Earthquake Lists

Some interesting lists of earthquakes in Australia and internationally.


Earthquake Mapping Tool

The earthquake mapping tool allows you to: * view recent earthquakes which occurred over the past 30 days * search and explore all Australian earthquakes * search and explore earthquakes worldwide * view seismograms of earthquakes over the past 90 days * advise Geoscience Australia when you have felt a recent earthquake.


Exploring for the Future Data Discovery Portal

Exploring for the Future Data Discovery Portal provides free access to new geoscience data and tools acquired and developed during the eight-year (2016-2024) Exploring for the Future program investigating the mineral, energy and groundwater resource potential in Australia. The portal provides the ability for government planners, regulators and industry to access new data and apply a range of assessment tools to support evidence-based decisions.


Geochron Delivery System

Geoscience Australia's Geochron Delivery system is the retrieval system for geochronological data stored by Geoscience Australia. The system will be continually updated as the volume, variety and quality of available geochronological data increase. The initial (September 2011) release contains only ion microprobe (SHRIMP) data, comprising data from about 560 samples, chiefly derived from Geoscience Australia's previous Geochronology OZCHRON. Migration of further OZCHRON data, and upload of more recent data (including analyses obtained in collaboration with the States and the Northern Territory under the National Geoscience Agreement) is ongoing and continuous.


Geochronology and Isotopes Data Portal

The Geochronology and Isotopes Data Portal provides access to compilations of 1) publicly-available radiometric age results and 2) full analytical data tables for publicly-available isotope data, from both Geoscience Australia and literature-compiled sources as well as suite of analytical tools to maximise the value of the data. Each result links to information about the sample (including unit name, lithology and age), sample collection site, method of analysis, analytical errors, associated Reference Standards and analytical values (full analytical datasets only), and references for location, age data, and the source publication information.


Geographic to Grid - Redfearn's Formulae

Geodetic Calculations - Redfearn's Formulae, Geographic to Grid Given Latitude and Longitude, calculate Easting, Northing, Zone for a Universal Transverse Mercator (UTM) projection, Grid convergence and Point Scale Factor.


Geophysical Archive Data Delivery System

Geophysical Archive Data Delivery System (GADDS) provides magnetic, radiometric, gravity and digital elevation data from Australian National, State and Territory Government geophysical data archives.


Grid to Geographic - Redfearn's Formulae

Redfearn's Formula, Grid to Geographic Given Easting, Northing and Zone for a Universal Transverse Mercator (UTM) projection, calculate Latitude, Longitude, Grid convergence and Point Scale Factor.


Interactive Maps

Interactive Maps is a discovery and exploration view of Geoscience Australia's geospatial services. The following scientific and decision support themes have curated content comprised of maps and functions. Each map has queries and functions with linked access to OGC (Open Geospatial Consortium) web services and metadata. This system replaces MapConnect and AMSIS applications.


K Indices from Australia

The k index is a quasilogarithmic index of geomagnetic activity relative to an assumed quiet day curve for the recording site. k is a code from 0-9 that characterizes magnetic activity (0 being the least active field and 9 the most active field) over a 3 hour period.
