Sibayat Volcano - Sumatra - 2011

Although its last eruption was more than a century ago, geothermal activity in the form of steaming sulphuric vents
 and hot springs remains high on and around the 2094m high volcano.



Some of us walked up this road to the crater.

There were lots of steaming sulphuric fumaroles near the crater of the volcano.




Seepage of sulfurous gases has caused acidic discolouration of the small crater lake.
Unfortunately the locals have rearranged some stones.
