The 2013 Bohol earthquake occurred on October 15 at {{tooltip|8:12:31 PST|0:12:31 UTC}} in Bohol, an island province located in Central Visayas, Philippines.{{cite news|url=http://newsinfo.inquirer.net/507617/quake-death-toll-now-over-60|title=Death toll from Bohol quake jumps to 85|newspaper=Philippine Daily Inquirer|date=October 15, 2013|access-date=October 15, 2013|first=Frances|last=Mangosing}} The magnitude of the earthquake was recorded at {{M|w|link=y}} 7.2, its epicenter in the vicinity of {{convert|6|km}} {{nowrap|S 24° W}} of Sagbayan, and its depth of focus at {{convert|12|km}}.{{cite web|url=http://hosted.ap.org/dynamic/stories/A/AS_PHILIPPINES_EARTHQUAKE?SITE=AP&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2013-10-15-04-21-10|title=Death toll in Philippines quake jumps to 93|agency=Associated Press|date=October 15, 2013|access-date=October 15, 2013|first=Bulilit|last=Marquez}} It affected the whole Central Visayas region, particularly Bohol and Cebu. The earthquake was felt in the whole Visayas area and as far as Masbate island in the north and Cotabato provinces in southern Mindanao.
According to official reports by the National Disaster Risk Reduction and Management Council (NDRRMC), 222 were reported dead, 8 were missing, and 976 people were injured. In all, more than 73,000 structures were damaged, of which more than 14,500 were destroyed.
It was the deadliest earthquake in the Philippines in 23 years since the 1990 Luzon earthquake. The energy released by the quake was equivalent to 32 of the bombs dropped in Hiroshima.{{cite news|url=http://newsinfo.inquirer.net/507373/bohol-earthquake-strongest-to-hit-visayas-and-mindanao-in-over-20-years|title=Bohol earthquake strongest to hit Visayas and Mindanao in over 20 years|newspaper=Philippine Daily Inquirer|date=October 15, 2013|access-date=October 15, 2013|first=Jeannette I.|last=Andrade}} Previously, Bohol was also hit by an earthquake on February 8, 1990 that damaged several buildings and caused a tsunami.{{cite news|url=https://www.nytimes.com/2013/10/16/world/asia/major-earthquake-strikes-central-philippines.html|title=Major Earthquake Strikes Central Philippines|newspaper=The New York Times|date=October 15, 2013|access-date=October 15, 2013|first=Floyd|last=Whaley}}{{cite news|url=http://www.gmanetwork.com/news/story/330954/scitech/science/bohol-quake-as-strong-as-32-atomic-bombs-phivolcs|title=Bohol quake as strong as 32 atomic bombs –Phivolcs|work=GMA News|date=October 15, 2013|access-date=October 15, 2013|author=Marc Jayson Cayabyab}}
On November 7, just three weeks after the earthquake, Super Typhoon Haiyan (Yolanda) struck the region. Although the storm's eye missed the area affected by the earthquake, it sent some 40,000 Boholanos still living in temporary shelters back to evacuation centers and disrupted relief efforts in the province.{{cite news|title=For Boholanos: After super quake, a super typhoon|url=http://newsinfo.inquirer.net/524245/for-boholanos-after-super-quake-a-super-typhoon|newspaper=Philippine Daily Inquirer|access-date=November 13, 2013|author=Carmel Lois Matus|date=November 10, 2013}}
Geology
The earthquake produced an approximate {{convert|50|km}}-long, {{convert|12|km}}-wide northeast trending zone of uplift with an approximate {{convert|8|km}} long discontinuous ground rupture indicating predominantly reverse-slip movement on a southeast dipping fault.{{Cite journal|last1=Rimando|first1=Jeremy M.|last2=Aurelio|first2=Mario A.|last3=Dianala|first3=John Dale B.|last4=Taguibao|first4=Kristine Joy L.|last5=Agustin|first5=Krissen Marie C.|last6=Berador|first6=Al Emil G.|last7=Vasquez|first7=Adriann A.|date=2019|title=Coseismic Ground Rupture of the 15 October 2013 Magnitude (MW) 7.2 Bohol Earthquake, Bohol Island, Central Philippines|journal=Tectonics|volume=38|issue=8|pages=2558–2580|doi=10.1029/2019TC005503|bibcode=2019Tecto..38.2558R|issn=1944-9194|doi-access=free}}
Initially it was thought that the epicenter was {{convert|2|km}} east of Carmen, Bohol, triggered by the East Bohol Fault. However, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the 7.2 earthquake may have been caused by a previously undiscovered fault transecting Bohol running east-northeast-west-southwest parallel to the island's northwest coast.{{cite news|url=http://www.gmanetwork.com/news/story/331158/scitech/science/phivolcs-new-fault-line-may-have-been-source-of-bohol-earthquake|title=Phivolcs: New fault line may have been source of Bohol earthquake|date=October 16, 2013|access-date=October 17, 2013|work=GMA News}}{{cite web|url=https://news.yahoo.com/caused-deadly-philippines-earthquake-165838659.html|title=What Caused the Deadly Philippines Earthquake?|publisher=Yahoo News Philippines|work=LiveScience|date=October 16, 2013|access-date=October 16, 2013|first=Becky|last=Oskin}} This was apparent in the pattern of epicenters of the subsequent aftershocks.
Documentation of the nearly continuous northern terminus of the earthquake ground rupture revealed its association to preexisting scarps of the previously unmapped, Quaternary-active North Bohol Fault (NBH). Trenching across the rupture at four sites not only reveals the geometry and kinematics of the fault but also shows at least one or two pre-2013 surface rupturing events. Onshore geologic mapping and offshore seismic reflection profiles demonstrate the presence of an island-wide, northeast–southwest trending fold-and-thrust belt through which deformation related to the regional shortening across the Visayan Sea Basin in the central Philippines is likely distributed.
Displacement along the northeastern segment of the NBF in Inabanga is significantly larger in the northeast than in the southwest. In the northeast, the displacement is mostly {{convert|2|m}} and reaches a maximum of {{convert|5|m}}, while in the southwest, the displacement is mostly less than {{convert|1|m}}. The maximum and average displacements, which were measured along the nearly continuous approximately {{convert|2|km}} long ground rupture in Sitio Cumayot, Barangay Anonang, Inabanga, are around {{convert|5|and|2|m}}, respectively.

