Powerful tsunami lifted Tongan boulder up a cliff
It makes the boulder known as Maka Lahi the largest in the world to be moved by a wave.
The University of Queensland PhD candidate Martin Kohler said the finding outlined in their research provides new insight into tsunami history in the area and future risks.
"It's a bit hard to compare tsunamis, but what we can say is that there was no record so far in history of a similar sized wave. So we modelled the wave to move Maka Lahi to be 50m high," said Mr Kohler.

Search on for how and where SA's algal bloom started, and where it's going
As South Australia's algal bloom creeps along the state's coasts, scientists are trying to find out what caused it, where it started and where it is heading next. The current bloom was first reported on beaches on the southern tip of the Fleurieu Peninsula in March before spreading across the Gulf of St Vincent. The federal and state governments have committed a combined $28 million to tackle the issue, some of which will be spent on research. University of Technology Sydney harmful algae bloom expert Professor Shauna Murray said the impact of the bloom was unprecedented in Australia. Professor Murray said while it was important to understand the chain of events that led to the bloom, more important was understanding how it could be quickly detected "so we can be prepared to respond to it", she said. "If it occurs then we know what to expect, we know what areas it might affect, we might understand a bit better how it will affect those areas." Though the first reports linked to the bloom were on Waitpinga Beach, estuarine ecologist Faith Coleman thinks fish kills further south and east could have been connected. "Areas like Portland in Victoria, and looking at the Eight Mile Creek [south of Mount Gambier], those places have had over the last couple of years [seen] a series of smaller blooms, best we can tell," Ms Coleman said. "Although they weren't investigated at the time, each one of those periods of large fish kills have tied into an extreme event relating to a large amount of seagrass death and seaweed death, and either exceptionally cold or hot waters. "We suspect that this particular bloom started somewhere near Robe." While it was not yet clear exactly where the bloom started, Flinders University Associate Professor Jochen Kaempf is trying to predict where it is going. He has developed a computer model to predict how the bloom could be developing. "It very likely becomes weaker and might disappear, or looks like disappearing," Dr Kaempf said. "The big question is whether it will turn up again when it gets warmer in the next summer months. "Will it maybe appear in the Spencer Gulf? [That] is way more concerning in terms of its ecological significance. "We have the sardine stock, the prawns, the cuttlefish. That's a big concern." The state government has said a marine heatwave, nutrients washing into the sea from the 2022-'23 River Murray flood, and an "unprecedented" cold-water upwelling in the summer of 2023-'24 are plausible contributing factors to the bloom. Dr Kaempf discovered the Great Southern Australian Coastal Upwelling System and has been studying it for more than two decades. The event attracts a range of marine life, including dolphins and whales. Dr Kaempf said there would not be a relationship between the 2023-'24 upwelling and the current bloom as blooms develop over the course of one to two months. "It's just too long ago and not linked to the bloom that we're seeing now," he said. Ms Coleman said the impacts of the upwelling on the algal bloom are likely to be insignificant compared to the marine heatwave. "What happened is what always happens — which is that it blows a little bit of extra nutrients that it's accumulated over time up into the main water column," she said. "Those were immediately taken up by a diatom bloom that you could see from space." Ms Coleman said the government likely has not had time to rule out the upwelling or flood as contributing factors. "Even SARDI and PIRSA reports say quite clearly the primary cause is climate change," she said. South Australia's Department for Primary Industries and Regions was contacted for comment.

Queensland mining data informs better understanding of underground stresses
New research into the world's tectonic plate stress patterns has led to a better understanding of how the mining and construction industry affects what goes on beneath the Earth's surface. The latest World Stress Map, released this week, revealed new earthquake trigger data and information about how stress builds in the Earth's crust as a result of underground mining activity mapped in Queensland's Bowen Basin. Mojtaba Rajabi, from University of Queensland's (UQ) School of Environment, said the latest update to the map could help make underground mining and construction activities safer by providing better insights into the Earth's stress conditions. "Digging, drilling or injecting fluids in the wrong spot can tip the underground balance and induce a seismic event. "Understanding stress helps us prevent these man-made shakes." Through UQ's collaboration with Germany's GFZ Helmholtz Centre for Geosciences, the Earth's underground stress patterns have been mapped in more detail than ever before. Dr Rajabi said the latest update included more than 100,000 stress data records. "This is almost double the data from the previous release we published in 2016," he said. The new data from central Queensland's mining heartland, the Bowen Basin, has found a dramatic rotation in underground stress of more than 50 degrees within 100 kilometres. Dr Rajabi said the mining data, which was analysed remotely, would lead to pinpointing vulnerable areas that could potentially trigger earthquakes. "The direction of the tectonic force coming from the plates east of Australia change dramatically, and when these forces interact with local geological conditions they redirect stress in different ways," he said. "As a result, the safest directions for drilling and excavation can vary significantly between locations in the same region. "This gives us a really great guide on ways we can dig safer in terms of mining or reservoir analysis studies, such as in our gas exploration." The Queensland Mining and Energy Union said the new data would be a vital tool for researchers and industries working to ensure the safe use of the Earth's sub-surface. Mining health and safety representative Jason Hill said it had the potential to help coal mines with strata control — a method used to maintain the stability of the ground. "Strata control is a principal hazard and it has killed a lot of people over the years, so any data or research into the management of strata is very much welcome," he said. Mr Hill said he hoped mining operators would adopt the findings. "The most important thing now is the companies actually take a look at [the report] and use it to ensure that they are achieving an acceptable level of risk," he said. The World Stress Map has been updated every decade for more than 40 years, drawing on data from seismology centres, the energy and resources sector and civil engineering projects across the globe. Dr Rajabi said Australia's underground stress patterns were unlike any other continent. "Highly variable, full of twists and turns, and not aligned with the direction the continent is moving," he said. "With this [new] level of detail, we can now better understand how tectonic forces behave not just across regions but at the local scale too."

