I like this view taken from Mauna Kea summit. Mauna Loa is in the background with the eruptive volcanic plume. From the plume ash and gazes spread horizontally in the high atmosphere.

My former PhD student Gino De Gelder has published a beautiful paper on the famed #Huon peninsula, in New Guinea, where Chappell and Shackleton have defined one of the first #Quaternary #eustatic curves ~40 years ago.

Worth reading if you are interested in marine terraces, #geomorphology, sea level variations, #eustasy, #landscape modelling, tectonic uplift, Quaternary #climatechange…

On bad Friday we have refurbished our two iphones for 150€ (2 batteries, 1 screen), thus avoiding wastage. Remember not to renew electronic devices before 5-7 years of use. #sufficiency

While the famous #keeling curve record of atmospheric #CO2 is currently interrupted because of #MaunaLoa eruption, listen how Scientists Measure Carbon Dioxide in the Air.

In the linked video, #Scripps scientist Ralph Keeling, the son of Charles David Keeling who started to develop the CO2 measurement at Mauna Loa observatory, explains how the measurement is done. The keeling curve is named from C.D. Keeling.

Amazing #USGS aerial view of the eruption on the northern flank of #MaunaLoa #volcano in #Hawaii. The main erupting fissure shows its high lava fountains in bright yellow. From there anastomosing rivers of fresh lava flow downslope and to the north. Crest and summit of Mauna Kea in the back.

Because of the #MaunaLoa eruption and lava flows, the #CO2 measurement equipment that maintains the famous #Keeling Curve lost power on Nov. 28 and is not currently recording data.

Citing their post: "The Keeling Curve is considered the icon of scientific evidence that human activities are altering the planet’s #climate. It has provided incontrovertible evidence that the amount of [atmospheric] gas carbon dioxide has risen far above any levels experienced on Earth for at least three million years […] Researchers at #Scripps Institution of Oceanography, which established the Keeling Curve record at the site in 1958, are exploring options regarding the relocation of measurement equipment."

Updated #USGS map of #MaunaLoa eruption and lava flows. Lava flows already cut the road to NOAA observatory.

Correction: as @culturevolcan pointed out, this is NOT the northeastern rift zone, but the southwestern volcano flank.

Citing: "This picture shows in fact a portion of the initial eruptive fracture cutting the upper South-West flank. Mostly gaz release a a few short lava flows there berfore the magma was drained by the North-East Rift Zone"

Looking carefully to the background you may see the South Pit and two small rounded volcanoes that are located SW of the main caldera.

Another excellent view of the #MaunaLoa upper northeastern rift zone with the active erupting fissure in the foreground. The summit caldera is in the back.

On this image 👇🏼 , the erupting fissure with lava fountains is visible to the upper left. From the fissure reddish lava flows downslope.
