Today, one day after #VolcanoThursday some stairs made of #basalt columns ๐พ Our humans found them during #hedgewatch in #Iceland ๐ป These patterns formed during the cooling of #basaltic #lava

Today is #VolcanoThursday ๐ป๐ Last time in #Iceland we couldn't reach the summit of #Hekla due to #Icelandic #weather conditions. So we went to the @LavaCentre and took a virtual tour

Today is #VolcanoThursday ๐ป, but today it's about this wonderful #flower that we found during #hedgewatch on #Tenerife. It's a #Canarina canariensis. This beautiful flower is pollinated by a #bird ๐ the #Canary Islands #chiffchaff ๐ปPawsome๐พ

Today is #VolcanoThursday ๐ป During #hedgewatch on #Tenerife I found this #lava piece with bubbles. #Magma contains gas & when it travels to the surface it cools down & pressure drops so the gas is released & makes bubbles.

Today is the 1st #VolcanoThursday of 2025. This is the #Orotava #valley on #Tenerife formed by a gigantic #landslide. The island was growing so fast that its flanks became unstable & collapsed. At least 500 km3 #rock's moved down causing a #tsunami

This #VolcanoThursday is the 61th birthday of Surtsey a #volcanic island 30km S of #Iceland. It's named after Surtr a fire giant in northern mythology. The eruption ended June 1967. Only scientists are allowed to #hedgewatch there

I am very curious about you're plans for #VolcanoThursday
Sampling altered rocks at >3500 m! Weโre looking at the rocks instead of the incredible view from the top of Teide volcano ๐

Today we are again on #Lanzarote for #VolcanoThursday. This place is called #CiudadEstratificada-#StratifiedCity. Its a bizzare #landscape purrfect for #hedgewatch & made of layers of #volcanic ash. The layers #weathering resistance is varying - thus the shapes.

Today is #VolcanoThursday & the picture is again from the #volcanic island #Lanzarote. Can you see the semicircles made of #rocks? Each hosts a #grapevine. Here a layer of volcanic ash collects can store humidity& protects the plants from the wind.
Prost Cheers

Today is #VolcanoThursday & I show you again a picture from #Lanzarote. During exhausting #hedgewatch my humans saw this. In the front a #VolcanicBomb, in the rigth a stack of #lava flows & in the far distance many #volcanoes

Today is #InternationalCatDay & #VolcanoThursday. Challenge accepted. On figure 1 a famous resident having an eye on the tourists. On figure 2 columnar joints made of #basaltic #rock. Before I forget the pictures were taken during #hedgewatch on #LaGraciosa (Fig3) N of #Lanzarote
Today is #VolcanoThursday some years ago my humans were on #hedgewatch on #Lanzarote & walked a #geology themed #hiking path in the #Parque natural de los #Volcanes. They found this #VolcanicBomb. Because its a park my humans did Not take it home as a #souvenir

Today is #VolcanoThursday. These are #lapilli in #buildingstone. Lapilli describes the size of #tephra-a #volcanic #rock. These are accretionary lapilli-round particles formed in a wet cloud of volcanic ash. Found during #hedgewatch on the #Azores

Today is #VolcanoThursday & I show you a picture taking during #hedgewatch/#hike on the island #LaPalma. View is to the S along the volcanic #CumbreVieja ridge. Each peak is a #volcano. On the horizon you see the #island #ElHierro๐ป

Today is #VolcanoThursday. Several years back my humans visited #geology friends in Gรถttingen. There you you can see #volcanoes on the the western shoulder of the #Leinegraben. Some aren't much older than 10-12mill years. Can you spot the #volcano shaped mountain(s)
Today is #VolcanoThursday & we looked at the pictures from our #GranCanaria #travel/#hedgewatch. On both pictures you see #RoqueNublo (#Rock on the clouds). It's the remnant of an #volcanic conduit & we all know on volcanic soil the best grape vines grow ๐ฝ

Today is #VolcanoThursday. In the #Eifel, a #volcanic region in #Germany, they collect #volcanic #CO2. CO2 is needed for sizzling drinks, welding, in #food production & for the #freezdried supaw treats I get from @RosieandRollo

Today is #VolcanoThursday & this is the #saline #Salinas de #Fuencaliente. We visited it on #LaPalma during #hedgewatch. In 2021 the #eruption of the #Tajogaite #volcano 18 km away ruined large parts of the "harvest" due to its ash. In Decembre the volcano was still smoking
Today is #FossilFriday & yesterday was #VolcanoThursday. During #hedgewatch on #Fuerteventura my humans saw this red stripe between 2 #lava flows. Its #paleosoil that was #fried by the upper flow some mill a ago. Ironoxid is often red & iron can be found in basalt
#geology
Today is #VolcanoThursday. During #hedgewatch in #Fuerteventura's S my humans found many of this "walls". Those are #magma filled fractures that can feed #volcanic #eruptions & here act also as barrier for #groundwater. On the side facing the mountain is more #vegwtation