{{Main|Bohol fault system}}
PHIVOLCS reported that the NBF, which generated the earthquake, is a northeast–southwest trending reverse fault along the western sector of Bohol island. Surface ruptures ranging from {{convert|0.10|m}} to as high as {{convert|5|m}} in vertical displacements were exposed in barangay Anonang in Inabanga, Bohol. The mapped surface of the NBF is {{convert|6|km}} long from barangay New Anonang in Buenavista to barangay Napo in Inabanga and generally trends 40 degrees northeast and dips at 50 degrees southeast.{{cite web|url=http://www.phivolcs.dost.gov.ph/index.php?option=com_content&view=article&id=3145:geologic-impacts-of-the-15-october-2013-mw72-north-bohol-fault-earthquake-bohol-island-philippines&catid=60:latest-news&Itemid=500001|title=Geologic Impacts of the 15 October 2013 Mw7.2 North Bohol Fault Earthquake, Bohol Island, Philippines|publisher=Philippine Institute of Volcanology and Seismology|date=October 28, 2013|access-date=October 28, 2013}}
The longest, continuous individual trace mapped by the team is approximately {{convert|2|km}} in Anonang. In this barangay, surface rupture trends 40 degrees northeast. The surface rupture manifested as prominent fault scarps, which range from {{convert|2|m}} to {{convert|5|m}} of vertical displacements. Other geomorphic manifestations observed in Anonang include {{convert|2.5|m}} vertical displacement of Cawasan Creek in Sitio Calubian, producing a small waterfall at the point where the fault transects the creek. Other typical features associated with reverse faulting, such as scallops, bulges and warps, were also observed in the deformation zone, which extended as wide as {{convert|30|m}} in some places.

Aftershocks continued to rattle Bohol Island and Cebu for several months. By December 6, 2013, 4,026 aftershocks were recorded, 114 of which were felt.{{cite news|last=Flores|first=Helen|date=December 6, 2013|title=Strong quake moved part of Bohol to Cebu – Phivolcs|work=ABS-CBN News|publisher=ABS-CBN Interactive|url=http://www.abs-cbnnews.com/nation/regions/12/06/13/strong-quake-moved-part-bohol-cebu-phivolcs|access-date=December 16, 2013}} Included in the aftershocks was the 5.3 magnitude tremor experienced at 12:59 a.m. on October 26,{{cite news|url=http://www.gmanetwork.com/news/story/332615/news/regions/ndrrmc-death-toll-from-central-visayas-quake-now-213|title=NDRRMC: Death toll from Central Visayas quake now 213|work=GMA News|date=October 26, 2013|access-date=October 26, 2013|author=LBG, and GMA News}} and another 4.8 magnitude quake at 1:28 p.m. on November 12, centered at San Isidro, Bohol.{{cite web|title=M4.8 – 0 km NW of San Isidro, Philippines (BETA)|url=https://earthquake.usgs.gov/earthquakes/eventpage/usb000kw1a#summary|publisher=United States Geological Survey|access-date=November 13, 2013}}

