Storms and Floods

Cyclone Zane forms off Australia’s north Queensland coast

Tropical cyclone Zane, packing 100km/h winds, has formed off far north Queensland on the last day of the official cyclone season. The category-one system is predicted to hit the Queensland coast near Lockhart River on Cape York sometime tomorrow.

Massive landslip in Dorset, England

Landslip occurred at St Oswald’s Bay, east of Durdle Door, on the Dorset coast. Several landslides occurred earlier this month at nearby White Nothe.

Floods in Oman

Heavy rainfall caused flooding in Wadis. At least 30 people were rescued from Ibri, Oman. At least 320 people have had to be rescued in the last seven days.

Lightning strikes have claimed two lives. At least three others were injured.

Power outages have also been reported in Ghubra and Al Khuwayr, Muscat.

Landslide in North Carolina, USA

Heavy rainfall has caused a landslide in North Carolina near the Tennessee border. The landslide also hit homes on Robert’s Hill Road just outside Marshall.

China Bird Flu – Update

The reach and number of H7N9 infections in China continued to expand over the past 3 days, with Hunan province reporting its first case and four others reporting six more, lifting the outbreak’s total to 126.

Valley Fever Outbreak in San Francisco’s Prisons

The federal receiver who controls medical care in California’s prisons is ordering thousands of high-risk inmates out of two Central Valley prisons in response to hundreds of hospitalizations and dozens of deaths due to valley fever.

The state corrections department has been ordered to exclude black, Filipino and other medically risky inmates from the two prisons because they are more susceptible to the airborne fungal infection, which originates in the region’s soil.

The receiver’s office says the order will affect about 40 percent of the more than 8,200 inmates in Avenal and Pleasant Valley state prisons.

Roundup of Global Volcanic Activity:

Mount Etna Erupts again with spectacular fireworks:

1C0A9EFDAEEC7935AB8E7CF68CE8CB25

Stromboli (Eolian Islands, Italy): Spattering and lava effusion have increased from the NE hornito, feeding a new relatively large sustained lava flow on the Sciara del Fuoco. Activity has decreased a bit yesterday, but strong explosions and small lava overflows from the NE crater rim and a vent at the outer flank continued, accompanied by frequent rockfalls on the Sciara. At the moment, activity seems to be increasing again.

Batu Tara (Sunda Islands, Indonesia): New explosions have produced ash plumes rising to 7,000 ft (2.1 km) altitude this morning.

Paluweh (off Flores Island, Indonesia): Activity from the lava dome continues. A larger event (explosion and/or dome collapse) produced a fairly large ash plume rising to 10,000 ft (3 km) altitude that drifted 60 nautical miles NW this morning (VAAC Darwin).

Gaua (Vanuatu): The Wellington VAAC reported on 29 April that a Qantas Airline pilot noticed a possible ash plume from Gaua volcano.

The Vanuatu Geohazards keeps the alert at 1 (on a scale of 0-4)

White Island (New Zealand): Geonet has lowered the alert level of the volcano back to green (normal), following a gradual decline in seismic activity over the past weeks. Degassing remains intense, and after heavy rainfall during the recent past, a lake has been re-established at the main crater.

Popocatépetl (Central Mexico): Activity at the volcano has picked up in the past 48 hours. Following an earthquake swarm on Saturday with volcanic-tectonic quakes of magnitudes up to 2.3, which was probably the result of a new magma batch rising, an increase in small emissions occurred yesterday with 71 events registered during 24 hours. The largest emission yesterday (at 10:33 local time) produced a steam and ash plume rising 1.2 km above the crater and drifted NE.

Fuego (Guatemala): Effusive activity has increased on the expense of weaker explosive activity. The two lava flows on the SW flank towards the Taniluyà and Ash canyon have reached 900 and 700 m length, respectively, and cause frequent avalanches (visible on the seismograph) that reach the vegetation.

Telica (Nicaragua): Seismic activity has decreased a bit in energy recently. Although the frequency of earthquakes has slowed down, the quakes, still above background levels, are now of higher magnitude.

Tungurahua (Ecuador): Following the initial explosions and ash emissions on Saturday, a significant new eruptive phase has started at the volcano. From 05h30 yesterday morning (local time), an explosion created a steam-ash column rising 4 km initially, then decreased and remained more or less sustained at 2.5 km height above the crater for 30 minutes. The plume drifted W and SW to more than 100 km and caused light ash falls in areas near and around the volcano, such as Banos, Chacauco, Bilbao, Cusúa, Juive Grande, Pondoa and Pillate.
