concept by reviewing previous literature and social aspects, and presents a video illustrating the concept. To validate the current concept, we interviewed several experts knowledgeable in public commemorations, virtual and online communities, and the floral business. Through a discussion of our findings from the design process and interviews, we propose a new direction for how HCI technology can contribute to public commemoration in addition to personal memorialization.
