A team of geologists from the Museum and Imperial College are in Mexico carrying out  fieldwork at two of the most active volcanoes in the world: Popocatépetl (Popo) and Colima. Catch up with their adventures in this series of blogposts.

 

Three weeks of amazing fieldwork at two of the most active volcanoes of the world have come to an end: Popocatépetl and Colima, you have been very generous to us, both in terms of large quantities of promising samples and impressive levels of activity. Now that we are back in London, we want to conclude this blog for the time being with some take-home impressions of our beautiful Mexican volcanoes.

 

As scenic and contemplative these pictures may be, all the steam puff, ash clouds and fresh lava streams are a constant reminder of the immense destructive powers slumbering within these giant volcanoes, posing imminent danger to its surroundings. Both Popo and Colima have shown increasing levels of activity in the last months, making detailed real-time monitoring as well as fundamental studies of the underlying principles of the volcanoes’ dynamics even more pressing and important.

 

Using the samples we collected during the last three weeks, we, at the Natural History Museum and Imperial College will work hard in the future to contribute to the understanding of how Popo and Colima work.

 

There is more fieldwork at Popo to come in the next years, and of course we will be covering these trips at this exact place again. Until then, enjoy the pictures and be sure to watch out for a forthcoming NatureLive event at the Museum’s Attenborough Studio, where we will be talking in detail about our exciting trip to Popo and Colima! Thanks for reading.

A last view from our hotel in Amecameca: Popo bids farewell to us with a nice trail of steam puffs.

The danger within the clouds: Fuego de Colima. Even through the cloud cover, one can make out the gases that are constantly exhaled from the summit.

The black lava flow in the center of this image has been emplaced during the last two years of activity of Fuego de Colima. The ‘clouds’ you can see here are actually gases coming from this lava flow, which is still hot.

We arrived on Tuesday, set up what will be our home for the week, with a stream babbling under.

 

We spent today visiting fossil shops and talking to the owners to see what was on offer and meet the collectors. We then went to the Lyme Regis Museum to talk to our colleagues there about new specimens and the local geology. Whilst there Emma had some fun dressing up as Mary Anning, the 'Princess of Palaeontology'.

In the afternoon (after an ice cream by the sea) we set off for Seatown where we learnt about the geology and did a little fieldwork. The geology is the upper Lower Lias (about 185 Million years ago) - it is a marine setting with lots of belemnites and ammonites.

 

We found lots of bits of belemnite, but the highlight was definitely finding a phragmocone of a belemnite; the cone-shaped structure that housed the creature's internal organs. Of the ammonites, Aegeroceras was the most common find. However we did find part of an Amaltheus (My favourite Jurassic ammonite because of its rope-like keel).

Tomorrow we are heading off to a secondary school event in Dorchester to explain the wonders of cephalopod taxonomy. Now we are heading off to grab some well earned dinner! Come back to read more about our adventure!
