Earthquake Swarm – California

An earthquake swarm is continuing to rattle the South Bay near Hollister. In the past four days, more than 39 tremors have hit the area on a section of the San Andreas system known as the Calaveras Fault.

Florida ‘Earthquake’ Caused By 10,000-Pound Navy Bomb

A mysterious “earthquake” detected off the Florida coast over the weekend was actually the result of testing by the U.S. Navy, U.S. Geological Survey officials report.

Seismographs as far away as Minnesota, Texas and Oklahoma registered a 3.7 magnitude event around 4 p.m. Saturday, about 168 nautical miles east-northeast of Daytona Beach Shores, the Daytona Beach News-Journal reported.

But it appears those readings were triggered by a manmade explosion designed to test the seaworthiness of a new U.S. Navy vessel, the USS Jackson.

North Dakota, USA – Baseball-sized hail, flash floods and high winds have hit North Dakota. The weather service advised residents in Grand Forks to avoid flooded roads. Reports of damage from the storm, especially in Pembina and Cavalier indicate substantial damage from the hailstones and high winds with roofs, windows, cars bearing the brunt of the hail while numerous trees were also uprooted.

Extinction threat for South Africa’s great white sharks

They have roamed South Africa’s waters for millions of years but South Africa’s great white sharks are swimming dangerously close to extinction.

This is according to the “gloomy” findings from a groundbreaking six-year great white research project, the results of which were released this morning in Cape Town.

The research by a team led by Dr Sara Andreotti and her colleagues from Stellenbosch University as well as “Shark man” Michael Rutzen of Shark Diving Unlimited, reveal there are 353 to 522 great white sharks left on the country’s coastline.

This is 52% fewer than what was estimated in previous similar studies, explains Andreotti.

The findings are based on six years of fieldwork in South Africa’s shark mecca, Gansbaai, and along the South African coastline.

South Africa’s great whites, says Andreotti, are in double jeopardy. “Not only do these sharks have the lowest genetic diversity of all white shark populations worldwide; there are also only between 353 to 522 individuals left.”

Andreotti blames some of the reasons for the sharp decline on the impact of shark nets and baited hooks implemented on the eastern seaboard of South Africa.

Other contributing factors are poaching, habitat encroachment, pollution and depletion of their food sources. The survival of white sharks in South African water is also threatened by the illegal poaching for trophies (jaw sets) and fins.

Global Warming

2016: Hottest Year Ever?

This year may be only half over, but 2016 is already on track to be the hottest year ever on record, with each of the first six months, from January to June, setting new temperature records, NASA officials announced this week. For the first time, NASA shared a midyear climate analysis, doing so because temperature averages this year have been so in excess of previous data.

NASA’s data showed that each month in 2016 was the warmest respective month globally in the modern temperature record, which dates to 1880. This trend suggests 2016 will surpass 2015 as the hottest year on record, NASA said.

So far this year, the planet’s average temperature has been 2.4 degrees Fahrenheit (1.3 degrees Celsius) warmer than the late 19th century. In 2009, international climate negotiators agreed in the Copenhagen Accord that warming should not increase more than 2 degrees Celsius (3.6 degrees Fahrenheit) this century. The Accord’s temperature threshold was put in place to hopefully avoid the worst impacts of climate change.

A strong El Niño this past year did contribute to these temperatures, but Schmidt said the continued warming trend is mostly due to the effects of greenhouse gases. While the impacts of El Niño will dissipate by 2017, leaving temperatures slightly lower than this year, Schmidt said 2017 will still average to 1 degree C (1.8 degrees F) above the pre-industrial average.

Volcanos

Roundup of Global Volcanic Activity

Etna (Sicily, Italy): The volcano remains calm at the surface but is restless. Its internal seismic activity continues to be higher than normal and SO2 gas emissions have increased a bit recently (to approx. 7,000 tons/day), which could indicate the influx of fresh magma.

Additionally, occasional small ash puffs, along with pulsating gas emissions, have been observed at the New SE crater since 10 July. These are likely signs of deep-seated explosive activity (degassing from the magma column inside the conduit). Volcanic tremor remains currently stable with no clear trend, but this can change quickly.

Bagana (Bougainville Island, Papua New Guinea): The volcano’s activity seems to have increased a bit during the past days although it is currently unknown what is exactly going on (growing lava dome? effusion of lava flows?).

Overall heat emission (by presence of new lava in its summit area) has become stronger and smaller ash plumes drifting from the volcano to distances of 20-30 km have been reported more frequently by Darwin VAAC.

Sinabung (Sumatra, Indonesia): The volcano’s activity has not changed significantly. Several smaller explosions with ash plumes about 1000-1500 m height occurred over the past days and this morning.

Kilauea (Hawai’i): No significant changes have occurred over the past days. The lava flow in the coastal flat remains active, but has not advanced in the past days. The flow front remains stalled at 850 m (0.5 miles) from the coast.

The active lava lake in Halema’uma’u crater is currently 25 m (82 ft) below the crater rim. Seismic activity and degassing are at normal levels.

Pavlof (Alaska Peninsula, USA): Seismic activity of the volcano has increased again during the past 48 hours. Satellite data show at least some small ash emissions have taken place although the Alaska Volcano Observatory does not speak of a new eruption taking place (such ash emissions could be related to collapses in the crater etc without new magma erupting).

The current Volcano Alert Level on the USGS scale is “Advisory” and the current Aviation Color Code is YELLOW.

Wildfires

Wildfires – Catalonia, Spain

The heat wave which is lashing Catalonia this week has forced the Catalan Government to set the alert level for forest fires at its maximum. In particular 30 regions have been warned of high risk of wildfires and 17 municipalities have totally restricted those activities which may increase this risk. The worst episode so far was on Tueday, since 86 wild fires hit different regions of Catalonia simultaneously. However, the most important one occurred this Tuesday in Vallbona de les Monges, a small village 40 kilometres west from the city of Lleida. In less than 5 hours, the fire burned nearly 900 hectares, most of them cereal crops. The firefighters sent 55 land resources and 3 aerial’s, which achieved to stabilise the fire by Wednesday morning. However, they continue to water the perimeter to prevent the fire from reviving.

Wildfires – Russia

A huge wildfire, raging in Russia’s far eastern Yakutia region for the past three weeks, has been extinguished, a forest official said on Wednesday.

The wildfire, covering an area of more than 3,000 hectares of woods, was raging in the Lena Pillars Nature Park, a world natural heritage site, since June 28.

Yakutia has so far this year witnessed 109 wildfires, destroying 8,000 hectares of woods.

The area of wildfires in Russia has decreased by seven percent over the weekend, from 15,400 to around 14,400 hectares

Disease

Dengue Fever in the Philippines

Dengue in the PhilippinesOfficials with Philippines Department of Health (DOH) report that the number of dengue fever cases reported from the beginning of the year through June 25 is nearly 36 percent higher than the same period in 2015 when the archipelago reported in excess of 200,000 cases.

To date, DOH there were 57,026 dengue cases recorded nationwide, compared to 42,026 cases last year during the first six months. In addition, dengue related fatalities are up–248 compared with 148 in 2015 during the same period.
