• Transpower pylons may be down impacting on the power supply to the North Island. • It is possible that Woodbourne Airport and Omaka Aerodrome will still be useable. • Huge structural damage to residences and businesses – the Seddon earthquakes suggest that wineries are particularly vulnerable with their storage tanks. Economic: • Given the Canterbury economy (as GDP) took two years to recover and many industries have not or took much longer (eg; tourism) a similar situation would occur in Marlborough. Environmental: • In an Alpine Fault rupture slips and slumping are expected to be a major problem. • Liquefaction is expected east of Blenheim. • Landslides could be widespread and rivers may be dammed. • A large earthquake offshore may trigger a tsunami. How do we The risk and hazard are now better understood than ever before; however there is a manage this risk? lack of understanding of what the aftermath of a large Alpine Fault rupture would look like. A joint venture called Project AF8 has been funded by MCDEM over two years from 2016 to 2018. The project brings science and emergency management together to identify the consequences of a large Alpine Fault earthquake for all CDEM Groups in the South island and identify coordinated initial response actions for CDEM Groups. Earthquake monitoring in New Zealand is undertaken by GNS Science’s GeoNet Project which provides a broad-based, around-the-clock monitoring system and a modern data management centre. The monitoring is carried out to provide warnings of any future seismic activity so that appropriate steps can be taken to reduce the risk to lives and property. Council has identified zones at risk of liquefaction caused by earthquakes and is managing development within those areas. Council also has an active programme which focus’ on buildings of two or more stories and pre-1977. Those deemed earthquake prone (“EQP”) have been identified and number 24 properties. Owners have been issued verification notices to strengthen or demolish the buildings however in April 2016 18 buildings are still to complete the notice period. What more • The Lifelines Group could carry out a comprehensive Vulnerability Assessment of should we be the significant assets within Marlborough. doing? • Critical lifelines infrastructure needs to be resilient enough to cope or quickly recover from such severe events. • A comprehensive evaluation of building stock is to be implemented consequent to the Building (earthquake prone buildings) Amendment Act 2016. An implementation statutory start date of 2018 has been set. • The Seddon earthquakes indicated that older residential buildings in particular could benefit from relatively minor strengthening.
