Located within the Bransfield Strait, the island is roughly circular and horseshoe-shaped, with a maximum diameter around {{convert|15|km|mi|abbr=on}}. The highest peak, Mount Pond on the east side of the island, has an elevation of {{convert|539|m|ft|0|abbr=on}}, while Mount Kirkwood on the west has an elevation of {{convert|452|m|ft|abbr=on}}. Over half (57%) of the island is covered by glaciers up to 10 m thick, ice-cored moraines, or ice-covered pyroclasts. The sea has flooded the centre of the island to form a large bay, now called Port Foster, about {{convert|10|km|mi|abbr=on}} long and {{convert|7|km|mi|abbr=on}} wide. The bay has a narrow entrance, just {{convert|500|m|ft|0|abbr=on}} wide, called Neptune's Bellows. The port is a basin with a flat floor up to {{cvt|170|m}} deep with several small submarine cones and domes. The port is rimmed by a shallow coastal shelf with sandy-gravelly beaches. The outer coast of the island is characterised by {{convert|30-70|m|ft|abbr=on}} cliffs of rock or ice.{{cite book |last1=Smellie |first1=J.L. |last2=Lopez-Martinez |first2=J. |editor1-last=Lopez-Martinez |editor1-first=J. |editor2-last=Smellie |editor2-first=J.L. |editor3-last=Thomson |editor3-first=J.W. |editor4-last=Thomson |editor4-first=M.R.A. |section=Introduction |title=Geology and geomorphology of Deception Island |series=Bas Geomap Series |date=2002 |publisher=British Antarctic Survey |location=Cambridge |issn=0951-8886 |pages=1–4}}

Raven's Rock, a navigation hazard, lies {{convert|2.5|m|ft|1|abbr=on}} below the water in the middle of the channel. Just inside Neptune's Bellows lies the cove Whalers Bay, which is bordered by a large black sand beach. Several maars line the inside rim of the caldera, with some containing crater lakes (including one named Crater Lake). Others form bays within the harbour, such as the {{convert|1|km|adj=on|mi|1|abbr=on}} wide Whalers Bay. Other features of the island include Mount Kirkwood, Fumarole Bay, Sewing-Machine Needles, Telefon Bay, and Telefon Ridge.

The linear Costa Recta spanning most of the east coast is hypothesised to be a scarp of a retreated submarine fault.{{Cite journal|url=https://www.academia.edu/4107748|title=Costa Recta beach, Deception Island, West Antarctica: A retreated scarp of a submarine fault?|journal=Antarctic Science|year=2005|volume=17|issue=3|page=418|last1=Fernández-Ibáñez|first1=Fermín|last2=Pérez-López|first2=Raul|last3=Martínez-Díaz|first3=José J.|last4=Paredes|first4=Carlos|last5=Giner-Robles|first5=Jorge L.|last6=Caselli|first6=Alberto T.|last7=Ibáñez|first7=Jesús M.|doi=10.1017/S0954102005002841|bibcode=2005AntSc..17..418F|hdl=20.500.12110/paper_09541020_v17_n3_p418_FernandezIbanez |s2cid=54090378|hdl-access=free}}

