The Tambora caldera formed during the 1815 eruption, after 41 km³ of magma (dense rock equivalent) was expelled, leaving the 6-km-wide and 1-km-deep depression seen in this July 2019 Planet Labs satellite image mosaic (N is to the top). The current area of the caldera is approximately 34.5 km², with erosion altering the surface and remobilizing material onto the caldera floor.