Scientists release seven-point plan to tackle SA's 'catastrophic' toxic algal bloom
An independent group of marine scientists from around Australia has released a seven-point plan to tackle what it describes as South Australia's "catastrophic" toxic algal bloom. The Biodiversity Council, an independent group founded by 11 Australian universities, has outlined seven key actions that federal and state governments should consider to "urgently respond" to the bloom, known as Karenia mikimotoi. It includes spending at least $10 million to immediately kick-start scientific research to assess which species are affected by the bloom, how much, and monitor recovery. It has also warned that the algal bloom is not just a South Australian issue, and the impact will be far-reaching amid increasing marine heatwaves across the country. Biodiversity Council member, professor Gretta Pecl from the University of Tasmania's Institute for Marine and Antarctic Studies, said the washed up marine life on beaches is just a sliver of the animals killed, with most animal bodies "rotting on the sea floor". "The exact death toll would be impossible to determine as monitoring of marine environments and species is fairly lacking in Australia, but we cannot wait to act," she said. The harmful algal bloom has been ravaging marine life throughout the state since March, disrupting fishing, aquaculture and tourism industries and threatening fragile coastal ecosystems. The state and federal governments this week pledged $28 million to assist in dealing with the bloom, but Federal Environment Minister Murray Watt stopped short of declaring it a national disaster. Professor Pecl said the funding was a "fantastic start" but much more would be needed. She said the scale of wildlife deaths is likely to be equivalent to the Black Summer Bushfires and the impact will be felt across borders. "Although the footprint of the harmful algal bloom at the moment looks like it's limited to South Australia, many of those species there have really important connections to the west coast and the east coast. "The damage that's been incurred … will massively exceed the boundaries of the bloom itself." The report said more than 450 marine species had been observed washed up across South Australian coastlines, with over 14,000 observations by citizen scientists. It also said while natural oceanographic conditions played a role, the crisis has also been driven by human activities. Professor Pecl said harmful algal blooms had also been highlighted many times before amid increased ocean warming. "The scale of each harmful algal bloom event seems to be increasing," she said. "If there isn't something done to mitigate, to reduce climate emissions, warming will continue and these kind of events will be more and more likely." The proposed actions for Australian and state governments to respond to the bloom, and Australia's broader marine heatwave are: The report was produced by a team of scientists from five Australian universities including, The University of Adelaide, The University of Tasmania, Monash University, The University of Melbourne, and The University of Western Australia. Biodiversity Council member, professor Nicki Mitchell from the University of Western Australia's Oceans Institute said Australia must prepare for a more "dangerous climate future". "Due to man-made climate change, the frequency and intensity of natural disasters that harm biodiversity, industries and communities will only increase," she said. "This includes not just harmful algal blooms, but also marine and terrestrial heatwaves, floods and bushfires." Professor Ivan Nagelkerken from the University of Adelaide Environment Institute said Adelaide's coast would always be vulnerable to algal blooms. "South Australia's gulfs are particularly vulnerable to algal blooms due to coastal nutrient inputs, warming shallow waters and poor water exchange," he said. "We must collectively do all we can to reduce coastal nutrient inputs and greenhouse gas emissions. "Locally, we can also build the resilience of ecosystems to recover by protecting and restoring marine ecosystems, like kelp forests and seagrass beds, to support bigger fish populations as well as absorb carbon and improve water quality." Mr Watt earlier this week said the federal funding pledged would likely go to cleaning up and research. "There will need to be some further discussions between ourselves and the South Australian government about exactly the details of how that funding is used," he said. "But it's intended to deal with a number of short-term requirements, and some of the longer-term needs that South Australia is going to face as it recovers from this event." He said it would also assist affected businesses, boosting "community awareness" and investing in scientific research. "This is an unprecedented event and one of the difficulties has been understanding exactly what its impacts are and what sort of response is required," he said.
