Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction. Earthquakes and composite volcanoes are common at this type of boundary.

Since the 1950s, several discoveries have led to a new understanding of how the Earth works. This includes Plate Tectonics, which explains the structure of the Earth's lithosphere (outer shell) and the forces that drive changes in its structure.

Pervasive fragmentation of continental lithosphere at plate boundaries is the rule, not the exception. However, over most of the plate boundary zones of Asia and western North America, crustal motions observed by geodesy can be described well by models that use a number of rigid plates or blocks, bounded by faults that are presumed to cut the entire lithosphere.

Earth's crust does not form a single unbroken covering around the planet. Instead, it is divided into a dozen immense plates, called lithospheric plates.

Filmed in Montserrat, Haiti, Iceland, the Alps and the UK, this program provides examples and explanations of the processes, features and landforms that occur at different plate margins. The resource then looks in detail at a range of volcanic processes and landforms. It contains footage of different types of lava, examples of intrusive and extrusive volcanic landforms and illustrations of the minor volcanic forms: solfatara, fumaroles, geysers and sinters.

Through dramatisation and animated graphics, this programme clearly explains current theories regarding the structure of the Earth, and how the continents came to be in their current positions. It explores the history behind the widely accepted theory of Tectonic Plates, involving Continental Drift and Sea Floor Spreading, and then examines the alternative theory of Global Expansion. Featuring a range of geological evidence, expert opinions and even a trip back in time to visit Galileo Galilei at his home in Florence, this programme looks at how once hotly-disputed ideas can become accepted as scientific fact.

ABC Emergency

     

If you live in an area prone to earthquakes, consider how to minimise the risk of serious injury, before one occurs.

Surviving an earthquake and reducing its health impact requires preparation, planning, and practice.

Far in advance, you can gather emergency supplies, identify and reduce possible hazards in your home, and practice what to do during and after an earthquake.

Learning what actions to take can help you and your family to remain safe and healthy in the event of an earthquake.

The Guardian

What would an Earthquake-proof city look like? Earthquakes don’t kill people (generally), collapsing buildings do – meaning it is cities where the most lives can be saved. Here are their smartest ideas so far..

Protecting cities from earthquakes is still a grand challenge that needs addressing, as recent disasters in NepalJapanHaiti, and Chile confirm. Although significant progress has been made in understanding seismic activity and developing building technology, we still don’t have a satisfactory way of protecting buildings on a large scale.

Our World in Data

World Estimated annual number of significant earthquakes. A significant earthquake is classified as one that meets at least one of the following: caused deaths, moderate damage ($1 million or more), magnitude 7.5 or greater, Modified Mercalli Intensity (MMI) X or greater, or generated a tsunami.

Bureau of Meterology

Deep-ocean tsunami detection buoys are one of two types of instrument used by the Bureau of Meteorology (Bureau) to confirm the existence of tsunami waves generated by undersea earthquakes. These buoys observe and record changes in sea level out in the deep ocean.

The effects of an earthquake depend on many factors, such as the distance from the epicentre and the local ground conditions.

The objective of the State Emergency Response Plan (Earthquake Sub-plan) is to provide sources of information and to outline the arrangements for ensuring an integrated and coordinated approach to the State’s management of earthquake events, in order to reduce the impact and consequences of these events on the community, infrastructure and services.

Liberty Action Plan

Organisations and individuals are likely to face natural or manmade catastrophe at some stage. It is therefore crucial to have a plan well in advance of emergencies, in order to protect you, your employees and your customers from personal injury.
