Magnitude 5+ Earthquakes – Global

5.4 Earthquake hits San Juan, Argentina.

5.4 Earthquake hits near the east coast of Honshu, Japan.

5.3 Earthquake hits southern Sumatra, Indonesia.

5.3 Earthquake hits the Volcano Islands, Japan.

5.0 Earthquake hits the Balleny Islands.


The magnitude 7.2 earthquake that hit parts of Central Visayas last Oct. 15 moved part of Bohol closer to Cebu. The powerful quake – which left more than 200 people dead – moved Bohol, including Tagbilaran City, by 55 centimetres west towards Cebu. The phenomenon does not pose any threat to Cebu or Bohol however.

The tremor was generated by a blind fault, now called the North Bohol Fault. The movement was discovered through GPS (Global Positioning System) in Tagbilaran City. “This is normal, especially during a large quake.” The tremor has generated at least 4,026 aftershocks, 114 of which were felt.

Storms and Floods

Tropical Storms

In the North Indian Ocean:

Tropical Cyclone ‘Madi’ is stationary in the Bay of Bengal between Chennai, India, & Trincomalee, Sri Lanka.

Madi, in the Bay of Bengal, is expected to weaken gradually and move northwards slowly for 24 hours and then recurve towards west-southwest, the India Meteorological reported. The bulletin said that, under the influence of this system, rainfall would occur at a few places over coastal Andhra Pradesh and at isolated places over coastal Tamil Nadu and Puducherry and Andaman & Nicobar Islands during the next 48 hours.

Flooding in Libya

Flooding in Libya has claimed the lives of at least six people and damaged 400 houses.

Flooding in Brazil

Floods in Northeastern Brazil have claimed the lives of at least 11 people and left six others missing, Bahia’s Civil Defence emergency response agency said.

Heavy rainfall caused flooding in Lajedinho which destroyed some 70 houses and displaced around 200 people.

Brazil’s northeast is facing its worst drought in a century.

Flash floods and landslides are common in much of Brazil. Illegal construction, deforestation and unregulated housing has been blamed for devastating effects of the flooding in Brazil.

Following last Friday’s major winter storm that brought heavy snows and significant icing from Texas to Maine (“Cleon”), a new winter storm dubbed “Dion” followed a similar track on Sunday. The deadly winter storm kept a tight grip on much of the United States on Monday as cold, snow and ice spread across the East Coast. As much as 5 inches (12.7 cm) of snow were forecast for Monday night into Tuesday and much of the area from Virginia to coastal New England were under winter weather advisories.

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): The New SE crater has remained quiet over night, while tremor has risen a bit overall. The NE crater in turn shows intense degassing.

Klyuchevskoy (Kamchatka): Relatively strong ash emissions continue. This morning, the plume rose to about 27,000 ft (7 km) altitude, drifting NW.

Bagana (Bougainville Island, Papua New Guinea): New explosions occurred this morning. An ash plume rose to 10,000 ft (3 km) altitude this morning and drifted 20 nautical miles to the east (VAAC Darwin).

Sinabung (Sumatra, Indonesia): After a relatively calm period, a large vulcanian explosion occurred at the volcano this morning (04:30 GMT). VAAC Darwin reports an ash plume to 38,000 ft (12 km) altitude drifting 50 nautical miles to the NW. The eruption was preceded by a smaller one at midnight (GMT) with an ash plume altitude of estimated 18,000 ft (5.5 km). The volcano has been on red alert for 2 weeks and more than 17,000 people remain evacuated (for good reason!).
