A ground wave is a condition in which the solid ground ripples and moves in waves, the way water in a pool will ripple when a rock is tossed in. In real life, this can only happen as a result of a nuke bomb detonation or a huge explosion (see the PEPCON disaster under Real Life, below). In movies, some character with either superpowers or incredible strength strikes the ground - or the opponent it is fighting throws them at the ground - so hard that the ground rolls, ripples and moves in response. See Shockwave Stomp.
Note, if the landing just creates a big hole and not a ripple effect, it's a Ground-Shattering Landing.
- An ad for DirecTV shows "The World's Most Powerful Fan," who, when playing pick-up ball, jumps over another player and causes a ground wave that bounces everyone else.
- From 2014 onwards, BMW ran an advertising campaign called "Embrace the Unknown" or "The Wave" which showed the whole world rippling, undulating, and rolling like an ocean, with two released so far:
- In the advert for the BMW X4, it showed the car driving through several waving cityscapes, with the buildings constantly shifting up and down from the waves, while occasionally cutting to people doing various activities. At one point, it cut to an interior shot showing balls rolling around on a pool table due to the room tilting from a wave rolling underneath the building.
- In the advert for the BMW X1 in the following year, it showed the car driving across several heaving landscapes, riding over bumps and even dodging an enormous waterfall spilling over a mountain edge as it pulses, before arriving at the city from the previous advert.
- In The Legacy of Luther Strode #1, Luther's Hulk-meets-Wuxia fight with the female Twin does this to asphalt and concrete as they leap and land and punch each other through buildings and overpasses.
- In Robert A. Heinlein's The Moon Is a Harsh Mistress has the lunar colonists who rebel against earth's government to throw rocks, basically steel-cased house-sized boulders. It's noted they'll create a huge hole, a ground wave and a blast wave due to the air being compressed at the strike point. One strikes with so much force the impact can be seen with the naked eye all the way back on the moon!
- Occasionally happen when earthcrafters get to work in Codex Alera. They also use this as a form of ground transport by making the ground under your feet travel in a slow, continuous wave. Beats walking.
- The Fantastic Four happens to the heroes and the villain as they keep trying to kill each other.
- The Matrix has this in several places, when Neo strikes the ground when fighting Agent Smith, or some of the other characters cause this when making a jump or landing on a building or the freeway.
- War of the Worlds (the one with Tom Cruise) has a scene where the tripods ram an invasion force into the ground, tearing up the entire area.
- In Mario & Luigi: Superstar Saga, at least one of the Koopalings causes ground waves by stomping when the heroic brothers fight him.
- In Mario & Luigi: Partners in Time:
- During the Swiggler boss fight, the boss will counter with several damaging shockwaves that take the form of the ground rippling if attacked head on.
- When the Trampoline attack item is being used, the entire ground briefly ripples and jiggles for every successful stomp preformed, even if the current target is floating in midair.
- In The King of Fighters, Terry's Power Wave move sends a wave of energy along the ground. Likewise with Iori's (and occasionally Kyo's) Yami Barai move.
- In Minecraft, one of the many Game Mods allows you to use custom shaders. One particular shader, called "The Wave", causes the entire world to undulate and roll.
- Mario Kart:
- Mario Kart Wii has the battle course Thwomp Desert, featuring a huge Thwomp in the middle of the arena. Every so often it slams down, causing huge waves that ripple outwards, throwing karts around.
- In Mario Kart 7, SNES Rainbow Road has Thwomps that cause the track to ripple when they slam down, which didn't occur in the track's original version.
- In Thumper, stomping on a thump or attacking a boss sends a wave of energy running down the track.
- In the first Yoshi's Island game:
- Warcraft III: The editor allows for this to happen (and the Shockwave spell briefly distorts the ground when used), but no official map uses it (possibly because it's quite a trippy effect to see units minding their own business while bobbing like toy ships in a wave pool).
- Battlezone and the 98 Redux has two forms of this, first being the Thumper special weapon that dumps a large amount of your Hover Tanks nano-ammunition into the ground, causing a travelling lump of terrain that upends and spins vehicles caught in the path and it's particularly effective at spinning walkers around, leaving them unable to target you until they land. The Day Wrecker bomb launched by the Supply Launch Facility (Armory) also causes a short, circular wave in the terrain when it detonates.
- The PEPCON perchlorate processing plant in Henderson, Nevada (just outside Las Vegas) generated one of these after a chain of Disaster Dominoes when several drums of Ammonium Perchlorate, also known as the oxidizer component of rocket fuel, were inadvertently exposed to an ignition source (with the exact cause still a matter of debate). This triggered a Chain Reaction Destruction sequence over the course of several minutes that lead from these drums to the precursor chemical storage bins to the plant's shipping storage bay which held approximately 4500 metric tons of Ammonium Perchlorate and sat over an incorrectly marked natural gas transmission line. The largest of the 5 major explosions was so strong it reached a Richter scale reading of about 3.5. Video from a camera several miles away showed the ground rippling outward from the blast site. The shockwave occurring after the blast can be seen in this YouTube video at about 58 seconds: https://www.youtube.com/watch?v=_KuGizBjDXo
- Tidal forces affect not only water, but solid ground as well, though it's too subtle to be noticed without the aid of special devices. Still, twice a day a two-foot tidal Ground Wave travels beneath your feet.
