“…Research into citizen‐to‐authorities communication, that is, communication for integrating citizen‐generated content in disaster management, has highlighted the immense potential of crowdsourcing, such as the PetaJakarta project, which is mapping Twitter data for flood mitigation (Holderness & Turpin, ), but also issues of disaster managers' mistrust of user‐generated social media data (Mehta, Bruns, & Newton, ). Other studies in this area have conceptualized the use of citizens' activities on social media as “social sensors.” By monitoring the activity of eyewitnesses on social media and mobile phones traffic, an intensification can indicate that a disaster has occurred, thus enabling the fast detection of disasters such as earthquakes (Bossu et al, ). Further research, for example, into the behaviour of social media users during and after the Great East Japan Earthquake of 2011, has revealed not only the importance of multi‐level functionalities, that is, citizen‐to‐citizen, authority‐to‐citizen, citizen‐to‐authority communication, but also the value of linking these different levels of communication (Jung & Moro, ).…”

This study investigates how citizens perceive the role of mobile phone apps specifically designed for disaster communication, and how these perceptions may differ from perceived roles and functions of social media in disaster-related tasks/situations. Focusing on trust in authorities and technology use, results suggest that social media use not only fosters trust via shared narratives and collective sense-making but may also improve trust relationships through local authorities assuming the function of a trustworthy information provider. In disaster apps usage, trust between citizens and authorities is generated through perceptions of shared responsibility rather than shared narratives. Apps were seen as mechanisms that reveal authorities' general willingness to share control, which may help overcome citizens' perceptions that they are distrusted by authorities.

“…For around a decade now, earthquake scientists have begun to use information extracted from social media, websites, or app earthquake reporting, to automatically detect and locate earthquakes within tens of seconds of their occurrence time (Bossu et al, 2008(Bossu et al, , 2018Earle et al, 2010;Steed et al, 2019). Here, rather than relying on such a quantitative survey based on large-scale keywords or hashtags statistics, or website traffic analysis combined with geolocalisation, we build our study on the contextual analysis of qualitative content of selected Twitter conversational threads.…”

<p>Twitter is an established social media platform valued by scholars as an open way to disseminate scientific information and to publicly discuss research results. Scientific discussions on Twitter are widely viewed by the media who can then pass on information to the public. Here, we take the example of two 2018 earthquake-related events which were widely commented on Twitter by geoscientists: the Palu Mw7.5 earthquake and tsunami in the Indonesian island of Sulawesi and the long-duration (more than one year) seismo-volcanic crisis Mayotte island in the Comoros archipelago between Africa and Madagascar. We build our analysis on a content and contextual analysis of selected Twitter threads about the geophysical characteristics of these events. Most authors of this paper have participated to these Twitter threads and related discussions, and regularly explain geohazard events via this social media. From the two selected examples, we show that Twitter promotes very rapid building of knowledge &#8211; in the minutes to hours and days following an event &#8211; via an efficient exchange of information and active discussion between the scientists themselves and with the public. Combining these results with our own experience of communicating geohazard science via Twitter, we discuss the advantages and potential pitfalls of this relatively novel way to make scientific information accessible to scholarly peers and to lay people. We argue that scientific discussion on Twitter breaks down the traditional &#8220;ivory towers&#8221; of academia. It participates to the growing trends towards open science, making science accessible to any non-academics or citizen scientists who can follow and participate in the discussion. This may help people to understand how science is developed, and, in the case of natural/environmental hazards, to better understand their risks.</p>

“…[8] also aims to build a global smartphone early warning system, but it lacks the capability of MyShake to separate earthquake signals from other human activities. There is also an app that detects earthquakes by monitoring when users launch the app and collecting users' reports [3], but it is much slower in terms of detection due to the added human reaction time. Our own prior MyShake publications were in the seismology domain and focused mostly on the functionalities and applications in geophysics.…”

Earthquake Early Warning (EEW) systems can effectively reduce fatalities, injuries, and damages caused by earthquakes. Current EEW systems are mostly based on traditional seismic and geodetic networks, and exist only in a few countries due to the high cost of installing and maintaining such systems. The MyShake system takes a different approach and turns people's smartphones into portable seismic sensors to detect earthquake-like motions. However, to issue EEW messages with high accuracy and low latency in the real world, we need to address a number of challenges related to mobile computing. In this paper, we first summarize our experience building and deploying the MyShake system, then focus on two key challenges for smartphone-based EEW (sensing heterogeneity and user/system dynamics) and some preliminary exploration. We also discuss other challenges and new research directions associated with smartphone-based seismic network.
