tatanan
nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
Wangun mugearite nalika lahar tekan lumahing bumi near vulkanik. suhu lava iku antarane 1100 1250 ° c nalika nemu menyang permukaan.
