Shallow M6.7 earthquake hits Vanuatu

Earthquake at Vanuatu's sparsely-populated Ambrym island.

The quake struck at a moderate depth of 30 kilometres with the epicentre just off the northern tip of Vanuatu's sparsely-populated Ambrym island.
A 6.7-magnitude earthquake hit the Pacific island nation of Vanuatu on Wednesday morning, the US Geological Survey said, but no tsunami warning was issued.

The quake struck at a moderate depth of 30 kilometres with the epicentre just off the northern tip of Vanuatu's sparsely-populated Ambrym island.

The Pacific Tsunami Warning Centre said there was no tsunami risk.

"Shaking would have been felt throughout the whole of Vanuatu," Geoscience Australia senior seismologist Eddie Leask told AFP.

"But it's hard to tell whether it will cause damage. It's reasonably shallow but it all depends on the buildings, soil type and so on."

On its website, Geoscience put the potential damage radius at 63 kilometres.

Major 7.3 earthquake strikes northern Venezuela, causing minor damage - Largest quake in 118 years

People evacuate a building following tremors in Caracas after an earthquake hit the Northern Venezuela coast
A powerful earthquake with a magnitude of 7.3 has struck the northern coast of Venezuela, forcing the Pacific Tsunami Warning Center to briefly issue a warning for coastal areas within a 300 km radius of the epicenter.

The deep jolt, registered by USGS at depth of 123 km, was most strongly felt around the Gulf of Paria area but has also shaken buildings in the capital, Caracas. However, according to the Venezuelan Seismological Research Foundation, the earthquake was somewhat smaller and a lot more shallow, measuring 6.3 in magnitude and less than a kilometer deep.

After issuing an initial tsunami warning for the Venezuelan coast and neighboring Trinidad & Tobago, as well as Grenada, the Pacific Tsunami Warning Center (PTWC) updated its alert, noting that "there is no tsunami threat from this earthquake." People along the coast are still asked to "remain observant" and to exercise "caution" near the sea. Sea fluctuations "up to 30 cm" above or below normal tide may still take place over the course of the next few hours along the coastal areas, the PTWC advised.

Comment: According to USGS, there have been 17 previous earthquakes with magnitude of over 6 in the region, though large earthquakes are rare. Tuesday's quake was the largest within 155 miles (250 kilometers) of this location in over a century. See our Earthquakes topic section for more recent increased seismic activity.

Now for the big question: is it 'just a coincidence' that this quake strikes Venezuela, and not far from Caracas, at this time? Socio-political upheaval mirrored in planetary upheaval?

Or could there have been some measure of 'direction' (as we suspect happened with the Haiti earthquake in 2010)?

At the very moment this one struck, Venezuela's leaders were celebrating a "revolutionary" new economic plan they hope will rescue Venezuela's stricken economy:
According to Associated Press, the confusing moments after the quake were captured on state television as Diosdado Cabello, one of Venezuela's most powerful politicians, was delivering a speech at a pro-government rally. "Earthquake!" many members of the audience cried, pointing to the ground, as Cabello and others looked from side to side.

Yet MORE earthquakes hit Lombok, Indonesia - 6.9 and 6.3 magnitude quakes cause landslides

A second earthquake has hit in the northeast of Lombok in less than 24 hours

A second earthquake has hit in the northeast of Lombok in less than 24 hours
A magnitude 6.9 earthquake has hit to the northeast of the Indonesian island of Lombok.

The US Geological Survey had originally measured the quake at magnitude 7.2 but has revised that figure and says it hit near to the island at a depth of 20 kilometres.

It comes just hours after a 6.3 earthquake caused landslides and damage to houses on the popular holiday island.

Video shot by the Indonesian Red Cross showed huge clouds of dust billowing from the mountain's slopes after the earlier tremors struck.


Comment: How many is that now? 4 major quakes on Lombok in less than a month?

A 6.3 magnitude earthquake has hit the Indonesian island of Lombok - the latest in a series of tremors
A strong 6.3-magnitude earthquake rocked the Indonesian island of Lombok on Sunday, sending people fleeing into the streets just two weeks after a quake which killed more than 460 people.

The quake was centred west-southwest of Belanting town in East Lombok, the US Geological Survey said, at a relatively shallow depth of seven kilometres.

Residents said the earthquake was felt strongly in East Lombok.

"I was driving to deliver aid to evacuees when suddenly the electricity pole was swaying. I realised it was an earthquake.

"People started to scream and cry. They all ran to the street," East Lombok resident Agus Salim told AFP news agency.

The tremor was also felt in the island's capital Mataram and on the neighbouring resort island of Bali.

A powerful magnitude 7.9 quake has struck in the Pacific Ocean, 291 km (180 miles) from Ndoi island of Fiji, according to the United States Geological Survey (USGS). The quake hit at a depth of 570km (354 miles), too deep to cause a tsunami. Its power approaches the strongest deep-focus (over 300km deep) quake on record, the magnitude 8.3 Okhotsk Sea quake of 2013.

Strong and shallow M6.1 earthquake strikes Costa Rica

earthquake costa rica M6.1 August 18 2018
A strong and shallow earthquake registered by the USGS as M6.1 hit Costa Rica at 23:22 UTC (17:22 local time) on August 17, 2018. The agency is reporting a depth of 15.9 km (9.8 miles). EMSC is reporting M6.1 at a depth of 44 km (27.3 miles). This earthquake can have a low humanitarian impact based on the magnitude and the affected population and their vulnerability.

The epicenter was located 18.4 km (11.5 miles) W of San Vito (population 3 981), 47.2 km (29.3 miles) SSE of Buenos Aires (population 11 680), Costa Rica and 54.8 km (34.1 miles) W of Volcan (population 10 286), Panama.

There are about 880 000 people living within 100 km (62 miles) and 4 700 within 10 km.

Some 25 000 people are estimated to have felt strong shaking, 165 000 moderate, 2 052 000 light and 12 661 000 weak.

The USGS issued a green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.

Comment: Below are some of the most notable quakes in just the last two weeks or so; Alaska has seen its strongest quake ever recorded, there have been many quakes reaching magnitude 6, and in diverse locations, and there have been earthquake swarms - our planet really is rocking and rolling: Also check out SOTTs monthly documentary: SOTT Earth Changes Summary - July 2018: Extreme Weather, Planetary Upheaval, Meteor Fireballs

Earthquake strikes north east of Raba, Indonesia on Friday (Aug 17).
A relatively deep offshore earthquake struck the Indonesian archipelago late on Friday (Aug 17), according to data from the US Geological Survey.

The magnitude-6.6 quake was located 153km north-east of Raba at a depth of 564.7km, the USGS said.

Indonesia's Meteorology, Climatology and Geophysics Agency (BMKG) said in a tweet there was no tsunami risk.

Netizens took to social media to share news about the earthquake, with some saying they had felt it in Bali, about 580 km from Raba.

The epicentre of Friday's quake was around 500km from the island of Lombok, where two deadly tremors - and dozens of aftershocks - wreaked widespread damage earlier in the month.


A magnitude-6.2 earthquake rocked Lombok on Aug 9, sparking panic after a powerful earthquake just four days earlier.

Indonesia sees frequent earthquakes as it is situated on the Pacific Ring of Fire.
