brazil quake jan 2019
A powerful earthquake has shaken northwestern Brazil near its border with Peru, affecting a remote part of the Amazon rainforest. There were no immediate reports of damages.

The U.S. Geological Survey said the magnitude-6.8 quake had an epicenter 55 miles (89 kilometers) west of Tarauaca, Brazil, and 204 miles (329 kms) east of Pucallpa, Peru. It hit at 2:25 p.m. local time and had a depth of 575 kilometers.

The Seismological Observatory of the University of Brasilia said on its website that it was a "deep, no risk earthquake" in the jungle state of Acre.

A powerful 7.1-magnitude quake hit the Peru-Brazil border in August.

Greenland Crater - The 12,000 year old comet that erased ancient civilization

Ancient Impact

NASA recently discovered of a massive, 19-mile (31km) wide crater, found hidden underneath Greenland's Hiawatha Glacier. This crater is the result of an asteroid impact, from a nearly 1 mile-wide mountain of iron, weighing somewhere around, get this, 11-12 BILLION tons, and was traveling at approximately 12 MILES per second - which is equivalent to more than 43,000 miles per hour - when it slammed into the earth some 12,000 years ago - And...with the mind-boggling force of essentially a 700-megaton bomb. And without a doubt, THIS is the reason why there is so much mystery and why we know so little about lost Ancient human civilization

John Woodrum, shovels his car on Sunday, Dec. 9, 2018, in Roanoke, Va. A massive storm brought snow, sleet, and freezing rain across a wide swath of the South on Sunday — causing dangerously icy roads, immobilizing snowfalls and power losses to hundreds of thousands of people.
2018 has been a hell of a year, and 2019 promises to be even more "fun." What can we expect? Christian breaks it down, from the geophysical to the geopolitical, in this Ice Age Farmer special edition.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) recorded a total of 171 aftershocks as of 8:00 a.m. on Monday (December 31) following a magnitude 7.2 earthquake in Davao Oriental.

The center of the earthquake was recorded near Governor Generoso in Davao Oriental on Saturday (December 29) triggering a tsunami alert but was immediately lifted by the agency.

According to DOST Undersecretary Renato Solidum, a series of aftershocks can still be expected though of lower intensity in the coming days.

He also noted a slight rise in sea level which reached 0.08 meters based on the data recorded from the level sensor located in Mati area.

Strange 'lava-type flow' oozing from ground creates panic in North East India village

lava flow in India
A volcanic lava type inflammable liquid has been reportedly profiting out of the ground in Tripura's Jalifa village and has triggered panic among the local residents of the area. It has gradually become a matter of concern for the Tripura state government, in North East India, which is highly vulnerable to earthquakes as it lies in seismic zone V.

This is the third such incident reported this year the state which is very close to Chittagong in Bangladesh.

Earlier in mid-April, at two spots, namely Baishnavpur and Ghagrabasti of Sunroom, lava-like liquid erupted along with fire and gas.

In the recent incident from a few days ago, the local villagers of Jalifa were scared to find lava erupting from the lower portion of the electric pole on the roadside and reported the matter to the fire extinguishing team and local police. A team of firefighters rushed to the spot and tried to spray water and foam, but failed to stop the ongoing eruption that had already burned the spot.

Meanwhile, scientists from the Department of Science, Technology and Environment of the Government of Tripura also visited the spot. After examining the spot and analysing the samples collected from the spot they concluded that the fire, smoke and other materials running out of the ground is due to a fault line that passes through that area beside the displacement of the underground tectonic plates in that region and which is creating huge subsurface heat causing the incident.

Comment: A few months ago a mysterious burning hole with flames shooting out of it was discovered in Midway, Arkansas which baffled geologists. See also:

Tsunami alert lifted after undersea M7.1 earthquake off Philippines

The earthquake struck off the southern Philippine island of Mindanao.
A strong undersea earthquake struck off the southern Philippines on Saturday and the head of the country's quake-monitoring agency advised people in a southeastern province to avoid beaches in case of a tsunami.

No casualties or damage have been reported, and the Pacific Tsunami Warning Centre lifted its warning for a potential tsunami that could hit coastal areas of the southern Philippine and Indonesia.

The Philippine Institute of Volcanology and Seismology said that the quake was detected at a depth of 49 kilometres (30 miles) and a magnitude of 7.1 about 162 kilometres (100 miles) off Davao Oriental province.

It said that it could generate aftershocks but the agency did not expect any damage.

The US Geological Survey said the quake hit at a depth of 60 kilometres (37 miles) and measured 6.9.

Renato Solidum, who heads the quake-monitoring institute, said that a major tsunami was unlikely given the depth of the quake and other factors but advised villagers to avoid the beach in Davao Oriental province and outlying regions for about two hours after the quake struck around noon as a precaution.

The quake was felt in some coastal areas, he said.

Indonesia's Meteorology and Geophysics Agency said the quake doesn't have a potential to cause a tsunami affecting Indonesia.

People stand on the street after an earthquake was felt across northern Venezuela, in Caracas, Venezuela December 27, 2018.
An earthquake with a magnitude of 5.6 hit northern Venezuela early on Thursday, the United States Geological Survey (USGS) said, with witnesses reporting tremors more than 100 km (60 miles) from the epicenter. The quake was recorded 4 km northeast of San Diego at 0859 GMT at a depth of about 10 km, according to the USGS website.

"The whole house shook," said a witness in Club de Campo, 102 km from the epicenter, in a posting on the European-Mediterranean Seismological Centre (EMSC) website.

Another witness said the quake lasted five or six seconds.

There were no immediate reports of casualties or significant damage.

Very shallow M5.5 earthquake hits Zimbabwe and Mozambique

Zimbabwe earthquake
An earthquake with a preliminary magnitude of 5.5 has struck the border of Zimbabwe and Mozambique, with shaking felt as far away as Harare, seismologists say. There was no immediate word on damage or injuries.

The tremor, which struck at 7:37 a.m. on Saturday, was centered near Espungabera in central Mozambique, about 54 kilometers (33 miles) southeast of Chipinge and 92 kilometers (57 miles) northwest of Massangena.

The U.S. Geological Survey (USGS) puts the magnitude at 5.5 with a depth of 7.6 kilometers (4.7 miles), making it a very shallow earthquake. The European-Mediterranean Seismological Centre puts the magnitude at 5.6.

There was no immediate word on damage or casualties, but the USGS estimates that up to 21 million people could have felt the earthquake, including 274,000 people who may have felt "strong" to "very strong" shaking.

"Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake resistant construction," the USGS said in its assessment. "Some casualties and damage are possible and the impact should be relatively localized."
