Things are heating up in Iceland ?
1 Aug 2022

Apparently yesterday's earthquake was indeed a M 5.4 earthquake. German Vulkane.net writes following today:

Swarm quake under Reykjanes on 01 Aug 2022
1 August 2022 by Marc Szeglat



Earthquake activity under Reykjanes remains strong

After some confusion about the strong earthquake Mb 5.4 last night, I summarise the events of the last hours here again.

The swarm quake that began on Saturday morning continues and has lost none of its force. There are different accounts as far as the number of earthquakes is concerned. The IMO tables show 3172 tremors so far. 99 earthquakes had magnitudes from 3. According to an IMO statement, even more than 5,500 earthquakes were registered. This puts the swarm quake in the top range of all comparable events that I have been allowed to report on in Iceland so far. The strongest earthquake of the swarm so far manifested itself yesterday afternoon, at 17:47:59 UCT. It had a magnitude of 5.4. The earthquake focus was located at a depth of 1.9 km. The epicentre was located 3.0 km east-northeast of Grindavík.



The earthquake was felt in large parts of southwest Iceland. Perception reports were received from the Snæfellsnes Peninsula. In Reykjavík, crockery clanged in the cupboards. In Grindavik itself, a water pipe was damaged. Items fell from shop shelves.

Automatic system failed

The automatic system of earthquake recording failed and a number of corrections were necessary until the final values were established. In the meantime, there were some error messages, which also indicated earthquakes with magnitudes greater than 3 at various locations in Iceland. Among them was a supposed M 4.4 quake under Katla. These quakes did not occur. Instead, there were several earthquakes in the magnitude 4 range at night, which occurred in the west of the Reykjanes Peninsula.

Magmatic activity under Fagradalsfjall

There seems to be no question that the earthquake swarm was triggered by magma intrusion in the area of the Fagradalsfjall volcano. This changed the stress field and triggered earthquakes in neighbouring fault systems. It is not yet clear to what extent ground uplift will occur as a result of the magma intrusion. The display of the automatic GPS measurements has been suspended. We will probably have to be patient until the IMO scientists come out with new verified data.

Since the beginning of the year, there has been significant ground uplift in a system that lies a good 10 km west of Fagradalsfjall. The situation was similar before the Fagradalsfjall eruption last year. Apparently, the magmatic activity has now shifted back to Fagradalsfjall and the risk of an imminent volcanic eruption is clearly increasing. On the livecam, rockfalls could be observed at the Fagradalsfjall cone, and steam was generated at the base of the cone.

▪︎Earthquake swarm. In less than 24 hours 1,200 quakes recorded in volcanic area on Ecuador-Colombia border

A report from the Geophysical Institute, says that the 1200 light earthquakes that are of volcanic tectonic character occurred in the area of the Chiles-Cerro Negro volcanic complex on Saturday, July 30, 2022.

The last study of the IG specifies that the superficial activity in the Chiles volcano is "very low" and with an "ascending" inclination, while the internal activity is "moderate" but also ascending.
Last Tuesday, the Geophysicist warned of an increase in the activity of the volcanic complex and asked the authorities of Ecuador and Colombia to consider a joint evacuation drill as a "preparedness measure".

According to the IG, an inflation phenomenon in the massif plus a fault considered "seismogenic" in the area, in addition to other conditions, could have acted as a "triggering mechanism" for the strong earthquake of magnitude 5.7 last Monday.

Reykjanes Península earthquake swarm update

A powerful earthquake swarm has begun on the Reykjanes Peninsula, Iceland. Nearly 4000 earthquakes have been detected in the first 24 hours, with the activity continuing at a strong pace. First data also shows tremor signals, indicating that the activity is likely due to magma movement below the ground.

This has prompted the officials to raise the alert level in the area. An eruption is likely, with the chance increasing steadily as the earthquake activity continues.

The image below shows the spreading tectonic plates and where the Mid-Atlantic Ridge passes through Iceland. It enters the southwest on the Reykjanes Peninsula, going to the east and turning north. Red triangles show the main central volcanoes.

A strong burst of nearly 4000 earthquakes occurs in Iceland, causing an increased risk of a new volcanic eruption as we head into August

Iceland is on alert again, due to moving magma causing thousands of earthquakes to swarm the Reykjanes Peninsula, increasing eruption risk

Another earthquake Mb 5.0 shakes Iceland



The earthquake swarm under Reykjanes continues. There are phases in which the activity seems to weaken somewhat, only to intensify again shortly afterwards. We have seen such fluctuations in comparable events before. Last night around 11 pm, the activity increased again. Its focus shifted towards Lake Kleifarvatn. An earthquake of magnitude 5.0 occurred there tonight at 2:27 a.m. The quake was clearly felt in the southwest of the country. There were 2 other relatively strong earthquakes with magnitudes 4.8 and 4.7. A total of 15 events of magnitude 4 were recorded, extending from Mount Þorbjörn to Lake Kleifarvatn. IMO's tables show 3364 quakes for the last 48 hours.

