Certain, Confirm
たしか (tashika), たしかめる (tashikameru)
Interesting Fact
Japan's earthquake early-warning system can sometimes detect an earthquake and send alerts before the strongest shaking reaches a particular location. 📱⚡ Sensors detect the initial seismic waves and rapidly estimate the earthquake's location and intensity. This can give people precious seconds to react—such as stopping trains, slowing elevators, or taking cover. It doesn't predict earthquakes before they happen; instead, it rapidly confirms that an earthquake has begun and warns places that haven't yet experienced the strongest shaking.
Memory Trick
“A stone(石 ) is measured from every side to confirm its exact weight—that's 確!”
