Puas kub lossis txias?
Definition: A lahar is a kub lossis txias sib tov ntawm cov dej thiab pob zeb tawg uas ntws sai sai rau ntawm qhov chaw siab tshaj ntawm lub roob hluav taws. Lawv txav mus txog 40 mais toj ib teev los ntawm cov hav thiab cov kwj dej, txuas ntxiv ntau dua 50 mais ntawm lub roob hluav taws. Lahars tuaj yeem tsim kev puas tsuaj loj heev thiab ua rau tuag taus ntau dua li lava ntws.
