Geophysical, geological, and petrological observations with high temporal resolution largely contribute to real-time understanding of the mechanism of volcanic eruptions and eruption forecasting. Recent advances in geophysical monitoring methods (tiltmeter, strainmeter, GNSS, and SAR) enable us to obtain information on pressure changes in magma chambers and magma properties from volcanoes with ongoing eruptions by coupling the geophysical data with physical models of magma chamber and conduit flow dynamics. Geological observations such as magma flow rate and volume, and petrological analyses on eruptive materials sampled with high temporal resolution also make substantial roles in understanding magma chamber and volcanic conduit conditions and predicting eruption sequence. This session aims to gather geophysical, geological, and petrological insights and discuss how we can better understand the eruption mechanism in real time and forecast eruption sequence.
