Which countries have the most volcanoes? I am currently learning the programming language Python, mainly to visualise data and draw maps. Since the examples in the tutorials were too boring for me, I have taken on more interesting questions. An interesting dataset is the list of active volcanoes (i.e. at least 1 eruption in the … Continue reading “Volcanoes per Country”

Hike to the green crater lake of the active volcano in Chiapas (Mexico)
In the Tertiary period, many volcanoes were active throughout northern Czechia (and beyond), indirectly related to the mountain building of the Alps: Parts of Europe tried to avoid the thrust of the collision, which was accompanied by stretching roughly in an east-west direction. Throughout Central Europe, rift systems (including Rhone Graben, Upper Rhine Graben, and … Continue reading “Trosky, a volcano in the Bohemian Paradise”

Tracing the latest volcanic eruption in Chile
The lake district with its green fields, dense rainforests, countless lakes of all sizes and towering volcanoes and mountain peaks (cf. The Formation of Mountains) is, so to speak, the southern end of civilisation in South America: a little further on, the sparsely populated wilderness of Patagonia begins. I fly to Puerto Montt and drive … Continue reading “Puerto Varas in the Lake District of Chile”
The GR 131 hiking trail on La Palma combines the Ruta de los Volcanes with the Ruta de la Cresteria for a four-day hike, an island crossing that is scenically and geologically spectacular (Canary Islands, Spain)
The most beautiful way to climb Teide is to traverse Montaña Blanca, Teide and Pico Viejo with an overnight stay at the Refugio de Altavista
It was about time that I paid a visit to the Canary Islands. After all, Teide is the highest hotspot volcano after Hawaii’s and much quicker to reach… However, there are also a few important differences to Hawaii, for example, a stratovolcano like Teide is not exactly typical of a hotspot, nor are the large … Continue reading “Tenerife”

This volcano is situated in the very east of Java. The crater is filled by a greenish sulphuric acid lake. A huge sulphur body has formed near the shore, brown hot sulphuric steam rises hissing.

More than 2 m of pumice was deposited on the first day of the 79 AD eruption of Vesuvius. The weight caused roofs of buildings to collapse, but people died in the pyroclastic flows (surges) that came down the mountain towards the end of the eruption. A caldera formed during the eruption, and Mt. Somma … Continue reading “Excursion: Volcanism Southern Italy”
