A moderately strong earthquake shook Costa Rica this Monday, August 24 at 3:50 pm.

According to the National Seismologic Network (RSN)the earthquake had a magnitude of 6.2 and the epicenter was located 12 kilometers southwest of Jaco, Garabito, Puntarenas as a result of the subduction of Cocos plate.

A 3.2-magnitude earthquake was reported near Monroe around 6:55 p.m. on Friday, Aug. 21, 2020.
A minor earthquake near Detroit Beach rattled Downriver areas and was felt in places through the region, but left the nearby Fermi 2 nuclear power plant in a safe condition, officials said.

The 3.2-magnitude earthquake was recorded Friday evening south-southeast of Detroit Beach near Monroe by the U.S. Geological Survey, about two miles south of the nuclear plant.

The earthquake, rare for Michigan, occurred at 6:55 p.m just off the shoreline of Sterling State Park, according to USGS.

Depth was determined to be 9.2 km, or about 5.71 miles. The USGS initially reported the quake as reaching 3.4 magnitude.

20 quakes recorded in 24 hours at Taal Volcano, Philippines

Taal Volcano

Taal volcano
Twenty volcanic earthquakes were recorded at the Taal Volcano island in Batangas in the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported yesterday.

State seismologists observed a weak steaming activity that reached five meters high from the vents on the main crater between 8 a.m. on Saturday and 8 a.m. yesterday.

The volcano remains under Alert Level 1, which means it is still in abnormal condition, the agency said.

On Aug. 18, a 20-meter- high steam emission was observed from the vents of the main crater.

The quake was at a depth of 640km, with an estimated magnitude of 6.9.
A 6.9-magnitude quake struck eastern Indonesia on Friday (Aug 21), the US Geological Survey (USGS) reported, but there was no tsunami warning issued and no immediate reports of casualties or major damage.

In Kupang city, far south of the quake's epicentre in the Banda Sea, frightened residents ran outside as buildings and streetlights swayed.

"I was in the shopping centre when the quake hit," said resident Engky Nussi. "Many people ran outside as stuff started falling off the shelves and we were afraid something worse might happen."

The undersea tremor struck at a depth of more than 600km about 220km south of Katabu on the island of Sulawesi, the USGS said.

Deep quakes tend to cause less damage than shallow ones and USGS said there was a low likelihood of casualties and damage.

Comment: Only two days ago on Wed. 19 Aug. twin shallow 6.8 & 6.9 magnitude earthquakes hit Indonesia within 10 minutes of each other.

4.8-magnitude earthquake strikes Death Valley and shakes Las Vegas - at least 8 reported there in 24 hours

quake
Days after Death Valley set a record for the hottest temperature on Earth in more than 100 years, an earthquake hit within the park.

A 4.8-magnitude earthquake shook Death Valley National Park on Wednesday at about 10:30 a.m., park officials reported.

Magnitude measures the energy released at the source of the earthquake, the U.S. Geological Survey says. It replaces the old Richter scale. Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech.

A pair of powerful earthquakes has rocked the Indonesian coast, measured at 6.8 and 6.9 magnitude, according to the US Geological Survey (USGS), shaking the island of Sumatra.

The two quakes struck off Sumatra's western coast on Wednesday morning, with an estimated depth of 22 kilometers (13 miles) and 26 kilometers (16 miles) respectively. The first tremor impacted an area some 144 kilometers (89 miles) away from Bengkulu, while the second came closer to the city at 130 kilometers (80 miles).

There are no reports of injuries as of yet, however local media said the quakes shook the homes of island residents "as if a truck had passed" and did "minor damage," particularly to buildings with "poor construction."

New finds that tons of grain were transported between the Fertile Crescent (Middle East) and Eastern China 5000+ years ago before trade routes were established is making academia question the official time line of history. Additionally the mega city of Nebelivka, Ukraine which was over a mile wide, housed 15,000 people and had roads 5200 years ago with industrial agriculture before animals were used to plow fields. These civilizations were Sun worshipers. Greenland melt season stops a month early in 2020.

A partially damaged building is seen amid debris in Masbate Province, August 18, 2020, after an earthquake struck the Philippines.
A magnitude 6.6 earthquake struck the Philippines on Tuesday, killing at least one person and damaging roads and buildings including a hospital and a sports complex being used as a novel coronavirus quarantine centre.

It was the strongest earthquake in eight months in the Philippines, which lies on the "Ring of Fire," a seismically active belt of volcanoes circling the Pacific Ocean.

"My things at home fell down and my neighbours' walls cracked and some collapsed," Rodrigo Gonhuran, 30, told Reuters from the central town of Cataingan, which has a population of more than 50,000 people and is near the epicentre.

One man, a retired police colonel, was killed when his three-storey house collapsed, while four people suffered minor injuries, provincial administrator Rino Revalo told DZMM radio station.

An 3.0-magnitude earthquake has struck the English Channel just off the Sussex coast.

The tremor happened at around 9am on Thursday morning, according to the European-Mediterranean Seismological Centre (EMSC).

The earthquake, which occurred at a depth of 7km, took place in the Channel 35km south of Camber and less than 50km away from Eastbourne.

Comment: Just yesterday in the UK it was reported that there were thousands of 'apocalyptic' lightning bolts and flash floods.

Rare M6.0 earthquake hits near Dar es Salaam, Tanzania

Tanzania earthquake

A very strong dangerous earthquake was felt along the coast of Tanzania on Wednesday evening. According to USGS the epicenter was located about 80 kilometer south-east of Dar es Salaam. Moderate intensities were recorded across Daressalam and on Zanzibar island.

However, due to the distance between epicenter and coast, the impact of the quake will be reduced. Minor to moderate damage (cracked walls, etc.) is still likely in coastal areas of Pwani region. People in this area should also expect an aftershock sequence. There is no tsunami threat.

Weak intensities were also felt in parts of Kenya, especially around Mombasa. No damage should be expected there.

Earthquakes along the coast of Tanzania are relatively rare and today's event has been the strongest in decades. The seismic activity there still results from the tectonic processes along the Eastern African Rift Valley, although it runs further inland.
