Newspaper archive helps enrich UK landslide database

by Faith Taylor

“The past is the key to the future” – and so creating accurate and thorough records of past events is a common goal for many working in natural hazards. Recording the recent history of some natural hazards is relatively straightforward where automatic instrumentation can be widely used – e.g., using a network of seismometers to record earthquakes across the world. Yet, recording when and where landslides have occurred is a bit of a pain…

The mess of rocks, mud, water and debris left behind on the ground in a landslide is the outcome of a set of processes (e.g., rainfall, ground shaking, erosion). So, to find a landslide, one must actively search for it across a landscape – e.g., by traipsing about in the field, or searching through aerial imagery. It can take teams of geomorphologists literally years of work to create a thorough inventory of landslides from aerial images.

Old newspapers contain a wealth of information on the location of landslides and their impact on communities.

One common way to supplement records of landslides is to use human records, such as newspapers, photographs and diaries. Two excellent examples are (i) Dave Petley’s global fatal landslide database, which uses online news to record deaths caused by landslides, and (ii) the Italian AVI project has records of landslides going back hundreds of years from newspapers.

Yet when searching the literature, we noticed two things – firstly, people aren’t doing this for Great Britain and secondly, people weren’t really talking about how they searched the newspaper archives. I was lucky enough to receive a NERC-EPSRC internship to work with the British Geological Survey on searching the Nexis UK Digital Archive of regional newspapers to try and find articles about landslides.

The first step was experimenting to create a systematic search strategy to be sure that we were picking up as many articles about landslides, and as few articles about things like “landslide victories” as possible. Once this was settled, I applied our search to the Nexis UK archive (thank goodness this is digital and I didn’t have to flick through dusty old newspapers!) and started reading through the thousands of articles returned.

When I found an article about a landslide, I would try to extract as much information as possible, such as the timing, location, size and impact. I would then compare this to what was already in the BGS National Landslide Database to see if we were adding in more detail. To our surprise, this method was really effective and we increased the number of records in the database between 40% – 122% depending on the year examined. These additional records help us to better understand when, where and why landslides occur in Great Britain, and what kinds of impact they can cause.
