From Reuters:

JAKARTA (Reuters) - A powerful undersea earthquake has hit
Indonesia's West Java island, a telephone text message from the
country's Meteorological agency said on Thursday.

The agency did not give a tsunami warning and there were no
immediate reports of damage or casualties, but the quake caused panic
in parts of the densely inhabited Java island.

The Indonesian agency said the quake had a 7.0 magnitude, while the
U.S. geological survey said on its Web site the magnitude was 7.4.

The quake struck 75 km (46.60 miles) northwest of Indramayu and was at a depth of 286 km, the Indonesian agency said.

The quake could be felt by residents in the capital Jakarta, as well
as in the nearby city of Bandung and in the town Yogyakarta in central
Java.

Indonesia suffers from frequent earthquakes. It lies on an active seismic belt in the so-called "Pacific Ring of Fire".
