Scientists analyzed the seismic waves that locomote through the volcano to empathize the internal construction of the volcanic system. Using the seismic data, the researchers developed a three-dimensional velocity model of a magma anomaly to decide the size, depth too composition of the lava chamber, which is several kilometers inwards diameter too located at a depth of 8-11 km (5 — 6.8 miles).
“It was known earlier that Kilauea had small, shallow magma chambers,” said Guoqing Lin, UM Rosenstiel School assistant professor of geology too geophysics too atomic number 82 writer of the study. “This written report is the root geophysical observation that large magma chambers be inwards the deep oceanic crust below.”
The written report too showed that the deep bedchamber is composed of “magma mush,” a mixture of 10-percent magma too 90-percent rock. The crustal magma reservoir below Kilauea is like to those widely observed beneath volcanoes located at mid-ocean ridges.
“Understanding these magma bodies are a high priority because of the gamble posed yesteryear the volcano,” said Falk Amelung, co-author too professor of geology too geophysics at the UM Rosenstiel School. “Kilauea volcano produces many small-scale earthquakes too paying detail attending to novel seismic action close this trunk volition aid us to meliorate empathize where futurity lava eruptions volition come upwardly from.”
Scientists are nonetheless unraveling the mysteries of the deep internal network of magma chambers too lava tubes of Kilauea, which has been inwards continuous eruption for to a greater extent than than xxx years too is currently the close active volcano inwards the world.
