Delta subsidence
Radar interferometry and GNSS measure subsidence in deltas, which is added to 海平面上升 to estimate relative change.

Earth and geophysical science explains the coast’s solid ground: sediment supply, subsidence, tectonic movement and submarine hazards. In this field it informs relative sea-level change, coastal erosion 与 海啸 hazard.
Geoscience studies the composition, structure and dynamics of the solid Earth, including earthquakes, volcanoes, landslides and subsurface resources. It informs where and how often geological hazards occur and how they cascade into infrastructure and supply disruption. In oceans and coasts, climate and hazards and biodiversity and nature, geoscience sets ground-shaking and ground-failure inputs for building codes, siting and catastrophe models. It identifies where single geological events can disrupt multiple networks at once. The canonical description is on STEM Commons.
Radar interferometry and GNSS measure subsidence in deltas, which is added to 海平面上升 to estimate relative change.
Sediment supplied by rivers and moved along the coast is estimated to understand erosion and the effect of dams and coastal works.
Subduction zones and submarine landslide areas are characterised with geological and seafloor data to support 海啸 hazard assessment.

Assembled from the Nexus Standards area profile 海洋与海岸风险标准: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

示例地理范围
Hazard models are tested against historical and paleoseismic catalogues and observed ground motions. Deformation estimates are cross-checked between independent geodetic techniques.

| GNSS comparison | Radar subsidence rates are compared with GNSS |
| Budget uncertainty | Sediment budgets state their uncertainty |
| Source model review | Tsunami sources are reviewed by geological services |
Catalogues are short relative to recurrence intervals of large events. Fault interactions and triggering are difficult to predict deterministically.
