Were some ancient buildings partly designed to withstand massive blasts from natural catastrophic events or even Electric Universe events?
Brian Cairns in his Thunderblog Neolithic Man and the Electric Universe explains this idea in relation to structures in Sardinia in the Mediterranean.
Exploring this intriguing idea - the ancient megalithic builders or population of the Islands of Malta and Gozo, also in the Mediterranean, built impressive large free standing stone structures. What are called the Malta Temples have a design that seemed to evolve over time.
Were the Maltese Temples partly designed to take advantage of blast pockets, blast rooms, blast traps to make them more 'blast proof' to natures bombs?
Rock of Gibraltar - tunnel blast pockets
The British owned Rock of Gibraltar has many tunnels engineered into it by the British military. One of the interesting features of these Gibraltar tunnels is that some of the entrance tunnels have blast traps and blast pockets at the very start and at the end of the tunnels.
Blast traps were added to both pedestrian and vehicle entrances. The pedestrian blast traps were relatively simple, consisting of three blast walls overlapping by at least three-quarters of the width of the tunnel. A more elaborate approach had to be adopted for vehicle tunnels, where L-shaped entrances equipped with blast pockets were cut. The blast pockets were intended to absorb and reflect the blast wave, preventing it reaching far inside the tunnel complex. Gas locks were also installed to protect against contamination from the outside.

If memory serves me correctly each blast trap would absorb something like 30% of a blast.
A blast trap was used to protect entrances. This was achieved by having the access to the main communications tunnel turn shortly before entering it so that any blast effect would be absorbed at the end of the tunnel entrance.

Maltese Megalithic Structures
Some of the ancient Maltese people seemed to live in caves, dug underground chambers (they had troglodytes living in Ghar il-Kbir until the 18th century!), catacombs and famously built Hypogeums, large underground 'Temples' or burial place.
The Maltese Temples are mainly thick externally walled structures with rooms to the sides of the main internal hall. They are mostly very thick walled and quiet low, with no surviving roofs. The Tarxien Temples, again with only low height wall design or remains, also has a large statue that with only the bottom half remaining.
If you had blast traps in pairs, on either side, and a couple of these sets then you would really reduce the blasts energy. And have a good structure that you could use in normal times.
