“• Fire is responsible for over 50 % of alerts for County of San Diego, California, USA.
• App installation rates closely mirror the timing of hazard events.
• Multi-hazard apps retain users at a 15 % higher rate compared to single-hazard apps.
• Higher retention improves likelihood people will receive an alert for low-frequency high-impact events like earthquakes..."

#Google’s #earthquake early #warningsystem #failed to accurately alert people during #Turkey’s deadly earthquake in 2023. The system underestimated the magnitude of the earthquake, resulting in only 469 “Take Action” warnings sent out instead of the potential 10 million. Google researchers have since improved the system and it is now available in nearly 100 countries. https://www.bbc.com/news/articles/c77v2kx304go?eicker.news #tech #media #news

@KimPerales "#KerrCounty Sheriff Larry Leitha said sending out warnings isn’t “as easy as pushing a button.” Answers about who did what when will come later. Kerr County Judge Rob Kelly, county’s chief elected official, said in hrs after devastation that county does not have a #warningsystem. Generations of families in the Hill Country have known the #dangers. 1987 flood forced the #evacuation of a youth camp in town of Comfort, swamped buses and vans. 10 teens killed. #negligence #climatecrisis

A GOP state lawmaker who represents Kerr County says he likely would vote differently now on House Bill 13, which would have established a grant program for counties to build new emergency communication infrastructure.

Elected politician in these regions failed to warn the population on time.
The AEMET already warned authorities since Tuesday 28 of October but Valencia right-wing (PP) "climate skeptics" governor, Carlos Mazón, didn't trigger the warnings until 8:30 PM.
The population was already trapped by that time.
Many business still demanded employees to keep doing their job!
