A geological hazard or geohazard is an adverse geological condition capable of causing widespread damage or loss of property and life. In Northern Ireland a range of geohazards are known to cause disruption and damage to existing infrastructure. When planning new or upgrading current infrastructure, it is essential that the potential for geohazards, be they natural or anthropogenic, be explored. Once identified geohazards can be either eliminated or mitigated. Northern Ireland’s geological complexity determines the range and distribution of geohazards encountered. In addition to this geological complexity, climate change is bringing, for example, more adverse weather conditions and a rising sea level, which can only exacerbate geohazards. The first half of this event will feature Prof.
Mark Cooper (GSNI chief geologist of Northern Ireland) who will give an overview of the bedrock and superficial geology of Northern Ireland. He will then describe a range of landslips, their drivers, and impacts on infrastructure.
Mr Kieran Park (senior geohazards geologist) will then discuss the broader spectrum of geohazards that manifest in Northern Ireland. In addition to landslips, these can include subsidence due to natural and man-made voids (cave and mines), compressible ground (sleech and peat), and flooding and coastal change. He will then describe the range of GSNI datasets and products than can help to identify geohazards. Examples will include the recently published Belfast Engineering map, Peat Slide Risk Assessment, and Developing in Areas of Abandoned Mines guidance.
GSNI would like to take this opportunity to hear back from ICE/GSL members on the geohazard challenges they encounter, and what datasets or products they would like to see produced to aid identification, prediction and mitigation. To achieve this a short questionnaire will be shared at the end of the event.
