Tengchong is located between the India Plate and
Eurasia Plate, where crustal movements are active, earthquakes
frequently happen and volcanoes often erupt. There are about 90
conspicuous cones now. Among them, 22 craters remain intact.
Around the craters is a combination of scabland, volcanic cinder
and volcanic flow, forming a wonderful view- the cluster of
volcanoes in Tengchong. Tengchong volcanoes rank first in China in
terms of their variety, size, good preservation and compact
distribution. The Tengchong Basin is surrounded by a group of
youn g dormant volcanoes, of which the most famous are Mount Dayinshan, Mount Maanshan, Mount Guipo, the Laifeng Hill, Mount
Dakongshan and Mount Xiaokongshan. Mount Dayinshan is known as
"the First Volcano" in Tengchong. The mountain is a conic volcano,
of which the crater has a diameter of 300 meters and a depth of
100 meters. Mount Maanshan, which is 5 kilometers west of the
county seat, is a conic volcano, whose top seems to have been cut
off, thus looking like a saddle. Likewise, Mount Guipo is also a
conic volcano with its top cut off. Mount Dakongshan, Mount
Xianokongshan and Mount Heishan stand in a line from north to
south, with a distance of 1,000 meters between them. Their craters
range in diameter from 300 to 400 meters and have a depth of
several dozen meters. Around the craters there are some black, or
red pumice stones which are very light and will not sink into
water, so they are called "floating stones". While visiting the
cluster of volcanoes in Tengchong, you will feel how wonderful
Nature is, and such feelings can be hardly obtained in any other
place.
