Trade Winds Declining in Hawaii

Experts say trade winds are declining, a drop that’s slowly changing life across the islands. Part of what makes living in Hawaii so pleasant is the gentle breeze. Arriving from the northeast, it’s light enough that it is barely noticeable but strong enough to chase away the humidity.

The effects of the decline in the trade winds can be seen from the relatively minor – such as residents unaccustomed to the humidity complaining about the weather and having to use their fans and air conditioning more often – to the more consequential – including winds being too weak to blow away volcanic smog. The winds also help bring the rains, and their decline means less water. It’s one reason officials are moving to restore the health of the mountainous forests that hold the state’s water supply and encourage water conservation. Scholars are studying ways for farmers to plant crops differently.

It’s not clear what’s behind the shift in the winds. A study has shown a decades-long decline, including a 28 per cent drop in northeast trade wind days at Honolulu’s airport since the early 1970s.

These days there are fewer waves to surf because the winds are arriving less often. Sometimes the winds are too weak to blow away the volcanic smog, or vog, created by sulfur dioxide erupting from Kilauea volcano on the Big Island, leaving a white or brownish haze hanging over Honolulu. This aggravates asthma and other respiratory problems.

For now, the most important consequence will be declining rainfall and a drop in the water supply, particularly as Hawaii’s population grows and uses more water. Trade winds deliver rain to Hawaii when clouds carried from the northeast hit mountainous islands built by millions of years of volcanic eruptions. These rains, together with rainfall from winter storms, are the state’s primary sources of water. On Oahu, the rain feeds ground aquifers that supply water to about 950,000 people in Honolulu and surrounding towns. Residents are reporting streams near their homes are flowing lower than before. Scientists don’t know if this is a downward trend or just the lower leg of a long-term cycle.

Disease

Swine Flu at County Fairs Is Back

A relatively new strain of the swine flu virus that sickened more than 300 people last year is back again this summer, according to the Centres for Disease Control and Prevention.

The strain, called H3N2 variant virus, infected four people who visited a county agricultural fair in Indiana this month. None of the infected individuals were hospitalized, and none died.

Because this virus is typically transmitted from pigs to people, the CDC officials are urging people at high risk for flu complications — such as young children, the elderly and those with underlying health conditions — to avoid pigs at county fairs.

Meningitis in Russia

An outbreak of meningitis in Russia, which occurred nearly a month ago, has failed to subside yet, contrary to doctors’ forecast. The first cases of the disease were registered in Rostov-on-Don. It has spread to other cities – Astrakhan, Lipetsk and its region, Nizhni Novgorod and Moscow.

Meningitis is an inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. The inflammation may be caused by infection with viruses, bacteria, or other microorganisms.

The most common symptoms of meningitis are headache and neck stiffness associated with fever, confusion or altered consciousness, vomiting, and an inability to tolerate light (photophobia) or loud noises (phonophobia). Treatment must be started without delay, Otherwise grave complications or even a lethal outcome are likely.

Chikungunya Disease in the Philippines

The Department of Health (DoH) in the Philippines confirmed yesterday an outbreak of chikungunya disease in Patnongon, Antique, with 313 cases as of April, this year.

The symptoms of chikunguya include fever, rashes, and severe joint pains.

There is no known cure for chikungunya but it is rarely fatal.

Roundup of Global Volcanic Activity:

Fuego (Guatemala): Explosions have become more violent, the latest special bulletin of INSIVUMEH indicates. Mild strombolian eruptions have turned into more powerful vulcanian-type explosions, which eject dense ash plumes rising to 800 m and produce numerous avalanches of blocks around the crater, especially on the southern flank. Shock waves from the explosions could be felt in areas up to 15 km distance, and rattled windows and doors in houses of Panimaché, Panimaché II, Morelia, Santa Sofía, Sangre de Cristo and were sometimes heard as far as Yepocapa and Alotenango. Fine ash fall occurred in Panimaché, Morelia and Sangre de Cristo.

New Mexico Wildfires – USA

A blustering blaze burning in southern New Mexico’s Gila National Forest has swelled to 158 square miles as more than 700 firefighters work to keep up amid a record heat wave.

Fire officials said Friday that the Silver Fire continued to advance primarily on the northwestern edge of the blaze. Eastern winds fueled flames on the west flank and pushed smoked over nearby towns.

The inferno is still only 20 percent contained and burning 20 miles northeast of Silver City.

No new evacuations have been ordered, however, some area roads and highways remained closed.

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Except for a small swarm of earthquakes on 20 June, Etna continues to be calm.

Ambrym (Vanuatu): The lava lakes in Benbow and Ambrym craters have been very active during the recent weeks. A large SO2 plume is visible today on NOAA satellite data.

Pagan (Mariana Islands): The volcano continues to emit a strong steam and ash plume visible on satellite images. This activity has been typical of Pagan in the recent months, but no ash emissions could be detected.

Veniaminof (Alaska Peninsula, USA): Volcanic tremor and small explosions continue to be detected in seismic data indicating that the eruption of lava and minor amounts of ash and steam continues. Satellite images obtained over the past 24 hours show elevated surface temperatures at the intracaldera cone. Web camera images from Perryville show a small light-coloured plume rising above the intracaldera cone to just above the rim of the caldera to about 8,000 to 10,000 feet above sea level and night time images showed a persistent incandescent glow at the cone.

