Magnitude 5+ Earthquakes – Global

5.1 Earthquake hits offshore Coquimbo, Chile.

Japan – The coastline of northeastern Japan that dropped by more than 3 feet during the 9.0 magnitude Fukushima quake in 2011 is now rising steadily.

The tectonic thrust also shifted the coast eastward 18 feet as it generated a tsunami that ravaged coastal areas. But satellite observations show that one spot on the Oshika Peninsula in Miyagi Prefecture has risen by 1.3 feet since measurements were taken the day after the 2011 temblor.

Other locations have seen lesser, but significant, rises.

Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

Gl sst mm

In the South Indian Ocean: Tropical cyclone (tc) 11s (Eleven), located approximately 715 nm east-northeast of Port Louis, Mauritius, is tracking southward at 14 knots.

Tropical cyclone 09s (Enawo) has re-generated as a tropical cyclone and is located approximately 434 nm southeast of Europa Island, is tracking south-southeastward at 22 knots.


New Zealand – Continuing torrential rainfall created widespread flooding in the Waihi and Whiritoa areas. The small community of Whiritoa woke up yesterday morning isolated after several slips on State Highway 25 either side of the beachside settlement left a number of people stranded in vehicles.


Turtle Disease Mystery

Turtles in Australia’s Great Barrier Reef have suffered from a variety of illnesses that some experts believe may be caused by cobalt pollution.

The first outbreak began in 2010 when two-thirds of the green turtles examined in Brisk Bay developed a herpes virus infection that caused tumours to grow on their eyes, shells, tails, flippers and organs. Two years later, 100 green turtles washed up onshore at nearby Upstart Bay, suffering seizures and uncontrolled head movements that led to a mass death.

The latest ailments have recently left some of Upstart Bay’s turtles with mysterious eye infections.


Global Temperature Extremes

The week’s hottest temperature was 110.0 degrees Fahrenheit (43.3 degrees Celsius) in Port Hedland, Western Australia.

The week’s coldest temperature was minus 74.0 degrees Fahrenheit (minus 58.9 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.


Wildfires – Thailand

Authorities reported that a total of 243 bush-fire incidents were reported during the period from February 15 until March 8 with 7,447 rai of forest being destroyed.

Tak province reported the highest bush fire incidence with 64 incidents and 3,452 rai of forest being destroyed. The other bus fire incidents were reported in Lampang, 51 incidents and 1,558 rai of forest destroyed; Phrae, 39 incidents with 662 rai destroyed; Chiang Mai, 32 incidents with 389 rai destroyed; Lamphun, 25 incidents with 652 rai of forest destroyed; Phayao, 11 incidents with 260 rai destroyed; Nan, 9 incidents were 335 rai destroyed; Mae Hong Son, 8 incidents with 61 rai destroyed and Chiang Rai, 4 incidents were 58 rai destroyed.

However, they said that bush-fire incidences this year were less than that of the previous years during the same period, thanks to public campaign for local villagers to refrain from starting bush fires, creation of networks to control bush fires and adoption of preventive measures such as fire prevention trenches and installation of fire alarm system.


Roundup of Global Volcanic Activity – Ongoing Activity for the week of 1 March-7 March 2017

Bagana | Bougainville (Papua New Guinea) : Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that during 4-5 and 7 March ash plumes from Bagana rose to altitudes of 2.1-2.4 km (7,000-8,000 ft) a.s.l. and drifted 65 km W and SW.

Bogoslof | Fox Islands (USA) : AVO reported that no significant volcanic activity at Bogoslof had been detected in seismic, infrasound, or sometimes cloudy satellite data during 1-7 March. The Aviation Colour Code remained at Orange and the Volcano Alert Level remained at Warning.

Bulusan | Luzon (Philippines) : PHIVOLCS reported that a weak phreatic eruption at Bulusan occurred at 1357 on 2 March. The event was recorded by the seismic network as an explosion-type earthquake followed by short-duration tremor that lasted approximately 26 minutes. Visual observations were obscured by weather clouds, although a small steam plume rising from the SE vent was recorded by a webcam. The Alert Level remained at 1, indicating abnormal conditions and a 4-km-radius Permanent Danger Zone (PDZ).

Cleveland | Chuginadak Island (USA) : AVO reported that during 1-4 and 6-7 March slightly elevated surface temperatures were identified in satellite images of Cleveland, along with minor steaming from the summit visible in clear webcam images during 1-3 March. Cloud cover prevented views on 5 March. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that during 1-3 and 5-6 March ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted SW, S, SE, and E.

Ebeko | Paramushir Island (Russia) : KVERT reported that, according to observers in Severo-Kurilsk (Paramushir Island) about 7 km E, explosions at Ebeko on 24, 26, and 27 February and 2 March produced ash plumes that rose as high as an altitude of 2.5 km (8,200 ft) a.s.l. The Aviation Colour Code remained at Orange (the second highest level on a four-colour scale).

Kilauea | Hawaiian Islands (USA) : During 1-7 March HVO reported that the lava lake continued to rise and fall, circulate, and spatter in Kilauea’s Overlook vent. Webcams recorded incandescence from long-active sources within Pu’u ‘O’o Crater, from a vent high on the NE flank of the cone, and from a small lava pond in a pit on the W side of the crater. The 61G lava flow, originating from a vent on Pu’u ‘O’o Crater’s E flank, continued to enter the ocean at Kamokuna. Surface lava flows were active on the coastal plain, along the E side of 61G, about 500 m upslope of the FEMA emergency road. Other surface flows above the pali appeared during 1-2 March.

Manam | Papua New Guinea : Based on a pilot observation, the Darwin VAAC reported that on 3 March an ash plume from Manam rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted N.

Nevado del Ruiz | Colombia : Based on satellite images, the Washington VAAC reported that on 4 March an ash plume from Nevado del Ruiz rose to an altitude of 7.6 km (25,000 ft) a.s.l. and drifted over 31 km NW.

Sabancaya | Peru : Based on webcam images, satellite views, and seismic data the Buenos Aires VAAC reported that during 1-4 and 6-7 March sporadic gas-and-ash puffs rose from Sabancaya. Weather clouds often hindered observations of the volcano. On 3 March ash plumes rose to altitudes of 9.1-10.4 km (30,000-34,000 ft) a.s.l. and drifted W, SW, and S. Intermittent increases in seismicity were also detected that day.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that during 24 February-3 March lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions, and hot avalanches. Explosions on 24 February generated ash plumes that rose to an altitude of 5 km (16,400 ft) a.s.l. and drifted E. Satellite images showed a daily thermal anomaly over the dome, and ash plumes that drifted 95 km NE during 25-26 February. The Aviation Colour Code remained at Orange.

Sinabung | Indonesia : Based on PVMBG observations, satellite data, webcam images, and wind data, the Darwin VAAC reported that during 1-2, 5, and 7 March ash plumes from Sinabung rose to altitudes of 3-4.3 km (10,000-14,000 ft) a.s.l. and drifted N, NW, W, and SW.

Suwanosejima | Ryukyu Islands (Japan) : Based on JMA notices and satellite-image analyses, the Tokyo VAAC reported that during 3-4 March explosions at Suwanosejima generated ash plumes that rose to altitudes of 1.5-1.8 km (5,000-6,000 ft) a.s.l. and drifted SE
