Nebraska, USA – The National Weather Service says at least two tornadoes have touched down in northeast Nebraska, causing widespread damage in the town of Pilger. The massive tornadoes claimed the lives of at least two people leaving 19 people injured and destroying more than half of the town.

Roundup of Global Volcanic Activity

Etna (Sicily, Italy): June 16 – Lava effusion and pulsating low lava fountains continued from the New SE crater throughout the night and today. Tremor remains at fluctuating elevated levels but with a now slightly decreasing trend. The lava flows have descended the western slope into the Valle del Bove where they spread into several broad fronts.

June 17 – Activity continues with little changes, at fluctuating and overall slowly decreasing intensity, reflected also by the tremor signal. Last evening, liquid lava spattering from the central vent of the New SE crater occurred at rapid succession reaching heights of 50-150 m and often throwing incandescent material to the upper outer flanks of the cone. Lava flows continued to descend through the channel on the eastern side of the cone and spread into several channels on the upper half of the Valle del Bove wall, but not extending beyond the fronts emplaced during yesterday night. The situation this morning is similar, but the spattering at the summit has decreased.

Shiveluch (Kamchatka): Explosive activity of the volcano continues. Since the larger explosion on 11 June, the volcano has only produced a few smaller explosions and ash emissions. Not much glow is currently visible on clear night-time images, suggesting that extrusive activity of the lava dome is reduced at the moment.

Batu Tara (Sunda Islands, Indonesia): Activity at the volcano is relatively intense at the moment. Several ash plumes rising to 5-7,000 ft (1.5-2.1 km) altitude, originating from stronger-than-normal strombolian explosions, were seen on satellite imagery during the past days.

Kavachi (Solomon Islands): Some intermittent eruptive activity seems to be occurring at the volcano. On 10 June, another spot of discolored water had been visible above the shallow submarine volcano.

Ubinas (Peru): Near-continuous, but light ash emissions interrupted by sporadic explosions continue at the volcano. Two stronger explosions on 12 and 13 June produced ash plumes that rose 2.5-3.5 km above the summit.

Piton de la Fournaise (La Réunion): Seismic activity above normal background levels have been detected under the volcano past week. The prefecture decided to raise the alert level and advises climbers and hikers to avoid the rims and crater walls of Dolomieu crater due to an increased risk of rockfalls and collapses.

Gigantic Underground Ocean 400 Miles beneath Earth’s Surface Discovered

Researchers from Northwestern University have discovered an enormous underground ocean 400 miles beneath earth’s surface. The lately discovered ocean is three times the volume of the oceans on earth’s surface.

Steve Jacobsen, Geophysicist of Northwestern University, and team were able to make the discovery with the help of 2,000 seismometers. Researchers studied seismic waves produced by around 500 North Americans earthquakes.

Jacobsen said the ocean is contained within highly-pressurized rock called ringwoodite. Scientists hope that their findings would be able to throw light on where earth’s oceans came from.

After studying the speed of the waves at differnet depths, scientists were able to know which types of rocks the waves were passing through and that is how, researchers concluded about the presence of ringwoodite in the transition zone 400 miles down.

Ringwoodite is a blue-colored rock that acts like a sponge due to a crystal structure allowing it to trap hydrogen and water. Jacobsen added that the hidden water may be able to explain why they have been able to remain the same for millions of years.

“If the stored water wasn’t there, it would be on the surface of the Earth, and mountaintops would be the only land poking out”, said Jacobsen. The new research adds to the existing theories that oceans originate on earth.

However, more tests will be required to move forward. The current research could only finalize that the massive reservoir exists below the continental United States. But it is unclear how far this ocean extends.

Disease

Middle East respiratory syndrome coronavirus (MERS-CoV) – update

On 12 and 13 June 2014, the National IHR Focal Point of Saudi Arabia notified WHO of 2 additional laboratory-confirmed cases of infection with Middle East respiratory syndrome coronavirus (MERS-CoV).

Globally, 701 laboratory-confirmed cases of infection with MERS-CoV, including at least 249 related deaths have officially been reported to WHO.