Casualties and infrastructure damage
The earthquake struck as the Philippines was observing the Muslim holiday of Eid-al-Adha. The public holiday had closed schools, some businesses, and offices which helped reduce the number of casualties.
A total of ₱2.25 billion worth of damage to public buildings, roads, bridges, and flood controls was reported in Bohol and Cebu. A total of 671,103 families or more than 3.2 million people were affected by the quake. Out of the total number of affected, 71,822 families or more than 348,000 people were displaced.
=Bohol=
The most casualties and damage occurred in Bohol. A total of 209 people were confirmed dead, 877 people were confirmed injured, and eight confirmed missing. A rough estimate of the damage was expected to be at least at ₱2.2 billion. The town of Loon had the largest number fatalities (67). A total of 1,255,128 people (the province's entire population) were affected by the quake. Nearly 71,900 residential houses were damaged (out of which 14,480 were destroyed), with the towns of Loon, Tubigon, Carmen, and Calape among the worst affected.
A building at the Tagbilaran Port Terminal and a ceiling of the second floor and the tower of Tagbilaran Airport collapsed. Loboc Church, Loon Church and Maribojoc Church collapsed; the façade of Baclayon Church and its bell tower were totally damaged. Other churches, including those in Loay, Dauis, Dimiao, and Tubigon were also severely damaged.{{cite news|url=http://www.rappler.com/nation/41381-ten-churches-damaged-cebu-bohol-quake|title=Heartbreaking: 10 iconic churches in Bohol, Cebu damaged|work=Rappler|date=October 15, 2013|access-date=October 15, 2013|first=Pia|last=Ranada}} In Carmen, a freestanding bell tower and an observation deck in the island's renowned Chocolate Hills were destroyed, with some hills themselves damaged by landslides.{{cite news|url=https://www.reuters.com/article/us-philippines-quake-idUSBRE99E01R20131015|title=Strong quake kills at least 74 in central Philippines|agency=Reuters|date=October 15, 2013|access-date=October 16, 2013|author=Erik De Castro}}{{cite news|url=http://www.gmanetwork.com/news/photo/46590/chocolate-hills-viewing-deck-destroyed-by-earthquake|title=Chocolate Hills viewing deck destroyed by earthquake|work=GMA News|date=October 15, 2013|access-date=October 16, 2013}}{{cite news|url=http://www.abs-cbnnews.com/nation/regions/10/15/13/prized-chocolate-hills-damaged-quake|title=Prized Chocolate Hills damaged by quake|work=ABS-CBN News|date=October 15, 2013|access-date=October 16, 2013}}

Effects
=Transportation=
Several flights from Cebu and Bohol airports and airport operations were put on hold as a response to check the safety status of the airport buildings. Mactan International Airport was later opened before midday;{{cite web|url=https://www.bloomberg.com/news/2013-10-15/strongest-philippine-quake-in-a-year-kills-4-damages-buildings.html|title=Aquino to Visit Philippine Earthquake Zone as Deaths Rise to 67|publisher=Bloomberg News|date=October 16, 2013|access-date=October 16, 2013|author=Clarissa Batino & Joel Guinto}} flights between Manila and Bohol were delayed due to temporary suspension of operations in Tagbilaran Airport for about three hours.{{cite news|url=http://www.sunstar.com.ph/cebu/local-news/2013/10/16/malls-closed-sailing-ban-imposed-cebu-308872|title=Malls closed, sailing ban imposed in Cebu|work=SunStar|date=October 16, 2013|access-date=October 16, 2013|author=Elias O.

=Health=
Many Bohol residents were left without adequate safe drinking water and sanitary facilities after the quake. Consequently, serious public health issues arose such as cases of diarrhea and water-borne diseases. Worst affected were the municipalities closest to the epicenter, such as Sagbayan, San Isidro, Calape, Tubigon, Clarin and Catigbian.{{cite web|url=http://www.oxfam.org/en/pressroom/pressrelease/2013-10-21/serious-public-health-issues-earthquake-bohol-philippines|title=Serious public health issues in earthquake-hit areas of Bohol, Philippines|publisher=Oxfam International|date=October 21, 2013|access-date=October 23, 2013|location=Manila, Philippines}}
There were also threats to public health. Community health centers and hospitals were rendered useless, resulting in the use of makeshift wards outside the affected buildings. Food supply was also disrupted, with many markets unable to operate a week after the quake. Furthermore, prolonged periods of aftershocks forced the population to take residence in makeshift shelters, afraid to go inside weakened buildings, and causing psychological trauma.{{cite news|url=http://www.rappler.com/nation/41787-bohol-quake-aftermath-six-days-on|title=After Bohol quake: Worry, recovery|work=Rappler|date=October 20, 2013|access-date=October 20, 2013|first=Bea|last=Cupin|location=Tagbilaran City, Philippines}}
