Earthquake Early Warning

I heard Oregon was getting a new earthquake early warning system, how does it work exactly ? Why is it not possible to get it everywhere ?

Yes indeed!!

ShakeAlert, the USGS Earthquake Early warning system is now available in Oregon. You can learn all about it here : Oregon activates mobile earthquake warning system -

What’s really important is to differenciate Earthquake Early warning and earthquake prediction. We still can’t predict earthquakes but we can try to alert people as soon as we detect p-waves, in order for them to be alerted before they actually feel S-wave !

These are still developping system and are not available everywhere but they are real progress for risk reduction !

If you have friends, relatives staying nearby the sea or volcanoes please tell them be vigilant of earthquake and tsunami ![:confounded:]
