  1. Thanks agimarc! That mountain looks menacing enough to be capable of creating all sorts of mischief. I only wonder – with all that hodgepodge of diving under, breaking up, crashing into, creeping over etc. of plates and terranes in that area – why there are not many more volcanoes erupting? Look at the west coasts of central and southern America, there is always something happening in any given country, and there are only 2-3 plates involved.


  2. Thanks for the article agimarc.

    On a different subject I found this video of the present La Réunion eruption from quite close

    • Thank you Kind Sir. We miss you also. Hope all is well with you and yours. Would you consider an after action post on Calbuco (assuming you get a little writing time)? Cheers –


    • Hello Renato, so good to “see” you again! Hope everything goes great for you! Just drop us a line every now and then. Miss you too…


  3. Came across this wonderful video of the last inspection of Sabancaya’s crater. Text below video: “OVS volcanologists, led by its director, Dr. Orlando Macedo, braved 26 last July the crater of Sabancaya, in order to inspect its morphology, obtaining in-situ thermal imaging and identify emission points in the fumaroles near the crater. The entire team of professionals who performed this task consisted of Ing. Victor Aguilar, seismologist at the Geophysical Institute of the UNSA, besides Ing. Jose Torres and Tech. Rolando Chijchepaza, members of the OVS. Similarly The South Volcano Observatory thanks very special professional mountain guide, Caclla Eloy Cardenas, who accompanied the work team of OVS professionals in this important form. Thanks, Eloy.” They say in the video that the thermal images shown were the first ones ever taken of a volcano in Peru. Thanks IGP!

    Besides, a shallow (16 km?) M 5.0 earthquake has happened 6 km SE of Sabancaya just an hour ago. I am not sure if it can be attributed to the volcano as its magma chamber is supposed to lie some 15 km NE of it.


  4. Update on Cotopaxi, from Cotopaxi Special Report No. 12
    Seismic energy has reached and maintained a high level in the last three days. In the August 26 flyby high temperatures were observed in the emission column. Also higher temperatures were found on the flanks, where reduced snow cover allowed measurements. The output of ash and gases (high SO2) is continuous.

    Thermal image of S and SW flank of the volcano where temperatures observed (TMA) are indicated. Right: corresponding visual image with annotations (Click to enlarge. Photo: P. Ramón IG/PN).


    • Thanks for the link, agimarc. It is a hypothesis, we’ll have to wait another ten years for it to become a fact or get dismissed. 🙂 To my humble mind it sounds a bit unlikely from the abstract, one needs to read it all, though. Do yyou have access to the full pdf?


  5. Volcan Fuego (Guatemala) is in constant strong eruption since at least yesterday, with lava flowing down several sides of it. I hope people are allright…

    Greg Waite is keeping a YT video channel with daily time lapses from the webcam, overlaid with the seismogram line, and the sound track of the specktrogram beside it. It will be worth watching the one from last night later on.

    Does anybody have a link to latest reports on Fuego, I can’t find them on the INSIVUMEH website?
