The detonation produced a crater 1.9 km (6,200 ft) in diameter and 50 m (160 ft) deep where Elugelab had once been; [9] the blast and water waves from the explosion (some waves up to 6.1 m (20 ft) high) stripped the test islands clean of vegetation, as observed by a helicopter survey within 60 minutes after the test, by which time the mushroom ...
A delay-action bomb is an aerial bomb designed to explode some time after impact, with the bomb's fuzes set to delay the explosion for times ranging from very brief to several weeks. Short delays are used to allow the bomb to penetrate before exploding: "a delay action bomb striking the roof of a tall building will penetrate through several ...
A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb ...
A geologic section has to fulfill a set of criteria to be adapted as a GSSP by the ICS. The following list summarizes the criteria: [2] [3] A GSSP has to define the lower boundary of a geologic stage. The lower boundary has to be defined using a primary marker (usually first appearance datum of a fossil species).
A non-standard geologic time period immediately preceding the Phanerozoic Eon, divided into several eons of the geologic time scale. It spans from the formation of Earth about 4540 Ma (million years ago) to the beginning of the Cambrian Period , about 541.0 ± 1.0 Ma, when macroscopic hard-shelled animals first appeared in abundance.

OneGeology is an international collaborative project in the field of geology supported by 118 countries, UNESCO, and major global geoscience bodies.It is an International Year of Planet Earth flagship initiative that aims to enable online access to dynamic digital geological map of the world for everyone.
Each bomb will also have a countdown timer; if the timer reaches zero, the bomb will explode. Bombs will also have a maximum number of strikes resulting from errors made during defusing (also speeding the timer), and if that maximum is reached, the bomb will also explode.
