So every year I say I should do more blogging…we will see how that goes. But in the mean time, I asked Twitter for some ideas of what to write and got this suggestion from my friend and fellow PhD volcanologist Geoff Lerner (he is doing some awesome stuff out in New Zealand, do check out his Twitter!)
So using inspiration from Geoff…I’m going to attempt to give a general overview of how historical volcanology works.
To begin: how did we come to know about the 79 AD eruption of Vesuvius, and the destruction of Pomepii and Herculeum? The observations of Pliny the Younger. He was a man who lived in the distant past who observed a volcanic eruption. We also have countless volcanology studies about the eruption (and others that happened since). We also have unearthed archaeological sites and artefacts. Thanks to all this evidence, we now know that this eruption happened and its impacts on the surrounding society.
A historian is a person who researches past events that relate to humans through narratives. Volcanologist one way or the other look at past volcanic eruptions…so you could say we are “Earth” historians.
Volcanology in itself is diverse and researchers come from all different backgrounds: geology, petrology, geophysics, engineering, geochemistry – I labelled here a number of “physical” science disciplines. In volcanology we are increasingly seeing the inclusion of the “social” sciences when exploring the impacts of volcanism on an exposed population.
Historians use tangible (sites, objects, instruments, remains) and intangible (memories, narratives, indigenous knowledge) artefacts. So a historical volcanologist uses tangible and/or intangible artefacts to understand past volcanic events from the human perspective. For me, I have mainly used intangible artefacts, with written records in archives and interviewing people remembering an eruption. Archaeologists are particularly good at using tangible artefacts, with plenty of research out there of looking at deep past volcanic events and their impacts on early human civiliations.
If a volcanologist looks at past volcanic events, combining the understanding of how people responded to the event within the historical and social context, with the scientific understanding of volcanism, it provides a richness and numerous perspectives of the story of an eruption that may not have been captured if doing a single disciplinary approach. Looking at the past, we can see how much the volcano and the society that live around it, have changed or not. Further social volcanology studies for a given volcano would benefit from the historical perspective in this way. Furthermore, a “traditional” physical volcanology study would complement a historical volcanology study and vice versa. One or the other could find things the other had not found before, which could lead to a fuller picture of what happened!
So to end this post I have compiled a little checklist I have gained during my PhD doing a historical volcanology project:
- Whatever “physical” science approach to volcanology you use, think outside of the box of how it would be beneficial to the society who has to live with the particular volcanic region you are researching;
2. This is important for every volcanologist – do your research on your volcano: its past activity, current activity, what signs and hazards it is known to produce and any probablitic scenarios of any potential future impact on society;
3. And now we take it up a notch: do your homework on your volcano in the context of the society who had to live with it. Here I mean the social and cultural significance of the volcano, what they knew and do not know about it, and perhaps most importantly (if using intangible artefacts): what language was used to describe what they saw and felt about the volcano? In times of activity would be a priority, but if you have the time (and money) look at quiet periods too;
4. And now, if you are looking at a historical eruption and you want to see what is in the archives* ask yourself: has the language to describe any volcanic phenomena associated with the volcano, similar or different to the present? You will need to be very aware that in the past, especially before the modern notions of “volcanology” as a science, people were very descriptive when observing volcanic activity (think “curtains of fire”, “it grew dark during the day”, “we heard rumblings” and so on);
*Using archives first requires identifying a collection: in most places this is available online, others it requires contacting the specific department and arranging a visit to see what is there. If a collection may prove useful, be prepared to go down some rabbit holes and not come back up for a while…it takes perseverance to find what you are looking for.
5. Be respectful of the words written/spoken, objects etc. of those who are no longer here. As a volcanologist, and as a scientist, you can interpret what was observed with rigour but never dismiss other people’s own interpretations when they were within the moment, observing a phenomena they may have never witnessed before. Like all disasters, volcanic eruptions induce stress and anxiety (usually temporarily, but sometimes longer), occurring in their own social and cultural context that is different from your own;
6. Be extra mindful when researching volcanoes in countries that were colonised/occupied. I say this because written records that have survived are usually of one dominant “voice” and many others have either been manipulated or silenced. For my investigations into the 1812 and 1902-1903 eruptions of La Soufrière, I found that the voices of women, children, African slaves, freed persons of colour and indentured servants were almost entirely absent or manipulated (the experiences of myself, my family and POC friends allowed me to have a trained eye to stereotypical/racist language and behaviour). I tried to correct this by doing my interviews for the 1979 eruption by including men and women of varying ages and ethnicities – remember: each voice who provided a narrative is valid as many people experienced these violent events with their own education, experiences and perceptions;
7. Seek out local historians, they may know information that you could not find. I have been in contact with a local Vincentian historian who has been super helpful in pinpointing locations that no longer exist on maps today – then of course give credit where credit is due;
8. Lastly, give back! I have used documents from multiple archives in 3 different countries, all have had a dedicated curator/librarian to help me find what I needed and are super keen to help in anyway possible. As a way of saying thanks and to provide knowledge for any future researcher, give a copy of your finished work to the archive you used. For public dissimination, certainly put the country whose volcano you are researching first – you may be as creative and collaborative as you like!
Historical volcanology has been a new and exciting avenue to me, I have learned a lot about the volcano, the country, its people and myself. I know people say “leave the past in the past” but how else would we know how to better ourselves as a people and know how far we have come in living on this dynamic planet?
To embrace the future…why not start with the past!
