A change that is at some place during time.

- Computed level: L2 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: generic  ·  Arena: space.extent, time.dimension, energy.capacity, pattern.regularity

## Emergence
**Emerges from:** [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension)

**Through:** Change located at a place and ordered in time.

**Novel properties:**
- event occurrence
- temporal location

## Examples
- The 2011 Tōhoku earthquake shifted Japan's coastline by up to 4 meters instantly. *(geology)*
- The launch of the Higgs boson detection at CERN's Large Hadron Collider occurred on July 4, 2012. *(physics)*
- The first iPhone was unveiled by Steve Jobs at Macworld 2007 in San Francisco. *(technology)*
