Aug 2, 2023 · At present we can’t predict earthquakes, despite the fact that geologists have sought a reliable earthquake prediction method for decades. What’s needed is a prediction that comes not minutes ...
In truth, the science of predicting earthquakes is very, very difficult. While there are often minute signals that can be detected in the seismic data after an event has happened, knowing what to ...

A forecast tells you the chance or the probability of a range of future earthquakes in a given region. This includes how big the quakes may be (their magnitude), and how frequently they will occur over a specified time period. Earthquake forecasts are built on observations of past earthquake activity, which may stretch back decades, centuries or ev...
One of the fundamental discoveries of seismology is the fact that, in a given region, there will be on average about ten times as many magnitude 2.0 earthquakes as magnitude 3.0 quakes. There will also be ten times as many magnitude 3.0 as magnitude 4.0, and so on. This relation allows us to use small earthquakes, which happen often, to forecast le...
Geological investigations extend the record of major earthquakes beyond those captured in earthquake catalogues. These studies look for evidence of ground-rupturing earthquakes along a particular fault. Take the Alpine Fault, a 600 km section of the boundary of the Pacific and Australian plates in Aotearoa New Zealand. Analysis of rocks along the f...
Our best long-term forecasts use data from earthquake catalogues and geological studies, combined with earthquake behaviour patterns and other knowledge such as geodetic models – which use GPS networks to tell us how Earth’s surface is under strain and moving as tectonic plates shift. These forecasts typically provide not just the magnitude and loc...
Jan 15, 2020 · Why can’t we predict earthquakes? If we understand how earthquakes occur, why can’t we predict when they will happen? An effective earthquake prediction includes four components: the date ...
Feb 15, 2023 · In fact, while earthquake scientists all agree that we can’t predict quakes today, there are now essentially two camps: In one view, earthquakes are the result of complex cascades of tiny ...

Oct 8, 2019 · There's currently no proven, consistent method of predicting earthquakes. So we simply can't do that. And of course, earthquake prediction is really stating specifically where. It's sort of within a limited geographical area, where an earthquake will occur, when it will occur and how large that earthquake will be.
