(BIVN) – On March 14, the USGS Hawaiian Volcano Observatory’s webcam captured an image (above) of a double rainbow, which they say “seems to end in Moku‘āweoweo, the caldera at the summit of Mauna Loa.”
“No pots of gold were observed—only patches of snow from recent winter storms,” the scientists wrote as they posted the image to the HVO website, the first photo in the Mauna Loa section of the website to added since December 3, 2017.
Mauna Loa Volcano is not erupting. USGS reported on Thursday that rates of deformation and seismicity have not changed significantly in the past week, persisting at above-long-term background levels.
“Sixteen microearthquakes were located beneath the summit caldera and upper elevations of Mauna Loa during the past week,” Hawaiian Volcano Observatory scientists wrote. “Of these, roughly equal numbers are beneath the summit caldera and upper southwest rift, at depths ranging between 0 and 5km (0 to 3mi), or scattered beneath the upper western flank.”
“Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) measurements continue to show slow deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone,” USGS says. “No significant changes in volcanic gas emissions, sulfur dioxide or carbon dioxide were measured.”
