This event of the week is really more of a “monitoring and mitigation tool” of the week: the Earthquake Early Warning (EEW) system. This potentially life-saving tool has been in the news recently as the US government prepares the next budget. But, what is it exactly, how does it work, who would it help save, and where has it been used successfully? I think that it is important for us all to be aware of the science behind the EEW and to also be aware that there are countries that already have early warning systems and that they have already proven to be successful. So, for this week, I would like us all to learn more about the status of EEW in the US, how it would work, what type of seismic network is needed, and compare/contrast where we are in the stage of development versus other countries that already have this type of system operational.
- Read all the earthquake early warning system sections on the following webpage: https://earthquake.usgs.gov/research/earlywarning/
- Briefly, how does the early warning system work?
- List the countries that currently have early warning systems in place (hint – the US does not yet have a fully operational version so should not be included in this list)
- See if you can find a recent example from the news where an early warning system alerted people ahead of an earthquake – how much time did they have to take cover? What type of alert was used (text, siren, combination?)
