Over 500 earthquakes in Reykjanes swarm

The swarm of earthquakes that originate in Fagradalsfjall mountain on the Reykjanes peninsula are now on the decrease. A few earthquakes occurred yesterday morning but they’re diminishing.

According to the Iceland Met Office, over 500 earthquakes have been measured in the swarm which began Wednesday morning at 7 am. Three earthquakes were clearly felt in Reykjavik, especially the one at 13:55 which measured 4.1.

Geophysicist Páll Einarsson said speaking to today’s Morgunblaðið that the earthquakes are at the point where the tectonic plates meet. He said that although earthquakes in Reykjanes are common, the swarm yesterday was one of the biggest that they’ve measured in a few years.

Tropical depression 12w (Twelve), located approximately 220 nm south-southeast of Hong Kong, is tracking westward at 08 knots.


Ghana – Ghana has been hit by deadly floods in the northern region. Most areas of the regional capital, Tamale got flooded after heavy rains on Tuesday flooded major areas. Local media reported two deaths and the loss of properties.

Philippines – Heavy rains battered parts of the Philippines Thursday, July 27 due to southwest monsoon enhanced by a severe tropical storm. The country’s weather bureau said this year’s seventh cyclone ‘Noru,’ locally known as ‘Gorio,’ has intensified into a severe tropical storm. ‘Gorio’ is not expected to make landfall, but Batanes in northern Luzon is now placed under warning signal number one. Western Luzon has been damped with moderate to occasional heavy rains. The rest of Luzon and parts of the Visayas region have been affected as well. Many roads were impassable due to persisting floods. Floods in some parts of Quezon City are waist-deep. The weather has prompted dozens of cities and provinces to suspend classes in all levels of public and private schools.

Istanbul, Turkey – At least ten people were injured – two of them seriously – when a violent thunderstorm struck Istanbul, bombarding the city with hailstones the size of golf balls and submerging much of the city in knee-deep water. he unforgiving winds, rain and hail appear to have worn away the paint on the Turkish Airline jet’s nose, with cracks visible on the pilots’ window. he plane was forced to make an emergency landing in the Aegean city of Canakkale, around 170 miles flight from Istanbul which endured the worst of the freak storm.

Wildfires – Portugal

Portugal’s Civil Protection Agency says firefighters have brought under control a major 5-day-old wildfire that blackened a wide area of pine and eucalyptus forest.

The blaze at Serta, about 200 kilometers (125 miles) northeast of Lisbon, is believed to have charred more than 25,000 hectares of woodland.

Other fires broke out Thursday, however, amid continuing hot and windy weather. The Weather Institute says more than 70 percent of Portugal is experiencing severe drought conditions. The Civil Protection Agency reports it has deployed more than 1,100 firefighters and 23 water-dropping aircraft to 13 blazes. Ten villages had already been evacuated after fires broke out on Sunday. By about midnight last night the fires had reached Macao, a town with a population of 2,000.


Sizzling Shanghai, China

Shanghai registered on July 21 its hottest day since records began in 1872 as a stubborn heat wave baked much of China. The new record of 40.9 degrees Celsius (106 F) broke the previous record of 40.8 set in 2013.

Chinese meteorologists say Shanghai is getting hotter, with eight of the 12 highest temperatures over the past century occurring during the past five years.

Shanghai’s weather bureau blamed the heat on a stubborn subtropical high and southwesterly winds that are predicted to last until early August. That’s when the typhoon season typically arrives in eastern China.

Atomic Paradise

Even though it’s still unsafe for people to live on Bikini Atoll, marine life is thriving 60 years after a series of 23 atomic blasts left it saturated with radiation.

Scientists from Stanford University say coconut crabs, coral and other species that have managed to re-emerge on Bikini show barely any genetic differences from those living in uncontaminated parts of the Pacific.

Lead researcher Stephen Palumbi believes that at least the coral have mechanisms to protect their genetic information from radiation.

Global Warming

Climate change drawing squid, anchovies and tuna into UK waters

Squid and anchovies, more commonly eaten by Britons holidaying abroad, are being drawn into UK waters in large numbers by climate change, according to major new report that suggests the nation’s long-lost bluefin tuna is also returning.

However, global warming is harming sea birds, such as puffins, fulmars, terns and razorbills, as the fish they rely on are driven north or deeper as waters warm. The analysis of the impact of climate on the UK’s seas, which draws on the work of 400 scientists, found a steady rise in water temperature.

It also found a clear rising trend in sea level, leading to much more frequent extreme high water events. Improved defences and forecasting have prevented an increase in coastal floods, but the report warns that sea level rise around the UK is likely to accelerate.

Squid were seen in the North Sea only occasionally in the past but have increased “dramatically”, according to the report, with thousands of tonnes now caught each year and mostly exported.

Anchovies have followed the same path northwards. “You now have an anchovy fishery, which is clearly linked to climate change – that is what the science is showing,” said Frost. The anchovies come from the Bay of Biscay, where there is a large Spanish and French fishery.

