| Popis: | Aotearoa-New Zealand islands sit in the South-West Pacific region where tectonic activity generates one of the world largest seismicity, intense deformation, and volcanic activity. Since 2001, GNS Science Te Pū Ao ensures some of the New-Zealand capability to identify, study, prepare and respond to multiple and frequent geological hazard with the GeoNet programme. GeoNet builds and operates a permanent seismological network routinely maintained and upgraded to provide continuous observations for national and regional events, strong motion and building monitoring. Sensors are distributed over the country with regards to population and hazards exposures. GeoNet strives to optimize its network capability and improve its multi-purposes nature. Around 500 near-real time seismic sensors are acquired, archived, and processed into different products over timelines that match a variety of users and requirements. A range of both rapid and curated products are made available for public awareness, scientists and for earthquakes, landslides, tsunami, and volcanic panels and duty officers. We present the current New-Zealand seismological network, flow process and observation settings as it is, today, a mature observation system. We describe a range of derived seismic products and services designed to enable rapid, dynamic, robust, and resilient scientific seismic information to diverse communities with an open data approach from field instrumentation to data archiving. We discuss expectations and incoming challenges to handle technical and scientific transformations with a care for continuous integration process and maintenance required to evolving monitoring, response, and seismology scopes along with modern 24/7 operations center infrastructure strict design and functions.
