Events

What happened, where and when

Eclipses, earthquakes, volcanic eruptions, tsunamis and fireballs appear at their place and time. Let the Time Shuttle run and you see them come and go.

Eclipses

Kugelblitz computes solar and lunar eclipses from the motion of the Sun and the Moon instead of reading them from tables. The Moon's shadow crosses the Earth and takes its light away; on the Earth stand the central line, the limits of totality, the edge of the partial zone and the lines of equal coverage. In a lunar eclipse the Earth's shadow turns the Moon copper red.

Earthquakes, eruptions, tsunamis, fireballs

Earthquakes since 1900 from the USGS catalogue, older ones from NOAA's database, and the moonquakes of the Apollo seismometers and InSight's marsquakes. A quake can be seen from as far as it was felt, in the colour of its depth. Volcanic eruptions come from the Smithsonian's Global Volcanism Program, tsunamis from NOAA, fireballs from NASA. The time span goes from one day to a hundred years, or unlimited.

Where the wave arrived

In a tsunami the coasts light up at the moment the wave arrived there, as NOAA recorded it. So the wave's way across the ocean becomes visible.

The list

The “Time” window lists under “Events” the eclipses, quakes, eruptions, tsunamis and fireballs around the globe's moment, their severity as a bar, along with every mission that reached the Moon and Mars. A click sets the time and flies there.
