A Brief History of Australia Earthquakes by State
We’ve compiled a short series of clips highlighting a few interesting earthquake facts for each Australian state and territory into a single video.
Dynamic Analysis of a Dam using Strong Motion Accelerograph Data
As part of the operation of the Victorian Water Industry seismic network, the Seismology Research Centre recently installed triaxial strong motion accelerographs (SMA) on Glenmaggie Dam.
Two years on from Victoria’s largest earthquake
Two years ago today, at 9:15 am, a few million people in southeast Australia felt an earthquake, many for the first time in their lives. Let’s cover some of the more interesting points about this earthquake. Despite being felt by millions of people, only about 43,000 reported what they experienced…
SRC earthquake data live on YouTube
The SRC is now streaming live earthquake data to our YouTube channel. The selection of stations covers southeast Australia, so if you’re in the region and there’s been something large enough to feel, you should be able to see it on some nearby stations. Each line shows the last hour…
Magnitude 4.0 Earthquake in Melbourne’s North
The magnitude 4.0 earthquake on 28 May 2023 at 11:41pm, whose epicentre was located near the outer northern Melbourne suburb of Craigieburn, was recorded on dozens of seismometers and accelerometers across the state, providing a plethora of data for seismologists to analyse how ground motion changes over distance.
Earthquake Alarm Service for Victoria
Victoria is one of the most uniformly monitored states in Australia for earthquake activity, growing from a small research project run by the Preston Institute of Technology to a network with statewide earthquake alarm capabilities.
Human Activity Can Trigger Earthquakes
Earthquakes occur when stress build-up in the earth’s crust exceeds the strength of the rock, but tectonic plate motion isn’t the only source of stress. We can change rock stress and trigger earthquakes to occur sooner than they may have otherwise.
Faults: Normal, Reverse, or Strike-Slip?
What are faults, what do the different types of fault mean, and what has that got to do with the SRC logo?
Locating the Origin of an Earthquake
When you feel the earth shaking, it might feel like the earthquake is right under you, but it’s likely that the earthquake started dozens of kilometres away.
Negative Magnitude Earthquakes
How can an earthquake have a negative magnitude? It’s got to do with ground motion and distance, and how sensitive seismographs have become.
