List of earthquakes

What tectonic plates caused the Kaikoura earthquake?

The Kaikōura earthquake occurred on the plate boundary between the Australian and Pacific plates. This is a seismically active area, responsible for creating the Southern Alps and the Kaikōura Ranges.

What caused Australia’s earthquake?

Australia’s earthquakes are caused by the sudden release of this stress when rocks deep underground break and move along a fault line. While some parts of the country are more likely to experience earthquakes than others, large earthquakes can occur anywhere across the continent, and without warning.

What caused Melbourne earthquake?

Experts say that this one was caused by Australia’s tectonic plate colliding with the Pacific plate in the Pacific Ocean; the collision generated a build up of compressive stress that, when released suddenly, resulted in the earthquake phenomenon.

Did Sydney just have an earthquake?

There were no significant confirmed earthquakes in or near Sydney in the past 24 hours. Look up quakes in the past 30 days!

Where are the earthquake fault lines in Australia?

“There are numerous young faultlines weaving their way across southern Australia, including one that goes right around the perimeter of Adelaide. There are also young faultlines running through the Mornington Peninsula outside Melbourne, the Strzelecki Ranges in Victoria and the Flinders Ranges in South Australia.

What caused the ground to shake so strongly in Kaikōura?

Lead author of the study in the publication Seismological Research Letters, seismologist Anna Kaiser of GNS Science, said the Waiau instrument happened to be directly over the rupture of the Humps Fault, which was one of the first of more than 20 faults to rupture during the earthquake.

Where was the epicenter of the 2016 Kaikoura earthquake?

The epicentre (the point on the Earth’s surface above the hypocentre) was 15 kilometres (9 mi) north-east of Culverden and 95 km (59 mi) from Christchurch. From the hypocentre, ruptures ripped northwards at a speed of 2 km per second, over a distance of up to 200 km (124 mi).

What tectonic plates make up Australia?

Australia doesn’t sit on the edge of a tectonic plate. However, the Indo-Australian plate, at the centre of which our continent lies, is being pushed to the north-east at about 7cm per year. It’s colliding with the Eurasian, Philippine and Pacific plates, causing stress to build up in the 25km-thick upper crust.

What plates cause earthquakes in Australia?

“The Australian tectonic plate is colliding into the Pacific plate in the Pacific Ocean and generates compressive stress, which when built up is released suddenly, causing earthquakes.” When a big quake occurs, like this morning, it is usually because the pressure builds up to the point that it ‘pushes’ up the crust.

Does Australia have a fault line?

While Australia is not close to any large tectonic plates, it does have faults that do cause many tremors every year.

Does Australia sit on a fault line?

Since Australia sits on top of a very stable because geologically old continental landmass in the middle of a tectonic plate (the Australian Plate) with no major active faults, it has far fewer quakes than areas near plate boundaries or major fault lines. Where do earthquakes occur in Australia?
