![]() Source: Hawaiian Volcano Observatory volcano activity update 14 October 2023įaint glow in the ponded area suggests a crystallization phase of lava (image: HVO)The lava supply onto the Halemaʻumaʻu lava lake has ceased. Despite this elevated unrest, there is currently no indication of an imminent eruption in the region. Scientists concluded that the current elevated seismicity and inflation may represent a magma injection to the Southwest Rift connector and might eventually rise further upward to the surface. Over the past 24 hours, the seismic activity has significantly decreased. The largest event so far was recorded with magnitude M 2.8. There have been about 1200 earthquakes since 4 October, mostly at depths between 1-5 km with magnitudes smaller than M 1. The SWR connector is considered to be a feeder pipe for magma into the Southwest Rift Zone. Moreover, an elevated seismic activity has continued over the past week, propagating in the southwest linear area along the Southwest Rift connector. ![]() Inflation of the ground surface in volcanic areas results from stress changes in the crust due to the accumulation of magma or the exsolution of gas inside reservoirs or due to the propagation of magma through intrusions or conduits. ![]() Tiltmeters and GPS stations indicate that most of the deformation occurred since the beginning of October with lower rates over the past day. The attached map shows coloured fringes representing 1.5 cm (0.6 in) of the ground inflation of each colour cycle. Colored fringes denote areas of ground deformation and yellow circles denote earthquake locations (image: HVO)Ī new InSAR (Interferometric Synthetic Aperture Radar) sensing revealed a ground uplift beneath the southwestern area of the volcano from 24 Sept-10 Oct, the Hawaiian Volcano Observatory (HVO) reported. ![]()
