Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Earthquakes In Western Australia
Earthquakes have occurred in Western Australia (WA) on a regular basis throughout its geological history. In 1849, the first earthquake following European settlement in WA was recorded. "On Saturday last, about a quarter past four o'clock a.m., several inhabitants of Perth were awoke by what they conceived to be a slight shock of an earthquake." The largest earthquake affecting Western Australia in modern times was an offshore earthquake in 2019, occurring 202 km west of Broome at a magnitude of 6.6 causing minor damage in the town itself. The strongest earthquake with its epicentre on land is the magnitude 6.5 Meckering earthquake of 1968, which caused injuries to at least 17 people and extensive property damage; it was the best-known earthquake in Western Australia the late twentieth century. The previous largest earthquake documented occurred in 1941, at Meeberrie, in the Murchison region. Like many earthquakes it remained little known, due to its lack of impact on u ...

Department Of National Development (1950–72)
The Department of National Development was an Australian government department that existed between March 1950 and December 1972, and briefly between December 1977 and December 1979. History The Department of National Development was established in March 1950, with Richard Casey, Baron Casey as its Minister. Media reported that the new Department would plan for the supply of basic commodities, promote decentralisation and regional development and plan for the development of primary and manufacturing industries and the stimulation of housing construction. By 1969, the Department consisted of five divisions: the resources policy division; the northern development division; the Bureau of Mineral Resources; the Forestry and Timber Bureau; and the division of national mapping. The Department was one of six abolished by the Whitlam government in December 1972. It functions were split between four new departments, namely the Department of Environment and Conserv ...

International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collecti ...

South West Seismic Zone
The South West Seismic Zone (also identified as SWSZ) is a major intraplate earthquake province located in the south west of Western Australia. It was known earlier as the ''Yandanooka – Cape Riche Lineament'', corresponds to the physiographic boundary known as the ''Meckering Line'', and also the junction between Swanland and Salinaland. The zone exists within an Archaean Shield structure called the Yilgarn Block. The identified geological subdivisions within this Precambrian structure do not show an obvious relation to the seismicity. The zone represents a significant seismic hazard to Perth. More than six thousand earthquakes have occurred in the SWSZ in the years 1968 – 2002. Meckering, Cadoux and Burakin earthquakes originated in the SWSZ. More recent events have occurred to the south in Lake Muir in 2018 and Arthur River in 2022. The zone and the explanation of it, has been titled ''Perthquake'' in the ''Catalyst'' programme on the ABC in 2001. Temporal varia ...

List Of Earthquakes In 1968
This is a list of earthquakes in 1968. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. There was a large resurgence in activity in 1968. 22 magnitude 7.0+ earthquakes struck various parts of the planet. The largest of these was a magnitude 8.2 event in Japan in May. Large aftershocks struck the area following the mainshock. New Zealand and Indonesia had some upheaval during the year. The high activity contributed to over 12,000 deaths across the world. The vast majority of this total was caused by a destructive event in Iran in August with nearly 10,500 deaths. Events in the Phi ...
