Your mobile phone could soon warn you of earthquakes. How does it work?
Google is launching its Android Earthquake Alerts System in New Zealand and Greece but what information does it draw on, and how useful will it be for an quake-prone country such as ours? Mirjam Guesgen explains.
What does this earthquake alert system do?
Android phones will operate as earthquake detectors and show a warning alert that shaking is about to happen.
How much warning people will get depends on how far you are from where the earthquake originates. If you’re further away you might get 10 seconds or more warning, if you’re only a few kilometres from the source, that warning might only be a second or two.
Researchers mobilise citizen-scientists for community Earthquake Early Warning System
Lead researcher Dr Raj Prasanna shows some of the low-cost seismic sensors that his team has been testing.
The Joint Centre for Disaster Research at Massey University is leading a project aiming to develop a low-cost community-based earthquake early warning system in New Zealand.
The project, co-funded by Massey University and the Earthquake commission (EQC), is sourcing a number of low-cost seismometers and working with a number of communities to see if they would be willing to become part of a research project aiming to trial an earthquake early warning sensor network.

Scientists are calling on New Zealanders to become
citizen seismologists to help determine whether a low-cost
community-based earthquake early warning system is feasible
in New Zealand.
The project, co-funded by EQC and
Massey University, has enabled a group of scientists, led by
the Joint Centre for Disaster Research at Massey University,
to source a number of low-cost seismometers and work with a
number of communities to see if they would be willing to
become part of a research project aiming to trial an
earthquake early warning sensor network.
“At
present, there is no earthquake early warning system in New
