Old Map of US Tornado Activity 1930-1974 by Fujita & Pearson: Paths, Death Statistics, Tornado Alley

This remarkable thematic map, titled "U.S. tornadoes, 1930-74," offers a visually arresting chronicle of nearly half a century of tornado activity across the contiguous United States. Created in 1974 by the eminent meteorologists T. Theodore Fujita and Allen D. Pearson, the map presents the paths of 19,189 tornadoes, weaving a dense and intricate tapestry of meteorological history. The main focus is the frequency, distribution, and human impact of tornadoes, making this map not only a cartographic achievement but also a profound statement on the intersection of natural forces and human lives.

At the heart of this map lies a masterful use of infographic techniques. Each tornado path is meticulously traced, resulting in a dramatic concentration of lines that immediately draws the eye to the infamous "Tornado Alley" of the central United States. The map’s design elegantly balances clarity and density, using subtle background features such as state boundaries, major rivers, and the Great Lakes to provide orientation without distracting from the central data. This approach reflects the best traditions of 1970s scientific cartography, where function and form are harmoniously intertwined.

What truly elevates this map is its integration of statistical insets, which chart tornado-related fatalities by decade from 1930 through 1974. These five inset maps provide a sobering counterpoint to the swirling tornado paths, contextualizing the human cost of these natural disasters. The inclusion of these infographics transforms the map from a mere record of meteorological events into a nuanced exploration of risk, resilience, and the evolution of public safety in the face of nature’s unpredictability.

The map’s creators, T. Theodore Fujita and Allen D. Pearson, are legendary figures in the field of severe weather research. Fujita, in particular, is renowned for developing the Fujita scale, which remains a foundational tool for assessing tornado intensity. Their collaboration on this map not only lends it scientific authority but also marks a pivotal moment in the history of meteorology, as researchers began to harness visual data to communicate complex patterns and drive public understanding.

Beyond its immediate scientific value, this map stands as a cultural and historical artifact. It captures a period of transformation in American meteorology, when advances in data collection and analysis began to yield new insights into the patterns of extreme weather. For collectors, historians, and weather enthusiasts alike, this map offers both a snapshot of a defining era and a testament to the enduring power of cartography to illuminate the forces that shape our world.

This map is available as a giclée print on acid free archival matte paper, or you can buy it framed. The frame is a nice, simple black frame that suits most aesthetics. Please get in touch if you'd like a different frame colour or material. My frames are glazed with super-clear museum-grade acrylic (perspex/acrylite), which is significantly less reflective than glass, safer, and will always arrive in perfect condition.

This map is also available as a float framed canvas, sometimes known as a shadow gap framed canvas or canvas floater. The map is printed on artist's cotton canvas and then stretched over a handmade box frame. We then "float" the canvas inside a wooden frame, which is available in a range of colours (black, dark brown, oak, antique gold and white). This is a wonderful way to present a map without glazing in front. See some examples of float framed canvas maps and explore the differences between my different finishes.

For something truly unique, this map is also available in "Unique 3D", our trademarked process that dramatically transforms the map so that it has a wonderful sense of depth. We combine the original map with detailed topography and elevation data, so that mountains and the terrain really "pop". For more info and examples of 3D maps, check my Unique 3D page.

For most orders, delivery time is about 3 working days. Personalised and customised products take longer, as I have to do the personalisation and send it to you for approval, which usually takes 1 or 2 days.

Please note that very large framed orders usually take longer to make and deliver.

My standard frame is a gallery style black ash hardwood frame. It is simple and quite modern looking. My standard frame is around 20mm (0.8in) wide.

I use super-clear acrylic (perspex/acrylite) for the frame glass. It's lighter and safer than glass - and it looks better, as the reflectivity is lower.

Six standard frame colours are available for free (black, dark brown, dark grey, oak, white and antique gold). Custom framing and mounting/matting is available if you're looking for something else.

Most maps, art and illustrations are also available as a framed canvas. We use matte (not shiny) cotton canvas, stretch it over a sustainably sourced box wood frame, and then 'float' the piece within a wood frame. The end result is quite beautiful, and there's no glazing to get in the way.

All frames are provided "ready to hang", with either a string or brackets on the back. Very large frames will have heavy duty hanging plates and/or a mounting baton. If you have any questions, please get in touch.

See some examples of my framed maps and framed canvas maps.

Alternatively, I can also supply old maps and artwork on canvas, foam board, cotton rag and other materials.

If you want to frame your map or artwork yourself, please read my size guide first.

My maps are extremely high quality reproductions of original maps.

I source original, rare maps from libraries, auction houses and private collections around the world, restore them at my London workshop, and then use specialist giclée inks and printers to create beautiful maps that look even better than the original.

My maps are printed on acid-free archival matte (not glossy) paper that feels very high quality and almost like card. In technical terms the paper weight/thickness is 10mil/200gsm. It's perfect for framing.

I print with Epson ultrachrome giclée UV fade resistant pigment inks - some of the best inks you can find.

I can also make maps on canvas, cotton rag and other exotic materials.

Map ageing

I have been asked hundreds of times over the years by customers if they could buy a map that looks even older.

Well, now you can, by selecting Aged before you add a map to your basket.

All the product photos you see on this page show the map in its Original form. This is what the map looks like today.

If you select Aged, I will age your map by hand, using a special and unique process developed through years of studying old maps, talking to researchers to understand the chemistry of aging paper, and of course... lots of practice!

If you're unsure, stick to the Original colour of the map. If you want something a bit darker and older looking, go for Aged.
