Increased seismic activity near Kick 'em Jenny underwater volcano

Grenada's National Disaster Management Agency (NaDMA) has noted an increase in seismic activity near the Kick 'em Jenny underwater volcano.

In an update shared June 14, 2020 via social media, NaDMA said it received technical advice from the monitoring team at the University of the West Indies Seismic Research Centre St Augustine Campus Trinidad and Tobago (UWI SRC), showing increased seismic activity at the Kick 'em' Jenny Volcano.

The latest activity was observed over a seven-day period in the month of June.

"Though the Alert level remains at YELLOW, which is a 1.5 km exclusion zone around the summit of the volcano. However, with the increased activity, the Agency encourages marine operators to be vigilant when traversing the area, as increased seismic activity also results in the emission of gases, which can reduce the density of the water around the summit."

Weakening of Earth's magnetic field probed

Geophysicists have been puzzling over a gradual weakening of the Earth's magnetic field in an area stretching from Africa to South America, which has resulted in technical disturbances in satellites orbiting Earth.

Scientists have resorted to data from the European Space Agency's (ESA) Swarm constellation to probe the disturbing weakening of Earth's magnetic field in the area known as the "South Atlantic Anomaly".

Jurgen Matzka, from the German Research Centre for Geosciences, and a team of experts from the Swarm Data, Innovation and Science Cluster (DISC) have been using data from ESA's Swarm satellite constellation to identify and measure the different magnetic signals that comprise Earth's magnetic field.
"The new, eastern minimum of the South Atlantic Anomaly has appeared over the last decade and in recent years is developing vigorously. We are very lucky to have the Swarm satellites in orbit to investigate the development of the South Atlantic Anomaly. The challenge now is to understand the processes in Earth's core driving these changes," said Matzka.

A magnitude 6.0 earthquake struck off the coast of northeast Taiwan at 4:19 a.m. this morning (June 14), according to the Central Weather Bureau (CWB).

The epicenter of the temblor was located 85.3 kilometers southeast of Yilan County Hall at a focal depth of 54.8 km, according to CWB data. Taiwan uses an intensity scale of 1 to 7, which gauges the degree to which a quake is felt at a specific location.

The quake's intensity registered as a 3 in Yilan County, Hualien County, Nantou County, Hsinchu County, Taitung County, Yunlin County, and Chiayi County. An intensity level of 2 was registered in Taipei City, Taoyuan City, Keelung City, Taichung City, New Taipei City, Miaoli County, Changhua County, Chiayi City, Kaohsiung City, and Tainan City.

A lesser intensity of 1 was felt in Hsinchu City, Pingtung County, and Penghu County. No injuries resulting from the quake had been reported at the time of publication.

6.7 magnitude earthquake near the southern Japanese islands of Ryukyu.
A 6.7 magnitude earthquake has occurred at sea, near the southern Japanese islands of Ryukyu. So far, no tsunami warning has been issued. A powerful tremor was detected off the coast early on Sunday, the country's weather agency said. The epicenter is estimated to be around 160 km below the surface.

Despite the depth, the quake was felt in Okinawa, as well as Japan's southernmost main island of Kyushu, according to local media. No information on possible damage or casualties was immediately available.

On Monday afternoon, the capital city of India witnessed yet another low-intensity earthquake. The National Center for Seismology revealed the epicentre of the earthquake was near Gurgaon, Haryana, and its depth was recorded to be 19 km with a magnitude of 2.1. Mild tremors were reportedly felt in Delhi, Noida, and the surrounding areas for a few seconds.

Just a week ago, on June 3, Delhi NCR had witnessed another earthquake of magnitude 3.2 on the Richter scale, which struck 19 km southeast of Noida. Further back, on May 29, an earthquake measuring 4.6 on the Richter scale jolted the NCR.

Since April 2020, New Delhi and nearby areas have recorded more than 14 earthquakes. According to the National Center for Seismology, all these earthquakes fell into the range of low to medium, as their magnitude was less than five.

This phenomenon, involving a collection of related earthquakes focused on a particular area for a limited period, is called 'swarm' activity. The swarm activity may or may not have an apparent triggering event behind it: say a large earthquake or a huge landslide.
