It has rocks up to 1 m high which are all below at high tide. It has guano deposits. PRC built a navy harbor by blasting, piling up and cementing coral. The establishment is 8,080 square meters and 14 miles (23 km) long. A marine observation station was built in 1988. Coconut, fir, and banyan trees were planted. Actually composed of 3 reefs.[1]
A few rocks are permanently above sea level and it encloses a lagoon.[1] Filipino soldiers from nearby Second Thomas Reef, as well as Filipino fisherfolks, visit this reef daily to fish. Much of the reef is above water at low tide.
The fourteenth largest Spratly island. About 6 miles (10 km) southwest of Philippine-occupied Lawak Island (Nanshan Island). It has no underground water source. It is a low, flat, sandy cay, 240 by 90 m, subject to erosion. It has a nearby reef which is above water at high tide. It has large guano deposits and no vegetation.[1] Presently, this island serves only as a military observation post for the Municipality of Kalayaan.
A sand dune, 2 m high. It has a fringing reef plus a reef 2 miles (3 km) to the south, both covered at high tide. A tw0-story building was built here. Southern reef was occupied by PRC on July 4, 1992.[1]
First Thomas Shoal: Several sources says that this feature is occupied PRC. However, other sources don't support it. PRC may have occupied this feature in the past for a brief period.
McKennan Reef: Several sources says that this feature is occupied PRC. However, other sources don't support it. Occupation is probably confused because it lies very close to PRC-occupied Hughes Reef. If not occupied by PRC, this feature is still virtually occupied by PRC.
Irving Reef: A source says it was occupied by the Philippines. However, other sources don’t support it. Because it lies in the middle of between all Philippine-occupied Spratly islands, Philippines may have effective control of this feature. Philippine naval vessels are always anchored in the region between all Philippine-occupied islands.
Scarborough Shoal: Many sources still say that this feature is not occupied. However, some sources, especially Philippine news articles, say that Philippine Navy has a permanent active presence it this feature resulting to numerous arrests of Chinese fishermen who use illegal fishing methods.
Loaita Cay, Loaita Nan, Sandy Cay and Tieshi Reef: Virtually occupied by the Philippines.
Others: All features located to the east of 116°E meridian are largely controlled by the Philippines. All features here are at most 100 miles (161 km) from Palawan's west coast. Philippine officials often dub this area as an "obvious" part of the Philippines for their close proximity with Palawan. Instead of occupying the features here, the Philippines have just built naval bases and air fields in Palawan. Many Filipino fishermen swarm this region and they closely cooperate with the Philippine Navy and Philippine Coast Guard, further boosting Philippines' control of this region. The Philippines had blasted numerous buoys and markers placed by PRC here. The Malampaya Gas Field and Reed Bank concessions are also located here.
Zero-occupancy: These are the unoccupied features. Some sources say that some of these features are occupied by Vietnam or China but most sources, including the latest, say that they are not occupied. Occupation are probably confused because the said reefs are very close to occupied features. There are many unoccupied features in the Spratly chain. The current Code of Conduct prohibits any country from acquiring new features. Many of these features are actually in between and near two or more occupied features of different countries. Thus, they serve like buffer zones. Example of this is Jones Reef which lies almost exactly between PRC-occupied Hughes Reef and Vietnamese-occupied Higgens Reef.
