Explore Earth’s most fascinating natural phenomena — from earthquakes, volcanoes, tornadoes and tsunamis to mystery booms, glowing oceans, unusual ice, atmospheric optics, animal events and extraordinary processes occurring across our planet.
This natural phenomena atlas brings together the scientific guides, explainers and major topics covered by Strange Sounds. Browse by world, jump to a letter, or follow a phenomenon directly to learn what causes it, where it occurs and why it can sometimes look so strange.
What Is a Natural Phenomenon?
A natural phenomenon is an observable event, process or feature produced by the natural world. Some are familiar — earthquakes, thunderstorms, volcanic eruptions and tides — while others are much rarer, such as volcanic lightning, limnic eruptions, animal rain or ice tsunamis.
Many phenomena that initially appear mysterious can be explained through geology, meteorology, atmospheric physics, oceanography, hydrology, biology and astronomy. Strange Sounds focuses on connecting unusual observations with the scientific processes behind them.

Strange Does Not Mean Unexplainable
Natural phenomena can look mysterious without requiring mysterious
causes. A blood-red river may result from microorganisms, minerals or
sediment. A giant crater may form through collapse, thawing ground or
underground dissolution. Strange sounds may travel unexpectedly through
the atmosphere or originate from earthquakes, aircraft, explosions,
meteors or industrial activity.
Strange Sounds approaches unusual observations by asking four questions:
What happened? What natural processes could produce it? What
evidence is available? What remains uncertain?
The Atlas Keeps Growing
Strange Sounds has documented unusual natural events for years.
As older event reports are reviewed, many are being consolidated into
larger evergreen guides explaining the underlying phenomenon rather than
preserving hundreds of disconnected headlines.
New phenomena, major scientific explainers and substantially upgraded
guides will continue to be added to this atlas as the Strange Sounds
encyclopedia evolves.
