A swarm of earthquakes shook southern El Salvador on Sunday, damaging nearly 200 homes and touching off small landslides, but there were no reports of serious injuries or deaths.

The U.S. Geological Survey said at least nine quakes of magnitude 4.3 or greater struck the region beginning in the morning, including three of magnitude 5.2 to 5.6.

Civil defense director Jorge Melendez said at a news conference that 11 homes were destroyed and considerable damage was done to 180 more. Most of the structures affected were made of bahareque, a material composed of cane or sticks mixed with mud and straw.

The government was transporting tents to the zone to shelter residents left homeless.

An alert was declared for some municipalities in the departments of Chirilagua, San Miguel and La Union, and classes were suspended for Monday in those areas.

Melendez said one of the quakes unleashed landslides on a highway leading to Playa El Cuco, one of the most visited tourist beaches in the area.

USGS geophysicist Don Blakeman said the earlier quakes were likely foreshocks to the magnitude 5.6 event, which hit just after 1 p.m. local time. Its epicenter was located offshore in the Pacific, about 8 miles (12 kilometers) from the town of Intipuca, at a depth of 6 miles (10 kilometers).

Comment: The Ministry of Environment and Natural Resources tweeted yesterday: "Swarm in Chirilagua-Intipucá: Until 6:00 a.m. [12:00 GMT] on May 9 a total of 747 earthquakes have been recorded, 110 earthquakes felt:"

Seismic activity seems to be increasing recently. See also:

The quake struck off the coast of Papua New Guinea
An earthquake of magnitude 6.2 struck of Papua New Guinea in the southwest Pacific Ocean on Wednesday, the United States Geological Survey said.

There were no immediate reports of damage or casualties in the quake, which struck at a depth of 52 km (32 miles) about 97 km (60 miles) south of the town of Rabaul.

Earthquake at coal mine in Poland leaves 1 miner dead and 3 missing, shakes houses

NoneFamilies waiting for a word about miners who have gone missing after a tremor at the Zofiowka coal mine in Jastrzebie-Zdroj in southern Poland

Families waiting for a word about miners who have gone missing after a tremor at the Zofiowka coal mine in Jastrzebie-Zdroj in southern Poland, on Saturday, May 5 , 2018. Seven miners went missing after the strongest ever tremor at the mine. Two of them were found hours later conscious but hurt, while rescuers continued their search for the other five missing miners.
Polish rescue workers on Sunday found the body of 38-year-old coal miner, the first fatality after an earthquake hit a coal mine in southern Poland.

Three other miners have been missing some 900 meters (2,950 feet) below ground since Saturday morning at the mine in the town of Jastrzebie-Zdroj, close to Poland's border with the Czech Republic. One of them has been located but was not rescued yet, a mining official said Sunday.

The head of the Jastrzebie Coal Company, Daniel Ozon, said the latest miner pulled out of the Zofiowka mine was pronounced dead after he had been trapped under some metal. He had worked for the company for 10 years.

More than 200 workers were involved in the rescue operation. Ozon said emergency workers were pumping air into the affected area to lower the level of methane gas before they can safely move ahead.

Adapt 2030 Ice Age Report: Are Hawaii eruptions and earthquakes related to cosmic ray increases?

With the strongest quake and volcanic eruption in on Hawaii Island, you need to ask yourself it is correlated to solar activity or has something to do with the intensifying grand solar minimum. A 6.9 earthquake and explosive eruption at the Pu O'o vent is rare, but looking at the intensity ramp up of the magnetic wave cancelling on our Sun, well the we get into some interesting similarities. I provide a timeline for the grand solar minimum intensification and incredible images of the lava events on the island.


Comment: Cosmic rays found to be a trigger for explosive volcanic eruptions. Another factor to consider is the slowdown in Earth's rotation:

Strong shallow 6.4 magnitude earthquake hits off the Philippines

chart
According to the latest reports by the US Geological Survey, an earthquake measuring 6.4 has struck off the coast of the Philippines.

The tremor was registered at 06:19 UTC (9:19 Moscow time). There are no immediate reports of casualties or damage from the quake, which hit at a depth of 30 km (18 miles), about 50 km north-northwest of Pandan, on the island of Catanduanes, according to the USGS.

No tsunami warnings were issued.

Seismological centers have posted the information about the earthquake on Twitter. Social media users are tweeting alleged photos/videos of the earthquake.

Powerful 6.9 magnitude earthquake, strongest since 1975, hits Hawaii's Big Island near erupting volcano

A powerful earthquake measuring magnitude 6.9 has struck just off the Big Island of Hawaii as numerous smaller jolts, including a 5.4 tremor, shook the island in the past hours, amid ongoing volcanic eruption.

The US Geological Survey has upgraded the severity of the earthquake off the Big Island in Hawaii to a 6.9 on the Richter scale, roughly an hour after it was registered. According to the new USGS data, the extremely powerful tremor was registered 16km southwest of Leilani Estates, Hawaii, at a depth of 5.0 km.

The quake struck on the south flank of Kilauea Volcano at 12:33 local time and was followed by several aftershocks, according to the National Weather Service, as eruptions at the volcano continue. No Tsunami warning has been issued.

The tremor was the most powerful of a series of earthquakes that have been rocking the islands over the past days. No Tsunami warnings have been issued after the quake.


Comment: The U.S. Geological Survey said the magnitude-6.9 was the largest Hawaii quake since the 1975 magnitude-7.1 earthquake, which killed two people. The two quakes were centred in almost exactly the same location. See also:

Fears Hawaii's Kilauea volcano will erupt at any moment following 250 earthquakes in the region in 24 hours

A series of earthquakes and the collapse of the crater floor at Hawaii's most active volcano

A series of earthquakes and the collapse of the crater floor at Hawaii's most active volcano could trigger an eruption, officials have warned. The lava lake at the summit of Kīlauea is one of several persistent on Earth. This image shows how it appeared on the evening of April 11
A series of earthquakes and the collapse of the crater floor at Hawaii's most active volcano could trigger an eruption at any moment, officials have warned.

Lava may burst through the ground east of Kilauea, one of five volcanoes on the US state's largest island, experts say.

The warning follows 250 seismic readings over the past 24 hours, with similar activity recorded prior to previous eruptions in the area.

In mid-April, an observatory issued a volcano activity alert when scientists noticed the Puu Oo vent was inflating and becoming pressurised.

The crater floor of the vent has since collapsed, and an 'intrusion' of lava was sent into a new area of the volcano which spread throughout last night.

Underground magma, which now flows beneath a main road and close to the residential district of Puna, could cause fatalities if it blows.

Ice cauldron in Bárðarbunga The volcano is hidden beneath the ice cap of Vatnajökull glacier.
The monster volcano Bárðarbunga, one of the most active and powerful volcanoes in Iceland and Europe, trembled yesterday afternoon. A sharp 3.9 magnitude earthquake was detected at 16:13 on Sunday afternoon, followed by a handful of smaller quakes.

The volcano has been relatively calm in 2018, with only a handful of 3+ magnitude quakes. The relative calm comes at the heels of relatively high levels of activity in 2016 and 2017. Since the largest earthquake to hit Bárðarbunga at the end of January, a 4.9 magnitude quake.

A 3.9 magnitude quake is considered a significant seismic event, as any quake in an active volcano which is larger than 3 on the Richter scale is considered a powerful quake. Quakes larger than 4 in volcanoes are relatively rare.
