Anziehungskraft

Bildinfo

• Anziehungskraft kann man messen: das Gerät im Vordergrund steht in einer Vulkanregion auf Hawaii: füllen sich im Untergrund bisher leere Ritzen, Spalten und kleine Kammern mit Magma, erhöht sich die Anziehungskraft aufgrund des eingedrungenen Magmas. Das Gravimeter rechts im Vordergrund kann selbst kleinste Änderungen noch wahrnehmen und anzeigen.
  

• Originalbeschriftung: A gravimeter measuring the force of gravity on Mauna Kea. These measurements are used to calibrate the instruments so they can precisely monitor changes in gravity from magma accumulation at Mauna Loa (background).

• Since the 1970s, small changes in time-varying gravity (microgravity) have been measured on the active volcanoes Mauna Loa and Kīlauea to determine whether magma is accumulating in their magma reservoirs. This intruding magma often opens and fills cracks and/or empty spaces, causing a net increase in the volcano’s mass that can be measured with a gravimeter. Measuring the gravity is an independent way to confirm whether ongoing uplift, like that occurring at Mauna Loa since 2014, is from new magma intruding into the volcano.
