How Groundwater Extraction & Replenishing Causes Surface Deformation & Subsidence

Standard

Researchers at Caltech made the animations below which show the seasonal deformation and subsidence of Earth’s surface, respectively,  as a result of groundwater extraction and refilling.

Surface deformation and subsidence of Earth’s surface is measured using Interferometric Synthetic Aperture Radar (ISAR). ISAR is also used for natural hazard assessment. This includes applications to regions of volcanic, tectonic (e.g. faults and mountains), and construction activities.

Heisenberg’s Uncertainty Principle by Dr. Walter Lewin

Standard

A reminder of the basics of quantum mechanics.

An atom is all vacuum. You and I are all vacuum. You think of yourself of being something but we are nothing.
