Many Victorians claim their cat or dog was acting strangely before yesterday’s earthquake. And while there’s no real evidence animals can predict a quake, they may be more sensitive to very tiny ones.

When will the next earthquake come? We don’t know, but that doesn’t mean we can’t get our cities ready.
A largely hidden fault beneath the Victorian Alps has triggered a magnitude 5.8 quake that was felt as far afield as Sydney, Adelaide and Launceston. Here’s what we know so far.
The geological record tells us we have had earthquakes in Australia’s deeper past much larger — possibly up to and bigger than magnitude 7.0.
8,000 tonnes of molten iron solidifies in Earth’s inner core every second – but it’s not distributed equally.
Mars’ core is larger and less dense than we thought.
Aftershocks of a major earthquake can continue for years or even decades.

Earthquakes can be caused by human, or seismic, activity. Is South Africa adequately prepared?
California was thought to be an exception, a place where oil field operations and tectonic faults apparently coexisted without much problem. Not any more.
We might not be able to predict the next big earthquake, but we can make sure we’re ready for it and understand the risks.
A big dip in the Earth’s crust may record an ancient continental collision from the dawn of plate tectonics.
Measuring seismic noice could show whether people are following future lockdown measures.
A network of sensitive instruments in schools around Australia is recording the eerie silence of the coronavirus pandemic — and tiny earthquakes that would otherwise be undetectable.
Puerto Rico’s January earthquakes came after many foreshocks and have been followed by numerous aftershocks. Scientists are studying these sequences to improve earthquake forecasting.
A tricky kind of earthquake that happens in the soft rock of the ocean floor causes much larger tsunamis than their magnitude would predict. New research pinpoints a way to identify the danger fast.
Post-earthquake aftershocks are often assumed to be less violent, but that’s not always the case.
There are three important issues to consider when thinking about quakes: what causes them; how to prepare and plan for them; and, how to move on after a damaging quake.
Engineers know how and where to build to minimize earthquake damage. But laws don’t always reflect that wisdom. A new study suggests it’s because of a mismatch between risk perceptions and reality.
Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.
North Korea is a major military threat to the US and its Asian allies, but exactly how powerful are its nuclear weapons? An earth scientist explains why it’s hard to answer this question.
