In this particular case that may not be true, but only because of Burma's particular geology.
The Sagaing fault in Burma is a major straight 1200 km "strike-slip fault" very similar to the famous (1200 km) San Andreas fault in California. But unlike the San Andreas fault, the Sagaing fault is known to produce cascading major earthquakes, one after another, spaced a year or so apart. One might guess this could happen after a long quiet period, just like before now:
It's history of M7+ earthquakes (1906 M7.0, 1912 M7.5, 1929 M7.0, 1930 M7.2, 1930 M7.3, 1931 M7.6, 1946 M7.7, 1956 M7.1, quiet) !
Worse, yesterday's quake only partially ruptured a segment of the fault that 'should/could have' ruptured but didn't. Oops. For more detail below are two similar historical lists, differing only in fine criteria, both show this clustering.:
List 1 Grok
1839, near Mandalay – M7.5–8.0 (estimated)
1930, May 23, near Bago – M7.3
1930, Dec 4, near Bago – M7.2 (noted as a distinct event in some sources)
1946, Aug 12, near Tagaung – M7.7
1946, Sep 12, near Tagaung – M7.5
1956, Jul 8, near Sagaing – M7.0
2025, Mar 28, near Mandalay – M7.7

So when my Thai wife starting saying we must store things in safer places, etc. I laughed and said, 5555 there won't be another earthquake like this for decades! This morning I went and apologized...
