USGS: 5.3 magnitude earthquake strikes off Tonga's coast

Tonga
A magnitude 5.3 earthquake has occurred off the coast of Tonga in the South Pacific, the US Geological Survey (USGS) reports.

The quake occurred at 00:33 GMT on Saturday at a depth of 57.6 kilometers (about 36 miles), 246 kilometers (153 miles) south of Ohonua, the largest settlement on Tonga's 'Eua island, USGS said.

There appeared to be no tsunami threat following the earthquake and there were no immediate reports of any damages or casualties.

ExxonMobil sued for decades-long cover up of climate change's adverse affect

Oil giant ExxonMobil is being sued for allegedly polluting a Massachusetts river and violating federal water laws. The suit also charges the company with knowing of climate change's adverse affect, but hiding it.

Last year it was revealed the company started to conceal its own findings as early as 1977 that fossil fuels cause global warming.

"Communities were put in danger and remain in danger, all to cut costs from one of the most profitable corporations in the world," said Bradley Campbell, president of the Conservative Law Foundation, in a released statement about the lawsuit filed on Thursday in the Massachusetts District Court.

Comment: ExxonMobil, the world's biggest oil company, knew as early as 1981 of climate change - seven years before it became a public issue, according to a newly discovered email from one of the firm's own scientists. Despite this the firm spent millions over the next 27 years to promote climate denial.

Recent earthquake swarm under California's Salton Sea could lead to massive earthquake on San Andreas fault

The rumbling started Monday morning deep under the Salton Sea. A rapid succession of small earthquakes — three measuring above magnitude 4.0 — began rupturing near Bombay Beach, continuing for more than 24 hours. Before the swarm started to fade, more than 200 earthquakes had been recorded.

The temblors were not felt over a very large area, but they have garnered intense interest — and concern — among seismologists. It marked only the third time since earthquake sensors were installed there in 1932 that the area had seen such a swarm, and this one had more earthquakes than the events of 2001 and 2009.

The quakes occurred in one of California's most seismically complex areas. They hit in a seismic zone just south of where the mighty San Andreas fault ends. It is composed of a web of faults that scientists fear could one day wake up the nearby San Andreas from its long slumber.

An image provided by Caltech seismologist Egill Hauksson shows the earthquake swarms of 2001, 2009 and 2016 in the Salton Sea. Scientists worry that earthquakes near the southern end of the San Andreas fault could trigger a large earthquake on California's longest fault
The San Andreas fault's southernmost stretch has not ruptured since about 1680 — more than 330 years ago, scientists estimate. And a big earthquake happens on average in this area once every 150 or 200 years, so experts think the region is long overdue for a major quake.

Comment: Many experts believe the San Andreas fault is long overdue for a potentially catastrophic earthquake:

5 waterspouts photographed along St. Joseph Peninsula, Florida

Waterspouts
Saturday morning got a bit crazy for visitors and residents along St. Joseph Peninsula and Black's Island.

A front coming through generated what first appeared to be five funnels over towering over the peninsula becoming a main funnel with a second alongside and finally one main waterspout over St. Joseph Bay, coming within a couple hundreds yards or so of Black's Island.

Thanks for Carol and Phil Dohmen for the photos.

Police direct traffic in the central business district of Adelaide after severe storms and thousands of lightning strikes knocked out power to the entire state of South Australia on Wednesday night. On Thursday night the state copped another belting.

Intense low-pressure system sweeps across state, causing heavy rain, flooding and major damage after emergency services tell Adelaide workers to go home


South Australia has copped another belting with a destructive storm lashing the state just 24 hours after super cell thunderstorms knocked out the state's entire power network.

The intense low pressure system raged across Adelaide and parts of South Australia late on Thursday. The storm packed winds of up to 140km/h, among the strongest the city has experienced, prompting an unprecedented warning from police for workers to head home early and stay home amid concerns emergency services might not be able to cope.

The winds brought down trees across a wide area, causing major damage, and ripped some mid-north buildings apart.

Heavy rain caused widespread flooding, from the Patawalonga River in Adelaide, through to the Barossa and Clare valleys, which copped 54mm of rain.

Record rise in the number of deaths due to lightning in 2016 for Bangladesh

Bangladesh has witnessed a record rise in the number of deaths from lightning strikes this year, and experts say it is linked to global warming and deforestation.