As far as one can trust the GPS data, no ground uplift is registered, but a weak ground subsidence. Instead, there is divergence along the magmatic vein at Fagradalsfjall. Nevertheless, Icelandic researchers seem to agree that the seismic crisis is caused by the intrusion of a magmatic vein. The magma intrusion triggers the stronger earthquakes along the Reykjanes fault zones, but these are not volcanotectonic earthquakes. In a newspaper interview, geophysicist Páll Einarsson clarifies that the strong earthquakes are not directly caused by the rising magma and that these earthquakes do not allow any conclusions that a strong eruption must necessarily occur.

In fact, it is not yet clear at this point whether an eruption will actually occur. The magmatic duct can still get stuck in the earth's crust. But the longer the quakes continue, the greater the probability of an imminent volcanic eruption.

There is an increased risk of rockfalls on the Reykjanes Peninsula. A number of rockfalls have been reported in the region. IMO recommends being cautious on steep slopes and near sea cliffs and avoiding areas where rocks may fall.

EARTHQUAKE REPORT PAST 24HRS

More than 100 earthquakes shake Puerto Rico, from August 05 to 09, 2022, reports the United States Geological Survey (USGS).

More than 100 earthquakes have struck Puerto Rico and surrounding areas in recent days; fortunately, there is no tsunami threat at this time.

The latest quake occurred at 13:07 on August 9 and had a magnitude of 3.3 with a depth of 16 kilometers, the USGS said.

Of the 110 earthquakes that struck the area in the last week, 13 occurred in the last 24 hours, and most were concentrated in southwestern Puerto Rico, according to the USGS.

These earthquakes are not far from the epicenter of a strong earthquake that occurred in January 2020. That 6.4 created extensive damage in Puerto Rico, including widespread power failures across much of the island. A swarm of earthquakes began here in December 2019 and unrest has continued since then.

These earthquakes are occurring near the northern edge of the Caribbean Plate, a mostly oceanic tectonic plate that underlies Central America and the Caribbean Sea off the northern coast of South America. The Caribbean Plate is bordered by the North American Plate, the South American Plate, the Nazca Plate and the Cocos Plate. The edges of these plates host continuous seismic activity, including frequent earthquakes, occasional tsunamis and sometimes even volcanic eruptions. Fortunately, the earthquakes so far have been moderate enough not to create a tsunami. The strongest, a 3.1 that struck last night, was not strong enough to generate a tsunami threat for Puerto Rico, the Bahamas, the Caribbean or the U.S. East Coast.

Balloon fleet detects 7.3 magnitude earthquake from the stratosphere

A new paper just published in the Geophysical Research Letters reports the detection of a magnitude 7.3 earthquake by a fleet of balloons floating through the stratosphere above Indonesia's Flores Sea. Onboard infrasound sensors registered acoustic waves rippling upward from the sea surface below, proving that, here on Earth, balloons can be used as seismometers.

In the fall of 2021, the Centre National d’Etudes Spatiales (CNES) launched a fleet of 16 balloons from Mahé Island in the Seychelles archipelago. Unlike ordinary weather balloons, which explode in a matter of hours, these were "superpressure balloons," which can remain aloft for months. Stratospheric winds carried them over the Flores Sea.

Four balloons picked up the undersea quake on Dec. 14, 2021. Combining their signals, researchers pinpointed the epicenter within 300 km, the magnitude of the quake within 0.8 units, and its onset within 50 seconds. Furthermore, waveforms recorded by the infrasound sensors were detailed enough to sense structures in the Earth 100 km deep.

"Balloons could be used to cover ocean regions where conventional seismometers are not yet deployed," notes Garcia. "Another advantage: Balloons may be rapidly deployed just after a big quake for monitoring aftershocks."

The test flights have already unearthed a curiosity in South America. On Nov. 28, 2021, just one of the balloons detected a magnitude 7.5 earthquake in northern Peru. The infrasound frequency, 0.23 Hz, was higher than expected; for comparison, the Flores Sea quake registered a more typical 0.085–0.125 Hz. Garcia's team believes the high pitch may have been caused by a "ringing" of sediments in the Amazonian basin.

Sensing earthquakes from the stratosphere is relatively new. Researchers at Caltech and the Jet Propulsion Laboratory did it for the first time in July 2019. Garcia's study marks the first time an earthquake was detected by more than one balloon. It won't be the last.
