Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

There are no current tropical storms, Tropical Cyclone Fani has now dissipated over India.


India – Two people died Friday after Cyclone Fani slammed into eastern India, officials said, as the storm sent coconut trees flying, blew away food stands and cut off power and water. The monster weather system, which made landfall at the eastern holy city of Puri in the morning, is one of the strongest to come in off the Indian Ocean in years, with winds gusting at speeds of up to 200 kilometres per hour. In recent days, authorities in Odisha state, where 10,000 people died in a 1999 cyclone, have evacuated more than a million people as they fret about a possible 1.5-metre (five-foot) storm surge sweeping far inland.

USA – Eight storm-related deaths were reported across the United States this week as a slow-moving storm pounded an area from southern Texas to the Ohio River Valley, leaving more than 20 million people under a flash flood watch or advisory. Seven of those deaths were caused by flooding, while one person was killed by a tornado in southern Oklahoma. Record-breaking flooding from the Mississippi River has devastated the Midwest. On Thursday, waters rose above the record set during the Great Flood of 1993, and officials say it could be a month before the water completely clears.


Cholera – Mozambique

Officials declared a cholera outbreak in northern Mozambique on Thursday, a week after cyclone winds, floods and heavy rains hit the area.

Cyclone Kenneth crashed into the province of Cabo Delgado on Thursday last week, flattening entire villages with winds of up to 280 kph and killing at least 41 people.

Fourteen cases of cholera have been detected, 11 of which are in the port town of Pemba and three in the district of Mecufi.

Ebola – DR Congo

Kinshasa – More than 1 000 people have died from Ebola in the latest outbreak in Congo, the country’s health ministry said Friday. A ministry statement sent to dpa said 1,008 people have now died from the virus, while 1,529 cases have been recorded. The grim milestone comes as health care workers battle to contain the deadly disease amid attacks on their clinics and staff.

Plague – Mongolia

Health authorities in Mongolia are reporting two deaths in Ulgii district in westernmost Mongolia. Preliminary test results show that bubonic plague is the likely caused the deaths of the husband and wife, according to the Siberian Times. It is reported that the couple contracted the deadly infection after consuming infected marmot.


Global Volcanic Activity – Ongoing Activity for the week of 24 April – 30 April 2019

Agung | Bali (Indonesia) : PVMBG reported that at 0534 on 30 April a dense gray ash plume from Agung rose 1 km above the crater rim and drifted E. The Alert Level remained at 3 (on a scale of 1-4) with the exclusion zone set at a 4-km radius.

Dukono | Halmahera (Indonesia) : Based on satellite and wind model data, and information from PVMBG, the Darwin VAAC reported that during 24-27 and 29-30 April ash plumes from Dukono rose to altitudes of 1.5-2.1 km (5,000-7,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and visitors were warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 21-22 and 24 April that sent ash plumes up to 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).

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that a weak thermal anomaly over Karymsky was visible in satellite images during 18-21 April. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Krakatau | Indonesia : PVMBG reported that there were 19 events during 22-28 April recorded by Anak Krakatau’s seismic network; no emissions from the events were visually observed, even though the visibility was a mix of clear and foggy conditions. The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to remain outside of the 2-km radius hazard zone from the crater.

Merapi | Central Java (Indonesia) | 7.54°S, 110.446°E | Elevation 2910 m

PVMBG reported that during 22-28 April the lava dome at Merapi continued to grow slowly, with any extruded material channeled into the SE-flank Gendol River drainage. White emissions rose 70 m. Five block-and-ash flows traveled as far as 1.2 km in the Gendol drainage on 24 April. The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to remain outside of the 3-km exclusion zone.

Nevados de Chillan | Chile : SERNAGEOMIN reported that the lava dome in Nevados de Chillán’s Nicanor Crater continued a cycle of slow growth and partial destruction from explosions during 23-30 April. The pulsating, generally white, emissions were sometimes gray and rose no higher than 900 m above the crater rim and drifted NW, S, and SE. Nighttime webcam data showed incandescent ejecta around the crater. The Alert Level remained at Orange, the second highest level on a four-colour scale, and residents were reminded not to approach the crater within 3 km. ONEMI maintained an Alert Level Yellow (the middle level on a three-colour scale) for the communities of Pinto, Coihueco, and San Fabián.

Poas | Costa Rica : OVSICORI-UNA reported that on 24 April a very diffuse ash emission rose from Poás. Incandescence from vent A (Boca Roja) was sometimes visible during 24 and 27-28 April.

Reventador | Ecuador : IG reported that during 23-30 April periodic seismic data from Reventador’s network indicated a high level of seismic activity, including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions. Steam, gas, and ash plumes sometimes rose higher than 1 km above the crater rim and drifted N, NW, W, and SW. Incandescent blocks were observed rolling 500-800 m down the flanks. Inclement weather sometimes prevented visual observations.

Ruapehu | North Island (New Zealand) : GeoNet reported that the period of high water temperatures at Ruapehu’s summit Crater Lake along with elevated tremor levels was over. Tremor levels began to decline on 16 April and by 29 April was described as weak. The lake water reached a peak temperature of 44 degrees Celsius on 19 April and then began cooling; the temperature was 39 degrees Celsius by 29 April. The report noted that the probability of an eruption during a heating cycle had decreased with the decreasing activity. The Volcanic Alert Level remained at 1 (minor volcanic unrest) and the Aviation colour Code remained at Green.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch’s lava dome was identified daily in satellite images during 18-26 April. Ash plumes were visible drifting 300 km NE during 22-23 April. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Turrialba | Costa Rica : OVSICORI-UNA reported that a diffuse ash emission rose from Turrialba on 24 April, and an emission with low ash content drifted N on 26 April. At 0722 on 27 April a small, short-duration eruption generated an ash plume that rose less than 100 m above the crater rim.

Veniaminof | United States : On 30 April AVO lowered the Aviation colour Code for Veniaminof to Green and the Volcano Alert Level to Normal, noting that signs of unrest had continued to decline over the previous four months since the eruption ended in early January. Low-level tremor, slightly elevated surface temperatures, and minor steam emissions continued and considered typical activity for a post-eruptive period.
