Conjunction of the Moon and Jupiter.

Russian Meteor

Photograph of the hole in Chebarkul Lake made by Russian Meteor debris.

Scientists explained why telescopes could not see the Russian meteor. Astronomers could not trace the Chelyabinsk meteor because the celestial body was approaching from the Sun, and telescopes did not see it in the sunshine.

The meteor is the largest recorded object to strike the Earth in over 100 years.

Environment

The Coldest Village on Earth

A man passes a sign saying “Oymyakon ‘Pole of Cold'” on the site of a former meteorological station in the village of Oymyakon, in the Republic of Sakha, northeast Russia. The coldest temperatures in the northern hemisphere have been recorded in Sakha, the location of the Oymyakon valley, where according to the United Kingdom Met Office a temperature of -67.8 degrees Celsius (-90 degrees Fahrenheit) was registered in 1933 – the coldest on record in the northern hemisphere since the beginning of the 20th century.

Volcanos

Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): After the brief surge of activity during last week, the volcano has calmed down again to average levels.

Etna (Sicily, Italy): What started last night in fact evolved into a true paroxysm this time, with tall lava fountains and lava flows from the New SE crater. This is the first eruption of this kind after 9 months, and it will be interesting to see whether more follow (likely). The strombolian activity progressively increased and merged into lava fountains at around 04h40 local time. A lava flow descended into Valle del Bove and reached about 2600 m elevation on the slope north of Sierra Giannicola Picola. The eruption ended rapidly by about 06h30.

Etna parox

Shiveluch (Kamchatka): A possible ash explosion sent ash up to 16,500 ft (5.0 km) a.s.l. KVERT registered moderate seismicity, but clouds obscured the view of the volcano.

Tolbachik (Kamchatka): KVERT reports no changes in the ongoing eruption, that continues to produce lava flows from the southern fissure.

Ambrym (Vanuatu): Strong SO2 emissions are visible on today’s NOAA satellite data. This suggests that the lava supply to the lava lakes inside the vents remains strong.

Tongariro (North Island, New Zealand): An increased number of earthquakes and possibly a weak tremor pulses appear on today’s seismic recording.

White Island (New Zealand): Continuous tremor remains high (although a bit lower than a few days ago) and earthquakes have started to reappear. So far, no recent updates have been posted by GeoNet.

Santa MarĂ­a / Santiaguito (Guatemala): Relatively frequent small to moderate explosions have been occurring today. The activity generated ash plumes rising up to 1-1.5 km above the lava dome and drifting at 13,000 ft (4 km) altitude to the NW.

Fuego (Guatemala): The volcano has calmed down and is back to its typical activity with occasional mild strombolian explosions, generating ash plumes rising 5-800 m above the crater.

Copahue (Chile/Argentina): The volcano continued to show a gradually decreasing trend of internal activity, is the conclusion of the latest bulletin SERNAGEOMIN published. Weak seismic swarms continued to be registered mainly in the first week of February. A total of 331 seismic events were measured between 1-15 Feb. Degassing has been weak except on 5 Feb, when a gas plume rose significantly higher.

Storms and Floods

Tropical Cyclone Haruna located approximately 375nm west-southwest of Antananarivo, Madagascar – expected to track over southern Madagascar on Thursday.

18 Die in Storms in India

Unseasonal thunderstorms claimed 18 lives and damaged crops in southern India over the weekend.

The deaths were reported from nine of 23 districts in Andhra Pradesh state.

Most victims were killed by lightning strikes, collapsed houses and electrocution.

Strong gales damaged about 1 150 houses across four districts. Rain and hail damaged rice, maize and other crops over 252 500 hectares.
