In spite of uncertainty emanating from Greece crisis, eurozone growth this year revised higher

Economic growth across the 19-country eurozone this year has been revised up to multi-year highs, in a further indication that the region managed to withstand the escalating crisis in Greece.

Official figures from the European Union's statistics agency show that the eurozone economy grew by 0.4 percent in the second quarter from the previous three-month period, against the previous estimate of 0.3 percent.

Eurostat also revised up growth for the first quarter to 0.5 percent from the previous estimate of 0.4 percent. That's now the highest quarterly growth rate since the third quarter of 2010.

Following the revisions, the statistics agency said the eurozone economy was 1.5 percent bigger in the second quarter than it had been the year before. That represents a four-year high.
