Two locations in southeast Queensland have experienced some significant earthquake activity in recent months. In February a magnitude 5.2 earthquake struck just northwest of Mount Perry. Over forty aftershocks were recorded in the next 24 hours and these were still being recorded six months later. As the Mt Perry aftershocks were…
Seismologist Adam Pascale explains everything you need to know about designing, installing and operating a local earthquake monitoring network. So, you want to install a network of instruments to monitor earthquake activity in a particular area. It is recommended that any seismic network has at least 4 stations, ideally in a Y-shaped…
The very first hazard report prepared by the SRC was in 1977 for Dandenong Natural Gas Tank in Victoria. This study was commissioned prior to construction of the tank, so earthquake loading was considered as a factor in its engineering. The tank has yet to undergo significant shaking due to earthquake (the largest…
The SRC became part of ESS Earth Sciences just over a year ago, one of two companies born from Environmental Systems & Services (the other being our sister company ESS Weathertech). Today marked the launch of the new ESS Earth Sciences website – a showcase of all of the products that…
In December 2013, SRC visited the island jewel of the Indian Ocean, Sri Lanka, known for its tea plantations and cricket culture. Like Australia, this small island, is located on a similar stable tectonic environment of Precambrian rock, which also experiences low seismic recurrence, although mid-sized earthquakes are known to…
The updated version of our iPad app Quick Quake is now available in the App Store. The main changes are to the screen where you Locate the earthquake – you can now vary the depth of the earthquake using a slider (particularly useful when the earthquake is very close to your…
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…
2015 sees a huge update to eqServer, with new features including: support for MiniSEED format data subscribing to data feeds from SeedLink servers user defined network maps using NASA imagery subnetworks within your main network station performance graphs home page graphics and waveform images that adapt to your web browser size ….and…
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…
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…
