For an event inside the event horizon of a black hole, the future light cone lies inside the event horizon. Therefore the answer in classical gravity is no, gravitational waves cannot escape from a black hole. kodama said:

If the wave is long, it does not have much energy; if it is short, it has a lot of energy. Radio waves do not have much energy, and that means they travel in big waves with long wavelengths. shipping from california to virginia

WebMay 16, 2024 · Black holes themselves are completely dark, since nothing, not even light, can escape their gravity. But black holes are surrounded by clouds of gas, and astronomers can measure this... WebRadio telescopes look toward the heavens to view planets, comets, giant clouds of gas and dust, stars, and galaxies. By studying the radio waves originating from these sources, astronomers can learn about their composition, structure, and motion. Radio astronomy has the advantage that sunlight, clouds, and rain do not affect observations.
