What do underwater volcanic eruptions sound like?

What do underwater volcanic eruptions sound like?

Buried in the depths of the oceans, over a million enormous underwater volcanoes puncture the seabed. Scientists have recorded their eruptions with some surprising results. Ahyi—in the Northern Mariana Islands in the Pacific Ocean—erupted for two weeks in 2014. Experts compared the sound of its eruptions to gunshots. Bogoslof, a shallow volcano in the Aleutian Islands near Alaska, sounded completely different when it erupted in 2016 and 2017. Vibrations can travel for thousands of miles before dissipating. It is very difficult to detect early signs of submarine eruptions, which can produce blankets of floating rocks, damaging boats and clogging harbors. Recording their sounds could help experts respond more quickly. Dec 5, 2017

US flies two dozen stealth jets over Korean Peninsula for massive drill

Hundreds of warplanes and several weapons began training as the US and South Korea embarked on a massive aerial drill on Monday, 4 December, in a strong show of force against the reclusive North Korean regime. The joint drill, codenamed Vigilant ACE (air combat exercise), is taking place within days of Pyongyangs launch of a new intercontinental ballistic missile (ICBM), although the exercise was scheduled before the Norths provocative act.