Deception Island is the exposed portion of an active shield volcano 30 km in diameter. The island is associated with Bransfield Basin seafloor spreading that includes a volcanic ridge and seamounts dating back to the Pleistocene. Deception Island volcanic ash layers have been found on other South Shetland Islands, the Bransfield Strait, the Scotia Sea and in South Pole ice cores. Volcanic tremors are common, originating from depths less than 10 km. Historical eruptions occurred in 1839–1842, 1967, 1969, and 1970.{{rp|iii}} Stratigraphy of the island is characterised by the pre-caldera Port Foster Group and the post-caldera Mount Pond Group, both within the Deception Island Volcanic Complex. The Port Foster Group's principal outcrops are located at South Point, Cathedral Crags near Entrance Point and north of Punta de la Descubierta, forming spectacular coastal cliffs along the western portion of the island. The group is composed of the Fumarole Bay Formation consisting of hydrovolcanic tephra, the Basaltic Shield Formation consisting of lavas and Strombolian scoria, and the Outer Coast Tuff Formation consisting of lapilli-tuffs. The Mount Pond Group dominates the surface geology and consists of the pyroclastic Baily Head and Pendulum Cove formations, both formed during hydrovolcanic eruptions, and the Stonethrow Ridge Formation consisting of tuff cone and maar deposits. The caldera collapsed as either a hydrovolcanic eruption of the Outer Coast Tuff Formation, releasing about 30 cubic kilometers of magma, or passively due to regional tectonics, since the island is at the intersection of the Bransfield Strait rift and the orthogonal Hero fracture zone.{{cite book |last1=Smellie |first1=J.L. |year=2002 |section=Geology |editor1-last=Lopez-Martinez |editor1-first=J. |editor2-last=Smellie |editor2-first=J.L. |editor3-last=Thomson |editor3-first=J.W. |editor4-last=Thomson |editor4-first=M.R.A. |title=Geology and Geomorphology of Deception Island |series=Bas Geomap Series |publisher=British Antarctic Survey |location=Cambridge |issn=0951-8886 |pages=11–30}}{{cite book |last1=Rey |first1=J. |last2=Maestro |first2=A. |last3=Somoza |first3=L. |last4=Smellie |first4=J.L. |year=2002 |section=Submarine morphology and seismic stratigraphy of Port Foster |editor1-last=Lopez-Martinez |editor1-first=J. |editor2-last=Smellie |editor2-first=J.L. |editor3-last=Thomson |editor3-first=J.W. |editor4-last=Thomson |editor4-first=M.R.A. |title=Geology and Geomorphology of Deception Island |series=Bas Geomap Series |publisher=British Antarctic Survey |location=Cambridge |issn=0951-8886 |page=41}}{{cite book |last1=Gonzalez-Ferran |first1=O. |year=1991 |section=The Bransfield rift and its active volcanism |editor1-last=Thomson |editor1-first=M.R.A. |editor2-last=Crame |editor2-first=J.A. |editor3-last=Thomson |editor3-first=J.W. |title=Geological Evolution of Antarctica |publisher=Cambridge University Press |place=Cambridge, UK |isbn=9780521372664 |pages=508–509}}

The first authenticated sighting of Deception Island was by the British sealers William Smith and Edward Bransfield from the brig Williams in January 1820. It was first visited and explored by the American sealer Nathaniel Palmer on the sloop Hero the following summer, on 15 November 1820. He remained for two days, exploring the central bay.{{cite journal |last=Dibbern |first=J.

Palmer was part of an American sealing fleet from Stonington, Connecticut, under the command of Benjamin Pendleton, consisting of 6 ships. Port Fisher was used as their operational base from 1820 to 1821. Palmer met Bellingshausen close to the island in Jan. 1821, during the First Russian Antarctic Expedition.

A lighthouse named Surgidero Iquique was built on the island to guide vessels into Deception Station.

Over the next few years, Deception became a focal point of the short-lived fur-sealing industry in the South Shetlands. The industry began with a handful of ships in the 1819–1820 summer season, rising to nearly a hundred in 1821–1822. While the island did not have a large seal population, it was a perfect natural harbour, mostly free from ice and winds, and a convenient rendezvous point. Some men likely lived ashore in tents or shacks for short periods during the summer, though no archaeological or documentary evidence survives to confirm this. Massive overhunting meant that the fur seals neared extinction in the South Shetlands within a few years, and the sealing industry collapsed as quickly as it had begun. Deception was abandoned again in approximately 1825.

Sealing captain Robert Fildes charted Port Foster in 1820–1821, which in 1829 became the first published Antarctica nautical chart.

In 1829, the British Naval Expedition to the South Atlantic under the command of Captain Henry Foster in {{HMS|Chanticleer|1808|6}} stopped at Deception. The expedition conducted a topographic survey and scientific experiments, particularly pendulum and magnetic observations.{{cite book |first=Gordon Elliott |last=Fogg |year=1992 |title=A History of Antarctic Science |place=Cambridge, UK |publisher=Cambridge University Press |pages=72–74}} A watercolour made by Lieutenant Kendall of the Chanticleer during the visit may be the first image made of the island. A subsequent visit by the American elephant-sealer Ohio in 1842 reported the first recorded volcanic activity, with the southern shore "in flames".

