Lava flow map as of 11:00 a.m. HST, May 22. The flow field has not expanded significantly during the past day because most of erupted lava moved southward through the active lava channels and into the ocean. Note a new lava flow that was observed during this morning's overflight west of the active channels (see label). There was a single ocean entry this morning. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015. (HVO/USGS)
22 May 2018 updated lava flow map and thermal image of the ongoing eruption of Kilauea in the East Rift Zone (HVO/USGS)
This thermal map shows the fissure system and lava flows as of 06:45 am on Tuesday, May 22. The primary lava flow originates from Fissure 22, but a new flow has been active over the past day from the Fissure 6 area. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field. (HVO/USGS)

On the Big Island of Hawai’i, Kilauea’s activity proceeds without any signs of weakening. Eruption of lava and ground cracking continues in the area of Leilani Estates subdivision in the Lower East Rift zone. Monday 21 May lava was being erupted from multiple points along the northeast end of the active fissure system. HVO/USGS reported that whilst fissures 6, 17 and 19 only showed intermittent spattering, fissure 20 was erupting a short line of low lava fountains feeding a channelized lava flow that reached the coast. By the evening of 21 May there was only a single lava ocean entry left. Over the course of Tuesday 22 May, most eruptive activity in the Lower East Rift Zone shifted to the middle portion of the system of fissures. Lava fountains were being ejected from fissures 6 through to fissure 22 and some weak spattering occurred from fissures 5, 6, 17 and 19. A new area of fountaining started in the afternoon along the fissure line between Kaupili and Mohala Streets near Fissure 23. [lire toutes]

Ash plume rising up from Mt Merapi's summit after an explosion in May 2006 (Tom Pfeiffer / VolcanoDiscovery)
After the stratovolcano's sudden large phreatic explosion on Friday 11 May a series of smaller phreatic eruptions have occurred in the past few days which caused light ash fall in the vicinity. Phreatic eruptions are caused when underground water comes into contact with lava from Mt. Merapi, causing superheated vapor that breaks through its summit dome. In response, the volcano's alert level was raised from 'normal' to 'caution', the third-highest level, and local authorities closed all access to the volcano in a radius of 3 km from its summit.