Pavlov (Alaska Peninsula, USA): Eruptive activity is continuing, but at a much lower level than earlier this week. The level of seismicity over the past 24 hours has continued to decline and now consists primarily of low level continuous tremor. Periods of continuous tremor are likely associated with lava fountaining and minor ash production, but at this level, emission rates are probably very low. Satellite data over the past 24 hours has shown strong thermal signals at the summit. Pilot reports from last evening have indicated that plumes are rising to levels not much above the summit of the volcano. AVO has received no reports of ash fall on nearby communities today.

Telica (Nicaragua): A new earthquake swarm started this morning, visible on INETER’s seismograms.

San Cristobal (Nicaragua): Seismic activity has been at normal, low levels during the recent days.

Masaya (Nicaragua): Seismic activity remains low.

Galeras (Colombia): Weak ash emissions occurred on Wednesday (26 June). Seismic activity otherwise has remained at low levels.

Cumbal (Colombia): INGEOMINAS reports a decrease in seismic activity during the past week, but maintains “yellow” alert level for the volcano.

Reventador (Ecuador): Weak eruptive activity continues with occasional steam and ash emissions during small explosions that create plumes reaching about 1 km.

Locusts Ravaging Madagascar

Madagascar risks having two-thirds of its crops overrun by locust swarms if it fails to act now, the U.N. Food and Agriculture Organization (FAO) warns. “This could very well be a last window of opportunity to avert an extended crisis,” said FAO Director General Jose Graziano da Silva.

The country’s worst locust infestation in 60 years had spread across a wide swath of the country by early April, and FAO says the agency has been falling short in its efforts to raise funds from Western donors to combat the plague.

“If we don’t act now, the plague could last years and cost hundreds of millions of dollars,” cautioned Graziano da Silva.

Experts say there are now more than 500 billion ravenous locusts on the island nation, chomping through about 100,000 tons of vegetation each day.

“The last (locust plague) was in the 1950s and it had a duration of 17 years. So if nothing is done, it can last for five to 10 years, depending on the conditions.”

Roundup of Global Volcano Activity:

Shiveluch (Kamchatka): A phase of intense activity occurred last night starting at 19:10 UTC, and lasting for about 40 minutes. The activity was probably a major collapse of the dome and/or accompanied by explosions. It produced a large ash plume rising to about 10-12 km altitude (VAAC Tokyo) into the atmosphere. Due to cloud cover, no direct observations could be made. A dust veil of reddish ash (likely originating from older, altered lava, suggesting that the event was largely characterized by partial collapse of the existing dome) engulfed the villages of Lazo and Klyuchi SW of the volcano where a layer of 1 and 2 mm of ash was deposited.

Krakatau (Sunda Strait, Indonesia): The group of our current trekking tour on Java climbed the summit of Anak Krakatau on 24 June. Climbing there was very difficult, because of many hot fumarolic spots and strong degassing. The summit of Anak Krakatau is now higher than before the Sep 2012 eruption. One active vent was remaining in the west part.

Veniaminof (Alaska Peninsula, USA): Effusive and weak explosive activity continue. Volcanic tremor and small explosions continue to be detected in seismic data and satellite data continue to show elevated surface temperatures at the intracaldera cone. A light colored plume is rising above the cone to just above the rim of the caldera to about 8,000 to 10,000 feet above sea level and at night, a persistent glow is visible. (AVO)

Pavlov (Alaska Peninsula, USA): The eruption had increased yesterday and produced ash plumes rising up to about 8.5 km (28,000 ft), but has decreased in strength again today. Seismicity had climbed to the highest levels since the beginning of the eruption, suggesting that the magma supply was reinvigorated into a new explosive phase. Ash fall was reported in communities to the southwest of Pavlof, including King Cove, at 48 km (30 miles) distance.

Popocatépetl (Central Mexico): Seismic activity has picked up, suggesting that the volcano could be headed for more vigorous activity soon. SO2 emissions on NOAA recent satellite data have been relatively high as well. A magnitude 3.6 volcanic quake occurred on Tuesday night 23:57 local time and was located SE of the crater at 2 km depth. Over 3 hours of low frequency and short amplitude tremor were recorded. An earthquake swarms occurred yesterday as well and another one seems to have started an hour ago.

Santa María / Santiaguito (Guatemala): Activity has not changed much overall, but the viscous lava flow on the south side of the dome has become more active and now produces frequent avalanches. INSIVUMEH warns that these can now sometimes turn into pyroclastic flows. Explosions remain rare and produce maximum plumes of about 1 km height. Ash mainly drifts to the SW and produces fine ash fall in the areas of Finca La Florida and Monte Claro.

Pacaya (Guatemala): Mild, typical strombolian activity has established itself inside the Mackenney crater. “Dry” (not containing much ash) explosions occur frequently and eject incandescent scoria to about 25 m height above the crater and an intra-crater cone, now about 15 m high, is being formed inside the crater. Some of the explosions can be heard in up to 5 km distance. At night, glow can be seen from the crater.

Fuego (Guatemala): Explosions have become more frequent and stronger. Dense ash plumes rose up to 600 m above the crater. Shock waves from the explosions made windows and roof vibrate in houses of Sangre de Cristo, Panimache, Morelia and others in the area. (INSIVUMEH)