File:Dørnberger - Flensing av blåhval, Whalers Bay, Deception Island.jpg at Whalers Bay, Deception Island. By 1912–1913, the island had 12 factory ships, and 27 catchers, occupying 200 people, with 3,000 rotting whale carcasses in the Whalers Bay area.{{rp|4}}]]

The second phase of human activity at Deception began in the early 20th century. In 1904, an active whaling industry was established at South Georgia, taking advantage of new technology and an almost untouched population of whales to make rapid profits. It spread south into the South Shetland Islands, where the lack of shore-based infrastructure meant that the whales had to be towed to moored factory ships for processing; these needed a sheltered anchorage and a plentiful supply of fresh water, both of which could be found at Deception. In 1906, the Norwegian-Chilean whaling company Sociedad Ballenera de Magallanes started using Whalers Bay as a base for a single ship, the Gobernador Bories.

Other whalers followed, with several hundred men resident at Deception during the Antarctic summers and as many as 13 ships operating in peak years. In 1908, the British government formally declared the island to be part of the Falkland Islands Dependencies, thus under British control, establishing postal services and appointing a magistrate and customs officer for the island. The magistrate was to ensure that whaling companies were paying appropriate licence fees to the Falklands government and ensuring adherence to catch quotas. A cemetery was built in 1908, a radio station in 1912, a hand-operated railway also in 1912,{{cite web |last=Williams |first=Glynn |title=Railways in Antarctica |url=http://www.sinfin.net/railways/world/antarctica.html |access-date=4 September 2014}} and a small permanent magistrate's house in 1914.

The cemetery, by far the largest in Antarctica, held graves for 35 men along with a memorial to 10 more presumed drowned.{{cite conference |date = July 2007 |title=Measures adopted |conference = The Antarctic Treaty 28th Consultative Meeting 6–17 June 2005 |place=Stockholm, SE |id=Command Paper 7166 |pages = 293–299 |publisher = United Kingdom Foreign and Commonwealth Affairs Office |url = https://www.gov.uk/government/publications/the-antarctic-treaty-measures-adopted-at-the-twenty-eighth-consultative-meeting |access-date = 18 July 2013}}

These were not the only constructions; as the factory ships of the period were only able to strip the blubber from whales and could not use the carcasses, a permanent on-shore station was established by the Norwegian company Hvalfangerselskabet Hektor A/S in 1912 – up to an estimated 40% of the available oil was being wasted by the ship-based system. This was the only successful shore-based industry ever to operate in Antarctica, reaping high profits in its first years. A number of exploring expeditions visited Deception during these years, including the Wilkins-Hearst expedition of 1928, when a Lockheed Vega was flown from a beach airstrip on the first successful flights in Antarctica.

The development of pelagic whaling in the 1920s, where factory ships fitted with a slipway could tow aboard entire whales for processing, meant that whaling companies were no longer tied to sheltered anchorages. A boom in pelagic Antarctic whaling followed, with companies now free to ignore quotas and escape the costs of licences. This rapidly led to overproduction of oil and a collapse in the market, and the less profitable and more heavily regulated shore-based companies had trouble competing. In early 1931, the Hektor factory finally ceased operation, ending commercial whaling at the island entirely.

On 16 November 1928, Hubert Wilkins made the first Antarctic flight from a Whalers Bay ash runway.

Deception remained uninhabited for a decade, but was revisited in 1941 by the British auxiliary warship HMS Queen of Bermuda, which destroyed the oil tanks and some remaining supplies to ensure it could not be used as a German supply base. In 1942, an Argentine party aboard the Primero de Mayo visited and left signs and painted flags declaring the site Argentine territory; the following year, a British party with {{HMS|Carnarvon Castle}} returned to remove the signs.{{cite AV media |url=http://www.spri.cam.ac.uk/library/pictures/catalogue/hmscc1943/ |title=HMS Carnarvon Castle |date=1943 |publisher=Cambridge University |medium=photograph}}

