It's worse than that.

> After the earthquake Google's researchers changed the algorithm, and simulated the first earthquake again.

> This time, the system generated 10 million Take Action alerts to those at most risk – and a further 67 million Be Aware alerts to those living further away from the epicentre.

So, basically, Google learned from the data, improved the algorithm, and they are blamed for not having done that before the earthquake.

The headline makes it sound like Google had the good model before, and something went wrong in the notification system so nobody got the alert.
