Field Research in Guatemala (5) – Photo Diary

After 2 months based in Guatemala undertaking hazards research, I am soon to return home. I will be continuing this series of posts over the next few months, reflecting on aspects of conducting research overseas and thinking through results. Guatemala is a stunningly beautiful country, with a dynamism reflected in everything from the landscapes to the markets. Everybody I have met has been incredibly kind and generous with their time, always willing to share their experience and knowledge.  Today I share a selection of photographs from the my time here…

Friday Photo (119) – Pacaya Lava Store, Guatemala

Lava Store, Pacaya Volcano, Guatemala

An entrepreneurial Guatemalan sets up a lava store next to Pacaya (my understanding is that they sold products made from the lava, not just pieces of it – which are in abundance in the area!). This store was destroyed by the 2nd March 2014 lava flow.

Field Research in Guatemala (4) – Reflections from Fuego

Joel Gill (GfGD Founding Director) continues his live reporting from Guatemala, discussing his interdisciplinary field research relating to natural hazard interactions and disaster risk reduction. This fieldwork forms part of a NERC/ESRC funded PhD, supervised by staff in the Department of Geography at King’s College London.

Over the past few weeks I’ve had the opportunity to see some remarkable things in Guatemala. The most special but also poignant time was around the Volcano Fuego. This location rapidly became my favourite in Guatemala, and for a number of a reasons a place I can’t get out of mind. In today’s post I reflect on some personal feelings – touching on both the incredible beauty of volcanic activity but also the serious danger that these phenomena can cause to vulnerable communities, and our responsibility to support disaster risk reduction.

Let me set the scene, we get up and set of at around 7.30am – driving for a couple of hours around and then up the side of a volcano, Acatenango. After parking up, we put our backpacks on, admire the stunning view across the plain of the volcano Agua and set off on a long walk. This trek takes us around the side of Acatenango so as to get a view of the active volcano, Fuego.

When the volcano came into sight, we were greeted with a loud explosion of noise and the firing of material (mainly gas, ash and rock material) into the air. This was my first sight or experience of an erupting volcano. It was relatively gentle activity, these blasts normally occur at Fuego several times each day at the moment. Shortly afterwards the volcano grumbled again and more material was ejected into the air. This happened a third, fourth, fifth time… and more. Seeing something so close, and hearing the intensity of the bang and the amount of material ejected – and yet also appreciating how small the eruption was compared to the kinds of eruptions that demand mass evacuations was quite poignant. During a serious eruption, the noise and volume of material must be phenomenally scary to encounter.

Volcanoes are remarkably beautiful by day, but at night they are simply stunning. Arriving at the Fuego Volcanic Observatory I was designated an open air bed in the back of a pick-up truck. This turned out to be the best bad night’s sleep I’ve ever had. My view for the night would be Fuego. The observatory is located on the other side of the volcano to the views we’d got by day. Once dark, and with a clear night, each explosion sent out of the volcano a blast of red-hot rock, as well as gas and ash. The peak of the volcanic cone glowed red as very hot ‘volcanic bombs’ fired into the air and rolled down the volcano at tremendous velocities. These small eruptions elicited genuine awe and amazement… it was a truly unforgettable evening.

Seeing these sights was an incredible privilege as a geologist, a hazards researcher or just as someone with a love of the natural environment. But the chance to see these things also comes with a stark reminder that I almost certainly won’t be next to the volcano when it next explodes with the huge power that may kill many people. This was hammered home the following day, when we visited sites of recent lahars and pyroclastic flows – two hazards associated with this volcano.

Lahars are generated when rain mixes with sediment created by the volcanic eruptions. They move with great speed and power, carrying huge amounts of material with them. In 2012, after a larger eruption of Fuego, a number of lahars were generated in the rainy season carrying with them material that had formed a pyroclastic flow down the volcano. These lahars impacted an area with little previous experience of lahars, and destroyed a crucial road in the process. The loss of this road now means that communities are isolated from their villages – making evacuation in the event of a large eruption very difficult. The lahar deposits include a range of particle sizes, from fine sediment to huge boulders. As such driving across them is far from straightforward.

Lahars themselves are very dangerous, and have been responsible for major fatalities around the world in the past. They also trigger further hazards (e.g. flooding) downstream. In this location, they have significantly increased the vulnerability of an already vulnerable community. When the next large eruption takes place, people will need to evacuate. Many won’t and many won’t be able to. Those who try are going to face the additional significant difficulty of trying to cross lahar material. If this was in the middle of rainy season, any attempt to do so would almost certainly be impossible or perhaps fatal. People could try finding another route, but in a large vulcanian eruption the volume of ash means it can be very difficult to see more than 1-2m in front of you. Attempts to evacuate by routes other than those closest would be difficult. In one other location around this volcano, evacuation is only possible via a narrow rope bridge.

Seeing this location, and talking to people about it during my research interviews afterwards, was really sad. Seeing the genuine desire of people to help, a real heart-felt concern – but an inability to do anything due to an all too common problem of lack of funding. More bridges, evacuation routes and shelters can’t be built as they cost money. Even if those were in place, poverty means some people may choose not to leave as they don’t want to risk losing their property or assets. Others can’t leave due to disability, illness or age.

I feel incredibly privileged to have seen Fuego by day and night, climbed close to its summit and marvelled at one of nature’s most beautiful sights. I also feel a huge weight of responsibility and a strong desire to utilise the skills, the knowledge, the contacts, the resources that I have available to address some of the injustices that currently mean that a large future eruption of Fuego could result in a significant disaster event – education, an ability to evacuate safely and rapidly, a reduction in poverty, access to insurance schemes that will help people feel safer leaving their property, better monitoring equipment for the volcanic observers.

When I leave Guatemala on the morning of the 17th March I’ll be leaving with the communities around Fuego in my mind and a determination to use those resources available to me to serve them through strengthening disaster risk reduction.
