Ecotech captured unique details of the Victorian earthquake at one of its live blast monitoring sites.
After a magnitude 5.3 quake shook Gippsland and many parts of Victoria, there were 60 aftershocks, making it the largest quake in the state in more than a century.
Ecotech business specialist blast monitoring Ashlea King said the site recorded a maximum vibration of 6.69 millimetres per second for the main quake and also picked up several small aftershocks.
The Ecotech system consists of remote blast monitoring stations known as Dynamates that are continuously monitored by remote software at the company’s Melbourne head office.
Results of the blast are automatically collected and available to customers within minutes of the event.
The company has installed more than 100 systems in the past 18 months.
The waveform or graph that is available shortly after a blast captures details of the overpressure using an airblast microphone and ground vibration using a triaxial geophone.
Customers can view results, produce reports and interact with software via a web browser anywhere or any time.
The system is useful because it provides near instant notification of ground movements associated with earthquakes that may seriously impact on power plants, paper mills, train lines, gas transmission pipelines and other large infrastructure.
This knowledge of ground movement allows owners and operators to make better decisions on shutdown or inspection requirements prior to incurring significant damage from undetected failures.