Until September 20, a total of 193 people were killed in lightning strikes, beating all previous annual figures that ranged from 51 to 136 between 2010 and 2015, according to the Department of Disaster Management.

The total death toll since 2010 is 828. However, the actual number of deaths from lightning strikes could be more as it had not been considered a natural disaster until recently and not recorded by the department, an official told The Daily Star.

The record of people getting injured in lightning strikes is not maintained either.

The government declared lightning as one of the natural disasters only earlier this year, said M Khalid Mahmood, director (planning and development) at the DDM.

The district administration, as per a standing order, provides Tk 20,000 to the families that have lost a member in lightning strike.
Lightning stats

Comment: With these additional reports, here and here, the number of deaths for the year in Bangladesh now stands at 196 and it seems more than likely it will top over 200 by the end of 2016.

Hurricane Matthew batters southern Caribbean in rare shift

Tropical Storm Matthew (bottom right) spins in the eastern Caribbean Sea on Sept. 29, 2016.
People in the Dutch Caribbean islands reinforced their homes and stocked up on emergency supplies Thursday as Hurricane Matthew took a rare turn through the southern Caribbean ahead of an expected shift to the north.

Matthew was passing to the north of the islands of Aruba, Bonaire and Curacao during the night, before shifting on a course predicted to take it toward Jamaica, Cuba and Haiti over the weekend.

By late Thursday, Aruba was seeing some rain and sea surge had covered part of a road on the northwest side of the island. There were no reports of evacuations. In Curacao, some streets were flooded, and there was a light rain falling on Bonaire.

The so-called "ABC islands" of the Dutch Caribbean, which were under a tropical storm watch, are usually spared from tropical storms. Matthew's approach prompted long lines at gas stations and supermarkets. Authorities in Aruba said government offices would be closed Friday and Curacao's parliamentary elections were postponed until next week.

The government of Colombia also issued a tropical storm watch for its coast from Riohach to the Venezuelan border.

Comment: According to the Weather Channel, Hurricane Matthew became the fifth hurricane of the 2016 Atlantic hurricane season early yesterday afternoon. It is now a Category 2 hurricane that continues to undergo rapid intensification. Matthew poses a danger to Jamaica, parts of Hispañola, eastern Cuba, and the Bahamas early next week. Its potential U.S. impact later next week still remains unclear.

Roy Spencer comments:
Hurricane Matthew, with 105 mph sustained winds, is now over the south-central Caribbean. It is expected to strengthen into a major hurricane today or tomorrow, and possibly make landfall somewhere on the East Coast around next Thursday. If it does, Matthew's landfall would occur exactly 4,000 days after major Hurricane Wilma's landfall.

Hurricane Wilma, the last major hurricane (Cat 3 or stronger) to hit the U.S., struck Florida on October 24, 2005. Will Matthew arrive as the first major hurricane to strike the U.S. in almost 11 years? Only time will tell. (Sandy was Cat 1 at landfall, and technically not a hurricane at that time. Hurricane Ike, 2008, was a Cat 2.)

Mayor Drew Dilkens has declared a state of emergency for the City of Windsor and said damage to homes and businesses will be overwhelming.
Mayors in Windsor and Tecumseh, Ont., declared a state of emergency for their communities after massive flooding hit the region Thursday.

More than 190 millimetres of rain fell in Tecumseh, while 80.8 millimetres of rainfall was recorded in Windsor between 9 p.m. Wednesday and 5 p.m. Thursday.

Another 70 millimetres is expected to hit the region Thursday evening and into Friday, and a flood warning remains in effect.

"This is beyond the reasonable capacity of the city to handle," Windsor Mayor Drew Dilkens said at a news conference Thursday afternoon. "It's beyond the capacity of the residents to handle."

Dilkens said damage to homes and businesses will be overwhelming, and he plans to ask senior levels of government for help.

Basements and streets in Windsor and Tecumseh flooded as rain pummelled the region. Dilkens and Tecumseh Mayor Gary McNamara said they have never seen a storm like this one.

"This wasn't a one-in-10-year storm. It wasn't even a one-in-100-year storm," Dilkens said.

"I've never seen anything that intense in the 35 years I've been in this region," McNamara said. "This is unprecedented."
