The Bulgars, at least the Danubian Bulgars, had a well-developed clan and military administrative system of "inner" and "outer" tribes, [112] governed by the ruling clan. [113] They had many titles, and according to Steven Runciman the distinction between titles which represented offices and mere ornamental dignities was somewhat vague. [ 114 ]

The early Bulgars were a warlike people and war was part of their everyday life, with every adult Bulgar obliged to fight. The early Bulgars were exclusively horsemen: in their culture, the horse was considered a sacred animal and received special care. The supreme commander was the khan, who mustered the army with the help of the aristocracy.
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

The moment magnitude scale – Mw or M w – developed by seismologists Thomas C. Hanks and Hiroo Kanamori, [47] is based on an earthquake's seismic moment, M 0, a measure of how much work an earthquake does in sliding one patch of rock past another patch of rock. [48]
The thematic armies also vanquished many other foes including the Bulgars, Avars, Slavs and Varangians, some of whom eventually ended up in the service of Constantinople as allies or mercenaries. In addition to the themes, there was also the central imperial army stationed in and near Constantinople called the Tagmata .
