Question

why hot springs are common in volcanic regions

Answer 1

because the temperature will be more than 60 degrees celcius there

Answer 2

volcanic areas have a very high heat flow; the volcanoes form from the upward migration of melted rock, this brings a lot of heat up near the earth surface. Lava is a lot hotter than the rock it intrudes, and the surrounding rock heats up quite a bit as a result. 

The upper part of the earth is filled with water (even if only in small spaces and fractures), and water responds to localized heating by migrating (hot water rises and cooler water comes in to replace it from the sides), just as air does. A hot magma body in the shallow crust is a big and important heat source.
