How small earthquakes affect Seismic Hazard

SRC seismologists explain the importance of having a complete earthquake catalogue for hazard studies for low seismicity areas.   In intraplate areas of low seismicity, such as Australia, the magnitude completeness of an earthquake catalogue is particularly important in Probabilistic Seismic Hazard Analysis (PSHA) studies. The completeness magnitude, Mc, refers to…

Energy Groups Study Quakes Around Gas Fields

The SRC has been engaged by a consortium of energy companies to monitor the seismicity in the North Perth Basin around several natural gas fields. Some of these fields, around 300km north of Perth, were discovered in the 1970’s and 80’s, and now, due to advancements in hydraulic fracturing technology, present potentially commercially viable…

Jenolan Caves earthquake vault recommissioned

After 30 years sitting unused, one of the earliest earthquake monitoring vaults in Australia has recently been recommissioned as an operational seismic station with a modern seismograph using GPS timing and 3G data telemetry. Originally commissioned in 1959 along with two other underground vaults in the Burragorang and Upper Nepean State Parks, the Jenolan vault formed…
