Of all the things lake sediments have been used to study – like telling the history of the Spanish climate or showing the unyielding force of California drought – predicting the future likelihood of earthquakes is probably one of the most novel.
Researchers at GNS Science in New Zealand recently put together a research summary for Lake Scientist describing an investigation looking at the probability of quakes near Lakes Mapourika and Paringa that sit along the country’s Alpine Fault. They’ve recently shot a video to further outline the research.
A lot of different equipment was used in the study, including sediment corers, multi-sensor core loggers and modeling software. But as the video illustrates (along with a great explanation of study methods), sometimes bigger tools are needed.
