WORLDWIDE EARTHQUAKE REPORT JANUARY 18_2024
High levels of seismic activity occurred in the past 24 hours. A M6.4 earthquake shook the Tonga region in the southwest Pacific Ocean. An event of such magnitude was to be expected due to the M5+ seismic clustering that occurred in previous days. There is a relationship between seismic clustering and significant M6+ events.
A seismic cluster of 4 earthquakes M5+ occurred in the southwestern Pacific Ocean, between the islands of Vanuatu and northeastern New Zealand. These earthquakes could be a significant event in the region.
The epicenter was located about 126 km (78 miles) NW of Fangale’ounga, and 126 km (78 miles) WSW of Neiafu, Tonga. 21 000 people are estimated to have felt light shaking. The USGS issued a Green alert (low) for shaking-related fatalities and economic losses. The M6.4 earthquake was preceded by an M5.0 and an M5.8 earthquake.
M5.3 and M5.7 earthquakes shook the South Sandwich Islands. This seismic activity takes pressure off Chile, which so far has recorded light M4+ and M5+ activity.
On the morning of January 18, Mexican authorities recorded an M5.0 earthquake with epicenter 21 km southeast of Crucecita, Oaxaca, at 08:40 hours local time. Fortunately, the earthquake did not cause any damage.
An M4.7 earthquake struck at the top of the world. According to information from Volcanodiscovery: "The earthquake was the strongest to hit this part of Russia in over 6 years. Earlier, the last quake of equal or greater strength near the present epicenter had been a magnitude 4.8 earthquake on Tuesday, Jul 17, 2018"
The total number of earthquakes recorded in the last 24 has decreased to 838 which is within the normal range of activity. According to
Volcano earthquake report volcano earthquake swarm occurred in:
Campi Flegrei (Phlegrean Fields) (11 quakes between mag 0.1-1.3),
Clear Lake (33 quakes between mag 0.2-1.7),
Etna (8 quakes between mag 1.1-2.4),
Krísuvík (20 quakes between mag 0.1-1.6),
Reykjanes (22 quakes between mag 0.1-2.1)
The strongest volcano earthquake occurred in
Cuernos de Negros volcano with a M3.0 located 16 km west of Dumaguete City, Philippines.
