The lava dome at a remote Alaska volcano has resumed growing, prompting officials to raise its alert level.
The dome now fills the floor of the crater at Cleveland Volcano, 940 miles southwest of Anchorage. The Alaska Volcano Observatory Tuesday raised the volcano’s alert level to watch status. The dome is now about 394 feet in diameter. Officials say if that continues, lava flows could start on the flanks of the volcano. The growing dome also increases the possibility – but doesn’t ensure – an explosive eruption. - Alaska Public.According to the code definitions for volcanoes, the Orange Alert Level is based on the volcanism exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].
