A volcano erupting in Indonesia is not something that would normally cause too great a flurry, so what is the hype with Gunung Agung? Naturally, people remember well its last eruption which lasted almost a year, was very explosive and, sadly, claimed ~2000 lives. Additionally, this time after official reports about unrest began, there were Continue Reading
The now beautiful Holzmaar erupted 25 000 years ago. Sediment drill cores from here are used in comparative studies in both the Greenland Ice Sheet and Ice Core projects. (Photo: geopark-vulkaneifel.de)
A maar is a hole in the ground, of volcanic origin… what else?… caused by interaction with water… That was about all I knew about maars when I prepared for this year’s holiday, in the German Eifel maars area (Vulkaneifel, Rheinland-Pfalz district). I did not expect to find a great lot of evidence for former volcanic activity. Probably all covered by sediments or eroded, mined away or grown over – that’s what I thought.

I hope everyone had a great Christmas time and got at least one volcano book for present. Now I wish you all a Happy and Healthy New Year with lots of time for reading your new book and other volcano stuff as, for example, the Volcano Hotspot blog 😉 – Lately, Bogoslof volcano has been doing great things, and while we wait for agimarc to come up with a treat for us on that volcano, lets have a look back to the year 1951.

This is hardly a place the average tourist would choose to use his saved up money and spare time to spend an extended holiday, and yet, it’s the place where many a scientist of any calling would gladly give an arm and a leg to be able to go for an extended research project. Continue Reading
