Why you didn’t get an alert about any of the recent earthquakes
For those users who signed up for alerts in the past wondering why none popped up on their phones after the last four earthquakes, that’s because they weren’t big enough seismic events. The magnitude 4.0, 3.0, 2.7 and 2.6 earthquakes fell under the threshold needed to trigger automated alerts.
“For some of the apps, like , which you can download on your phone, that’s still set at a magnitude 4.5 threshold and this didn’t quite meet those thresholds,” Harold Tobin of the PNSN told ³ÉÈËXÕ¾ Newsradio after a magnitude 4.3 earthquake hit the region in October 2023.
