The Volcano is a location introduced in Monster Hunter 2. Much larger than its Monster Hunter predecessor, the region is also far more harsh and inhospitable. Lava flowing in this region is dangerous to walk near, and it overflows at night time causing some changes in the layout. You can find explosive rocks in some areas which will react to enough damage.
