Reply to comment by ESCAPE_PLANET_X in ‘Mind-blowing’ network of magma chambers found under Hawaii’s volcanoes - The discovery offers a possible solution to a long-standing mystery — how magma from the deep mantle travels to the Hawaiian surface by GeoGeoGeoGeo

Fig. 6. Cartoon summarizing observations. Eruptions and intrusions at Kīlauea cause pressure gradients to rapidly propagate through the Kīlauea transport structure to the Pāhala sill complex. Magma is injected into the Pāhala sill complex from the underlying magma- bearing volume; the sills are proximal to the plagioclase-spinel phase boundary, possibly in a polyphase coexistence region. The sills are connected to Kīlauea and the decollement/Ka‘ōiki region within the Mauna Loa edifice along continuous bands of seismicity.
