What Is the Opening at the Top of a Volcano Called.
Residents in the immediate area were told to evacuate, and two nearby community centres were serving as shelters for people and pets.
Volcanoes are ruptures on the crusts of planets, such as the Earth. These ruptures allow hot gases and lava, as well as volcanic ash, to leave the magma chamber under the planetary surface. Volcanic vents come in a variety of shapes and sizes, depending on the gas content of the magma that leaves the volcano. Examples of these shapes and sizes include spatter vents, cinder cones and satellitic shields.
Thousands of people have fled their homes on Hawaii’s Big Island because of lava and toxic gases, and dozens of homes have been destroyed.
Not only can the collapse events cause the lava to flow over, it also causes what feel like earthquakes on the island. Those quake events have plagued residents on the island for more than two months now. Each time the caldera, the part of land over the magma pit, falls a bit as the lava drains, a collapse event occurs. Each event causes anywhere from one to two meters of drop, according to the United States Geological Survey .

"Areas downslope of erupting fissures are at risk of lava inundation. The general area of Leilani Estates remains at the greatest risk," the USGS said. "However, as the eruption progresses, other areas of the lower East Rift Zone may also be at risk."
The removable Easy Valve Balloon allows a large freedom of movement and an application independent of the Volcano .
The volcano's frequent large eruptions have covered much of Iceland with tephra , and these layers can be used to date eruptions of Iceland's other volcanoes. Approximately 10% of the tephra created in Iceland in the last thousand years has come from Hekla, amounting to 5 km 3 . Cumulatively, the volcano has produced one of the largest volumes of lava of any in the world in the last millennium, around 8 km 3 .
