Science Alert: Experts Respond

Slow motion quake offers seismic clues – Expert reaction

John Kerr posted in on May 6th, 2016.

For the first time, scientists have watched a slow-motion earthquake unfold below the sea, offering insights into the earthquake and tsunami risk New Zealand faces. A new study, published in the leading journal Science, reports on the Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS) experiment. Two dozen sensors deployed along the seafloor […]

Is a megathrust quake around the corner? – Campbell Live

Laura Goodall posted in on May 20th, 2015.

Campbell Live’s Tristram Clayton and Whena Owen interviewed GNS scientists last night about the latest findings on central New Zealand’s ‘megathrust’ quake zone. We already know that New Zealand is earthquake-prone and that the Hikurangi Margin, where the Australian Plate pushes down on the Pacific Plate, is a hotspot. However scientists have now found evidence, after analysing sediment cores from […]

Evidence of subduction quakes under central NZ – Expert reaction

John Kerr posted in on May 19th, 2015.

Scientists have found, for the first time, direct geological evidence of ‘megathrust‘ subduction quakes occurring under central New Zealand. Subduction earthquakes occur where tectonic plates meet, have the potential to be larger in magnitude than fault ruptures closer to the surface, and are more likely to trigger tsunamis. Analysing sediment cores extracted from a coastal […]
