HVO Kilauea RED/WARNING - LERZ lava eruption ongoing; small ash explosions continue from Halema'uma'u

USGS Volcano Current Alerts - 5 hours 11 min ago
May 25, 2018 09:04 - Kīlauea Volcano Lower East Rift Zone Eruption of lava continues in the area of Leilani Estates and Lanipuna Gardens. Fissure 22 continues to erupt lava that is flowing southeast to the coast and the lava ocean entry. Fountains at Fissures 6 and 13 feed lava into a channel that reached the coast yesterday forming a second ocean entry. Fissures 7 and 21 are feeding a perched lava pond and pāhoehoe flow that has advanced eastward covering most of the area bounded by Leilani Blvd, Mohala St., and the fissure line. Fissure 17 continues weak spattering, while ...

HVO Mauna Loa YELLOW/ADVISORY - Mauna Loa is not erupting. Deformation and seismicity rates remain low.

USGS Volcano Current Alerts - Thu, 05/24/2018 - 17:31
May 24, 2018 21:28 - Activity Summary: Mauna Loa Volcano is not erupting. Rates of deformation and seismicity have not changed significantly. Observations: During the past week, only a few small-magnitude earthquakes occurred beneath the volcano. The number of monthly and weekly earthquakes recorded beneath the volcano has decreased to near background levels. Global Positioning System (GPS) measurements are still dominated by after effects of the M6.9 earthquake on Kilauea's south flank on May 4, when stations moved suddenly and are slowly returning to normal trends. The trends have ...

AVO Cleveland YELLOW/ADVISORY - Unrest continues; Nothing significant in monitoring data over past day.

USGS Volcano Current Alerts - Thu, 05/24/2018 - 17:31
May 24, 2018 19:37 - Low-level unrest continues at Cleveland volcano. Nothing significant was observed in cloudy satellite images over the past day. No activity detected in seismic or pressure sensor data. Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.

HVO Kilauea RED/WARNING - LERZ lava eruption ongoing; small ash explosions continue from Halema'uma'u

USGS Volcano Current Alerts - Thu, 05/24/2018 - 14:30
May 24, 2018 18:12 - Kīlauea Volcano Lower East Rift Zone Eruption of lava continues in the area of Leilani Estates and Lanipuna Gardens subdivision. The middle portion of the fissure system (centered on Pohoiki Rd.) continues to produce the most robust eruptive activity in the Lower East Rift Zone. Overnight, field crews observed that fissure areas 2, 7, 8 and 3, 14, 21 (between Luana and Kaupili St. in Leilani Estates) reactivated and are spattering. Intermittent signals recorded on sensors closest to the two ocean entries suggest they remain active; . Volcanic gas emissions ...

Oman: Tropical Cyclone Mekunu - May 2018

Reliefweb.int - Tue, 05/22/2018 - 19:00
GLIDE number: TC-2018-000062-OMN
Disaster type: Tropical Cyclone
Affected countries: Oman, Somalia, Yemen

A new tropical storm has developed in the southwest Arabian Sea where it intensified yesterday evening into Cyclone Mekunu. The cyclone is moving currently north-northwest at a speed of 11 km/h. Mekunu is expected to continue moving in this direction during the remainder of this week and make landfall near Salalah, Oman on about Saturday 26 May. A major fluctuation in tropical weather over the southern Arabian Sea known as the Madden-Julian oscillation (MJO) is likely to cause Mekunu to strengthen further. As a result, heavy rains are forecasted for Socotra Island, followed by the southern Arabian coast from Sayhut in eastern Yemen to Salalah and Ash Shuwaymiyyah in southern Oman, which could cause local flooding and damage.
