Seismoscope
Read full descriptionHide full description
Seismoscope is designed as a fast and simple way view recent earthquakes near you, particularly for Australia. Earthquake data is sourced from the Seismology Research Centre (SRC, for the last 30 days), Earth Sciences New Zealand (GeoNet, last 100 events), and data from the last week is shown from Geoscience Australia (GA), GFZ Helmholtz Centre for Geosciences (GFZ), the U.S. Geological Survey (USGS), and the European-Mediterranean Seismological Centre (EMSC). Earthquakes that have occurred in the last 3 hours pulsate to highlight recent activity, and events older than 7 days are less prominent. For ease of interpretation, earthquakes are colour-coded as well as being sized by magnitude. Links to report Australian earthquakes to GA are available directly in the app, as are links to notify GeoNet, USGS, EMSC and GFZ events via their respective reporting pages.
