Gippsland registers nine earthquakes in six days
By Danielle Pope and Lily Kristanto
A series of earthquakes have hit Victoria's east in the past week. Experts say it is an example of normal aftershock behaviour.

GEO3BCN: New method turns urban and industrial noise into a tool for monitoring the subsurface. “Researchers from Geosciences Barcelona (GEO3BCN), part of the Spanish National Research Council (CSIC), has developed a pioneering method that uses noise generated by human activity to monitor the subsurface continuously and non-invasively. The technique, called REFTION, was tested with data from a […]

🏔️ How can the same earthquake reshape neighboring mountain landscapes in very different ways? The answer may lie in the topography.
New research [link above]… examines how mountain landscapes responded to the great A.D. 1717 Alpine Fault earthquake in New Zealand, revealing that factors including slope steepness, hillslope-to-channel connectivity, and sediment transport capacity can strongly influence the depth and style of post-earthquake erosion.
Researchers compared sediment records from Lake Mapourika and Lake Paringa, two nearby catchments with similar climate, vegetation, geology, and tectonic setting. Using carbon and nitrogen isotopes, molecular biomarkers, and geomorphic analyses, they reconstructed where eroded material came from and how those sources changed following the earthquake.
Despite their similarities, the landscapes responded very differently. In the steeper Mapourika catchment, deep erosion and bedrock landsliding already dominated before the earthquake, so the event dramatically increased sediment delivery without fundamentally changing the style of erosion. At Paringa, however, erosion shifted from predominantly shallow surface soils toward deeper material following the earthquake.
The findings show that pre-existing topography helps determine whether a major earthquake primarily strips away shallow soils or mobilizes deeper soil and bedrock - with implications for sediment transport, landscape evolution, and the movement of organic carbon through tectonically active mountain systems…”
