Satellite data show continued deflation of Kilauea's summit  This image is an #interferogram made from radar data collected by the Cosmo-SkyMed satellite constellation operated by the Italian Space Agency (@ASI_spazio). The colored fringes show #deformation of Earth's surface towards or away from the satellite. The more fringes that are clustered together, the more deformation has occurred. Each color cycle is equivalent to 1.5 cm (0.6 in) towards or away from the satellite.

Dukono (Halmahera): (17 May) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: CONTINUOUS VA EMISSION TO FL060 OBS VA DTG:17/0600Z

Kilauea (Hawai'i): A violent explosion - the largest since 1924 - occurred this morning at the Halema'uma'u crater at about 04:15 local time, sending an ash plume to 30,000 ft (9 km) altitude, i.e. generating an eruption column of 8 km height.
The ash plume drifted northeast. "Continued emissions from the crater are reaching as high as 12,000 ft asl.", HVO reports.

Kilauea summit caldera
The most recent update from HVO/USGS on the continuing eruption of Kilauea volcano (Hawaii) stated that ash emission from the Overlook crater within Halema`uma`u has decreased. There is still an ash cloud rising up from Halema'uma'u an estimated 3 to 4,000 feet above the ground - altitudes varying with pulses of emission intensity - and drifting slowly northward from the Kilauea summit. Ashfall may occur in Hawai`i Volcanoes National Park and Volcano Village, those communities downwind that may receive ashfall should take necessary precautions.

...16 May:
Volcanic Ash Advisory Center Washington (VAAC) issued the following report: VA EM
...16 May:
The eruption in the lower east rift zone continues with no significant changes. A new fissure has opened up probably during thge night between fissure #16 and #20 and erupted small amounts of lava with spattering during a few hours.
The so-far most productive fissure #17 continues to feed a lava flow towards the ESE, but its progress has significantly slowed down. HVO estimates that it only advanced about 100 m during the past 24 hours, making the scenario of lava reaching the coast in a near future much less likely now.
