grant 40 Posted April 12, 2014 Author Share Posted April 12, 2014 National Advisory: Tsunami - Potential threat to New Zealand Cancellation Strong and unpredicable currents may still occur ________________________________________ No: 02 ________________________________________ Issued at 0950 hours on 13.04.14 Issued by the Ministry of Civil Defence & Emergency Management (MCDEM). Tsunami advisory cancelled: The tsunami experts panel (TEP) has convened and they are advising that there is not likely to be a tsunami threat for New Zealand. This is based on the revised magnitude (Mw 7.6), and depth of the earthquake. Some caution will still have to be given regarding potentially strong, unpredictable currents around coastal areas of New Zealand. This includes areas around the northwest part of the North Island, and based on past experience along the west coast of the South Island (e.g. Greymouth, Westport). Travel times to the northern end of the North Island are approximately 4 hours, and to the west coast of the South Island approximately 6 hours. We strongly advise caution over the next 24-48 hours. ________________________________________ Earthquake parameters: Origin time: 2015Z 12 April 2014 NZ time: 2015 NZST 13 April 2014 Co-ordinates: 11.3 S 162.3E Depth: 33km Location: Solomon Islands Magnitude: 7.6 (was revised down from 8.3) The above magnitude is provisional and may be increased or decreased as more seismic data becomes available. ________________________________________ Summary: This is the last message via the national warning system for this event, unless significant further information is received. This cancellation message has been issued to all local civil defence authorities, emergency services, other agencies and media. This cancellation message will be broadcast under the Memorandum of Understanding (MoU) with public broadcasters. ________________________________________ NCMC status: The National Crisis Management Centre (NCMC) is standing down from 1030 hours.

eruptn 95 Posted April 12, 2014 Share Posted April 12, 2014 The correct time is 2015Z ... thats UTC Universal Time or Greenwich etc (12 hours out with us). Some one in MCDEM got the conversion to local wrong it appears. #SolomonsTsunami Advisory-2 The Tsunami Expert Panel has advised the Ministry that with the Solomons earthquake downgraded to 7.6 there is now no tsunami threat to New Zealand. However, people should expect stronger and unusual currents on the coast, especially in harbours or estuaries. People in boats or at the beach, should be particularly careful. The stronger and unusual currents are likely to last all day. Looks like more unusual currents an tides this afternoon/evening. Travel time is about 4-6 hours from the Solomons. May be an interesting afternoon getting back in a berth. Link to post Share on other sites
