Second consecutive year of severe coral bleaching in Hawaii

Hawaii’s reefs are already reeling from their worst coral bleaching event in recorded history in 2014, when record warm ocean temperatures caused 50 – 70% of the corals sampled in Northeast Oahu’s Kāneʻohe Bay to bleach. When the sea surface temperature is 1°C warmer than the highest monthly mean temperature corals usually experience, coral polyps will expel the symbiotic algae that live in their tissues, exposing the white skeleton underneath, resulting in a white “bleached” appearance. Death can result if the stress is high and long-lived. In Hawaii’s waters, corals cannot tolerate water temperatures above 83°F (28.3°C) for multi-week periods without suffering bleaching. Corals typically recover from mild bleaching, gradually recovering their color by repopulating their algae. However, if the bleaching is severe or prolonged, individual polyps or whole colonies will die. With Hawaii likely to undergo a second consecutive year of record warm waters and coral bleaching in 2015, widespread mortality in many of Hawaii’s coral reefs is possible, particularly around the Big Island.

Disease

Middle East Respiratory Syndrome coronavirus (MERS-CoV) – Saudi Arabia

Between 16 and 25 July 2015, the National IHR Focal Point for the Kingdom of Saudi Arabia notified WHO of 8 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, including 1 death.

Legionnaires’ Disease Outbreak Reported in South Bronx, NY

The New York City Health Department is investigating an outbreak of Legionnaires’ disease in the South Bronx. Thirty-one cases have been reported since July 10, including two possible deaths. The Health Department is also testing water from cooling towers and other potential sources in the area to determine the source of the outbreak.

New Yorkers with respiratory symptoms, such as fever, cough, chills and muscle aches, are advised to promptly seek medical attention.

Wildfires

Wildfires – Spain

The Catalonia region of Spain has seen its biggest forest fire this year, with more than 1,200 hectares (3,000 acres) burned in less than 24 hours. Helicopters have been used to contain the fire, which broke out on Sunday. Some 400 people were forced to leave their homes, but authorities said there had been no reports of injuries.

Wildfires – California

Fires burning in drought-parched California on Tuesday menaced thousands of structures as firefighters struggled to corral the blazes there and elsewhere in the U.S. West.

The so-called Lowell Fire north of the state capital Sacramento has injured four of the 2,277 firefighters battling it. One firefighter was hospitalized with serious burns. Roughly a third of the 2,233-acre blaze was contained as of Tuesday morning, with low humidity and high heat expected throughout the day. Roads were closed and evacuation warnings were in place around the fire, which was threatening about 1,800 structures.

To the south, a 1,739-acre fire forced the evacuation of campgrounds in the Sierra National Forest and threatened some 450 structures, including homes and vacation cabins. The so-called Willow Fire, north of the central California city of Fresno, was only 5 percent contained as of Tuesday morning.

Volcanos

Roundup of Global Volcanic Activity

Piton de la Fournaise (La Réunion): A new eruption might be under way at the volcano. Since last weekend, seismic activity from a source at 1-2 km depth beneath Dolomieu crater has been increasing. In addition, increased degassing and inflation of the Dolomieu crater have been detected, both likely signs of a new magma intrusion at shallow depth.

The prefecture has closed access to the Enclos. Whether an eruption will occur or not remains to be seen in the coming hours or days. If it does, it would be the third eruption of Piton de la Fournaise in 2015 after the ones in February and May.

Already on 6 July, a similar seismic swarm occurred, but was not followed by an eruption. More than 90 quakes within one hour triggered an eruption alert and the Enclos was closed to the public. The caldera was reopened (with some limitations) on 9 July.
