Storms and Floods

Tropical Storms

In the Western Pacific –

Tropical storm Rumbia was located 231 nm eastward of Hanoi, Vietnam. Weakening – the last warning has been issued on this system.

In the Eastern Pacific –

Tropical storm Dalila was located about 180 mi (290 km) WSW of Manzanillo, Mexico. Dalila continues to strengthen while moving away from Mexico. The storm has maximum sustained winds of 60 mph (95 kph).

The tropical storm shifted and spared the Philippine capital Sunday but stranded thousands of commuters, toppled trees and knocked out power in outlying provinces. Forecasters had predicted that Tropical Storm Rumbia would hit the densely populated Manila metropolis early Sunday, sparking emergency preparations. Instead it veered away and struck Batangas province, about 80 kilometres (50 miles) south of Manila, then blew away toward the South China Sea.

There were no immediate reports of deaths or injuries from the storm, which packed sustained winds of 65 kilometres (40 miles) per hour and gusts of 80 kph (50 mph). Strong winds and rain pounded on roofs and swayed trees before dawn in the capital of more than 12 million people, then the sun emerged. The government’s disaster-response agency said 1,600 villagers fled their homes in Albay province, southeast of Manila, amid heavy rains, while more than 10,000 commuters were stranded as ferry and cargo boats suspended trips. Several provinces reported power outages and minor landslides. Rumbia is the seventh storm or typhoon to hit the Philippines this year. An average of 21 strike the country in a year.

Heavy rainfall has uprooted trees and caused a landslide in Sydney, Australia. The landslide hit platform 4 at Harris Park Station near Parramatta. No injuries were reported.


Arizona Wildfire – USA – Update

The wildfire continues to burn out of control. About 200 additional firefighters have been brought to tackle the blaze, bringing the total force to about 400.

The 0% contained wildfire has scorched some 8,400 acres (3,400 hectares) of land. Scores of homes have been destroyed and two towns evacuated.

In recent days, dozens of people across western US states have been treated for exhaustion and dehydration, amid a heat wave. Temperatures in some areas were expected to reach 54C (130F), close to the world’s all-time high recorded 100 years ago in California’s Death Valley.


Roundup of Global Volcanic Activity:

Hekla (Iceland): The trend of rapid inflation that started in April has not continued, but was partly reverted and significant deformation has stopped for now. Nothing suggests for now that an eruption is imminent, but Hekla is known for providing close to no (seismic) warning before eruptions.

Kizimen (Kamchatka): KVERT reports no changes in activity: moderate seismic activity of the volcano suggests that the growth of an extrusion at the volcano summit continues. Incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks, and strong and moderate gas-steam activity accompany this process. (KVERT)

Shiveluch (Kamchatka): Accompanied by moderate tremor levels, the lava dome continues to grow and produce hot avalanches on the western flank. Strong degassing accompanies this process. (KVERT)

Tolbachik (Kamchatka): KVERT reports no change in activity. Tremor remains at similar levels as during the past month. A large thermal anomaly continues to show the active lava flow field to the S and SE from the southern fissure.

Taal (Luzon, Philippines): Seismic activity remains above background. During 26-27 June, PHILVOLCS recorded 15 volcanic earthquakes. Other parameters (water temperature and level, pH, deformation) have shown no significant variation during the latest surveys in June. The edifice overall remains slightly inflated when compared to 2011, and CO2 emissions, when last measured in March, were slightly higher then than during the end of November.

Mayon (Luzon Island): PHILVOLCS maintains alert level 1 for the volcano. No significant seismic activity is taking place, and no crater glow has been observed recently. Degassing is at normal levels, but ground deformation measurements show that the edifice is still slightly inflated compared to January 2010 baselines. Alert level 1 means that it is thought that presently no magmatic eruption is imminent, but it is strongly advised to stay out of a radius of 6 km around the volcano because of the danger of sudden (phreatic) explosions as well as rockfalls and landslides and mud flows during heavy rainfall.

Veniaminof (Alaska Peninsula, USA): Nearly continuous, low-level volcanic tremor has been present during the past 24 hours, but decreased significantly today. Satellite observations continue to show elevated surface temperatures at the intracaldera cone of Veniaminof Volcano, although images from this morning have been cloudy and the volcano can not be observed directly. The seismic data indicate an ongoing low-level eruption characterized by effusion of lava and emission of minor amounts of ash and steam. (AVO)

Pavlov (Alaska Peninsula, USA): The volcano has been quiet during the past 24 hours, but it is unclear whether this is already an end or only a pause in the eruption, or whether some weak activity is still continuing. AVO reports relatively continuous, but low-level tremor being still present and it is possible that minor emissions of ash, gas and steam and low-level lava fountaining are still occurring intermittently.

Popocatépetl (Central Mexico): Surface activity has been low with about 1-2 weak emissions of steam and gas per hour. A number of small earthquakes have been occurring during the last 24 hours at the volcano. Degassing remains strong and incandescence is visible at the summit at night.

Santa María / Santiaguito (Guatemala): Activity remains low. A weak explosion was captured by the INSIVUMEH webcam this morning at 05:14, producing a small plume rising 300 m.

Pacaya (Guatemala): INSIVUMEH reports no explosions heard or seen, but the seismic signal suggests that small explosive activity continues.

Fuego (Guatemala): The volcano has calmed down during the past day. Only 5 relatively weak explosions were recorded. Seismic activity has decreased as well.

Reventador (Ecuador): IGPEN characterizes the activity as moderate with seismic activity mainly related to internal fluid movements as well weak pulses of tremor and explosion signals. The volcano is hidden in clouds most of the time, but a thermal anomaly has become visible at the summit again on recent MODIS satellite data, possibly related to a recent small effusion of lava there.
