When Chile was hit by a magnitude 8.3 earthquake this week, the very ground shifted. By comparing images before and after the earthquake with an interferogram, geophysicists can measure just how much and where the ground moved. An interferogram is a geophysical tool for tracking changes in surface topography over time. It can be used to find landslides, or to spot when a magma chamber is filling and forcing a volcano to bulge out prior to an eruption. It can track subsidence when groundwater is being over-pumped or a river delta is sinking, or to watch the incredibly slow flow of glaciers. John the revelator saw into the future when earthquakes would become so powerful that it would actually move and shift islands and Mountains!
Revelation 6:12-14 I looked when He opened the sixth seal, and behold, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. 13 And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind. 14 Then the sky receded as a scroll when it is rolled up, and every mountain and island was moved out of its place.
Isaiah 24:20 – The earth shall reel to and fro like a drunkard, And shall totter like a hut; Its transgression shall be heavy upon it, And it will fall, and not rise again.
But possibly most dramatically, interferograms can be used to spot just how much an earthquake tore the ground in a burst of energy, shifting the very earth in a few seconds of severe shaking.Interferograms are created by visualizing the interference pattern between two synthetic aperture radar (SAR) passes. When radar images of the same location at the same angle and distance are taken at different times, we create an image of the interference between the radio waves to very precisely measure changes in the intervening time. This particular interferogram was created using data from the ESA Sentinel 1 satellite taken on August 24 and September 17, 2015, capturing displacement from the earthquake on September 16th.
