A considerable quantity of gas is continually escaping from the same orifices with the water.

Though the springs are only a few yards apart, they have very different temperatures; and this appears to be the result of an unequal mixture of cold water: for those with the lowest temperature have scarcely any mineral taste.

After the great earthquake of 1822 the springs ceased, and the water did not return for nearly a year.
They were also much affected by the earthquake of 1835; the temperature being suddenly changed from 118 to 92 degrees.

Caldcleugh in "Philosophical Transactions" 1836.) It seems probable that mineral waters rising deep from the bowels of the earth would always be more deranged by subterranean disturbances than those nearer the surface.

The man who had charge of the baths assured me that in summer the water is hotter and more plentiful than in winter.
