Biggest exposed crack on Earth's crust seen for the 1st time
Geologists have for the first time documented the Banda Detachment fault in eastern Indonesia, the biggest crack in Earth's crust. The fault represents a rip in the ocean floor exposed over 60,000 square-kilometres. The 7.2-km-deep abyss runs through the 'Ring of Fire', an explosive region where 90% of all earthquakes occur and 75% of all active volcanoes are found.
