Earthquake Mapping Tool

Over the past two decades the world has seen a number of earthquakes affect large sections of the world's population, bringing devastation to cities and causing tsunami in the Pacific and Indian Oceans.

These large geological events occur at the boundaries of the Earth's tectonic plates which are continuously moving relative to each other). Effects of these dynamic processes can be felt regularly in countries such as neighbouring New Zealand, Vanuatu, the Solomon Islands, Papua New Guinea, Japan, the Americas, and Indonesia, as they lie on plate boundaries surrounding the Pacific Ocean - this region is known as the 'ring of fire'.

Fortunately the Australian continent sits in the middle of the Indo-Australian tectonic plate, making us much less likely to experience the large, destructive earthquakes than the countries listed above. However, we still need to understand the history of earthquakes in Australia and their associated risk to make sure our building codes and emergency response plans are adequate.

The earthquake mapping tool provides extremal access to Geoscience Australia's internal EARTHMON database. Users can use the search tool to extract earthquake data based on date, location, depth, magnitude and significance.

- What further uses can you find for this data?
- Can you show all recorded Australian earthquakes through time?
- Can you combine the dataset with satellite imagery to show the before and after of larger earthquake events?
- How useful can social media be in mapping when people feel earthquakes?
