Kalgoorlie-Boulder earthquake


A magnitude 4.6 earthquake shook Kalgoorlie-Boulder residents on the morning of Wednesday 26 February 2014, shaking buildings and parked cars and causing minor damage near the epicentre.

The event occurred 30km west of Kalgoorlie-Boulder, Western Australia, at 8:03am local time. Since the initial earthquake 15 aftershocks have been recorded, but were too small to be analysed.

Geoscience Australia received more than 70 felt reports from the area, describing minor damage to houses, falling pictures and crockery, and swaying of buildings. Felt reports came from as far away as 120km from the epicentre.

It is the second largest earthquake on record for this region, following the magnitude 5 event in April 2010, which caused major structural damage to buildings and infrastructure.

Detailed investigations by Geoscience Australia following the 2010 earthquake revealed hazard vulnerabilities, in particular for Pre-World War One infrastructure.

There is a simple online earthquake report form that can be filled in on the Geoscience Australia website. It includes a series of questions to obtain information about shaking windows, loud noises or any immediate building damage. This information assists seismologists in gaining a greater understanding of this naturally occurring Earth process.
