US tsunami warning system needs an urgent overhaul, experts say
CNN
Earlier this year an underwater volcano erupted in Tonga, triggering a widespread tsunami. While advisories were issued, there was confusion at the time because the event wasn't triggered by an earthquake, which tsunami forecasting models don't take into account.
And last week a 7.4 magnitude earthquake in Japan sparked tsunami alerts across the country. The Japanese tsunami system worked very well, issuing alerts within minutes of the earthquake.
But how would have the US Tsunami Warning System handled a similar situation?
Tulsi Gabbard, Donald Trump’s pick to lead the intelligence community, was briefly placed on a Transportation Security Administration list that prompts additional security screening before flights after her overseas travel patterns and foreign connections triggered a government algorithm earlier this year, three sources familiar with the matter told CNN.
