“…Volcanic ash, gases, and debris dispersed in the atmosphere by explosive eruptions can impact populations living not only in the neighborhood of the volcano but also within several thousand kilometers of the source (Plag et al, 2015). The recognition of the importance of monitoring volcanoes led to the first observation of volcanic activity with seismometers at Vesuvius in 1856 and then to the development of seismic monitoring for the rest of the world.…”

Infrasonic Early Warning System for Explosive Eruptions

Explosive volcanic eruptions can eject large amounts of ash into the atmosphere, posing a serious threat to populations living near the volcano. The abrupt occurrence of such events requires a rapid response and proper volcanic hazard evaluation. Current monitoring procedures still require human intervention, which often results in significant delays between the occurrence of an eruption and notifications being dispatched. We show how dedicated infrasound array processing can be used to detect and notify the authorities, automatically and in real time, of the onset of explosive eruptions. Conceptually, our method relies on the strong coupling between infrasound and the explosive process, and it is not based on probabilistic considerations but on the ability infrasound has to detect the early stage of the explosive phase. This procedure has been tested for the last 8 years, and it is currently applied to issue early warnings for explosive eruptions at Etna Volcano. We show that the system is able to provide a prealert ~1 hr before the eruption, and it has a 96.6% success rate, with only 1.7% false positive alerts and no false negative alerts. This is, to our knowledge, the first example of an operational early warning system totally based on an unsupervised algorithm that provides automatic notifications of eruptions to a government agency. We show that the same early warning concept might be applicable to arrays at large distances (>500 km), suggesting that infrasound could be successfully used to issue automatic notifications of ongoing eruptions at regional to global scales.

“…While both scientists and practitioners rely on science and technologies in addressing the complex issues of integrated Earth systems, a strong in-reach engagement is required in co-producing and using comprehensible geomorphic observations in support of decision-making for a wide range of societal areas (Plag et al, 2013). According to Plag et al, the partners' engagement foci in this area should include: a) improving interoperability between various types of observations, modeling, and information systems; b) facilitating data sharing, archiving, dissemination, and reanalysis; c) optimizing observation datasets, assimilation of data into models, and generation of data products; d) enhancing the value of observations from individual observing systems through their integration; and e) harmonizing well calibrated, highly accurate observations of the same variable recorded by different sensors and different agencies.…”

River morphology data are critical for understanding and studying river processes and for managing rivers for multiple socio-economic uses. While such data have been acquired extensively over time, several issues hinder their use for river morphology studies such as data accessibility, variety of data formats, lack of data models for data storage, and lack of processing tools to assemble the data in products readily usable for research, management, and education. A multi-university research team has prototyped a web-based river morphology information system (RIMORPHIS) for hosting and creating new information and data processing tools to be shared with the broader earth science communities. The RIMORPHIS design principles include: (i) broad access via a publicly and freely available platform-independent system; (ii) flexibility in handling existing and future data types; (iii) user-friendly and interactive interfaces; and (iv) interoperability and scalability to ensure platform sustainability. Development of such an ambitious community resource is only possible by continuously engaging stakeholders from the inception of the project. This paper highlights the research team’s strategy and activities to connect and engage with river morphology data producers and potential users from academia, research, and practice. The paper also details outcomes of stakeholder engagement and illustrates how these interactions are positively shaping RIMORPHIS development.

“…The lexicon (ontology) contained in the Socio-Economic and Environmental Information Needs Knowledge Base (SEE-IN KB) as the primary source for all semantic aspects will grow based on deep learning from other registries and from user interactions. The Socio-Economic and Environmental Information Needs Knowledge Base (SEE-IN KB) provides access to a large set of user needs (originally collected in the Global Earth Observation System of Systems (GEOSS) User Requirements Registry (URR) [68,69]) and observational requirements (partly harvested from OSCAR, see http://www.wmo-sat.info/oscar). The Socio-Economic and Environmental Information Needs Knowledge Base (SEE-IN KB) explores existing and new data repository in an effort to link Earth observations (EOs) and the global community of potential users.…”

“…The experience with the URR shows that users wanted the graphs to be extended to include far more groups, such as models, tools, people, data, knowledge, decision and policy making, etc. [69].

The exploitation of potential societal benefits of Earth observations is hampered by users having to engage in often tedious processes to discover data and extract information and knowledge. A concept is introduced for a transition from the current perception of data as passive objects (DPO) to a new perception of data as active subjects (DAS). This transition would greatly increase data usage and exploitation, and support the extraction of knowledge from data products. Enabling the data subjects to actively reach out to potential users would revolutionize data dissemination and sharing and facilitate collaboration in user communities. The three core elements of the transformative DAS concept are: (1) “intelligent semantic data agents” (ISDAs) that have the capabilities to communicate with their human and digital environment. Each ISDA provides a voice to the data product it represents. It has comprehensive knowledge of the represented product including quality, uncertainties, access conditions, previous uses, user feedbacks, etc., and it can engage in transactions with users. (2) A knowledge base that constructs extensive graphs presenting a comprehensive picture of communities of people, applications, models, tools, and resources and provides tools for the analysis of these graphs. (3) An interaction platform that links the ISDAs to the human environment and facilitates transaction including discovery of products, access to products and derived knowledge, modifications and use of products, and the exchange of feedback on the usage. This platform documents the transactions in a secure way maintaining full provenance.