Bluefin tuna were common around the UK before the second world war, with the giant fish a popular target for “big game” fishermen. The decimation in later decades of the mackerel and herring that tuna eat then saw the giant fish disappear. But shifting mackerel and herring populations and warming waters have seen the tuna return.

Global Temperature Extremes

The week’s hottest temperature was 123.0 degrees Fahrenheit (50.5 degrees Celsius) in Death Valley, California.

The week’s coldest temperature was minus 91.0 degrees Fahrenheit (minus 68.3 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.


Roundup of Global Volcanic Activity – Ongoing Activity for the week of 19 July – 25 July 2017

Bagana | Bougainville (Papua New Guinea) : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 23 July an ash plume from Bagana drifted W at an altitude of 2.1 km (7,000 ft) a.s.l.

Bezymianny | Central Kamchatka (Russia) : KVERT reported that during 14-21 July a thermal anomaly was identified daily over Bezymianny in satellite images. A lava flow continued to move down the W flank of the dome. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Bogoslof | Fox Islands (USA) : AVO reported that during 19-25 July no significant activity at Bogoslof was observed in cloudy or mostly cloudy satellite images, and no activity was detected in seismic, infrasound, or lightning data. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Cleveland | Chuginadak Island (USA) : AVO reported that during 19-23 July elevated surface temperatures from Cleveland were identified in satellite images; no activity was observed in seismic, infrasound, or web-camera data although these data had been intermittent. On 21 July AVO noted that a new small lava dome, about 30 m in diameter and 10 m high, had appeared at the bottom of the summit crater within the previous week. The webcam recorded a weak steam plume rising from the summit crater on 25 July. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 21-25 July ash plumes from Dukono rose to altitudes of 1.5-1.8 km (5,000-6,000 ft) a.s.l. and drifted E and NE.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that explosions at Karymsky on 18 July generated ash plumes that rose 1.7 km (5,600 ft) a.s.l. Satellite images showed a weak thermal anomaly over the volcano during 18-20 July, and ash plumes drifting 117 km E on 20 July. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Kilauea | Hawaiian Islands (USA) : During 19-25 July HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea’s Overlook crater. Webcams recorded incandescence from long-active sources within Pu’u ‘O’o 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. Several large cracks running parallel to the coastline spanned the width of the delta. Surface lava flows were active above the pali and on the coastal plain about 2 km upslope from the gravel emergency route.

Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that during 19-20 July a weak thermal anomaly over Klyuchevskoy was identified in satellite images, and ash plumes drifted 300 km SW, SE, E, and NE. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Nishinoshima | Japan : The Japan Coast Guard reported that visual observations of Nishinoshima from an aircraft during the afternoon of 11 July confirmed that the eruption was ongoing. Emissions from the center of the cone were grayish white and tephra was ejected. The lava flow on the W flank continued to enter the ocean. Based on a pilot observation the Tokyo VAAC reported that on 18 July an ash plume rose to 3 km (10,000 ft) a.s.l.

Poas | Costa Rica : OVSICORI-UNA reported that during 19-24 July plumes of magmatic gases, water vapor, and aerosols were emitted from Poás’s vent A (Boca Roja), and plumes of gases, water vapor, and abundant yellow particles of native sulfur rose from vent B (Boca Azufrada). Plumes rose 300-500 m above the vents and drifted W and SW.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that since the beginning of July there had been a gradual increase in activity at Sabancaya associated with rising magma and increased sulfur dioxide gas emissions. Gas-and-ash plumes rose to moderate heights, between 2.5 and 4.5 km above the crater rim. On 22 July winds shifted S and SE, causing ashfall in Lluta (30 km SW), Huanca (75 km SSE), and in some parts of Arequipa (80 km SSE).

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly was identified daily during 14-21 July in satellite images over Sheveluch. Based on video and satellite data explosive activity lasting about 8 hours on 24 July generated ash plumes that rose 11.5-12 km (37,700-39,400 ft) a.s.l. and drifted almost 700 km NE. Strong pyroclastic flows were also observed. The Aviation colour Code was raised to Red (the highest level on a four-colour scale). Later that day only steam-and-gas emissions with a small amount of ash were noted; the Aviation colour Code was reduced to Orange.

Sinabung | Indonesia : Based on PVMBG and pilot observations, satellite and webcam images, and wind data, the Darwin VAAC reported that during 19-25 July ash plumes from Sinabung rose 2.7-6.1 km (9,000-20,000 ft) a.s.l. and drifted in multiple directions.

Suwanosejima | Ryukyu Islands (Japan) : Based on JMA notices and satellite-image analyses, the Tokyo VAAC reported that during 18-19 July ash plumes from Suwanosejima rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted E.

Turrialba | Costa Rica : OVSICORI-UNA reported that during 19-24 July plumes of water vapor, aerosols, and magmatic gases rose as high as 500 m above Turrialba’s crater rim, and on most nights incandescence emanated from Cráter Oeste. The emissions contained ash during 20-22 July. Minor ashfall was reported in Coronado (San José) on 20 July, and in Sabanilla de Montes de Oca (30 km WSW) on 22 July.
