A landmark year for California earthquakes, 2019 was full of disaster, sans-preparedness. UC Berkeley's Seismological lab is working to give people state-wide a heads-up next time a quake comes their way — seconds before they can even feel the shaking. The proposed solution lies within the new MyShake app.
"The [shaking] detection system is called ShakeAlert, underlying the entire system," said Richard Allen, director of the lab. "Once an alert has been generated, the MyShake app delivers that alert to individuals."
After MyShake, which is similar to apps covering other parts of the world, identifies which phones are in the earthquake's reach, it pushes an alert out to those close enough to feel the shaking based on phone location.
The technology is still a work in progress. California has a ShakeAlert service solely for Los Angeles as well — but it didn't pay off during July's surprise earthquakes when many people complained they weren't notified.
"What happened [in LA] was an important lesson to be learned by everybody involved in earthquake early warnings," Allen said. "What happened in Ridgecrest was the threshold for when an alert gets pushed out to phones was set up relatively high at shaking intensity four. The ShakeAlert system didn't estimate that there was going to be shaking at level four across L.A."
The MyShake app is programmed to recognize a much lower level of shaking, making it more likely that Californians will receive a warning notification next time an earthquake is on its way. West Coasters can download the app on both iPhone and Android to be eligible for alerts.
Heavy rainfall flooded parts of Massachusetts and Rhode Island, with two communities declaring a state of emergency as water poured into homes, creating moats around their foundations and leading to boat rescues of residents. Concern about a dam listed in poor condition led to more evacuations.
The leading decongestant used by millions of Americans looking for relief from a stuffy nose is no better than a dummy pill, according to government experts who reviewed the latest research on the long-questioned drug ingredient.
Hurricane Lee, still a Category 3 storm with winds of 115 mph, is expected to increase in size but be significantly weaker in the coming days, as it turns north to reach the U.S. East Coast, according to the National Hurricane Center.
The U.S. approved updated COVID-19 vaccines Monday, hoping to rev up protection against the latest coronavirus strains and blunt any surge this fall and winter.
An earthquake has sown destruction and devastation in Morocco, where death and injury counts continue to rise as rescue crews dig out people both alive and dead in villages that were reduced to rubble.
Hurricane Lee whipped up waves of more than 15 feet (5 meters) on Monday as the Category 3 storm cranked through open waters just north of the Caribbean region.
