Friday’s magnitude 7.2 earthquake in the Mexican state of Oaxaca was another opportunity to demonstrate the benefits of an earthquake early-warning system, which in some seismic events, can send an alert ahead to cities before damaging waves can reach them. That means that in a place like Mexico City, which is built atop the weak soils of a former lakebed, people there had an approximately 1-minute warning to move outdoors and away from buildings or take shelter in a sturdy location before the shaking started.

When a major storm rolls into an area, there are often numerous citizens who believe the storm will be dangerous. Then there’s the second camp — the more dangerous camp — who may not believe the storm will be all that intense and do not effectively prepare themselves for the storm.

For emergency managers, people who are unprepared for emergencies creates a number of problems. For instance, lack of citizen preparation creates dangerous situations for public safety employees.

These local residents may not believe they need to prepare, because they think that they will still have access to numerous resources during a disaster. Social scientists often pinpoint this type of behavior to determine whether there is a behavior pattern that can be altered.

Emergency managers have long posited that more education helps individuals to know how they can effectively prepare for a disaster. But education often only goes so far — it does not take away the need for disaster preparation.
