Magnitude-6.2 offshore earthquake occurs west of Guanacaste Province, Costa Rica

nnnnnnnnn
A magnitude-6.2 earthquake occurred off the northwestern coast of Costa Rica at around 12:43 Oct. 12. The epicenter was about 42 km (26 miles) northwest of Tamarindo, Guanacaste Province.

The tremor occurred at a depth of about 18 km (12 miles), and moderate shaking was probably felt in western coastal areas of Guanacaste Province, as well as light shaking throughout parts of northwestern Costa Rica and southwestern Nicaragua.

There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas.

Light-to-moderate aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.

Careful, talk of 'weather modification' could be a trap

Last week, category 4 Hurricane Helene hit the eastern coast of North America causing massive flooding and devastation across the region, leaving people stranded and homeless.

This week, Hurricane Milton - a category five hurricane - is predicted to hit Florida's west coast after forming in the Gulf of Mesico and moving eastwards.

Two such storms in less than ten days have fueled online talk of "Weather modification" from Republican politicians and alternate media personalities:



Personally, I see reason to be cautious here.

Shallow 6.6-magnitude earthquake hits Pacific Ocean near Tonga

nnnnnnn
A strong and shallow earthquake with a magnitude of 6.6 has struck the Pacific Ocean near Tonga, according to seismologists, but no tsunami warnings were issued.

The earthquake, which struck at 9:05 a.m. local time on Wednesday, was centered about 154 kilometers (96 miles) southeast of Neiafu, a town on Vavaสปu island.

The U.S. Geological Survey (USGS) said the earthquake had a preliminary magnitude of 6.6. It struck about 10 kilometers (6 miles) below the surface, making it a very shallow earthquake.

"Based on all available data, there is no tsunami threat from this earthquake," the Pacific Tsunami Warning Center said in a statement. No tsunami alerts were issued.

6.1 magnitude earthquake strikes off Indonesia

NNNNNNN
A 6.1 magnitude earthquake struck off Indonesia on Tuesday, according to the US Geological Survey.

With a depth of 588 kilometers (365 miles), the epicenter of earthquake was in Banda Sea, some 262 kilometers (162.7 miles) off Baubau city of southeastern Sulawesi province.

There was no immediate report of losses or tsunami warning.

Indonesia experiences frequent earthquakes as it is located on the Pacific "Ring of Fire," a tectonic belt of volcanoes and earthquakes.

A magnitude 6.2 quake jolted Sulawesi island in January 2021, killing over 100 people and leaving thousands homeless.

Some 2,200 people were killed after a separate magnitude 7.5 quake and subsequent tsunami in 2018.

Shallow 6.3-magnitude quake strikes near Mauritius

nnnnnnnn
An earthquake with a magnitude of 6.3 struck in the Indian Ocean near the island-state of Mauritius, the United States Geological Survey (USGS) said on Thursday.

The quake occurred at a depth of 10 kilometers, according to preliminary data.

Indonesia's Agency for Meteorology, Climatology, and Geophysics warned that the earthquake "may be capable of generating a tsunami affecting the Indian Ocean region."

Magnitude 6 earthquake strikes San Luis, Argentina region

mmmmmmm
An earthquake measuring 6.0 on the Richter scale struck the San Luis region in western Argentina.

Reuters quoted European Mediterranean Seismological Centre (EMSC) as saying that the earthquake struck at a depth of 129 kilometers below the surface of the earth, with no initial reports of damage or casualties as a result of the earthquake.

Last August, a 5.5-magnitude earthquake struck Jujuy Province in northwestern Argentina.

An earthquake with a magnitude of 6.3 was recorded near Saipan in the Northern Mariana Islands, which are a part of United States territory in the western Pacific Ocean, the United States Geological Survey (USGS) reported on Monday.

According to the report, the earthquake occurred at 3:36 a.m. local time, at a depth of 42.9 kilometers, and had an epicenter 262 kilometers northeast of Saipan.

No tsunami warning has been issued by the US Tsunami Warning Center.

Officials reported a 6.5-magnitude earthquake struck off the B.C. coast Sunday afternoon

A magnitude 6.5 earthquake struck off the southern tip of British Columbia's Haida Gwaii around 3:30 p.m. local time on Sunday afternoon.

The United States Geological Survey (USGS) reported the M6.5 quake was centered about 265 km south of Prince Rupert, B.C., and it occurred at a depth of 33 km beneath the surface.

The U.S. Tsunami Warning Center said that there was no threat of a tsunami from this earthquake

Shallow magnitude-6.3 earthquake strikes off Papua New Guinea

MMMMMM
A magnitude-6.3 earthquake struck in the Bismarck Sea off the coast of Papua New Guinea on Thursday, the United States Geological Survey said.

The shallow quake located far from land produced no tsunami warning or immediate reports of damage.

It was centred about 224 kilometres (139 miles) northeast of the city of Madang, located along the country's northern coast.

Earthquakes are common in Papua New Guinea, which sits on top of the seismic "Ring of Fire" -- an arc of intense tectonic activity that stretches through Southeast Asia and across the Pacific basin.
