Mayotte seismo-volcanic crisis: Significant subsidence detected, observation campaign launched
It's been almost a full year since the start of an intense earthquake swarm near the island of Mayotte and it seems we'll have some answers soon. While GPS stations show significant subsidence at the island, suggesting emptying of a nearby magma chamber, authorities launched several major observation missions at the end of February, with results expected within 6 months. The missions are coordinated by CNRS with the support of BRGM, IPGP, IGN, Ifremer and the Environment Ministry of France.

More than 1 600 earthquakes of magnitude 3.5 and more, about 50 km (31 miles) to the east of Mayotte, have been recorded since May 10, 2018. Of these, 29 earthquakes above magnitude 5 have been felt by the population across the archipelago and have affected buildings in some places.

Furthermore, low-frequency signals of a different type, which propagate more easily over long distances, have been recorded by global networks, in particular on November 11, 2018. These signals could correspond to seismic tremors, which are imperceptible earthquakes triggered by rising magma.

Since July 2018, moreover, regular signal processing by the permanent GNSS network run by the IGN shows that the six high-precision GPS stations on Mayotte have recorded a continuous eastward shift of around 14 mm/month (0.55 inches/month) or 168 mm/year (6.61 inches/year), together with subsidence at a rate of 7 mm/month (0.27 inches/month) or 84 mm/year (3.30 inches/year).

The rate of subsidence of the island prior to the swarm was just 0.0016 mm/month or 0.19 mm (0.0075 inches) per year.

This accelerating subsidence since the beginning of the seismic swarm caused Mtsangamouji to sink 6 cm (2.36 inches), Bandrele 10 cm (3.93 inches) and Petite-Terre 12 cm (4.72 inches).

Taken together, these observations suggest that this ongoing episode could be of the seismo-volcanic type.

The phenomenon could be explained by the emptying of a magma chamber located about 50 km (31 miles) east of Petite-Terre, at a depth of about 30 km (18.6 miles).

In response to a BRGM initiative at the start of this seismo-volcanic episode, the scientific community has been seeking to understand the phenomena and how they are evolving. In these circumstances, the CNRS coordinated a call for tenders to over 20 French research laboratories working in the relevant field, with the aim of improving scientific observations and understanding of the phenomenon and producing better estimations of the hazards and potential impacts for this French region.

This €420 000 effort will support ongoing observation missions by deploying instruments on land and at sea to produce data for immediate distribution to the scientific community. The call for tenders also covers data analysis and strengthening of the observation network.

Strong Earthquake Rocks Western Turkey

According to the European-Mediterranean Seismological Centre, the Western part of Turkey was hit by a 6.4-magnitude earthquake on Wednesday. At the moment there is no information about casualties or damage, caused by the quake.

The tremors started at about 06:34 GMT, with the epicentre located near the city of Acıpayam, 123 kilometres from the city of Antalya.

Powerful 6.3 Earthquake Hits Luganville, Vanuatu - USGS

Despite the strong earthquake that shook Vanuatu’s largest island, no tsunami warning has been issued so far.

A 6.3 magnitude quake struck 64 km east of Luganville on Espiritu Santo, the largest island in Vanuatu, on Wednesday, at a depth of 123 km, the US Geological Survey reported. No information about casualties or damage is available at the moment.

The epicentre of the quake was located at a depth of 125,4 km, the agency specified.

Magnitude 5.4 Quake Hits Sulawesi in Indonesia – USGS

MOSCOW (Sputnik) - A magnitude 5.4 earthquake struck the Indonesian island of Sulawesi on Sunday, the US Geological Survey (USGS) said.

The shallow quake was registered 30 kilometers (18.6 miles) northwest of the town of Pendolo. The epicenter lied at the depth of 10 kilometers (6.2 miles).

There were no immediate reports of casualties or damage. Indonesia is part of the so-called Ring of Fire, an area in the Pacific Ocean where the most active tectonic plates are located.

Earlier in the day the Xinhua news agency reported citing Thailand’s Department of Disaster Prevention and Mitigation that a tsunami alert was declared on Saturday in six provinces of Thailand after two earthquakes in the Indian Ocean.

Duchsinse is an unusual reporter of earthquakes and also volcanic activities in 3D graphic displays.

Reporting on 3/22/2019 he sees a quiet situation that he says means it is not good because to him it means pressure is building. The report covers activity on a global scale.

These activities have been talked about before in the sessions. I will give a sample session which goes into great detail but i will just give a small quote.

Session 22 August 1997:
Q: Okay. Now, we are onto the subject of our friendly local volcano down on Montserrat. What is it up to?

A: Seismic swarms... Much fear and concern by officials; muted...

Q: Can you give us an idea about what this volcano is going to do? What are the percentages in favor of a cataclysmic eruption in the near future?

A: Look to geologic map patterning for answer.

Q: What in particular should we be looking for?

A: Sequences, locators, historical telltale hints and signs. The signs always point the way for those who bother to read.

Q: Is there something about sequences of locators? Is it like a moving series in a general direction or pattern?

A: Yes.

Q: What general way does the sequence move? East to West? What?

A: Reverberatory.

Q: So, if something occurs in one place...

A: Like the wavelets in a small pool of water.

Q: Well, where does the stone drop?

A: Look to 18 degrees North and South.
I don't think the official reporting will be very anxious to let us know much.

March 28, 2019 - Magnitude 6.1 quake hits off Russia's Kuril Islands: USGS

A magnitude 6.1 quake struck off Russia's Kuril Islands, southeast of the Kamchatka peninsula, which lies on the earthquake-prone Ring of Fire, the U.S. Geological Survey said.

The epicenter of the quake, initially reported as a magnitude 6.5, was 168 miles (270 km) east of the small town of Severo-Kurilsk, the USGS said.

The quake struck at 10:06 a.m. on Friday (2206 GMT on Thursday). The area is sparsely populated.

Magnitude 6.5 Earthquake Hits Off Aleutian Islands - USGS

MOSCOW (Sputnik) - A 6.5-magnitude earthquake was registered off the coast of Kiska in the Aleutian Islands near Alaska on Tuesday, the US Geological Survey (USGS) reported.

The quake was registered at 21:35 GMT. The epicentre of the earthquake was located 31 kilometres (19 miles) to the northeast of the island at a depth of 19.1 kilometres (12 miles). No casualties or damages have been reported.

The Aleutian Islands with their 57 volcanoes form the northernmost part of the Pacific Ring of Fire, where a large number of earthquakes and volcanic eruptions occur.
