Taiwan Struck by Two Earthquakes

On Wednesday, March 23, two earthquakes struck southeastern Taiwan. The earthquakes shook buildings in Taipei, the capital of Taiwan, but there were no reports of damage. The two earthquakes happened in quick succession, with the strongest one having a magnitude of 6.6, the deepest one having a depth of 30.6km, and the other having a 19.3km depth. Both quakes were felt across the country with the epicenters in Hualien county just offshore and close to the city of Taitung. Both Hualien and Taitung are highlands with many mountains so not many people live there.

Many earthquakes have occurred in Taiwan in the past because it lies near the junction of two tectonic plates which makes it very prone to earthquakes.

Update on Tectonic Activity in the Sao Jorge

Last week, Sao Jorge, part of the Azores Archipelago, has experienced thousands of tremors in the past month since the beginning of the crisis (reported to be 27,626 as of 4/6).  On Wednesday of last week (4/6), it was reported that Sao Jorge had experienced volcanic-tectonic tremors, which refer to earthquakes caused by a movement of magma.  However, it was stated that the volcanic-tectonic tremors did not mean a volcano was inevitable. Currently, an emergency plan has been implemented, which includes an evacuation plan and allocating of necessary resources to the island.

Powerful 5.2 Magnitude Earthquake Hits Eastern Turkey

A 5.2 magnitude earthquake struck eastern Turkey today, April 9, 2022. The town of Puturge in the Malatya province was the epicenter of the recorded tremor at 5:02 pm. The depth of the earthquake was 6.7 kilometers below the surface. Turkey sits on a fault line so earthquakes and movement are not new to the country. At this time no casualties or injuries have been reported.

Earthquake Hit Europe’s Supervolcano Campi Flegrei

On March 30, 2022, an Earthquake of 3.6 magnitudes was recorded at the supervolcano Campi Flegrei. Campi Flegrei is one of the world’s most populated active volcanoes. 2.2 million people live within three miles of the volcano. This was not the first time an earthquake hit the volcano, the site experienced its largest earthquake with a magnitude of 4.2 in 1984. The volcanic activities at Campi Flegrei relate to the convergence of the African Plate and the Eurasian plate. Since the March 30 earthquake, scientists have advised mitigation because while the earthquake does not mean an eruption is imminent it could mean there will be one at some point in the future. If the volcano erupts, models show that it could produce a 100-foot tsunami that would severely impact coastal areas like Pozzuoli and Sorrento.

Increase In Seismic Activity in Sao Jorge

Sao Jorge, one of the Azores islands off the coast of Portugal, is having an increase in seismic activity, which has prompted an evacuation.  The area has experienced an abundance of smaller earthquakes recently, which has led many to be wary of a potential eruption from nearby volcanos.  It has been stated that an eruption could or could not happen, but the authorities are still taking precautions for the worst case.

7.4 Magnitude earthquake strikes Japan killing 4 and injuring over 100

On March 16th a deadly earthquake struck Fukushima in Northern Japan, the same region devastated by the 2011 earthquake and tsunami. In comparison Wednesdays quake had a magnitude of 7.4 in comparison to 2011’s 9.1. Although tragic, Wednesdays death toll stands at 4 people and a tsunami wave height of 8 inches as compared to 22,000 killed in 2011 and 30 foot high tsunami waves. This is in spite of the two quakes epicentres being within 55 miles of each other.

Disruption however was far spread, 78 people where trapped in a derailed bullet train In Fukushima having to wait hours for rescue. The Japanese meteorological society has also issued mudslide alerts in the region. However more disruptive is the 6 Thermal power plants that have been taken out of operation, some with damage that could leave them idle for months. The national government is calling for people to cut back on power consumption warning of power cuts and blackouts similar to those that followed the Wednesday quake. However temperatures have been recorded as low as 2 degrees celsius in Tokyo placing an increasing pressure on the limited power grid.

Using cell phone GNSS Networks to monitor crustal deformation

It has been discovered that using The Global Navigation Satellite System or GNSS, that is used by a Japanese phone carrier, could be used to enhance monitoring of crustal deformation. These systems are installed at cell phone base stations and can “Rival the precision of data from a government-run GNSS network, while providing more complete geographic coverage.”