In 1944, a British expedition under Lieutenant James Marr{{cite web|url=http://www.spri.cam.ac.uk/library/pictures/catalogue/hmscc1943/|title=Scott Polar Research Institute, Cambridge » Picture Library catalogue|website=spri.cam.ac.uk|access-date=25 March 2018}} established a short-lived base on Deception Island as part of Operation Tabarin, which was carried out during the Second World War to deny safe anchorages to enemy raiding vessels and to gather meteorological data for allied shipping in the South Atlantic. It also had the effect of strengthening British claims to the Falkland Island Dependencies that had begun being challenged{{cite web|url=http://bas.ac.uk/about/about-bas/history/operation-tabarin/|title=About – British Antarctic Survey|website=antarctica.ac.uk|access-date=25 March 2018}} by Argentina and Chile. Operation Tabarin would deny use of the area to the Kriegsmarine, which was known to use remote islands as rendezvous points, and address a fear that Japan might attempt to seize the Falkland Islands. Following the end of the war, the research begun by Operation Tabarin continued in subsequent years, ultimately becoming the British Antarctic Survey.{{cite web |url=https://www.bas.ac.uk/about/about-bas/history/operation-tabarin/ |title=Operation Tabarin overview |date=2015 |website=British Antarctic Survey – Polar Science for Planet Earth |publisher=British Antarctic Survey |access-date=31 May 2019 }}

In February 1953, as part of a post-war British effort to exert sovereignty over its claimed Antarctic territories, {{HMS|Snipe|U20}} landed a party of Royal Marines on Deception Island to destroy an Argentinian and a Chilean military base; an action known as the Deception Island incident.{{Cite book |last=Howkins |first=Adrian |title=Frozen Empires: An Environmental History of the Antarctic Peninsula |url=https://books.google.com/books?id=VAg1DQAAQBAJ&pg=PA122 |publisher=Oxford University Press |year=2017 |isbn=978-0197533550 |pages=122}}

In 1961, Argentina's president Arturo Frondizi visited the island to show his country's interest. Regular visits were made by other countries operating in the Antarctic, including the 1964 visit of the US Coast Guard icebreaker {{ship|USCGC|Eastwind|WAGB-279|2}}, which ran aground inside the harbour.From the log book of Christopher Malinger, seaman on the USCGC Eastwind

However, the volcano returned to activity in 1967 and 1969, destroying the existing scientific stations. Both British and Chilean stations were demolished, and the island was again abandoned for several years. The final major volcanic eruption was reported by the Russian Bellingshausen station on King George Island and the Chilean station Arturo Prat on Greenwich Island; both stations experienced major falls of ash on 13 August 1970.{{rp|style=ama|p= 294}}

In 2000, there were two summer-only scientific stations, the Spanish Gabriel de Castilla Base{{cite web |title=Gabriel de Castilla |publisher=Shades Stamp Shop |location=New Zealand |url=http://www.newzeal.com/theme/bases/Spain/gabrieldecastilla.htm |access-date=24 May 2009}} and the Argentine Decepción Station.{{cite web |title=4 April – Otter Recovery |publisher=British Antarctic Survey |url=http://www.antarctica.ac.uk/living_and_working/diaries/rrs_ernest_shackleton/antarctic2003_2004/27/index.php |access-date=24 May 2009 |url-status=dead |archive-url=https://web.archive.org/web/20080209225511/http://www.antarctica.ac.uk/living_and_working/diaries/rrs_ernest_shackleton/antarctic2003_2004/27/index.php |archive-date=9 February 2008 }}

Remains of previous structures at Whalers Bay include rusting boilers and tanks, an aircraft hangar, and the British scientific station house (Biscoe House), with the middle torn out by the 1969 mudflows. A bright orange derelict airplane fuselage, which is that of a de Havilland Canada DHC-3 Otter that belonged to the Royal Air Force, was recovered in 2004. Plans to restore the airplane and return it to the island have been made.

President Pedro Aguirre Cerda Station was a Chilean Antarctic base, located at Pendulum Cove on Deception Island in the South Shetland Islands, inaugurated in 1955. It was evacuated in December 1967 when volcanic eruptions forced the evacuation of the base.

