Drill-and-detonate plan: researchers propose nuking approaching asteroids to avert catastrophe

Chinese scientists from the China Academy of Launch Vehicle Technology propose a defense against large near-Earth asteroids by drilling into an incoming rock and detonating a nuclear device about 100 meters deep. Computer simulations suggest a 300-kiloton explosion could destroy a small asteroid (~164 feet), while a 3-megaton blast could destroy a much larger body (~1,000 meters), with effectiveness depending on size, speed, and depth of detonation. Real-world viability would require early threat detection and a mission capable of delivering drilling and nuclear hardware into space, adding to ongoing discussions of nuclear options alongside other defenses like NASA’s DART.

Inside-Out Nukes: A New Plan to Stop Large Asteroids

Chinese researchers propose using a nuclear blast to destroy or rapidly deflect a large asteroid by carving a crater and detonating a warhead inside; their models favor a pre-excavation detonation for deep energy transfer, potentially making this approach more effective than surface-only hits for rocks around 100 meters in size and offering two defense modes: direct-impact detonation and pre-excavation detonation.

Tonga volcano eruption surpasses nuclear explosion in power, triggers mega-tsunami.

Tonga volcano eruption surpasses nuclear explosion in power, triggers mega-tsunami.

The eruption of the Hunga Tonga-Hunga Ha’apai volcano in Tonga last year was likely comprised of five blasts, with the last one releasing energy equivalent to about 15 megatonnes of TNT, making it comparable in magnitude to the most powerful nuclear detonation by the US. The event involved both eruptions and explosions of steam, which caused sonic booms and a related tsunami. The tsunami was not as deadly as expected due to the location of the main settlements in Tonga, which safely faced Nuku’alofa Lagoon, and the closure of tourist resorts because of Covid.
