Our paper on the #tectonics of this very remote area 👇🏼 in the #Atacama #desert is finally accepted for publication in EGU Solid Earth (will be Habel et al. 2022).

I'll say more when the article is online 😉

On 4 December, at 15:19 UTC, a strong #pyroclastic flow along the Sciara del Fuoco on #Stromboli #volcano reached the sea and generated a moderate #tsunami, hopefully not causing damage (according to INGV). Tide gauge in Ginestra recorded it with a delay of only a few minutes, and crest to crest amplitude of ~60cm.

Stromboli is an Italian very active volcano from the Aeolian islands in the Tyrrhenian sea (Mediterranean). Its activity, and more particularly hazards due to the pyroclastic flows, are monitored by INGV.

INGV reported about the tsunami: https://ingvterremoti.com/2022/12/05/stromboli-4-dicembre-2022-tsunami-si-o-tsunami-no/
And about the volcanic event itself: https://ingvvulcani.com/2022/12/05/cosa-e-successo-a-stromboli-il-4-dicembre-2022/

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."
