Article: With the building of Christian basilicas in the late 4th century, wall and ceiling mosaics were adopted for Christian uses. The earliest examples of Christian basilicas have not survived, but the mosaics of Santa Constanza and Santa Pudenziana, both from the 4th century, still exist. The winemaking putti in the ambulatory of Santa Constanza still follow the classical tradition in that they represent the feast of Bacchus, which symbolizes transformation or change, and are thus appropriate for a mausoleum, the original function of this building. In another great Constantinian basilica, the Church of the Nativity in Bethlehem the original mosaic floor with typical Roman geometric motifs is partially preserved. The so-called Tomb of the Julii, near the crypt beneath St Peter's Basilica, is a 4th-century vaulted tomb with wall and ceiling mosaics that are given Christian interpretations. The Rotunda of Galerius in Thessaloniki, converted into a Christian church during the course of the 4th century, was embellished with very high artistic quality mosaics. Only fragments survive of the original decoration, especially a band depicting saints with hands raised in prayer, in front of complex architectural fantasies.

Question: What Christian church besides the Santa Costanza was built in the 4th century?
Ans: Santa Pudenziana

Article: The map of earthquake intensity published by CEA after surveying 500,000 km2 of the affected area shows a maximum liedu of XI on the China Seismic Intensity Scale (CSIS), described as "very destructive" on the European Macroseismic Scale (EMS) from which CSIS drew reference. (USGS, using the Modified Mercalli intensity scale (CC), also placed maximum intensity at XI, "very disastrous".) Two south-west-north-east stripes of liedu XI are centered around Yingxiu, Wenchuan (the town closest to the epicenter of the main quake) and Beichuan (the town repeatedly struck by strong aftershocks including one registering MS 6.1 on Aug 1, 2008), both in Sichuan Province, occupying a total of 2,419 km2. The Yingxiu liedu-XI zone is about 66 km long and 20 km wide along Wenchuan–Dujiangyan–Pengzhou; the Beichuan liedu-XI zone is about 82 km long and 15 km wide along An County–Beichuan–Pingwu. The area with liedu X (comparable to X on EMS, "destructive" and X on MM, "disastrous") spans 3,144 km2. The area affected by earthquakes exceeding liedu VI totals 440,442 km2, occupying an oval 936 km long and 596 km wide, spanning three provinces and one autonomous region.

Question: How did the USGS rate the earthquake?
Ans:
very disastrous
