A 5.4-magnitude earthquake jolted Nicaragua yesterday, killing a woman and damaging homes close the epicentre in the country's north, officials said.

The quake struck at 10:48am in the area between the El Hoyo and Momotombo volcanoes, at a shallow depth of 2.9km.

The woman, Higinia Margarita Cruz, suffered a heart attack from the shock of the shaking, said First Lady Rosario Murillo, who is also the government spokeswoman.

Cruz was 78.

Windows shattered in a building under construction in Puerto Momotombo and many homes sustained damage to roofs.

Startled locals ran outside their homes and stayed there, concerned that if they went inside, another quake might strike.

Magnitude 5 earthquake hits Kalamata on Greek coast

Earthquake Kalamata 29th September 2016

Kalamata, Greece
An earthquake measuring 5 points on the Richter scale shook Kalamata on Wednesday morning, bringing memories of the 1986 tremors that killed 22 people.

The tremors were felt in Kalamata at 10:17 am, while several towns and villages in southwestern Peloponnese felt the effect. According to seismologists, the epicenter of the earthquake was in the Messinian Gulf sea, 14 kilometers south of Kalamata and had a depth of 19 kilometers.

Meanwhile, just before midnight tremors measuring 5.4 points on the Richter shook the islands of Dodecanese, mostly felt in Rhodes. However, seismologists said on Skai radio that the two earthquakes are not related.

Comment: The U.S. Geological Survey also reported 2 other earthquakes in a 24 hour period measuring above magnitude 4 in the regions of Greece and Turkey.

3.9 magnitude earthquake at Katla Volcano, Iceland

An earthquake of magnitude 3.9 hit Mýrdalsjökull glacier at 1:30 pm today, mbl.is reports. A few aftershocks have registered, but there is no sign of volcanic activity in the area, according to the Icelandic Met Office.

The source of the quake was the south side of the Katla volcano caldera, which is under the ice cap of Mýrdalsjökull glacier. The area is being monitored day in and day out by the Icelandic Met Office.

There was less seismic activity in Mýrdalsjökull glacier last week than during the previous week. On August 29, two earthquakes of magnitude 4.5 registered in the northern part of the Kaltla volcano caldera. Those were the largest quakes to hit the area since 1977.

Swarm of 100+ earthquakes hit Salton Sea, California

A magnitude-4.3 earthquake hit in the Salton Sea area on Sept. 26, 2016.
More than 100 small earthquakes — including three of a magnitude greater than 4 — struck the Salton Sea area Monday.

According to the U.S. Geological Survey, the swarm of quakes started early Monday morning and continued into the evening. Quakes measuring 4.3 and 4.2 magnitude occurred Monday night.

Many of the quakes were centered near Bombay Beach. They were felt in a relatively small area around the Salton Sea, according to the USGS.

Swarms of small to moderate earthquakes are fairly common in the area. In 2009, the Salton Sea saw a swarm of more than 200 small quakes.

The sea sits atop a very thin crust that is being constantly stretched as the North American and Pacific plates grind against each other. The area is also veined by dozens of faults — most notably the San Andreas -- that run parallel to and crisscross one another.

Scientists believe that because of the thinness of the crust, hotter material can get closer to the surface and cause temblors.

Seismologist Lucy Jones said on Twitter on Monday night that magnitude 4 quakes near the San Andreas "increase the chance" of a big quake "a little bit. But we have swarms without big [earthquakes] — most likely nothing more will happen."

Shallow 4.6 earthquake recorded off Oregon coast near Brookings; second for the region in 5 hours

A pair of moderate earthquakes rattled the coast of Southern Oregon and Northern California late Saturday evening and early Sunday morning, according to the U.S. Geological Survey.

A magnitude 5.0 quake occurred in the Pacific Ocean nearly 100 miles off the coast of Gold Beach, Oregon, around 10:01 p.m. Saturday. A magnitude 4.6 quake rumbled nearly 100 miles off the coast of Brookings, Oregon, nearly five hours later.

The first quake occurred about 6.2 miles down in the ocean floor. The second earthquake occurred further down, about 10 miles beneath the Earth's surface.

Neither of the quakes prompted tsunami advisories for coastal communities, according to the National Weather Service's Tsunami.gov.

While both of these quakes were moderate in strength, news of an earthquake near Oregon is always sure to spark interest as the scientific community has become more aware of a pending Cascadia Subduction Zone earthquake. The fault, which lies just off the coast of the Pacific Northwest, is long overdue for a massive earthquake, according to experts. Many predict it could be as strong as a magnitude 9.0 when it eventually hits (this video explains the significance of that number).
