The Wee-g micro-gravimeter at Poas produces continuous time series of gravity variations at the VPMI station. These can be interpreted as subsurface mass redistributions when corrected for environmental effects such as Earth tides and atmospheric pressure changes.

  <Card title="Gravity Time Series">
    Continuous record of variations in the local gravity field at VPMI.
  </Card>

  <Card title="Mass Change Estimates">
    Interpreted subsurface magma or hydrothermal fluid movements, used alongside GNSS and gas data to constrain volcanic processes.

<Note>
  Gravimetric data from Poas are currently archived at LDEO and are being
  transferred to the University of Glasgow for processing and analysis.
