Earthquake activity continues in Bárðarbunga, in the northern part of the dike intrusion and in Herðubreiðartögl. Total of 70 earthquakes have been detected since midnight, the largest M5,7 at 07:08 in the Bárðarbunga caldera. The lava has reached the western channel of Jökulsá á Fjöllum. Steaming occurs.
请大神解读这句,Steaming occurs.是否为射气喷发,是否可以解读为要冰下爆发了?
