Ultra-Plinian eruptions are the largest of all volcanic eruptions are more intense, have a higher eruption rate than Plinian ones, form higher eruption columns and may form large calderas. These eruptions produce rhyolitic lava, tephra, pumice and thick pyroclastic flows that cover vast areas and may produce widespread ash-fall deposits.
Kilauea, a volcano on Hawaii's Big Island, erupted early Wednesday morning in a spectacular display. Video of the eruption showed the dark night sky lit up with fire and glowing lava, which began ...
In the years before the 1883 eruption, seismic activity around the Krakatoa volcano was intense, with earthquakes felt as far away as North Australia, one of which, in 1880, damaged a lighthouse. [4] Strombolian activity began on 20 May 1883, and steam venting began to occur regularly from Perboewatan , the northernmost of the island's three cones.

The eruption caused a volcanic winter. During the Northern Hemisphere summer of 1816, global temperatures cooled by 0.53 °C (0.95 °F). This cooling directly or indirectly caused 90,000 deaths. The eruption of Mount Tambora was the largest cause of this climate anomaly. [22]

A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am. The eruption, which had a volcanic explosivity index of 5, was the first to occur in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California. [2]
