Playback
Keep your camera view, slow down, show map popovers and briefly shake at significant earthquakes
Column height shows relative energy, not damage or risk. Selecting a column opens its largest quake.
Balanced keeps the records while quieting overlapping waves and background glow.
Bars provide a relative comparison derived from catalogue magnitudes, not measured energy. Different magnitude scales are not equivalent.
Space: play/pause. Arrows: step through time. Shift + arrows: larger steps.