Deception Station is an Argentine base located at Deception Island. The station was founded on 25 January 1948 and was a year-round station until December 1967, when volcanic eruptions forced the evacuation of the base. Since then, it has been inhabited only during the summer.

Deception Island has become a popular tourist stop in Antarctica because of its several colonies of chinstrap penguins, as well as the possibility of making a warm bath by digging into the sands of the beach.

After the Norwegian Coastal Cruise Liner {{MS|Nordkapp}} ran aground off the coast of Deception Island on 30 January 2007, fuel from the ship washed into a bay. Ecological damage has not yet been determined. On 4 February 2007, the Spanish Gabriel de Castilla research station on Deception Island reported that water and sand tests were clean, and that they had not found signs of the oil, estimated as {{convert|500|to|750|L|usgal impgal|abbr=on|lk=on|disp=x| of light diesel (}}).

Deception Island exhibits some wildly varying microclimates. Near volcanic areas, the air can be as hot as {{convert|40|C|F|0|abbr=on}}, and water temperature can reach {{convert|70|C|F|0|abbr=on}}.{{Citation needed|date=February 2010}}

Eleven terrestrial sites have been collectively designated as an Antarctic specially protected area (ASPA 140), primarily for their botanic and ecological values, because the island has the greatest number of rare plant species of any place in the Antarctic. This is largely due to frequent volcanic activity creating new substrates for plant colonisation:{{cite report |section=Parts of Deception Island, South Shetland Islands |title=Management Plan for Antarctic Specially Protected Area No. 140 |id=Measure 3, Appendix 1 |publisher=Antarctic Treaty Secretariat |year=2005 |section-url=http://www.ats.aq/documents/recatt/Att242_e.pdf |access-date=2013-09-28}}

• Collins Point (site A) contains good examples of long-established vegetation, with high species diversity and several rarities.
• Crater Lake (site B) has a scoria-covered lava tongue with a diverse cryptogamic flora, and exceptional development of turf-forming mosses.
• An unnamed hill at the southern end of Fumarole Bay (site C) has several rare species of mosses that have colonised the heated soil crust close to a line of volcanic vents.
• Fumarole Bay (site D) is geologically complex with the most diverse flora on the island.
• West Stonethrow Ridge (site E) supports several rare mosses, liverworts, and lichens.
• Telefon Bay (site F) has all its surfaces dating from 1967, thus allowing accurate monitoring of colonisation by plants and animals.
• Pendulum Cove (site G) is another known-age site being colonised by mosses and lichens.
• Mount Pond (site H) contains exceptional moss, liverwort, and lichen communities.
• Perchue Cone (site J) is an ash and cinder cone with rare mosses.
• Ronald Hill to Kroner Lake (site K) is another known-age site being colonised by numerous cryptogam species, and with a unique algal community on the lake shore.
• South East Point (site L) supports the most extensive population of Antarctic pearlwort known in the Antarctic region.

In addition, two marine sites in Port Foster have collectively been designated ASPA 145, to protect their benthic communities.{{cite report |section=Port Foster, Deception Island, South Shetland Islands |year=2005 |title=Management Plan for Antarctic Specially Protected Area No. 145 |id=Measure 3, Appendix 2 |publisher=Antarctic Treaty Secretariat |section-url=http://www.ats.aq/documents/recatt/Att284_e.pdf |access-date=2013-09-29}}

Baily Head, a prominent headland forming the easternmost extremity of the island, has been identified as an important bird area (IBA) by BirdLife International because it supports a very large breeding colony of chinstrap penguins (100,000 pairs). The {{convert|78|ha|adj=on|abbr=on}} IBA comprises the ice-free headland and about {{convert|800|m|mi}} of beach on either side of it. Other birds known to nest at the site include brown skuas, Cape petrels, and snowy sheathbills.{{cite report |section=Baily Head, Deception Island |year=2012 |title=BirdLife Data Zone: Important bird areas |publisher=BirdLife International |url=http://www.birdlife.org/datazone/sitefactsheet.php?id=29403 |access-date=2012-12-09}}
