The 1885 Kashmir earthquake, also known as the Baramulla earthquake occurred on 30 May in Srinagar. It had an estimated moment magnitude of Mw  6.3–6.8 and maximum Medvedev–Sponheuer–Karnik scale intensity of VIII (Damaging). At least 3,081 people died and severe damage resulted.

Tectonic setting

strike-slip movement at 5 ± 2 mm/yr.[1]

The high convergence rate means many of the plate boundary faults are accommodating strain while locked, frequently releasing them in moderate-sized earthquakes, and sometimes in very large events. The occurrence of large earthquakes makes the Kashmir region vulnerable to deadly earthquakes. The region has hosted many large and destructive earthquakes since the beginning of records in 2082–2041 BCE. The most destructive is thought have occurred in 1555, and was the last major event in the Kashmir Valley.[2]

Earthquake

The earthquake was associated with a rupture on a shallow thrust fault, part of the Himalaya convergent boundary.[2] It is located east of the rupture areas of the 2005 earthquake, and west of the 1555 earthquake. The 2005 and 1555 earthquakes are the most catastrophic events in the region with magnitudes estimated at 7.6 Mw .[3]

Southeast of the Kashmir Valley are two very large thrust faults; the Main Boundary Thrust and Panjal Thrust. To the northeast of the valley, lies the Main Mantle Thrust. The closest faults to the valley are two out-of-sequence reverse faults known as the Kolbug and Balapur faults. The 40 km (25 mi) long Balapur Fault dips northeast at a steep angle of 60°. The parallel Kolbug Fault produced a Mw  5.5 earthquake in 1963.[4]

The mainshock generated a surface rupture measuring 54 km (34 mi), with a maximum ground offset of 0.6 km (0.37 mi). The seismogenic structure responsible is named the Baramula-Loridor Fault.[2]

Damage and casualties

At 02:24 local time on Sunday, May 30, the Kashmir Valley was rocked by a strong earthquake with varying Modified Mercalli intensities of VI (Strong) to VIII (Severe). An assessment of the maximum seismic intensity on the Environmental Seismic Intensity scale indicate a degree of X. A minor foreshock occurred the night before and was felt by several residents. The mainshock was followed by damaging aftershocks that continued till August 1885. On June 15, a strong aftershock was felt.[3]

A total of 3,081 people were killed. In

natural springs.[3]

The towns of Baramulla and Sopore were destroyed. An estimated 67.33% of Baramulla's population was killed. Some 300 to 500 well-constructed wood and brick homes collapsed. Great devastation occurred in Barmulla where many people and cattle were fatally crushed. Vegetation on the nearby hillsides was wiped out by landslides. Many homes were buried. Large scarps formed on the slopes. One such landslide buried Laridura; only seven of the 47 residents survived.[3]
